Which action is essential to ensure safety before refueling a propane-powered forklift?

• A. Leave the engine running and close nothing.
• B. Ignore the valve if propane.
• 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. Open all hatches and increase ventilation.

Answer: (C)

Before refueling a propane forklift, the priority is to prevent ignition and control any fuel release. Turning off the engine removes potential ignition sources like hot exhaust or energized electrical components. Closing the fuel valve on the propane tank stops any further gas from flowing, reducing the chance of vapors building up during the fill. Venting the area helps disperse any propane that may have escaped, lowering the risk of a flammable vapor cloud. Removing the key ensures the forklift cannot be started accidentally while refueling. Keeping ignition sources away—no flames, sparks, or smoking nearby—is essential because propane vapors can ignite easily if an ignition source is present. The other options fail to address both stopping fuel flow and eliminating ignition risk, so they’re not safe choices.
