CEM Safety Compliance & Risk Management 3 — Questions and Answers
Question 1: A crane operator witnesses a load swing unexpectedly due to wind. Under OSHA 29 CFR 1926.1417, what is the operator authorized to do?
- Continue the lift at reduced speed
- Stop the operation if a safety hazard exists (Correct answer)
- Notify the site supervisor and wait for written approval
- Lower the load only if the rigger agrees
Correct answer: Stop the operation if a safety hazard exists
OSHA 1926.1417 grants crane operators the authority to stop and refuse to perform an operation they believe is unsafe.
Question 2: What does TRIR (Total Recordable Incident Rate) measure in equipment and construction safety programs?
- The number of fatalities per 100 full-time workers
- The number of OSHA recordable incidents per 100 full-time equivalent workers (Correct answer)
- The total cost of workers' compensation claims
- The percentage of unsafe acts observed during audits
Correct answer: The number of OSHA recordable incidents per 100 full-time equivalent workers
TRIR = (number of recordable incidents × 200,000) ÷ total hours worked, normalized to 100 full-time equivalent workers.
Question 3: Which type of fire extinguisher is appropriate for use on a Class C (energized electrical equipment) fire?
- Water (Class A)
- CO2 (carbon dioxide) (Correct answer)
- Wet chemical
- Foam
Correct answer: CO2 (carbon dioxide)
CO2 extinguishers are non-conductive and safe for Class C fires involving energized electrical equipment.
Question 4: When performing a pre-operational inspection on a forklift, a crack is found in the mast. What is the correct action?
- Mark the defect and continue operation at reduced capacity
- Report the defect and remove the forklift from service immediately (Correct answer)
- Apply a temporary weld repair and resume work
- Reduce load weight by 25% and notify the supervisor at shift end
Correct answer: Report the defect and remove the forklift from service immediately
OSHA 29 CFR 1910.178 requires that equipment with safety defects be taken out of service and not used until repaired.
Question 5: Under the Americans with Disabilities Act (ADA) and OSHA, what is an employer's obligation regarding emergency evacuation procedures for employees with mobility impairments?
- Provide a separate emergency exit
- Develop a Personal Emergency Evacuation Plan (PEEP) for affected employees (Correct answer)
- Exempt them from evacuation drills
- Post a note on their workstation
Correct answer: Develop a Personal Emergency Evacuation Plan (PEEP) for affected employees
Employers must develop individualized Personal Emergency Evacuation Plans (PEEPs) to ensure safe egress for employees who cannot use standard evacuation routes.
Question 6: Which leading safety indicator is MOST useful for predicting future incident trends on a jobsite?
- Lost-time injury frequency rate
- Number of near-miss reports filed (Correct answer)
- Total workers' compensation cost
- OSHA recordable incident rate
Correct answer: Number of near-miss reports filed
Near-miss reports are a leading indicator because they capture hazardous conditions before injury occurs, enabling proactive correction.
Question 7: A worker is exposed to a noise level of 95 dB(A) for a full 8-hour shift. Under OSHA 29 CFR 1910.95, what is the maximum permissible exposure time at 95 dB(A)?
- 8 hours
- 4 hours (Correct answer)
- 2 hours
- 1 hour
Correct answer: 4 hours
OSHA's permissible noise exposure table limits exposure to 95 dB(A) to 4 hours per day before requiring additional controls.
