CSP Certified Safety Professional (CSP) Random 2 — Questions and Answers
Question 1: Under OSHA's Hazard Communication Standard (HazCom 2012), how many sections must a Safety Data Sheet (SDS) contain?
- 12
- 16 (Correct answer)
- 18
- 10
Correct answer: 16
GHS-aligned SDS must have exactly 16 standardized sections covering identification, hazards, composition, first-aid, and more.
Question 2: Which type of ventilation system captures contaminants at or near the point of generation before they disperse into the work environment?
- General dilution ventilation
- Recirculating ventilation
- Local exhaust ventilation (Correct answer)
- Supply air ventilation
Correct answer: Local exhaust ventilation
Local exhaust ventilation (LEV) captures contaminants at the source, making it more effective and efficient than dilution ventilation for hazardous substances.
Question 3: A safety professional calculates a Risk Priority Number (RPN) in an FMEA. Which three factors are multiplied together to produce the RPN?
- Frequency, Detectability, Impact
- Severity, Occurrence, Detection (Correct answer)
- Probability, Consequence, Exposure
- Likelihood, Severity, Mitigation
Correct answer: Severity, Occurrence, Detection
RPN = Severity × Occurrence × Detection, with each factor typically rated on a 1–10 scale.
Question 4: According to NFPA 70E, an Energized Electrical Work Permit is required when workers must work on energized parts above what voltage?
- 50 volts (Correct answer)
- 120 volts
- 240 volts
- 480 volts
Correct answer: 50 volts
NFPA 70E requires an Energized Electrical Work Permit for work on electrical conductors or circuit parts operating at 50 volts or greater.
Question 5: The 'hierarchy of controls' lists controls in order from most to least preferred. Which control is ranked FIRST?
- Administrative controls
- Personal protective equipment
- Substitution
- Elimination (Correct answer)
Correct answer: Elimination
Elimination — physically removing the hazard — is the most effective control and sits at the top of the hierarchy.
Question 6: The permissible exposure limit (PEL) for an 8-hour TWA exposure to silica (respirable crystalline quartz) under OSHA's Silica Standard is:
- 0.05 mg/m³ (Correct answer)
- 0.10 mg/m³
- 0.25 mg/m³
- 1.0 mg/m³
Correct answer: 0.05 mg/m³
OSHA's 2016 Silica Standard set the PEL for respirable crystalline silica at 50 µg/m³ (0.05 mg/m³) as an 8-hour TWA.
Question 7: Which ergonomic principle is demonstrated when a workstation is adjusted so the worker's elbows remain at approximately 90° during keyboard use?
- Force reduction
- Neutral posture (Correct answer)
- Contact stress elimination
- Repetition reduction
Correct answer: Neutral posture
Maintaining joints in a neutral posture reduces musculoskeletal strain by keeping tendons, nerves, and muscles in their optimal alignment.
