Practice 1
2 hours
Learning Objectives
- •Recall the Massachusetts licensing rules: age, exam score, license duration, fees, and retest waiting period
- •Distinguish boom lifts from scissor lifts in terms of design, MEWP group, and fall-protection requirements
- •Apply the ANSI/SAIA A92 standards and classification system to operating scenarios
- •Demonstrate understanding of power-line clearance and basic stability principles
Topics Covered
- •Review: MGL Chapter 146 and 230 CMR 6.00 licensing and operating rules
- •Review: the ANSI/SAIA A92.20 / A92.22 / A92.24 standards and the Group / Type classification system
- •Review: boom lift vs. scissor lift design and fall-protection differences
- •Review: OSHA 29 CFR 1926.453 fall protection and power-line clearance
- •Review: hydraulics, controls, and the upper/lower control override relationship
- •Mixed-topic practice questions in exam format

Self-Check Questions
Question 1: You fail the hoisting exam. How long must you wait to retake it, and what is the passing score you need?
- A. 30 days; 65%
- B. 60 days; 70%(correct)
- C. 90 days; 75%
- D. No wait; 70%
Show Explanation
Explanation:
The retest waiting period is 60 days and the passing score is 70%. Both numbers are common exam questions — commit them to memory.
Question 2: A telescopic boom lift and an electric slab scissor lift are on the same job. Which statement about fall protection is correct?
- A. Both require only guardrails
- B. Both require a personal fall arrest harness at all times
- C. The boom lift requires a harness to the anchor point; the scissor lift relies on its intact guardrail system(correct)
- D. Neither requires any fall protection below 30 feet
Show Explanation
Explanation:
OSHA treats boom lifts as aerial lifts (harness required) and scissor lifts as mobile scaffolds (intact guardrails are the primary protection). Knowing which rule applies to which machine is essential.
Question 3: Which ANSI/SAIA A92 standard would a training provider follow when building a MEWP operator course?
- A. A92.20
- B. A92.22
- C. A92.24(correct)
- D. A92.6
Show Explanation
Explanation:
A92.24 is the training standard. A92.20 governs design/build and A92.22 governs safe use — design, use, train.
Question 4: An operator wants to belt off to a building beam for "extra security" while in a boom lift basket. This is:
- A. A good practice OSHA encourages
- B. Prohibited by OSHA — the lanyard must attach to the manufacturer basket anchor point(correct)
- C. Allowed only above 50 feet
- D. Allowed if the beam is painted
Show Explanation
Explanation:
OSHA 1926.453 prohibits belting off to an adjacent structure. If the lift tips or moves, a worker tied to an external point can be pulled out of the basket.
Question 5: On a MEWP, the ground (lower) controls are primarily there to:
- A. Let a supervisor race the operator
- B. Allow rescue and emergency lowering by overriding the platform controls(correct)
- C. Increase the platform rated capacity
- D. Charge the battery
Show Explanation
Explanation:
Ground controls can override the upper controls so someone on the ground can lower an incapacitated operator or a stuck platform. The ground station must always be kept clear and accessible.
Question 6: Most scissor lifts are Group A and most boom lifts are Group B. The key difference is that a Group B platform:
- A. Is always battery powered
- B. Can move beyond the tipping lines of the chassis(correct)
- C. Cannot be used outdoors
- D. Has no rated capacity
Show Explanation
Explanation:
Group B platforms can extend beyond the tipping lines, which is normal for booms. That is why boom lift stability depends so heavily on level ground, avoiding side loads, and respecting the capacity placard.
Question 7: You must work near a power line of unknown voltage. The correct approach is to:
- A. Get as close as needed and work quickly
- B. Maintain at least 10 feet of clearance, treat the line as energized, and increase the distance for higher voltage(correct)
- C. Touch the line briefly to test if it is live
- D. Rely on rubber tires to insulate the machine
Show Explanation
Explanation:
OSHA requires a minimum 10-foot approach distance for lines up to 50 kV, with more clearance for higher voltages. Always assume a line is energized unless it has been confirmed de-energized and grounded.
