STANDARD OPERATING PROCEDURE FOR SOLVENT TANK TRUCK LOADING Steps Key Points i. Close derail and set up blue flag signs. 1. Tank truck loading is performed over a rail car track, so rack must be secure from oncoming rail cars. 2, Spot truck at appropriate loading station and lower access ramp zo truck. 3. Examine PPG bill of lading, car- 3- This must be done to make sure customer rier bill of lading, and copy of gets correct product, and to comply with customer order for product to be certain customer or sales office requests loaded, quantities of product, and such as: any special loading or shipping instructions. a. Sending certificate of analysis to customer. b. Meeting special product specifications. c. Sealing truck for shipment. d. Amounts and size of hose required. e. Drum nozzle, if required. 4. Check the Motor Carrier number (MC No.) of the tank, and the test date(s) stenciled on the front of the trailer. Record MC No. and test dates on PPG Bill of Lading. 4. The MC No. signifies certain design features of the tank, such as valving, safety relief devices, and materials of construction. Solvents can only be loaded in certain type tanks (see chart - Tank Trailer MC Type Number). 5. Check the interior of the trailer compartment( s) using the high in tensity light source on the rack. 5. Any trash, moisture, or chemical(s) which would contaminate or react with solvents must be removed from the trailer before it is loaded. 6. Check the piping and valving on the tank. 6. The tank must have, for each compartment, a primary and secondary outlet valve in the discharge piping, and a dust cap for each discharge outlet. The primary valve is commonly called the internal valve, and is located at the com partment discharge opening. The secondary valve is at the end of the discharge piping for each compartment. SL 091376 7. Check the discharge valves for operation. 7A. For the following products: Trichlor ~ all grades. Perchlor - all grades. Trichloroethane - all grades. Primary valves must operate but do not have to be leak tight. 7B. For the following products: Ethylene Dichloride Vinylidene Chloride Primary valves must operate and must not leak through. 7C. Secondary valves must operate and must not leak through, regardless of product loaded. 7D. The operation of the valves is the driver's responsibility. You merely have to wit ness the operation of the valves to make certain they operate. 8. If required, check the trailer for 8. For the following products: safety relief devices and fusible Ethylene Dichloride disc caps. Vinylidene Chloride The trailer must have at the top of each Note: See Addendum No. 1 compartment, at least one safety relief device and one fusible disc cap. 9. For vinylidene chloride shipments 9. Trailer must be able to hold a nitrogen pad only. for vinylidene chloride shipments. Trailer must not leak. Check all fittings, valves, Check trailer for leaks. If trailer gaskets for leaks prior to loading. Use is suitable to load, insert a purging nitrogen when pressure checking and purging lance through open hatch and purge trailers. trailer about five minutes to clear air from trailer. Remove lance after purging and secure hatch cover. 10. Determine the quantity of product 10. Weight limitations on highways in various to be loaded from applicable states differ. Use current weight limit in tables or charts. formation to determine load. Foreman will provide information regarding any blends that must be loaded. 11. If product is available in ship- 11. Always leave recirculation valve to tank ping tank, open appropriate open slightly to protect pump seal when valves to loading pump and line up discharge valve is closed on rack. to rack and start pump. SL 091377 - 3- 11, If product must come from operating unit, call the operator in unit and request transfer of product needed. 12. For vinylidene chloride and ethylene dichloride shipments only. Connect grounding leads to trailer 12. prior to loading product. Connect one lead from rack to truck, and one lead from the loading line, upstream of the discharge valve, to the trailer. Grounding must be done in order to prevent static ele:tricity buildup while loading flammable products. 13. For solvents and ethylene dichloride shipments. Load trailer with product through 13. opened hatch. Flush several gallons of product through discharge piping of truck to remove hidden trash or moisture that may be present. After loading, shut down loading pump. Spills must be avoided. Flush must be directed to flush collection system. Use meter to load truck, if operational, other wise use outage gauge. Use stainless steel loading pipe when loading product. 14. For, vinylidene chloride shipments only. Connect loading hose to discharge 14. piping of truck. Connect vent hose between vent control system and vent piping atop trailer. Open vent valves on control system and on trailer. Open discharge valves on trailer. Open loading line valve and load trailer with product using in line meter. Personnel exposure to and releases to the environment of liquid and vapor vinylidene chloride must be avoided. Vent must go to control system. After trailer is loaded, clear loading line into truck using nitrogen. Shut down loading pump. Clear vent line into trailer using nitrogen until pressure inside trailer is 12 - 15 PSIG. Disconconnect vent line from trailer. Check trailer again for leaks. All leaks must be stopped before shipment is made. Trailer must be able to hold nitrogen pad to avoid oxygen intrusion into trailer and contacting product. SL 091378 -4- 15. Sample product in glass container. 15. Properly identify sample and de liver to main laboratory for analy sis . Every shipment of solvents and ethylene dichloride must be sampled. Sample must' be analyzed and cleared by main laboratory before shipment can be made. For Solvents - Use one-half gallon glass bottle. For Ethylene Dichloride - Use one gallon amber stained bottle. 15a. Vinylidene chloride shipments will be sampled only under certain circumstances. Check with shipping foreman before sampling 16. Attach product identification tag 16. It is PPG policy that this identification to hatch cover and discharge line be made before shipment is made. of every loaded compartment of the truck. 17. Complete paperwork in office as follows: 1. Sign bills of lading and car riers demurrage ticket, if necessary. 1. DOT regulations require signing of bill of lading. 2. Identify on PPG bill of lading the content of each compart ment of a multi-compartment trailer and have driver sign to acknowledge same. 2. Identify loaded as well as empty com partments. Driver must sign before he leaves plant. 3. Provide driver with placards, if truck must be placarded. It is driver's responsibility to placard truck. 3. Placard product shipments as follows: Ethylene Dichloride - UN 1184 Vinylidene chloride - UN 1303 Trichloroethylene - UN 1710 4. Provide driver with transpor tation safety data card for each product loaded on truck. 4. It is a PPG policy that this be done, and so states on the PPG bill of lading 5. Complete shipping department record forms as required. 18. Raise access ramp to truck, disconnect grounding leads from truck, clear personnel from area, and release truck to weigh and depart plant.
