Forklift certification Certification Forklift certification Refueling and Recharging Procedures 2 — Questions and Answers
Question 1: Before refueling a propane (LPG) forklift, what should the operator do first?
- Turn off the engine and remove the key (Correct answer)
- Leave the engine idling to keep pressure stable
- Disconnect the battery
- Open all cab windows only
Correct answer: Turn off the engine and remove the key
The engine must be shut off and the ignition key removed before any fuel connection is handled.
Question 2: Where should LPG forklift refueling ideally take place?
- In an enclosed storage room
- In a well-ventilated outdoor or open area (Correct answer)
- Next to the battery charging station
- In a sealed maintenance bay
Correct answer: In a well-ventilated outdoor or open area
Propane refueling should occur outdoors or in a well-ventilated area to prevent gas accumulation.
Question 3: What personal protective equipment is required when changing an LPG cylinder?
- Nothing special is needed
- Insulated gloves and eye protection (Correct answer)
- Only a hard hat
- A respirator only
Correct answer: Insulated gloves and eye protection
Gloves protect against cold-burn from escaping liquid propane and eye protection guards against splash.
Question 4: After connecting a new propane cylinder, what should you check before starting?
- Tire pressure
- The connection for leaks using a soapy solution or sniff test (Correct answer)
- The horn
- The seat adjustment
Correct answer: The connection for leaks using a soapy solution or sniff test
Checking the fitting for leaks prevents a fire or explosion hazard before operation.
Question 5: Which position should the LPG cylinder relief valve point when mounted?
- Downward toward the ground
- Upward into the vapor space (Correct answer)
- Sideways toward the operator
- It does not matter
Correct answer: Upward into the vapor space
The pressure relief valve must sit in the vapor space (usually indicated by an alignment pin) to vent gas, not liquid.
Question 6: If you smell propane while refueling, what is the correct action?
- Continue quickly to finish
- Close the service valve, stop, and ventilate the area (Correct answer)
- Start the engine to burn it off
- Ignore it if it is faint
Correct answer: Close the service valve, stop, and ventilate the area
Shutting the valve and ventilating stops the leak and disperses the gas safely.
Question 7: Why must the service valve on the LPG cylinder be fully closed before disconnecting?
- To keep the cylinder clean
- To prevent liquid propane from spraying out (Correct answer)
- To save fuel weight
- To reset the gauge
Correct answer: To prevent liquid propane from spraying out
A closed service valve stops pressurized liquid propane from escaping when the coupling is removed.
