Try these questions from our free Electrical Safety Certification practice tests. The correct answer and an explanation follow each question.

  1. Who is defined as an 'authorized employee' under OSHA's lockout/tagout standard?

    • A. Any employee working near the equipment
    • B. A person who locks or tags machines and performs the servicing
    • C. A manager who approves the LOTO permit
    • D. An employee who has been notified of the LOTO procedure

Answer: B. A person who locks or tags machines and performs the servicing

An authorized employee is the worker who implements the energy control procedure by applying lockout or tagout devices and performs the servicing or maintenance.

  • A technician performing maintenance on a distribution transformer measures insulation resistance. Which test method applies a stepped voltage to evaluate insulation condition over time?

    • A. Polarization Index (PI) test
    • B. Dielectric absorption ratio (DAR) test
    • C. Step voltage test
    • D. Hipot (high-potential) test
  • Answer: C. Step voltage test

    The step voltage test applies progressively increasing voltages to identify insulation weaknesses that would not be detected at a single test voltage.

  • How should a worker respond to an electrical hazard that cannot be immediately fixed?

    • A. Ignore the hazard until the next shift
    • B. Alert the team and ensure proper signage is placed
    • C. Attempt to fix the hazard without proper tools
    • D. Continue working around the hazard
  • Answer: B. Alert the team and ensure proper signage is placed

    When an electrical hazard cannot be immediately fixed, the priority is to prevent others from encountering it. Alerting the team ensures awareness, while placing proper signage, such as 'Danger - Electrical Hazard' or 'Do Not Operate' tags, clearly warns personnel and helps isolate the area until qualified personnel can address the issue safely.

  • How should a ESC professional handle a situation where quality control & inspection methods protocols conflict with practical constraints?

    • A. Always ignore the protocols in favor of practicality
    • B. Document the conflict and seek guidance from appropriate authorities
    • C. Make a unilateral decision without consultation
    • D. Avoid addressing the conflict entirely
  • Answer: B. Document the conflict and seek guidance from appropriate authorities
