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.
8. Confirm that products are being loaded into the correct tank truck compartment(s), that the meter is properly set for the compartment size and that no mixing of products occurs.
9. When starting product flow, check all hoses and connections 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.
