CEM Safety Compliance & Risk Management 2 — Questions and Answers
Question 1: Under OSHA's Lockout/Tagout (LOTO) standard 29 CFR 1910.147, how often must an authorized employee's LOTO procedure be reviewed?
- Every 6 months
- Annually (Correct answer)
- Every 3 years
- Only after an incident
Correct answer: Annually
OSHA requires periodic inspections of LOTO procedures at least annually for each authorized employee.
Question 2: Which risk assessment matrix dimension measures the likelihood that a hazard will cause harm?
- Severity
- Probability (Correct answer)
- Detectability
- Exposure frequency
Correct answer: Probability
Probability (or likelihood) assesses how often or how likely a hazard event will actually result in harm.
Question 3: A construction crew is working near energized overhead power lines at 50 kV. What is the OSHA-required minimum approach distance for unqualified workers?
- 3 feet
- 6 feet
- 10 feet (Correct answer)
- 15 feet
Correct answer: 10 feet
OSHA 29 CFR 1926.1408 requires unqualified workers to stay at least 10 feet from power lines up to 50 kV.
Question 4: Which document formally identifies hazards, evaluates risks, and establishes control measures before beginning a high-risk equipment task?
- Incident report
- Job Hazard Analysis (JHA) (Correct answer)
- Equipment inspection log
- Safety data sheet (SDS)
Correct answer: Job Hazard Analysis (JHA)
A Job Hazard Analysis (JHA) is a proactive tool that breaks down a task to identify hazards and define controls before work begins.
Question 5: In the hierarchy of hazard controls, which control is considered the MOST effective?
- Administrative controls
- Personal protective equipment (PPE)
- Engineering controls
- Elimination (Correct answer)
Correct answer: Elimination
Elimination removes the hazard entirely and is the most effective control because it prevents exposure at the source.
Question 6: What is the primary purpose of a near-miss reporting program on a construction or equipment management site?
- Satisfy OSHA recordkeeping requirements
- Identify hazards and prevent future incidents before injury occurs (Correct answer)
- Assign blame and disciplinary action
- Calculate workers' compensation premiums
Correct answer: Identify hazards and prevent future incidents before injury occurs
Near-miss programs capture unplanned events that could have caused injury, enabling corrective action before a real incident occurs.
Question 7: Which ANSI/ASSP standard provides the framework for Occupational Health and Safety Management Systems adopted widely in the United States?
- ANSI Z10 (Correct answer)
- ANSI A10.6
- ANSI B56.1
- ANSI Z359
Correct answer: ANSI Z10
ANSI/ASSP Z10 is the U.S. standard for Occupational Health and Safety Management Systems, analogous to ISO 45001.
