CPR Equipment Operation & Site Safety 3 — Questions and Answers
Question 1: A forklift on a restoration site is rated for 5,000 lbs at a 24-inch load center. If the actual load center moves to 36 inches, the effective capacity:
- Remains 5,000 lbs
- Increases proportionally
- Decreases significantly (Correct answer)
- Doubles due to leverage
Correct answer: Decreases significantly
Moving the load center farther from the forks reduces a forklift's effective lifting capacity because of increased leverage on the tipping point.
Question 2: Which color of safety tag is universally used to indicate a piece of equipment is OUT OF SERVICE and must not be operated?
- Yellow
- Green
- Red (Correct answer)
- Blue
Correct answer: Red
Red tags indicate danger — equipment is defective or locked out and must not be used until the tag is removed by authorized personnel.
Question 3: During generator operation at a restoration site, where should the generator be positioned relative to occupied structures?
- Inside the structure for security
- Downwind and at least 20 feet from any opening (Correct answer)
- Directly adjacent to the main electrical panel
- Upwind to allow natural ventilation
Correct answer: Downwind and at least 20 feet from any opening
Generators must be placed downwind and at least 20 feet from openings to prevent carbon monoxide accumulation inside occupied spaces.
Question 4: What is the correct procedure when a restoration crew discovers an unmarked container of unknown liquid on a debris removal site?
- Dispose of it in the dumpster immediately
- Open it to smell the contents for identification
- Treat it as hazardous, isolate the area, and notify the supervisor (Correct answer)
- Move it to a collection pile with other debris
Correct answer: Treat it as hazardous, isolate the area, and notify the supervisor
Unknown containers must be treated as potentially hazardous materials; the area should be isolated and a supervisor or HazMat coordinator notified.
Question 5: Which inspection must be performed on a pump truck's hose system before each use on a water damage restoration project?
- Flow rate calibration test
- Visual inspection for cracks, kinks, and secure couplings (Correct answer)
- Electrical continuity test of the hose lining
- Pressure test to maximum rated PSI
Correct answer: Visual inspection for cracks, kinks, and secure couplings
A visual inspection before each use checks for hose integrity, kinks that restrict flow, and secure coupler connections to prevent failures during operation.
Question 6: When setting up a negative air pressure machine in a contaminated restoration zone, ductwork must exhaust:
- Into an adjacent room to filter air on site
- Directly outdoors away from re-entry points (Correct answer)
- Into the HVAC return for building-wide filtration
- Back through a carbon filter into the same room
Correct answer: Directly outdoors away from re-entry points
Negative air machines must exhaust filtered air directly outdoors, positioned so it cannot re-enter the structure through windows or HVAC intakes.
Question 7: Under which condition should a pneumatic nail gun's sequential-trip trigger mode be selected over bump-fire mode on a restoration site?
- When nailing large sheathing panels quickly
- When working in overhead or awkward positions (Correct answer)
- When the compressor output exceeds 120 PSI
- When nailing into soft wood only
Correct answer: When working in overhead or awkward positions
Sequential-trip mode requires a deliberate trigger pull for each nail, reducing accidental discharge risk in awkward or elevated positions.
