CPE CPE Safety, Risk Management & Regulations Questions and Answers 2 — Questions and Answers
Question 1: ACGIH Threshold Limit Values (TLVs) for hand-arm vibration are based on what primary health concern?
- Carpal tunnel syndrome
- Raynaud's phenomenon (vibration-induced white finger) (Correct answer)
- Elbow epicondylitis
- Rotator cuff tears
Correct answer: Raynaud's phenomenon (vibration-induced white finger)
ACGIH TLVs for hand-arm vibration aim to prevent Raynaud's phenomenon, a vascular disorder causing finger blanching and numbness from prolonged vibrating tool use.
Question 2: Which OSHA standard specifically addresses ergonomics in the shipyard industry?
- 29 CFR 1910.900
- 29 CFR 1915 Subpart Z
- OSHA 3182 (Correct answer)
- 29 CFR 1904
Correct answer: OSHA 3182
OSHA 3182 (Ergonomics for the Prevention of Musculoskeletal Disorders in Shipyards) is the industry-specific ergonomics guideline for the maritime sector.
Question 3: In workers' compensation, which cost category typically represents the largest portion of MSD-related expenses?
- Equipment repair costs
- Indirect costs such as lost productivity, training replacements, and administrative overhead (Correct answer)
- Medical treatment costs only
- Legal fees from OSHA citations
Correct answer: Indirect costs such as lost productivity, training replacements, and administrative overhead
Indirect costs of MSDs — including lost productivity, overtime for replacement workers, training, and administrative time — often exceed direct medical and compensation costs by 4:1 or more.
Question 4: What is the purpose of a 'near-miss' reporting system in an ergonomics safety program?
- Document OSHA violations for citation purposes
- Capture early warning events before injuries occur to enable proactive prevention (Correct answer)
- Assign blame for unsafe acts
- Track productivity losses from ergonomic interventions
Correct answer: Capture early warning events before injuries occur to enable proactive prevention
Near-miss reporting identifies precursor events to injury, enabling organizations to address hazards before they result in actual harm.
Question 5: Which process hazard analysis (PHA) method uses a structured 'what-if' questioning approach to identify ergonomic and process risks?
- FMEA
- HAZOP (Correct answer)
- MORT
- THERP
Correct answer: HAZOP
HAZOP (Hazard and Operability Study) uses systematic 'what-if' guide words to identify how deviations from design intent can cause hazardous conditions.
Question 6: Which metric is used to evaluate the effectiveness of an ergonomics program in reducing injuries over time?
- Total Recordable Incident Rate (TRIR) (Correct answer)
- Number of ergonomic assessments completed
- Budget allocated to PPE
- Employee satisfaction survey scores
Correct answer: Total Recordable Incident Rate (TRIR)
TRIR (Total Recordable Incident Rate) measures recordable injuries per 100 full-time workers and is the standard lagging indicator for evaluating injury prevention program effectiveness.
