  1. Under OSHA's Hazard Communication Standard (HazCom 2012), how many sections must a Safety Data Sheet (SDS) contain?

    Answer: 16 sections

    GHS-aligned SDS documents must contain exactly 16 standardized sections covering hazard identification, composition, first aid, handling, and more.

  2. What is the minimum safe distance from energized overhead power lines rated at 50 kV or below that OSHA requires for uninsulated equipment?

    Answer: 10 feet

    OSHA 29 CFR 1926.550 requires a minimum clearance of 10 feet from power lines up to 50 kV for uninsulated equipment and workers.

  3. Which hierarchy of controls level is considered most effective for eliminating workplace hazards?

    Answer: Elimination

    Elimination — physically removing the hazard — is the most effective control because it removes the source of risk entirely rather than managing exposure.

  4. A Job Hazard Analysis (JHA) should be reviewed and updated when which of the following occurs?

    Answer: An incident or near-miss occurs

    JHAs must be reviewed after any incident or near-miss to determine if the existing hazard controls were adequate or need revision.

  5. What does the term 'competent person' mean under OSHA construction standards?

    Answer: One capable of identifying hazards and authorized to take corrective action

    OSHA defines a competent person as one who can identify existing and predictable hazards and who has authority to take prompt corrective measures.

  6. What is the maximum noise exposure allowed by OSHA for an 8-hour workday without hearing protection?

    Answer: 90 dBA

    OSHA's permissible exposure limit (PEL) for noise is 90 dBA as an 8-hour time-weighted average (TWA) under 29 CFR 1926.52.

  7. Which type of fire extinguisher is appropriate for Class C (energized electrical equipment) fires?

    Answer: CO2 or dry chemical extinguisher

    CO2 and dry chemical extinguishers are non-conductive and rated for Class C electrical fires; water-based extinguishers conduct electricity and are dangerous.
