The'~nstructions ~etail the method by which a tank is to be opened'; ~urged, inspected, sand blasted cleaned, lined, closed and tested% . ' The following summarizes thei lining Process: 1 The ent~ "I ~ ~ · 're interior surface of the empty and isolated tank is cleaned and then~-'sandblasted~to a white-metal condition. Sanding residue and othe'r particulates are removed before the tank is lined· During the cleaning ~rocess, the vapors inside the tank are exhausted and fresh air is pumped into the tank. This purging process continues fpr as long as workers are in the tank. No one shall be permitted to enter the tank unless the concentration of vapors inside the tank is 10 percent or less than the LFL (lower flammable limit). The vapor concentration and oxygen level shall be monitored throughout the operation. 2. All perforations and thin spots in th~ tank walls are reamed until the edges of the resulting holes are a minimum of 1/8 in. thick. The holes are plugged, then sealed with fiberglass matte and resin. 3. Prior to lining application, a 1/4 in. thick steel striker plate is installed to the.bottom of the tank, directly below the fitting used to gauge the liquid level inside the tank. 4. A commercially available spray gun is used to apply a preheated mixture of resin and curing agent onto the interior surface of the tank. The lining is allowed to cure and the surface is inspected using a holiday tester to detect any air pockets, pin-holes or voids in the lining. All holidays are repaired by additional application of the resin system. 5. The cured, holiday-free surface is further inspected using a magnetic thickness gauge and a hardness tester to enS~ure a uniform and consistent coating. The lining shall have a minimum dry film thickness of 1/8 in. and shall have a minimum Barcol hardness of 90. 6. After the thickness and hardness measurements are completed, the tank is closed and subjected to a positive air pressure to check for leaks.

Introduction The following is Sessions's confined space entry procedures. This is not intended to be the Sore source of safety information and proCedures regarding Sessions's safety procedures. The employee must understand and review this entire safety manual in addition to this section to be fully capable of eva~uating hazards and protecting his health and safety I, Applicable Standards - APl 1631 and NLPA 631 APl 1631 and NLPA 631,4th Edition must be reviewed for additional safety, proCedural, information. NLPA 631 and APl .1631 are referenced in the federal and state regulations and may be required to be followed in some jurisdictions. ReferenCed standards in both publications must be consulted to insure safe procedures. This manual is intended to be a supplement to NLPA 631 and APl 1631 as well as the referenCed standards in both these publications. I. Barricading and Securing the Site Prior to beginning any work, the site should be safeguarded from traffic and sources of ignition for at least 25' in all directions around the perimeter of the work area or as determined necessary by the job supervisor. The job supervisor should evaluate potential hazards prior to deciding the perimeter location of the barricade and provide a sufficient perimeter and barricade to protect the workers. No smoking signs should be placed along the perimeter of barricade. The exact number and location of these signs should be determined by the job supervisor. A good rule of thumb for the number of No Smoking Signs would be every 8 to 10 feet along the perimeter of the barricade. Usually, plastic fence, caution tape, or some other appropriate barricade deviCes can be used. The exact type should be selected by the job supervisor and will depend upon site conditions and hazards. I. General Site Safety_ Considerations and Procedures A site safety plan must be completed for each site (see the appropriate section of this manual for the site safety plan and appropriate information). Hard hats must be worn by all personnel when performing operations and ear plugs must be worn whenever the air-compressor is running or when exCessive noise may be generated by the operations. Each moming, a tail gate meeting will be conducted by the site supervisor to discuss the operations which will be performed during the day and safety procedures which will be implemented to insure the workers safety. I, Tank Isolation All lockout will be performed pursuant to CCR Title 8 including the following: A. Electrical Tag/out Lockout Prior to beginning work on the tank(s), electricity to pumps and other equipment attached to the tank must be turned off and secured against reactivation. This is known as locking out. This work will be carried out under the direction of job site supervisor. Lockout consists of locking or secudng electrical switches in the open position so that equipment cannot be accidentally turned on while you are working in the tank. Tags are also used in COnjunction with lockout equipment. The tags have a wdtten waming not to remove the lock or turn on the electrical equipment so that equipment is not accidentally turned on by personnel who may not be aware that the equipment has been "locked out". Usually, the only electrical equipment that needs to be locked out would be the actual pumps that supply fuel to the dispensers. Occasionally, there will be additional equipment such as in tank monitors. Use the following procedure to insure proper lockout and tagout of e~ectdca! equipment which is COnnected to the tank: 1) Notify all personnel involved in project or involved in tank operation/maintenance including tank owner/tank operations manager, COntractors/subcontractors, and all company employees. 2) Determine what electrical eqUipment is on the tank and needs to be locked and tagged. In underground tanks, the turbine is the most common electrical equipment which could still operate in the tank; however, other devices which could be activated will have to be locked and tag. 3) Disconnect the power source for all equipment 4) Place a key lock on the switch/breaker so it cannot be accidentally turned on 5) Tag all switches which have been disconnected and locked with tags that state the following: "Danger ..... Do not operate" and which also state "Do not remove this tag" A. Isolation of Siphon and Product Lines Siphon Lines If two tanks are siphoned together, the siphon line must be isolated. You should ask the station manager where the siphon line might be located if it is not visible or excavated. The line must be disconnected at a union and capped and blanked on both sides prior to beginning any tank work or transferring fuel and an appropiate tag warning not to remove the cap must also be applied to the cap. Vent and Vapor Recovery Lines Vents and Vapor Recovery Lines will need to be checked pdor to beginning work. If the vents are manifolded, the lines must be isolated to insure vapors from one tank are not drawn into another that you are working. This is especially true when a tank is manifolded to tanks which will remain in service dudng the work. Vapor Recovery lines can be isolated by commonly removing an extractor fitting/ball float and placing a plug in the extractor where the vapor recovery system enters the tank. Vents and Vapor Recovery Systems must also need to be checked again when vapor freeing to assure that the tanks have been Isolated (see vapor freeing section). As a final isolation step, after the tank has been initially cleaned of liquid residuals, all pipe inlets in the tank (except those used for ventilations and entry access) are to be blanked from the inside pdor to performing any additional work in the confined space. I. Fuel Transfer 2 A. Checking the Amount of Fuel and for Water The amount of fuel in each tank should be documented in the job plan sheet information prior to fuel transfer. The manager should have a gallonage chart that can determine the exact amount of fuel in each tank. It is important to make this calculation for both the emptying and receiving tank before initiating fuel transferring because you do not want to overfill a tank accidentally. Prior to initiating transferring, make sure that amount of gallonage will fit into the tank that you are going to transfer fuel to. Overfilling a tank will cause a potentially explosive situation, ground pollution and loss of valuable product. A. Safety Considerations for Fuel Transfer While transferring fuel, explosive gas fumes are forced into the air which any type of spark or open flame may ignite. Therefore, it is important that you treat this part of the operation with extreme care. THERE IS TO BE ABSOLUTELY NO SMOKING OR OPEN FLAME WHILE TRANSFERRING FUEL. THERE IS TO BE NO OTHER WORK SUCH AS JACK HAMMERING, GRINDING OF TANK TOPS,, USING A PICK AX, SLEDGE HAMMER, ETC., WHILE THE TRANSFERRING OF FUEL IS TAKING PLACE. Both containers must be properly bonded and grounded when transferring from one container to another container. The transfer pump must also be properly bonded and grounded and must be an air driven explosion proof type pump. 2 40BC Halon fire extinguishers should be located around the transfer area. A. Fuel Transfer Procedures Place the solid copper drop line into the tank that you are going to transfer product out. Connect the hose to the copper drop tube and connect the hose to the transfer pump. Connect a hose to the outlet side of the pump and connect the end of this hose into the short 5' copper tube. The short 5' copper tube should be placed in the tank or drum where the liquid is to be transferred. If there is water present in the tank, the water should be transferred into a drum and separated from the gasoline. Once the water has been transferred, the remaining gasoline can be transferred to the tank or another drum. As much liquid as possible should be transferred out. After transfer is complete, there should be less than an 1" of product remaining. If you have taken the turbine out or if there is an opening on each end of the tank, you should gauge both ends to determine which end is the Iow end of the tank. Whenever possible, you should always pump from the Iow end of the tank. Remember, prior to begi0ning the transfer operation, the containers and pumping equipment must be properly bonded and grounded. Be wary of bonding to water lines for ground sources because many of these lines are now constructed of PVC or non conductive material. The best ground is a copper grounding rod that you actually drive into the ground. The job supe~/isor should determine the best ground source. I. Excavation A. Safety Considerations 1. Safety Equipment Check List Barricades (enough to block off working area) Toe Guards Safety Goggles Shoring Pins to Lock Air Lines to Jack Hammer Pins to Lock Air Lines to Air Lines Ear Plugs 1. Air Monitoring During excavation, it is possible that the soil may be contaminated and conditions may occur where hazardous vapors may be present. The excavation area must be continuously monitored for oxygen and explosion levels if hazardous vapors are present. A. Procedure for Excavation Once you have determined where you are going to dig, mark on the ground with chalk a 5' X 5' square at the center of the tank. If necessary, saw cut the area that you have marked. While breaking concrete, cut and remove all exposed rebar. Cut wire and rebar in a manner that does not leave sharp or jagged edges that could cause an injury. Tape over any jagged edges that cannot' be eliminated. If necessary, construct shoring as you excavate. Always pile excavated soil away from the hole in such a manner that it cannot roll back into the hole. Never transfer fuel or purge vapors while breaking concrete or asphalt. A combustible gas indicator must be used to check for hazardous vapors in the area during the excavation process. If hazardous vapors are detected, all open flame and spark producing equipment within the vapor area must be shut down until a safe condition is achieved. If electrical equipment is to be used in the vapor area, the electrical equipment used in the area must be explosion proof (Class I, Division I, Group D). Ear plugs and safety glasses must also be worn whenever an air compressor is operating and when performing jack hammer operations. In addition, hard hats must be worn whenever entering an excavated area. · Removal of Flammable Vapors A. Preliminary Safety Considerations 1. Vapor dispersal location Prior to performing any cutting or hot work on the tank, the tank must be thoroughly purged with air to remove flammable vapors. The concentration of flammable vapors in a tank may go through the flammable range before a safe atmosphere is obtained. Therefore, it is necessary that precautions be taken to eliminate the possibility of discharge of static electricity during the gas freeing procedures. Special consideration must be given to ensure that vapors are not vented into area where they could produce a hazardous condition. The air compressor must be located in a position where the intake will not suck in hazardous vapors. Usually, the best location for the air compressor and other equipment that is capable of producing a source of ignition is upwind from the location where vapors will be dispersed. Other factors that should be considered prior to vapor freeing include the location of electrical lines and other sources that may produce a source of ignition. Vapors should never be dispersed under a covered area, such as a station canopy or your trailer. 1. Gauging the Tank Prior to beginning the purge, gauge the tank to make sure that the liquid level is 1" or less. As much liquid should be pumped out of the tank as possible and the liquid level in the tank must be at 1" or less prior to initiating the purge. A. The Eductor Procedure ventilation of the tank can be accomplished by an air driven eductor type air mover. The eductor is placed on the fill tube and essentially draws a vacuum on the tank and sucks air from the vent through the fill. The eductor must be properly bonded and grounded to prevent the possibility of static electricity generation and discharge. The intake opening, the vent, must be unblocked to prevent a vacuum that could collapse the tank. When using this method, the fill (drop) tube must remain in place to assure that the vapors will be drawn from the bottom of the tank. Gasoline vapors are heavier than air and the drop tube assures that ventilation is occurring at the bottom of the tank where gasoline vapors are expected to accumulate. An extension must also be used to discharge vapors above the tank a minimum of (12) feet above grade. This extension helps insure that vapors do not build up at ground level. A safe working atmosphere around and within the tank will occur if the following safety precautions are practiced during purging using VACUUM TYPE PROCEDURES provided that the eductor is properly grounded and vapors are being dispersed in a manner that they are not accumulating in one area or are exposed to a sources of ignition. Suitable grounding must be provided to prevent a spark from igniting any gasoline vapors in the immediate area. 1. Special Equipment AIR MOVER: Venturi type Model "N" with a 12' X 4"diameter aluminum drop tube welded to the convergent collar. A 4" X 9" nipple and a 633©D 4" Karo Lock threaded into the 4" female thread of the model "N" venturi. This will allow the air mover to be locked in place on the 4" male OPW adapter on the tanks fill pipe, creating continuity with the tank and the air mover which aids in the grounding of static electricity. GROUND STRAP(100' lengths): Connect the ground wire to the two (2) lug twist lock coupling where the 3/4" air hose is connected to the eductor. Attach the other end of the ground clamp to the nearest suitable ground source. GROUNDING ROD: When grounding sources are not accessible, a steel grounding rod shall be driven into the ground to a minimum depth of 3 feet and used as a grounding source. EXpLoSION METER/OXYGEN METER: Shall be an explosion proof device recommended for Division I.Class I Group D type of environments. A. Vent and Vapor Recovery Check and Isolation Once you have begun the purge, make sure that the vents and vapor recovery are not plugged or manifolded together. To check the vents, place your hand over each vent until you feel suction or air with only one purge unit on at a time. If you feel a significant amount of suction or air from one vent, then you probably have adequate air flow (you should feet a vacuum if you are using an eduction method; if you are using an induction method you feel air being blown out of the vent). If you feel suction or air from more than one vent with only one purge turned on,.then the vents or vapor recovery lines are manifolded and will need to be isolated if one tank is operational (operational means that one of the tanks is in service or full of product). Sometimes, it may also be necessary to run temporary, separate vents from one or both of the tanks (Note: the tanks still must be isolated from one another). If two tanks are manifolded at the vents and you are working on both tanks simultaneously, you can place a purge on both tanks and leave the tank vents manifolded provided that you perform no work on either tank until both tanks are purged to safe levels. In other words, if you have two manifolded tanks and one is safe to cut and the other is not safe to cut, you cannot cut into either tank until both tanks are at safe levels. Obviously, you cannot leave an operational tank (a tank that is still pumping product) manifolded to a tank that you are attempting to purge. If you are using an eductor type system, this will cause vapors to be continuously drawn into the tank that you are working on and create a potentially hazardous situation if you are using an eductor system. In an induction system, it will cause a large amount of vapors to be discharged constantly dudng the work. Both situations are highly dangerous. Operational tanks must be separated from the tanks you are working on. I. Testina_ Flammable Vapor Concentrations A. Safety Considerations t. Ox:ygenfF_,xploslon Meter lJse An important phase of the operation is the testing of the vapor for flammability in the excavated area and in the tank. Such tests shall be made with a combustible gas indicator that is propedy calibrated for gasoline vapors and thoroughly checked and maintained in accordance with manufacturer's instructions. Persons responsible for testing must be completely familiar with the use of the instrument and the interpretations of the instrument readings. Some explosion meters are very sensitive and may momentarily fluctuate if there are a considerable amount of vapors in the tank. Explosion meters that fluctuate may go from Oto explosive to 0 again within a second or two. If you miss this fluctuation, you may inadvertently cut into a tank that is actually explosive. To avoid this scenario, always look at the explosion meter read out during the entire vapor reading process. If the reading goes above explosive and jumps back to O, do not interpret this reading as a 0 reading - the tank is actually hot (explosive). Additionally, always look at explosion meter reading when purging the explosion meter, if the meter is reading 0 and goes back to explosive while purging the instrument, the tank is still hot. 6 The explosion meter should always be immediately purged after taking a vapor reading. Purging of the instrument basically draw clean air into the instrument so that no gasoline vapors remain in the instrument in between reading's. If you do not purge the instrument, your explosion meter will bum out and need to be repaired or replaced. A combustible gas indicator is used to measure the concentration of gasoline vapor in a tank. This is a delicate instrument and should be used 0nly by personnel who are fully acquainted with its application and use as defined by its manufacturer. The concentration of gasoline vapor in the tank atmosphere cannot be determined by SMELL, VISUAL INSPECTIONS, OR JUDGMENT. Oxygen readings must be taken pdor to taking LEL readings. 1. LEL/OXYGEN Readings and Meanings Hot work cannot be performed until the tank vapor reading at 10% or less of the LEL. Hot work is any work that is capable of producing a spark or other source of ignition. Tank entry will incorporate the use of cutting with an air ddven saber or jig type saw. Under no circumstances should a cutting torch or abrasive wheel be used on the tank. A tank with less than 1.4% gasoline vapor in air is too lean to bum. A tank with more than 7.6% gasoline vapor in air is too rich to bum. A concentration of 1.4 to 7% gasoline vapor in air will bum if ignited. The LEL is a percentage measurement of only the 1.4% vapor concentration. A reading of 100% LEL on the explosion meter means that there is 1.4% gasoline vapor in the tank. A reading of 10% LEL would mean that there is only 10% of the 1.4% gasoline vapor in the tank or .14% gasoline vapor. A reading of 50% LEL would mean there is only 50% of the 1.4% gasoline vapor in tank or .7% gasoline vapor. Do not cut a tank that is above 10% of the LEL. Allow the purging unit to ventilate a half an hour pdor to taking readings with the explosion meter at the eductor. This will prevent your explosion meter from becoming burned out. Calibration The LEL/Oxygen meter must be tested daily to insure proper calibration. This performed with a calibration gas and is performed pursuant to the instruments instructions 1. Oxygen Content For the explosion meter to operate correctly, a minimum of 10% oxygen inside the tank is required. An oxygen reading must be taken pdor to taking an explosion reading to insure that an accurate explosion reading can be obtained and that the oxygen level in the tank is at least 16%. 1. Purge Time If it takes an abnormally long time to purge a tank, there may be a large amount of liquid present in the tank or the ventilation is inadequate. A typical 10,000 gallon tank should be able to be completely purged within 2 to 4 hours. a) For tanks that are taking excessive time to ventilate: check Do you feel air flow around the vent. If so, feel all vents and make sure that none of the tanks are manifolded with operational tanks. Jf the tanks are manifolded with operational tanks, these tanks must be isolated. If you do not feel air flow, the vent may be blocked and you may need to 7 create a temporary separate vent by digging to the end opposite of the fill tank and opening a fitting that will provide air flow into the tank. Remove turbines and pumps and check the liquid level opposite of the till side to see if the tank is tilted away from the till. If there is liquid present, pump out as much liquid as possible but to at least 1" or less. Removal of pumps and turbines also creates an extra opening and will help in ventilation. Sometimes vents are located within a couple feet of the till creating a situation where only a small area of the tank is being ventilated. If you suspect this is the case, remove turbines or dig to the opposite end of the tank and locate a tiffing that can be removed to increase ventilation A. Testing Flammable Vapors when using an Eductor System When purging is being performed by an eductor type air mover, readings shall be taken by placing the oxygen/combustible gas indicator through a probe hole located at the bottom and pdor to the air located in the the eductor. The location of hole is important because if the hole is located above where the air from the air compressor is being placed into the eductor you will obtain a false reading. This is because fresh air from the air compressor is being mixed into the air from the tank inside the eductor. This mixture of compressor air and tank air will actually cause your explosion meter to read a lower LEL than actually exists inside the tank. The probe access must be located prior to the air mixture location in the eductor. Readings of tank vapors which are 10% or less of the LFL must be obtained before the tank is considered safe for opening. I. =' Cuttim3 the Access Hole in the Tank A. Safety Considerations 1. Fire and Explosion Considerations Under no circumstances, should a torch, welder, grinding wheel, or other equipment that produces a hot enough source of ignition be used on a tank during the opening process. This type of equipment can and will cause any flammable residues in the tank to ignite and could cause a fire or explosion to occur even though the tank has been purged to a safe LEL level. Remember, flammable liquids are still flammable no matter what LEL level is achieved. 1. Final LEL Readings and Locations Once a reading of 10% LFL is achieved at the eductor or fill tube, a reading inside the tank must be taken where the access opening is to be cut. This is accomplished by drilling one hole along the perimeter of the area you are going to cut. This hole is not to be drilled until you have achieved a 10% LEL or lower reading at the eductor of fill tube. If the vapors inside the tank are found to be at 10% or less of the LEL at the drill hole, then the opening process may proceed. Under no circumstances, cut any tank that has a reading of more than 10% of the LEL at the drill hole or any other vapor reading location on top of the tank. Prior to the men entering the excavated area to cut the access opening, a reading with the explosion/oxygen meter must be taken to assure that the excavation is vapor free. Excavation areas can sometimes become hazardous when soil contamination or other conditions exist that may cause flammable vapors to accumulate within the excavation area. If vapor readings or conditions exist that indicate flammable vapors may exist in the excavation area, appropriate 8 safety precautions such as respirator protection, air monitoring (oxygen and LEL), and rescue lines may be needed. Fire extinguishers should be located within the excavation area (near and within reach of the cuffing area) and in other areas around the job to insure that they are readily accessible in the event of a fire. All extinguishers must have the pin pulled. One man should stand on top of the excavation at all times while the access plate is being cut and standing fire watch with a halon fire extinguisher with the pin pulled. A. Special Equipment DRILL - Air Driven WATER - In container that can be used to pour water on cutting blade during cutting and drilling EXPLOSION 'METER - Niosh Approved FIRE EXTINGUISHERS - Halon (2) 80B:C BODY HARNESS A. Cutting Procedure Once you have obtained a safe LEL reading at fill or eductor, mark with a crayon a square opening on the top of the tank (at the end cap for fiberglass tanks and never into a rib on an FRP tank) with minimum dimensions of 24 inch by 30 inch. Some localities and states may require larger openings and should be consulted to insure compliance. Do not mark an opening that in a location on top of the tank that is within 6 inches of any weld or if the overlapping lid that is to be used to close the tank will overlap a weld. The overlapping of welds or seams when closing a tank may cause the lid not to seal. WARNING: VENTILATION AND PERIODIC TESTING FOR FLAMMABLE VAPORS MUST CONTINUE THROUGHOUT THE ENTIRE LINING OPERATION. PERSONNEL SHALL NEVER ENTER A TANK WITHOUT PRIOR ADEQUATE VENTILATION, AND VENTILATION SHALL CONTINUE WHILE PERSONS ARE IN THE TANK. DURING TANK CUTTING OPERATIONS, AIR PRESSURE LESS THAN 5 PSI MUST BE MAINTAINED TO PREVENT A BLOW OUT WHEN BLOWING AIR INTO THE TANK DURING GAS FREEING PROCESS. TO AVOID BUILD UP OF FLAMMABLE VAPORS, AIR MUST BE DRAWN FROM THE TANK BO'FI'OM THROUGHOUT THE CUTTING OPERATION IF AN EDUCTOR METHOD IS BEING UTILIZED. After you have marked the area to be cut, drill one hole in one of the comers of the marked area. If you are using an extremely long cutting saw, you may want to drill one hole that is centered along the line of any two comers. This will give you extra room to work with the saw which might be needed if the excavation area is small. Cool the drill using water and pouring the water directly on the drill bit during the drilling process. Don"( be scared to used too much water. It's better to use too much than too little. The cooler the drill the better. Take a Oxygen/LEL reading directly from the drill hole. If the reading 10% of LEL or less, you may proceed to drill holes in the remaining 3 comers. LEL readings shall be taken at a minimum of 15 minute intervals during the cutting process. Using a saw blade that will fit into the drilled holes, begin cutting the tank. Use as much water as is necessary to keep the saw blade cool during the cutting process. Near the end of the final cut, it will be necessary to lift the plate that has been cut from the tank with a screw ddver or other tool so that it can be grasped by a man with both hands to prevent it from falling into the tank. The plate must not be allowed to fall into the tank as it could create a spark or source of ignition. I. Confined Space Procedures The following procedures and/or limitations apply to all of Sessions's confined space entry operations: A. Air Monitoring 1. Oxygen and LEL Levels Pdor to performing any work in the confined space, the tank must be checked for LEL by checking both the area of the bottom, middle, and top of the tank at the entry hole and fill. The readings must be less than 10% of the LEL before proceeding with any other work. Oxygen reading must be at least 19.5%; but not more than 23.5% oxygen. Tests with the combustible gas indicator and oxygen monitor must be performed continuously in the tank to insure that the tank vapors and oxygen content are in the safe range for all confined space operations. All monitoring will be performed by the CIH/CSP. Entry into a confined space is prohibited until initial testing of the atmosphere has been done from the outside. Appropriate tests must be made to insure that the atmosphere is safe. The tests performed must include oxygen concentration and flammability. The test shall be taken at the tank entry hole at the bottom, middle and top of the tank exterior and noted on the confined space entry permit. Entry into a confined space for any type of work may not occur when tests indicate the concentration of flammable gases in the atmosphere is greater than 10% of the lower flammability limit (LFL) or when oxygen is below 19.5% or above 23.5%. Equipment for the continuous monitoring of gases and vapors must be explosion proof and equipped with an audible alarm or danger signaling device that will alert employees when a hazardous condition develops. Instruments used for testing the atmosphere in a confined space must be selected for their functional ability to measure hazardous concentrations. l. Daily Calibration of the LEL/Oxygen Meter Instruments must be calibrated in accordance with the manufacturer's guidelines or manuals and must be by the ClH/CSP. Each calibration must be recorded by the employ on a log sheet or on the confined space entry permit Confined spaces which have not been monitored for LEI/OXY pdor to entry are not to be entered by personnel. CO Monitoring for Air Supply The CO monitoring device must be used whenever airline supplied respirators are to used by entry personnel. The CO monitor must be checked on a daily basis per the instructions. 10 1. Employee Training in Monitoring Equipment EmplOYees which will be performing monitoring will be trained in the use and calibration of the monitoring equipment. A. Ventilation ventilation must be maintained at all times when conducting confined space operations. Do not turn ventilation off whenever anyone is about to or has entered a confined space. it should be recognized that if ventilation is stopped and the tank was in the safe range, hazardous vapors can build back up. Many of the accidents in confined space entry have occurred due to not maintaining ventilation. Remember, just because you have achieved a safe atmosphere does not mean that a safe atmosphere can be maintained without ventilation. Ventilation and air monitoring are the keys to keeping a safe work environment. Confined spaces which are not being constantly ventilated (or ventilated prior to entry) must never be entered by personnel. All ventilation equipment will be air driven or be electrically rated explosion proof for Class 1, Division 1 locations. A. Tank isolation All lines and other openings that can leak liquids (or vapors) must be blanked to ensure no liquids or vapors can enter the tank during the lining or repair operation and as desc~be ea~lie~ in this manual. A. Confined Space Entry Permit A confined space entry permit must be completed and signed by the job site supervisor prior to personnel entering the tank. The confined space entry permit must be posted on the job site. A copy of the confined space permit that may be utilized for this type of work is contained in section VI. Both vapor and oxygen readings as well as daily calibration of the meter are to be documented on confined space permits. Readings of vapor and oxygen shall be taken continuously. Initial LEL/Oxygen readings shall be recorded on the confined space entry permit and shall be recorded at least every hour after the initial reading on the confined space entry permit. Once the confined space work is complete, these permits should be placed in the applicable section of this manual and reviewed with employees at least annually as part of the employers confined space training program. A confined space cannot be entered until a confined space entry permit has been issued. The confined space entry permit expires after 8 hours, if ventilation is stopped, upon completion of an assignment, or upon determination of the job site supervisor. A completion of an assignment is completion of task such as cleaning. The next assignment would be to sandblast which would need a separate permit. After sandblasting, the next assignment might be to inspect the tank which would also require a separate permit. A. Attendant Duties 11 There will be a minimum of two attendant(s) who will be disignated by our supervisor when personnel are conducting a confined space entry. As an attendant, you play an important role in ihsuring safety of entry personnel. One of the attendants must always remain near the access opening and in communication with the entrant who is in the confined space. The other attendant must provide support for the primary attendant(the primary attendant is one near the access opening and who is in communication with the entrant) to ensure that that the primary attendant can maintain his repsonsibility to the entrant (which is communication). You must remain outside the confined space during entry operations unless relieved by another authorized attendant. Communications with personnel who are attending the confined space and those that are entedng the confined space play an important aspect of confined space operations. The most important aspect of communication is assuring that the entry personnel are "OK" during confined space operations. This can be established by a process (for example you can see the person lifting a bucket or performing "normal work" in the confined space which is an indication that everything is ~OK". If you see, however, a person laying on the floor with little or no movement you can probably assume that everything is "not OK". Everything is OK if the entrant is performing work as normal. The following are signs that entry personnel are not OK: 1) There is no movement in the confined space (the process has stopped; ie sandblasting, Cleaning, or other process has stopped; but no communication is established to indicate everything is "OK". 2) Entry personnel appear to be staggering or moving in uncordinated or unusual manners. This can be due to number of factors including heat exhaustion (sometimes excessive personnel protective equipment can cause exhaustion), inadequate personnel proteCtive equipment (perhaps the resipirator is not working correctly or supplying enough air). 3) The person appears to be tired. if you believe any of the above might be affecting the entry person, you should request that the entrant exit the space or perform a rescue (if needed) with the mechanical tripod. You can also ask that the entrant give the "OK" hand signal just to confirm that the entrant is OK and to reestablish communication with the entrant.. Another aspect of being an attendant is assuring that the space remains within the' monitoring limitations. As an attendent you are responsible for checking the monitoring to ensure that the LEL./Oxygen remain at safe levels. If at any time during any entry operation, the LEL becomes 10% or more or if the Oxygen is less than 19.5%, you must have the entrant immediately exit the confined space until the condition is corrected. The entry supen/isor must be consulted prior to r~entry so that the cause of the condition can be determined and corrected. It should be noted that while this section is providing information for employee performing monitoring; the monitoring must also be performed by the CIH/CSP when conducting confined space operations. LEL and Oxygen readings must be taken coninuously and you must also record LEL/Oxygen readings on the confined space permit at least every hour. If ventilation is stopped during the entry, you must have the entrant immediately exit the confined space until the ventilation is reestablished. In addition, you must guard against unauthorized personnel getting close or entedng the confined space. A. Rescue Procedures Tdpod Rescues will be performed with the use of the a mechanical device called a "tripod". The procedure for rescue in the event a person becomes ill or unable to exit the confined space is to use the tdpod and the mechanical winch to pull the person from the confined space. Emergency Rescue Team with SCBA As a secondary method of rescue, an SCBA, harness, and a mechanical retrieving device will always be located next to the confined space when ever there is an entrant in the tank. As an attendant, you must make sure that the SCBA and the equipment is setup and ready to use pdor to an entrant entedng a confined space. The other attendent (the one not performing the rescue) must remain outside of the confined space to assist in the rescue entry. The person performing the rescue must enter the tank with the SCBA and be connected to the safety line which is to be attached outside of the tank. A. General Safety Procedures in Confined Space Operations: While there are a number of procedures regarding confined space entry and which will be discussed further in this manual, the following are basics which are the key to safe confined space operations: !) A completed confined space entry permit prior to entry 2) Monitoring LEL and Oxygen pdor to entry and at a minimum of 15 minute intervals dudng entry. If at any time LEL readings are 10% or more of LEL or if oxygen is less than 19.5%, personnel must exit the confined space immediately. 3) Constant ventilation of the confined space during entry 4) Explosion proof Lighting 5) Tank isolation and lockout (see earlier section fortank isolation and lockout 6) Place a barricade and signs which state "Danger Confined Space" around the perimeter of the confined space opening and to insure against unauthorized entry A. Personnel Protective and Safety Equipment for Confined Space Entrant Personnel 1. Air Supplied Respirator Personnel entering the tank must be equipped with positive pressure air supply equipment with full face enclosure when performing cleaning, sandblasting, and spraying operations, l. Harness and lines Personnel must wear a safety harness connected to a safety line held by an attendant outside the tank. A mechanical device such as a tripod must also be available to insure personnel can be pulled out of the tank. 1. Flash Suit A fire retardant coverall and fire retardant head protection must be worn by entry personnel when flamable material may be present in the tank and when conducting cleaning operations. Disposable clothing impervious to product may be also be used provided that it is worn under or over the fire retardant suit. I. Cleaning Procedure 1. General Safety Considerations Air supplied respirators, harness, and flash protection must be worn by entrant personnel who will be conducting cleaining operations Ventilation must be maintained throughout the cleaning operations. The tank must be continuously monitored for oxygen and LEL levels during tank work. If an unsafe atmosphere exists, entry personnel must immediately leave the confined space..An unsafe atmosphere means any atmosphere that is below 19.5% oxygen or above 23.5% oxygen or an atmosphere that is above 10 percent LEL. Prior to entering the tank, a visual inspection of the tank interior must be performed from the outside of the tank to determine that no pockets of liquid gasoline remain. As much liquid as possible must be pumped out of the tank interior prior to entry. Under no circumstances, should there be more than 1" of liquid left in the tank. 1. Positive Pressure Air to the Body An air belt that provides air pressure to the body must be used underneath the coverall. Usually, the best way of assuring good air flow to the body with an air belt is to first put a disposable uniform on underneath the fire suit. The disposable uniform should be taped at the ankles and wrists and around the air line that supplies the air to the air belt. If suited up correctly, the disposable suit should blow up like a balloon when air is supplied to the air belt. The fire suit can then be worn over the disposable uniform. Positive pressure prevents keeps you cool and reduces heat exhaustion. 1. Electrical Grounding of Clothes All clothing and/or personnel entedng during tank clean operations must be securely grounded to eliminate the possibility of the discharge of static electricity from clothes. WARNING: Fiberglass tanks require special consideration in adequately grounding personnel. FRP tanks can build up extremely large charges of static electricity. In a fiberglass tank, the personnel must be attached to a ground wire that is. grounded outside the tank. A product known as a clothing and boot stat must be used to dissipate static electdc from clothing. The ground line must connected to an adequate ground source and should be taped to the air line to help prevent entanglement. 14 i 1. Explosion Proof Lighting Only use a light in the tank if absolutely necessary. If a light is necessary, an explosion proof light must be used when conducting cleaning operations. Under no circumstances, should non explosion proof lights be used. Portable non explosion proof lights should not be on the truck or even used outside of tank to light the top of the tank. These lights can be accidentally knocked into the tank. More accidents have occurred because of non explosion proof lights than any other cause. Be sure that the explosion proof light is secured in a manner that insures that it will not accidentally drop or fall into the tank. Never use a non-explosion proof light in or around a tank. Always check the cord to insure it is not worn or frayed. Do not use explosion proof lights that have damaged cords. Always check for proper poladty of electricity by using a poladty check instrument. After you have checked and confirmed that the electricity has correct polarity, check the light again for proper poladty pdor to putting it into the tank by touching it to the top outside portion of the tank that is away from the access opening: If the light generates any sparks, the light should not be used or the electricity should be corrected. The light should always be checked for poladty prior to personnel entedng the tank. 1. Spreading of Floor Dry Pdor to sludge removal and to entry, a covedng of floor dry must be spread directly under the access opening and as far as practical in all directions to cover any remaining liquid residuals. Upon entering the tank, the floor dry must be spread over the entire sludge area, starting from under the access opening, working from one end of the tank to the opposite end of the tank. The floor dry must be spread in enough quantity to absorb all liquids. Floor dry acts as a fire and vapor suppressant and is necessary to protect the health and safety of the workers. 1. Cleaning Procedure Using an aluminum scoop shovel, start removing the mixture of floor dry and sludge directly under the access opening,clearing a space to stand while working. An explosion proof drop light, Class I Group I Division D can be used to help see while removing sludge. It is recommended that the tank be cleaned without the explosion proof light, letting your eyes adjust to the natural lighting inside the tank. Once a clean area is achieved under the access opening, begin working to the end caps of the tank, shoveling up the sludge into buckets, handing buckets to the worker at the top ofthe tank. Sludge should be disposed in approved containers. Once the mixture of sludge and floor dry is thoroughly removed from the entire floor area, spread another thin layer of floordry throughout the tank bottom. Using a sweep broom, sweep the floor dry back and forth with the circumference of the tank drying the remaining moisture off the surface. At all times while the worker is inside the tank removing sludge, a worker on the top of the excavation must stand a firewatch with the fire extinguisher having the pin pulled from the tdgger mechanism. This worker must be made aware that a fire could occur and should take this job very seriously and be alert at all times. This workers action and response in an emergency could be the difference between minor injudes and very sedous injuries. Hose lines for air masks should be kept clean. If a workman notices any odor while weadng his hood respirator, he should leave the tank at once and not re-enter until the condition is corrected. In the event of any indication of respiratory equipment not working prcpedy, the workman should immediately leave the tank. 15 All workman should wear clean clothing from the skin out and approved impermeable gloves and boots of good quality and in good condition. A twin organic vapor cartridge respirator should be used by the workers outside the tank handling and disposing of the sludge. Clothing should be changed (and laundered) and a bath should be taken every day, either at the end of the day's work or when the job is finished. If at any time the clothing gets soaked with gasoline or sludge, the workman must bathe at once and put on clean clothes. At the end of each day, and after the job is complete, respirators, boots, gloves, and tools should be inspected, cleaned and properly stored. Once the tank is thoroughly cleaned, lines should again be checked to insure that all lines which could leak vapors and gasoline vapor back into the tank have been properly isolated and Plugged. If there are additional siphon or product lines, or pumps, these lines must be isolated in manner that will insure that vapors or liquids will not flow back into the tank. All suction lines shall be removed and plugged to prevent gasoline vapors reentering the tank. The tank is now ready for the sandblasting procedure. Again the tank interior shall be checked with the explosive meter from one end to the other of the tank along the floor, 12" from the bottom of the tank. Sandblasting must not start until LEL/Oxygen readings have been taken to insure that the LEL/Oxygen levels are at safe levels.. Sludge present in tank bottoms will need to be managed as hazardous waste. The containers that the sludge is placed in should be labeled and manifested to hazardous waste disposal facility, where appropriate (,see the appropiate section of this safety manual for hazardous communication and material labeling) 1.

Sandblasting and Surface Preparation A. Safety Considerations and Requirements The tank shall be monitored for LEL and Oxygen continuously during abrasive blast operations. In addition, ventilation must also be maintained continuously when conducting sandblast operations. Do not place the sandblaster in the tank until the tank has been entered and tested for LEL and the presence for liquid. Abrasive blasting does generate sparks. Therefore, extreme care must be taken pdor to placing the sandblaster in the tank and proceeding with sand blasting operations. Once the man has checked the tank inside for flammable vapors and liquids, he should signal for the sandblasting hose and equipment if conditions within the tank are safe. If the man exits the tank, he must perform this vapor reading test again inside the tank pdor to the sandblast hose being placed in the tank or initiating the sandblasting operation to insure that conditions within the tank have not changed and are still safe. A. Hot Work Permit Pdor to performing any abrasive blast operations, a hot work permit shall be issued. A. Blasting Helmets Abrasive blast operators must wear approved sandblasting helmets connected to a Clean air source, The helmet must be approved for sandblasting and have a built in hard hat with a double lenses. These helmets should be approved by the U.S. Bureau of Mines and connected to a source of clean compressed air with a carbon monoxide alarm device. A. The Deadman The deadman is a device that allows the sandblasting operator to shut down the sandblaster by remote control. This provides safety protection to the operator. Without a deadman, sandblasting can be very dangerous. Consider the possibility of a man inside the tank who collapses, faints, or falls and is within the tank with the nozzle blasting which in effect is an automatic machine gun. There have been fatalities caused by such incidents. With the remote control deadman,'the moment he releases his grip on the nozzle, the sandblaster shuts down preventing possible accidents. A. Ear Protection Improper headng protection can cause permanent hearing damage or loss during blasting. Hearing can be damaged in less than 1 to 2 hours with no headng protection during blasting. Approved headng protection must be wom during blasting to avoid headng damage and loss. Never sand blast a tank without proper hearing protection or if you feel that your headng ' protection is not adequate. If you have a ringing sensation in your ear during or after sandbtasting, then you may not have sufficient hearing protection and the job supervisor should be contacted to correct the problem. ]'7 A. Sandblast Hose Condition Sandblast hoses should be inspected prior to each use to insure that all hose couplings have pins and that the hose is not worn..Hoses that show signs of fatigue such as dry rot or weathering should replaced. If a hose blows out during use, the entire hose length should be replaced because the entire hose is probably worn out. Hoses must be kept in good condition. Improper maintenance of sandblast hoses can lead to sedous injuries. A. Grounding of the Blast Hose The blast hose and nozzle must be grounded to a proper source to dissipate static charges ,A. Clothing Blasting and personnel working on tanks must wear rubber boots, fresh air masks and harness. Safety goggles must be worn by all other persons near any 'blasting operation. The clothing worn by blasting personnel should be adequate to protect the worker from flying particles and debds. Usually, a thick cotton coverall is preferred dudng sandblasting operation to protect the general torso, arm, and leg area. Filter type air respirators must be worn by personnel who may be attending the confined space and who are exposed to blast dust environment. Adequate eye, face, and other protection for personnel from flying particles shall also be provided in any blasting operation. Dust masks are not to be used by personnel for tank blasting operations. Only approved air supplied respirators should be used for blasting operations. A. Line Isolation As mentioned eadier, all remote lines of any type going into the tank should be removed and plugged or fitted with plugs to prevent vapors or liquids from reentering the tank interior. These lines must be isolated pdor to placing the sandblast hose in the tank. A. Other Considerations If there are other tanks that are to remain operational (full of product) dudng the sandblasting operation, you must make sure that the tank is isolated and vents, siphons, and other product lines are completely plugged to insure that vapors or liquids do enter the tank that you are working on. If at any time a fuel delivery is to occur dudng the blasting operations, blasting operations shall cease pdor to and until the filling operation is complete. The tank will need to be again checked with an explosion meter pdor to commencing any sandblasting to insure that the tank atmosphere is safe. A. Special Equipment 1. Safety Equipment 18 Carbon monoxide alarm system White disposable plastic overalls White cotton gloves Blasting helmet with positive air displacement Safety harness Ear protection Oxygen indicator Explosion Meter l. Sandblasting Equipment Sandblaster with deadman control and light Sand Nozzles BUCKETS Four (4) plastic BROOM, One (1) Regular, One Fine bristle push broom SHOVEL- One (1) aluminum scoop VACUUM One (1) Shop Dry Vac A. Sandblasting Procedures Check the oxygen content and the LEL prior to entering the tank. The operator must have the sandblast hood on upon entering the tank. Check the LEL and oxygen content 12" above the floor level from one end of the tank to the other. Do not place the sandblast hose into the tank until the LEL readings have been taken and it has been determined that the tank is safe and free of flammable vapor and liquids. If liquids or flammable vapors are present, do not place the sandblast hose in the tank. The fill tube should remain in place. Inspect the plugged inlets and lines to assure no product leakage. Inspect the submerge pump to make certain that gasoline is not leaking from it. Warning: Do not place the sandblast hose in the tank until vapor readings indicate that the tank is at a safe level. Warning: Do not place the sandblast hose in the tank if liquids are present. The large funnel should be placed in the access opening at least one (1) foot into the tank with the intake of the funnel facing the side wall. The funnel must be grounded. Ventilation must be maintained throughout the sandblasting process. In addition, LEL and Oxygen must be check at a minimum of 15 minute intervals Personnel entedng the tank must wear approved air supplied respirators for sandblasting, head protection, hearing protection, and a harness with rope connected to tdpod. A. Cleaning the Tank of Sandblasting Media Once the sandblasting procedure is complete, the sand accumulated inside the tank should be removed by a vacuum system or by shoveling the sand into buckets and pulling the bucket out of the tank. 19 Workers in the tank must wear respirator protection that protect from the sandblast dust and harnesses. Men who will be on top that will be handling sandblasting media or that may be exposed to dust, must also wear respirator protection. I, Tank Inspection and Repairs A. Safety Considerations Oudng inspection or repair, the entire interior surface of the tank must be inspected using a light fixture approved for Class I, Division I, Group D Hazardous Locations. Ventilation and monitoring of tank atmosphere must be performed through out the tank inspection and prior to personnel entedng the tank. Remember, if the tanks were cleaned the day before or ventilation was not maintained, the tank atmosphere may be explosive or oxygen deficient if ventilation is not applied to the tank. Organic Vapor Masks, head protection, and headng protection are to be worn-in the tank when conducting an inspection, performing repairs or troweling of the seams with lining material. In addition, the ventilation must be maintained on the tank. Monitoring of the tank for LEL and Oxygen must be conducted continuously. Note: Tank inspections and/or other work are only to be conducted after the tank has been thoroughly cleaned hazardous residuals. Organic Vapor masks are not to be used for tanks which have not been cleaned or for other operations such as cleaning, sandblasting, or spraying. I. Application of Lining A. Clothing and Personnel Protection Personnel entering the tank must wear an air belt, air supplied respirator, rubber resistant gloves, flash protection, and boots, and hamess. An air belt should first be worn undemeath a disposable uniform. The disposable uniform should then be taped at the wrist and ankles and at the air opening. When taped correctly, you should blow up like a balloon when air is applied to the air belt. Personnel who are not entedng the tank; but will be working on top should use organic vapor masks and eye protection. A. Rescue Procedure After you are fully suited, you must wear a harness prior to entering to spray a tank. The rope shall be connected to the harness and to a tripod on top of the tank.. , A. Explosion Proof Light and Equipment Only an explosion proof light may be used for spray operations. The light should be covered with a. oven bag to prevent off spray from building up on the light. The electric to the light must be 20 checked for proper poladty using a polarity tester prior to placing it into the tank and beginning spraying operations. A. LEL and Oxygen Monitoring During spraying operations, the LEL and oxygen content must be taken continously to insure that a safe atmosphere is maintained. A. Maintaining Ventilation ventilation must be maintained through out the spraying procedure. Eductors and other ventilation equipment must be grounded to eliminate the possibility of a static discharge. All ventilation equipment must be explosion proof. A large eductor should be near the access opening to change the air inside and with duct that extends in to the tank to be sure air is circulated into all parts of the tank. It is also recommended that a second eductor be placed on the fill tube to increase and aid in ventilation. A. High Pressure Spray Concerns Never point the spray gun at yourself or anyone else. Never place the tip or gun nozzle in direct contact With any part of the body, or put the hand or fingers directly over the fluid tip. Always shut off power and relieve fluid pressure before attempting to remove the guntip or filter and before removing the gun. Warning: The shutting off of power or of the gun does not relieve fluid pressure. A plugged or clogged lines can contain fluid under high pressure. Always loosen spray fittings slowly and relieve pressure prior to loosening. If a fitting is extremely difficult to loosen, the line may still be under pressure. Do loosen fittings that you suspect may be under pressure Always tighten threaded connections carefully and securely, and handle the hose carefully. Do not allow the hose to kink as this could cause it to rupture. Do not attempt to exceed the equipment's maximum fluid line pressure. High fluid pressure remains in a spray system until it is relieved by shutting off the source of power and releasing the fluid pressure through the spray gun. 'If the high pressure stream of (coating) released from the spray gun comes in contact with the hand or any part of human body, it can penetrate the skin and cause physical harm. In the event an accidental penetration does occur, immediately go to the nearest hospital for medical attention. The high velocity flow of material through the spray tip may develop static electricity which can cause fire or an explosion if the unit is not grounded. The spray gun. must be grounded to an appropriate source to dissipate static electric. Always wear eye protection when handling the spray equipment. An accidental shot of spray material under high pressure directly into the eye can cause severe eye injuries. Catalyst must be kept in a cool place and out of direct sun light. Catalyst should be handled only with chemical resistant rubber gloves and soap and water should be used in the event you should come in direct skin contact with catalyst. A. Entering the Tank to Spray While the top man is preparing the spray system, the worker who will apply the lining material should enter the tank and be ready and waiting inside the tank to receive the spray line. Prior to applying the lining material, the inside of the tank shall be checked for LFL and an oxygen, and the readings documented on theconfined space permit. LEL and Oxygen readings shall be taken continuously after the initial reading. The explosion proof light should be covered with a clear plastic bag to protect it from over spray. Once the spray line is handed to the applicator, the large funnel should be placed in the access opening to allow adequate air ventilation while the lining is applied. I. Testina of the Linina A. Safety Considerations Vapor readings must be taken prior to performing any holiday testing to insure that the LEL is below 10% and continuously during testing. Ventilation must be maintained throughout testing operations. When a holiday test is being performed, a fire extinguisher should be present in the tank. Organic Vapor Masks must be worn during the testing procedures. Prior to holiday testing, test the entire tank interior with the combustible gas sniffer to assure a vapor free environment, and LEL below 10%. Warning: When Holiday testing a tank, proper vapor tests must be performed to insure that no gasoline vapor is in the tank. The tank must not contain any flammable materials during holiday testing such as acetone, trowel, or gasoline. Flammable materials can be ignited by the sparks of the holiday tester. CAUTION: Ventilation must be maintained throughout the testing procedures I. Line Tiahtness Testina A. Safety Considerations You must insure that the lines are free of flammable liquids prior to conducting a pressure test. Do not perform pressure tests on lines that are manifolded to operational tanks (tanks filled with product). If expandable or non threaded test plugs are used, do not exceed the recommended working pressure of the plug. 22 A. Line Testing Procedure: Lines should be tested to at least 70 psi but not more than 100 psi. Warning: If an expandable or non threaded type test plug is used, 70 psi may exceed it's . maximum working pressure. Never exceed the maximum working pressure of test plugs and, if necessary, do not test at 70 psi if the working pressure of the test plug will be exceeded. Always test within the working pressure limits of the test plugs. 'The line should hold pressure with no pressure loss for at least 30 minutes. If a pressure drop is noted; but appears to have stabitized, maintain the pressure for an additional 30 minutes. There should be no pressure drop on the line for at least 30 minutes after the air has stabilized. If a pressure drop is noted after stabilization and 30 minutes, the line may be leaking and may have to be repaired. I. Final Inspection of the Tank Prior to Closing After all the testing in the tank has been completed, a final check in the tank should be performed. The 'tape and covering around all pipes and pumps should be removed. If the interior has debris or dirt inside, the tank should be swept clean. Check the drop tube to insure that it can easily slide and be removed if necessary. I. Closing the Access Opening A. Safety Considerations An organic vapor mask and chemical resistant gloves must be used when handling trowel and base resin. Safety Glass should be used during the drilling operations. An air supplied respirator approved for sandblasting as well as hearing protection must be used for the blasting operation Ventilation shall be maintained on the tank while the lid is being ddlled and sandblasted LEL and Oxygen Readings shall be taken in the tank prior to conducting drilling and and sandblasting operations. A, Sandblasting Preparation The cover plate must be sandblasted to white metal on both sides prior to proceeding with the closing procedure. The area around the access opening on top of the tank must also be sandblasted to white metal to at least 6 inches beyond the perimeter of the overlapping lid. The sandblasting of the cover plate and the top of the tank should have been performed after you 23 have sandblasted the tank; however, if conditions such as water, moisture, dirt, etc. contaminated the blasted area, the tank and lid will have to be blasted again. Ventilation shall be maintained on the tank during the sandblasting operation. An approved air supplied sandblast helmet and hearing protection shall be worn during the sandblasting process. LEL and oxygen readings of tank interior shall be taken prior to sandblasting the tank opening to insure that the LEL below 10%. Drilling of the lid / When ddlling the lid, venitlation shall be maintined on the tank dudng the ddlling process. Eye protection shall be worn during the drilling. I. Air Testin(~ the Cover Plate A. Safety Considerations Never apply more than 5 psi to a tank. Too much air can rupture the tank Do not apply air pressure to tanks that are manifolded to operational tanks (tanks filled with product) or to tanks that contain product A. Procedure For Testing Cover Plate ]. Air Test To air pressure test the tank and the coverplate, start by capping or plugging the vent tine. Do not cap a vent line that may be attached to another tank. Tanks must be isolated form operational tanks prior to performing air tests. If the tank has a submerge pump system, the brass screw on top of the submerge pump can be screwed in, closing the product line going to the dispenser on the island. The shear valves should be turned off (so that the product is off). Leaks can happen at the dispenser if the shear valves are not set to the off position. Slowly allow air into the tank after the system has been sealed. Do not place more than 5 psi in the tank I. Final Site Clean Up After you have comPlete your work, make sure that you sweep and clean the site Inspect the site for sandblast dust. It may sometimes be necessary to wash dispensers and windows with a hose to remove sandblast dust. The site should be just as clean or cleaner than when you had first arrived after your clean-up is complete. Sweep the work are so the station will be left in better condition than it was before your arrival. 24 All tag/lock out devises should be detached and power reactivated in the presence of the station manager. All equipment should be pmpedy stored and secured in your trailer. All hazardous materials should be pmpedy contained, labeled and manifested for disposal and any necessary Bills of Lading should be comPleted. All notices should be removed from the job site and placards should be propedy displayed on the dg before departing the job site. 2,5 PERSONNEL: PROJECT MANAGER: ROSS SESSIONS - Ensures the Work Plan is completed on schedule. - Briefs the field teams on their specific assignments. - Participates in the preparation and execution of the Site Safety man.

HAZARDOUS POLYMERIZATION: May occur if exposed to heat sot, rccs or prolonged storage above 38°C (100°F') SECTION V - HEALTII HAZARD DATA PRIMARY ROUTES OF ENTRY: Inhalatiou, skin contact HEALTH HAZARDS; (Including acute and chronic effects and symptoms of overexposure) (Healtl~ ha_:,ards are given for sryrenc) ACUTE: Inhalation; Upper respiratory tract irritation. Possible central nervous systmn effects include headache, drowsiness, di2-Aness, loss of coordination, impaired judgment, nausea, gastric upset al~d xveakness. Effects mimic drunkenness and th cllects will be increased by consumption of alcohol or mood altering drugs. Exposure to dust froth fabrication of finished (cured) parts may result in temporary discomlort or irritation of the upper resl~imtory tract. Skin Contact: May result in skin irritation. Styrene is considered to bc a primary skin irritant. Eye Contaet~ May catts¢ r~vcre irritation, redness, tearing nod blurred vision. Ingestion: May cause mouth, throat and gastrointestinal irritation, nausea, vomiting and diarrhea. Aspiratio~ material into the lungs can cause chemical pneumonitis which can b¢ fatal. CI-LP, Olq'IC: Prolonged exposure may result in nausea, loss of appetite, general weakness, cha.tges in blood chemistu and skin contact may result in dermatitis, nmrked by rough, dry or crocked skin. Prolonged or rcpeated ey~ exposure to the vapor may caus irritation to the liuing of the eyelids. In habomtory animals, chronic exposure at higl~ concentrations 1~ been found to cause liver abnormalities, kiduey damage and hmg damage, la addition, preliminaD, results of inlxalation studies indicate tlmt laboratony ra~s exposed to :gOO rmn styrenc via ii, halation showed cvidence or' hearing loss. Relevance to humans remain.s uncle,ar. CA~CINOGENICITY: HfkZARDOUSINGREDIENTS: Listed By: ACGIH IARC NIP OSHA Styrene No Yes No No IARC: In, March, 1987, the International Agency for R~se~'~rch on Cancer (IARC) reclassified styxene ,'ts possibly carcin0geni to humans (Group 2B) duc to 'inadequate evidence in humans~, 'Limitccl evidence in animals" and "other relevant data", Previously, styrene was classified as a Group 3 compound, not classifiable as to carcinogenicRy in hu.mns. Thc IARC working group determined that the weight of da[~ on genetic and related cffcc~s together xvim ti,,: ,"onsidcradon that styrene is metabolized in humans and animals styrene oxide, for which there is sufficient evidence of carcinogenicity iix exporimentat animals which has been classified by IARC as probably carcinogenic to humans (Group 2A), was sufficient reason to recommend thc change in classification. Medical Conditions Al~.eravalcd by Expo.sure: Persons with a liistory of chronic respiratory disease, skits disease, or central or peripheral nervous system disorders ,my at increased risk form exposure to tiffs product. SECTION VI - E1VIPLOYEE PROTECTION VENTILATION: Provide adcquatc general and/or local exhaust ventilation lo maintain exposures below PEL's and TLV's. RESPIRATORY PROTECTION - If irritation occurs or il' thc PEL or TLV is exceeded, use a NOISI-b'MSHA approved air purifying respirator with organic vapor ~rtridges or canisters or supplied air respirator.
