In refueling a propane-powered forklift, which steps constitute the correct shutdown procedure before fueling?

• A. Turn off the engine, remove the key, vent the area, and ensure there are no ignition sources nearby.
• B. Turn on the engine to warm the system, leave the area unvented, and ignore ignition sources.
• C. Turn off the engine, close the fuel valve if using propane, vent the area, remove the key, and ensure there are no ignition sources nearby.
• D. Shut down by simply closing the fuel valve and leaving the area.

Answer: (C)

The safety goal is to eliminate ignition sources and disperse any propane vapors before handling fuel. Start by turning off the engine to stop any sparks or hot surfaces from creating an ignition source. Close the propane fuel valve to stop gas flow and reduce the risk of leakage during fueling. Vent the area to let any vapors escape, since propane is heavier than air and can pool in low spots. Remove the key to prevent the forklift from being restarted accidentally, and confirm there are no ignition sources nearby—no flames, sparks, smoking, or exposed electrical equipment. Following these steps together minimizes the chance of ignition during fueling.
