Practice 2
2 hours
Learning Objectives
- •Apply ground assessment and stability principles to realistic setup scenarios
- •Apply pre-use inspection knowledge to identify removal-from-service conditions
- •Integrate regulations, equipment, and operation knowledge across mixed scenarios
- •Self-assess exam readiness and identify weak topic areas for further study
Topics Covered
- •Review: ground assessment, soil bearing, slope limits, and underground voids
- •Review: pre-use inspection, function testing, and removal-from-service conditions
- •Review: travel with the platform raised and overhead/obstruction hazards
- •Review: tip-over causes and how stability is maintained for boom and scissor lifts
- •Review: documentation, defect reporting, and tag-out
- •Comprehensive mixed-topic practice questions in exam format

Self-Check Questions
Question 1: A boom lift must be set up partly over a recently backfilled utility trench. The safest action is to:
- A. Set up as planned — backfill is always compacted
- B. Reposition onto firm, undisturbed ground or properly support and assess the area before setup(correct)
- C. Set up but keep the platform under 10 feet
- D. Drive across it quickly to avoid sinking
Show Explanation
Explanation:
Backfilled trenches are often uncompacted and can let a wheel or outrigger sink. Relocate to undisturbed ground, or properly assess and support the area — never assume backfill will hold.
Question 2: During a pre-use inspection you find the platform gate latch is broken and will not stay closed. You should:
- A. Tie the gate shut with wire and operate
- B. Tag the machine out of service until the gate is repaired(correct)
- C. Operate but keep the platform low
- D. Operate only with two workers in the basket
Show Explanation
Explanation:
The gate is part of the guardrail system. A gate that will not latch leaves an open fall hazard — the machine must be tagged out and repaired before use.
Question 3: Which combination of conditions presents the highest tip-over risk for a boom lift?
- A. Platform stowed, machine on level pavement
- B. Boom extended horizontally, chassis out of level, with wind on the platform(correct)
- C. Platform raised straight up on level, firm ground in calm air
- D. Driving slowly with the boom cradled
Show Explanation
Explanation:
Horizontal boom extension moves the load away from the chassis, an out-of-level chassis shifts the center of gravity, and wind adds a side force. Stacking these conditions can push the machine past its stability limits.
Question 4: A MEWP emergency stop button at the platform does not work during the pre-use function test. What is the correct response?
- A. Use the machine anyway since the controls still work
- B. Remove the machine from service and tag it until the emergency stop is repaired(correct)
- C. Test it again at full height
- D. Disconnect the battery to reset it and continue
Show Explanation
Explanation:
An inoperative emergency stop is a removal-from-service condition. Safety devices must function before the machine is used — tag it out and have it repaired by qualified personnel.
Question 5: An operator finishes the shift and parks the MEWP. To leave it safe, the operator should:
- A. Leave the platform raised for the next crew
- B. Fully lower the platform, set the brakes, shut down, secure the controls, and report any defects(correct)
- C. Leave the keys in and the engine running
- D. Park it on a slope to save flat space
Show Explanation
Explanation:
Proper shutdown means the platform is lowered and stowed, brakes set, machine off and secured, parked on firm level ground, and any defects reported so the next operator is not surprised.
Question 6: Travel with the platform raised is permitted on a MEWP:
- A. Always, as long as the operator is careful
- B. Never, under any circumstances
- C. Only within the manufacturer stated limits, on firm and level ground, with a clear path(correct)
- D. Only on public roads
Show Explanation
Explanation:
Some MEWPs allow limited elevated travel, but only within the manufacturer limits and on firm, level ground with a clear route. Raised travel over uneven ground or near drop-offs is a major tip-over cause.
Question 7: On the exam you find you keep missing questions about MEWP classification. The best use of your remaining study time is to:
- A. Skip that topic — it is unlikely to appear again
- B. Focus your review on the A92 Group A/B and Type 1/2/3 system until you can apply it confidently(correct)
- C. Only re-read topics you already know well
- D. Memorize the answers without understanding why
Show Explanation
Explanation:
Targeted review of weak areas is the most efficient way to raise your score. Understanding the A92 classification system — not just memorizing it — lets you answer scenario questions you have not seen before.
