CSP Certified Safety Professional (CSP) Comprehensive 4 — Questions and Answers
Question 1: The Occupational Safety and Health Act of 1970 established which fundamental worker right regarding workplace safety?
- The right to refuse all hazardous work without consequence
- The right to a workplace free from recognized hazards likely to cause serious harm (Correct answer)
- The right to unlimited personal protective equipment at no cost
- The right to conduct independent OSHA inspections at any time
Correct answer: The right to a workplace free from recognized hazards likely to cause serious harm
The General Duty Clause (Section 5(a)(1)) of the OSH Act requires employers to provide a workplace free from recognized hazards that are causing or likely to cause death or serious physical harm.
Question 2: In a quantitative risk assessment, 'risk' is most accurately defined as:
- The severity of potential harm if an incident occurs
- The probability that an undesired event will occur within a given time period
- The product of the probability of an event and the magnitude of its consequences (Correct answer)
- The number of people exposed to a specific hazard annually
Correct answer: The product of the probability of an event and the magnitude of its consequences
Risk = Probability × Consequence; it combines the likelihood of an event with the severity of its outcomes to produce a quantitative risk measure.
Question 3: Which ANSI standard governs the design, testing, and use of industrial safety helmets (hard hats)?
- ANSI Z87.1
- ANSI Z89.1 (Correct answer)
- ANSI Z41
- ANSI Z359.1
Correct answer: ANSI Z89.1
ANSI/ISEA Z89.1 covers requirements for industrial head protection, including Type I and Type II hard hats with Class E, G, and C electrical ratings.
Question 4: A confined space is classified as a 'permit-required confined space' (PRCS) under OSHA 1910.146 when it:
- Has a volume less than 5 cubic feet and requires a worker to crouch to enter
- Contains or has the potential to contain a serious safety or health hazard (Correct answer)
- Has an atmospheric oxygen level below 22% but above 19.5%
- Is located below ground level and has restricted natural ventilation
Correct answer: Contains or has the potential to contain a serious safety or health hazard
A PRCS is any confined space that contains or has the potential to contain a serious safety or health hazard (atmospheric, engulfment, entrapment, or other recognized hazard).
Question 5: Which leading indicator would be MOST useful for proactively measuring safety management system effectiveness?
- Total Recordable Incident Rate (TRIR)
- Days Away Restricted or Transfer (DART) rate
- Percentage of safety observations completed versus planned (Correct answer)
- Workers' compensation costs per employee
Correct answer: Percentage of safety observations completed versus planned
Completion rate of planned safety observations is a leading indicator measuring safety activity before incidents occur, unlike TRIR, DART, and workers' comp costs which are lagging indicators.
Question 6: Under OSHA's Respiratory Protection Standard (29 CFR 1910.134), what is required BEFORE an employee is fit-tested for a tight-fitting respirator?
- Completion of a 40-hour hazardous materials training course
- Medical evaluation to determine the employee's ability to use the respirator (Correct answer)
- Purchase of the specific respirator model approved by the employer
- Atmospheric testing confirming oxygen levels above 19.5%
Correct answer: Medical evaluation to determine the employee's ability to use the respirator
OSHA 1910.134 requires a medical evaluation (typically via OSHA's medical questionnaire) before fit testing or use of a tight-fitting respirator to ensure the worker can safely wear it.
Question 7: The 'bow-tie' risk analysis method visually represents:
- The sequence of quality control steps in a manufacturing process
- Hazard sources on the left (threats), the top event at center, and consequences on the right with controls on both sides (Correct answer)
- Organizational hierarchy from CEO down to frontline workers and their safety responsibilities
- Chemical reaction pathways showing how compounds degrade into hazardous byproducts
Correct answer: Hazard sources on the left (threats), the top event at center, and consequences on the right with controls on both sides
The bow-tie diagram places the critical event (top event) at center, threat/cause pathways on the left with prevention barriers, and consequence pathways on the right with recovery/mitigation controls.
