CPR Equipment Operation & Site Safety 2 — Questions and Answers
Question 1: When operating a scissor lift on a priority restoration site, what is the maximum allowable side slope before operation must stop?
- 3 degrees
- 5 degrees (Correct answer)
- 7 degrees
- 10 degrees
Correct answer: 5 degrees
Most scissor lifts are rated for a maximum 5-degree side slope; exceeding this creates tip-over risk on uneven disaster sites.
Question 2: Which document must an equipment operator review BEFORE using a piece of restoration equipment for the first time on a job site?
- The project schedule
- The manufacturer's operator manual (Correct answer)
- The insurance certificate
- The client's scope of work
Correct answer: The manufacturer's operator manual
The manufacturer's operator manual contains rated capacities, safety warnings, and operating procedures specific to that machine.
Question 3: A crew member notices hydraulic fluid leaking from an excavator arm. What is the correct immediate action?
- Continue operating at reduced speed
- Notify the foreman but keep working
- Tag out and remove the machine from service (Correct answer)
- Apply hydraulic sealant and monitor
Correct answer: Tag out and remove the machine from service
A hydraulic leak constitutes a mechanical defect requiring lockout/tagout and removal from service until properly repaired.
Question 4: What is the primary purpose of a pre-task safety plan (PTP) completed before each shift on a CPR site?
- Document labor hours for billing
- Identify site-specific hazards and controls for the day's tasks (Correct answer)
- Satisfy insurance documentation requirements only
- Assign overtime responsibilities
Correct answer: Identify site-specific hazards and controls for the day's tasks
A pre-task plan identifies that day's specific hazards, assigns controls, and ensures all crew members are briefed before work begins.
Question 5: When using a chainsaw for debris removal, the operator's left hand should maintain which grip position?
- Wrap-around grip on the front handle bar (Correct answer)
- Open-palm contact with the rear handle
- Thumb-only grip on the chain guard
- Both hands on the rear handle only
Correct answer: Wrap-around grip on the front handle bar
A wrap-around grip on the front handlebar provides maximum control and activates the chain brake should kickback occur.
Question 6: On a restoration site with active utilities, equipment operators must maintain a minimum clearance of how many feet from overhead power lines rated up to 50 kV?
- 5 feet
- 10 feet (Correct answer)
- 20 feet
- 50 feet
Correct answer: 10 feet
OSHA 1926.1408 requires a minimum 10-foot clearance from power lines up to 50 kV for equipment operation.
Question 7: Which fall protection method is required when workers are on a flat roof at a height of 8 feet during a restoration project?
- No protection required below 10 feet on flat surfaces
- Warning line system only
- Personal fall arrest system, guardrail, or safety net (Correct answer)
- Verbal spotter only
Correct answer: Personal fall arrest system, guardrail, or safety net
OSHA requires fall protection at 6 feet or more in construction; acceptable methods include guardrails, personal fall arrest systems, or safety nets.
