CSP Certified Safety Professional (CSP) 2 — Questions and Answers
Question 1: Under OSHA's Hierarchy of Controls, which control measure is considered most effective for eliminating workplace hazards?
- Administrative controls
- Engineering controls
- Elimination (Correct answer)
- Personal protective equipment
Correct answer: Elimination
Elimination physically removes the hazard from the workplace and is the most effective control at the top of the hierarchy.
Question 2: Which OSHA standard requires employers to develop and implement a written Hazard Communication Program?
- 29 CFR 1910.132
- 29 CFR 1910.1200 (Correct answer)
- 29 CFR 1910.147
- 29 CFR 1910.119
Correct answer: 29 CFR 1910.1200
29 CFR 1910.1200 (HazCom Standard) requires employers to maintain a written hazard communication program covering SDSs, labels, and training.
Question 3: A safety professional calculates the Incidence Rate for an establishment with 200 recordable injuries in a year and 500 employees working 40 hrs/wk for 50 weeks. What is the OSHA recordable incidence rate?
- 16.0 (Correct answer)
- 20.0
- 8.0
- 40.0
Correct answer: 16.0
OSHA incidence rate = (N × 200,000) / EH = (200 × 200,000) / (500 × 40 × 50) = 40,000,000 / 2,500,000 = 16.0.
Question 4: Which fire extinguisher class is specifically designed for use on fires involving energized electrical equipment?
- Class A
- Class B
- Class C (Correct answer)
- Class D
Correct answer: Class C
Class C extinguishers use non-conductive agents and are rated for use on fires involving energized electrical equipment.
Question 5: Under the OSHA PSM standard (29 CFR 1910.119), what is the minimum frequency for conducting a Process Hazard Analysis (PHA) revalidation?
- Every 3 years
- Every 5 years (Correct answer)
- Every 7 years
- Every 10 years
Correct answer: Every 5 years
OSHA PSM requires PHA revalidation at least every five years after the completion of the initial PHA.
Question 6: The concept of 'fault tree analysis' (FTA) uses which type of logic to model system failures?
- Probabilistic event trees
- Boolean logic with AND/OR gates (Correct answer)
- Bayesian network inference
- Monte Carlo simulation
Correct answer: Boolean logic with AND/OR gates
FTA uses Boolean AND/OR gates to model combinations of component failures that lead to a top-level undesired event.
Question 7: Which federal agency enforces the Resource Conservation and Recovery Act (RCRA) governing hazardous waste management?
- OSHA
- EPA (Correct answer)
- DOT
- NIOSH
Correct answer: EPA
The Environmental Protection Agency (EPA) administers and enforces RCRA, which governs the generation, transportation, and disposal of hazardous waste.
