What is the primary purpose of floor load capacity markings in a warehouse?
Answer: To prevent floor structural failure from overloading by forklifts and stacked materials
Floor load ratings define the maximum weight per square foot the structure can support; exceeding them risks collapse.
A forklift operator smells propane near the engine compartment of an LP-powered truck. What is the correct response?
Answer: Shut off the fuel valve, stop the engine, and report the leak immediately
Propane is flammable and heavier than air; the operator must shut off the fuel, stop the engine, and report the hazard before any ignition source is introduced.
Which action best reduces the risk of a forklift striking a pedestrian at a blind intersection?
Answer: Installing convex mirrors and requiring operators to sound the horn before entering
Convex mirrors provide visibility around corners, and sounding the horn warns pedestrians before a forklift enters a blind intersection.
In risk management terminology, what is a 'residual risk'?
Answer: The risk that remains after all feasible controls have been implemented
Residual risk is what remains after controls are in place; it must be accepted, monitored, or reduced further.
Which environmental condition most increases the risk of a forklift fire during cold-storage operations?
Answer: Condensation accumulating on electrical components as the truck warms up
Condensation on electrical components when a cold-storage forklift enters a warm area can cause short circuits that may ignite a fire.
What is the most reliable indicator that a racking system in a warehouse poses an imminent collapse hazard?
Answer: Upright columns are bent, cracked, or missing safety pins
Structural damage to rack uprights — bending, cracking, or missing safety pins — directly compromises load-bearing capacity and signals imminent failure risk.
Why is it hazardous to operate a diesel forklift in an enclosed building without adequate ventilation?
Answer: Carbon monoxide and particulate emissions can reach dangerous concentrations indoors
Diesel combustion produces carbon monoxide, nitrogen oxides, and fine particulates that accumulate to toxic levels without sufficient fresh-air ventilation.
