What is the correct procedure for an LP (liquid propane) forklift when a fuel leak is detected?
Answer: Shut off the fuel valve, move the forklift outdoors, and report to maintenance
A propane leak must be addressed immediately by shutting off the fuel valve, moving the forklift to a safe outdoor area, and reporting to maintenance to prevent fire or explosion.
What is the minimum safe distance from a forklift battery charging station that open flames or sparks should be maintained?
Answer: At least 15 feet or per facility policy
Hydrogen gas from charging batteries can travel significant distances, so open flames or spark-producing equipment must be kept at a safe distance — typically at least 15 feet — from charging areas.
When should water be added to a lead-acid forklift battery?
Answer: After a full charge cycle is complete
Water should be added after a full charge because charging causes the electrolyte to expand; adding water before charging can cause overflow and acid spills.
What does it indicate when a forklift battery consistently requires more water than usual between charges?
Answer: Overcharging or a malfunctioning charger may be damaging the battery
Excessive water consumption in a battery is a sign of overcharging, which causes excessive gassing and electrolyte loss, and indicates the charger settings or battery should be inspected.
How should an LP cylinder be stored when not in use on a forklift?
Answer: Upright in a well-ventilated area away from heat sources and ignition
LP cylinders must be stored upright in well-ventilated areas away from heat and ignition sources to prevent pressure buildup, leaks, and fire hazards.
What is the maximum state of discharge recommended before recharging an electric forklift battery to extend battery life?
Answer: 20% remaining capacity (80% discharged)
Most lead-acid industrial batteries should be recharged when 80% discharged (20% remaining) to avoid deep discharge damage and maximize battery cycle life.
What is the correct way to change an electric forklift battery when using a lifting device?
Answer: Use the proper battery changing equipment with the forklift on a level surface and brakes applied
Battery changes must be performed on a level surface with parking brakes applied using approved battery-handling equipment to prevent injury from the heavy battery weight and acid spills.
