MHC Material Handling Equipment Operation 3 — Questions and Answers
Question 1: An order selector (order picker) operator must wear a fall arrest harness because:
- The operator platform elevates with the forks, creating fall risk (Correct answer)
- OSHA requires harnesses in all warehouse environments
- The machine has no seatbelt
- Elevated platforms always exceed 4 feet
Correct answer: The operator platform elevates with the forks, creating fall risk
Order picker operators ride the elevated platform and are exposed to fall hazards, requiring a full-body harness attached to the anchor point on the machine.
Question 2: What is the primary purpose of anti-slip plates or cross-hatching on forklift fork surfaces?
- To increase friction and prevent loads from sliding off the forks (Correct answer)
- To reduce fork weight for higher capacity
- To indicate fork wear limits
- To help the operator judge fork width
Correct answer: To increase friction and prevent loads from sliding off the forks
Anti-slip texturing on forks increases friction between the load and fork surface, helping prevent loads from sliding during travel.
Question 3: During a pre-operation inspection, an operator finds the forklift's horn is not working. The operator should:
- Tag the unit out of service and report it before operating (Correct answer)
- Operate carefully and use hand signals instead
- Fix the horn themselves before the shift
- Operate the forklift since the horn is non-critical
Correct answer: Tag the unit out of service and report it before operating
A non-functional horn is a safety defect; the operator must tag the unit out of service and notify a supervisor before operation.
Question 4: When using a walkie stacker to stack pallets, the operator must ensure the stacking surface is:
- Level, firm, and capable of supporting the combined load weight (Correct answer)
- Slightly inclined to allow runoff of water
- At least 10 feet wide for maneuvering
- Marked with yellow safety tape
Correct answer: Level, firm, and capable of supporting the combined load weight
The stacking surface must be level, stable, and have adequate floor load capacity to safely support stacked pallets and the equipment.
Question 5: A double-reach truck differs from a standard reach truck because it:
- Can extend its forks two pallet positions deep into racking (Correct answer)
- Has two sets of forks for handling two pallets at once
- Operates at twice the speed of a standard reach truck
- Requires two operators to function safely
Correct answer: Can extend its forks two pallet positions deep into racking
A double-deep reach truck has extended pantograph arms that allow it to place or retrieve pallets two positions deep in double-deep racking systems.
Question 6: What action should a forklift operator take when approaching a blind corner or intersection in a warehouse?
- Slow down, sound the horn, and proceed cautiously (Correct answer)
- Speed up to clear the intersection quickly
- Flash the overhead light repeatedly
- Stop completely and wait 30 seconds before proceeding
Correct answer: Slow down, sound the horn, and proceed cautiously
At blind corners, operators must reduce speed, sound the horn to warn pedestrians, and proceed only when it is safe to do so.
Question 7: Which of the following best describes 'load creep' on a hydraulic pallet jack?
- Slow lowering of the forks due to internal hydraulic fluid leak (Correct answer)
- The load sliding sideways on the forks during travel
- Gradual forward movement of the machine when parked
- Overloading the jack beyond its rated capacity
Correct answer: Slow lowering of the forks due to internal hydraulic fluid leak
Load creep refers to the slow, unintended lowering of forks caused by internal hydraulic seal wear or leakage, which is a remove-from-service condition.
