  1. Which tool is used to verify a circuit is de-energized before beginning work?

    Answer: A non-contact voltage tester or digital multimeter rated for the system voltage

    A non-contact voltage tester or properly rated DMM must be used to confirm zero voltage on all conductors before work begins.

  2. What is the significance of the 'restricted approach boundary' in NFPA 70E?

    Answer: Only qualified workers wearing appropriate PPE may enter this zone due to increased shock risk

    The restricted approach boundary is the innermost shock protection boundary where shock risk is significantly increased, requiring qualified workers and PPE.

  3. Which chemical hazard is most commonly associated with lead-acid batteries in electrical rooms?

    Answer: Hydrogen gas produced during charging, which creates an explosion risk

    Lead-acid batteries emit hydrogen gas during charging; accumulation in an unventilated space can reach explosive concentrations.

  4. What must an electrical contractor do when a near-miss incident occurs on a job site?

    Answer: Document it, investigate root causes, and implement corrective actions to prevent recurrence

    Near-miss incidents are leading indicators of future accidents and must be investigated and corrected to improve safety culture.

  5. Which OSHA recordkeeping form is used to log work-related injuries and illnesses?

    Answer: OSHA Form 300

    The OSHA 300 Log is the standard form employers use to record qualifying work-related injuries and illnesses throughout the year.

  6. When working on a construction site with temporary power, GFCI protection or an assured equipment grounding conductor program (AEGCP) is required by which regulation?

    Answer: OSHA 29 CFR 1926.404(b)(1)

    OSHA 29 CFR 1926.404(b)(1) mandates either GFCI protection or an AEGCP for all 120V single-phase 15A and 20A receptacle outlets on construction sites.

  7. A risk assessment matrix in electrical safety management is used to:

    Answer: Prioritize hazards by combining their likelihood of occurrence with the severity of potential injury

    A risk matrix plots probability against consequence to rank hazards so resources are directed toward the highest-priority risks first.
