3. Walk around the tank truck and conduct a visual inspection for hot or deflated tires, defective brakes, damaged springs, etc. Listen for air leaks in brake sys- tem, ensure product compartment identification dial (if so equipped), is set, and proper DOT placards are in place. This should be done either before or after pulling under the rack. 2.3 Loading Drivers (loaders) should identify the location of the closest loading rack emergency shutdown control, por- table fire extinguishers and, where provided, the fire blanket and the load rack fire suppression system. The driver (loader) should also know the location of the mechanical product flow shut-off valve and how to operate it if the main flow-control valve malfunctions. Tank trucks must not be left unattended at the load rack. Refer to terminal or company load rack procedures for Personal Protective Equipment (PPE) requirements while loading tank trucks.
1. Make sure that all tank truck valves are closed. 2. Connect the overfill protection plug/cord to the tank truck. Wait for green (or permission) light to illuminate before proceeding. 3. Check the vapor recovery hose for trapped liquid or other defects that would impede the free flow of vapors to the rack system. Connect the vapor recovery hose to the trailer. Completely close both camlock ears on the hose connector. A vapor-tight connection is required. 4. Be sure the brake interlock system is working. 5. Connect the bottom loading arm(s). 6. Open internal valves for the compartment(s) being loaded. 7. Set the number of gallons (liters) to be loaded on the meter set stop. CAUTION: Under no circumstances should the overfill sensors be used as a meter stop. The pump’s gradual slow down is controlled by the meter settings and use of the overfill sensors or other methods of shutting down product flow can result in a sudden shock to the product pumps, resulting in possible damage to pumps and piping.
9. When starting product flow, check all hoses and con- nections for leaks or drips. Stop loading immediately if leaks or drips occur. U.S. Environmental Protection Agency (EPA) regulations require the tank truck to be vapor-tight while loading. If vapors are determined to be escaping during the loading process, stop immediately, notify terminal personnel and your dispatcher/supervisor. 10. While vehicle is being loaded, driver (loader) must remain near the set-stop or, where provided, hold the dead man switch. Maintain observation of the loading at all times. Under no circumstances is the dead man switch to be strapped down or by-passed. 11. Precautions: • Do not clean or make repairs to the vehicle while in the loading position. • Shut truck tractor doors to prevent dome light from being activated. • Only authorized personnel should be at the loading position.
• In the event of a fire, activate the load rack fire suppression system, leave the area and alert other drivers. • If the previous shutdown steps do not stop the flow, the driver should activate the mechanical shut-off valve, as described in Section 2.3, “Loading”. 15. Once a tank truck compartment is filled, first close all internal valves, then disconnect the loading arm and secure the unloading coupler. Verify that proper product and quantities were loaded. 16. Repeat process for each tank truck compartment being filled. (Section 2.3, “Loading”, Steps 5- 15) 17. When all loading is complete, disconnect the vapor recovery hose. 18. Disconnect the overfill protection plug/cord and replace the protective cap or, if used, disconnect the bonding cable. 19. Look down the sides of the truck for obstructions and ensure personnel have vacated the area. Make sure all loading equipment is returned to its proper position. Check the loading area and adjacent lanes for problems before leaving.
