Safety, Tools, and Jobsite Practices

What this domain tests

Safety, Tools, and Jobsite Practices tests whether you can work around energized equipment, select the right meter, and control jobsite hazards. Expect lockout/tagout, PPE, test-before-touch, meter CAT ratings, ladder and fall protection, GFCI use, and cable-pulling safety.

Core rules

  • Lockout/tagout means isolate, lock, tag, and verify. Test before touch with a meter you have checked on a known live source or proving unit.
  • Meter CAT ratings matter. CAT II is for receptacle-level circuits; CAT III is for distribution panels and feeders; CAT IV is for service entrance and outdoor conductors. A CAT II 300 V meter is not suitable for a 480 V panel.
  • PPE follows the hazard, not the job title. Arc-rated clothing, safety glasses, gloves, and hearing protection are selected from the task and incident-energy assessment.
  • Use GFCI protection for temporary power and wet locations. Inspect cords and tools before use; remove damaged equipment from service.
  • Ladder safety includes the correct duty rating, three-point contact, and keeping the ladder away from electrical lines. Do not use a metal ladder near energized work.
  • Pulling cable can cause hand and back injuries. Use proper grips, keep communication, and avoid standing in the bight of a rope or cable.

Worked example

A technician needs to measure voltage in a 480 V panel. A coworker offers a CAT II 300 V meter. The technician refuses. The panel is a CAT III location, and the meter's voltage and category ratings are both inadequate for the available fault energy. The correct choice is a meter rated CAT III 600 V or higher, with the correct probes, and the technician should verify the meter on a known source before and after the measurement. The reasoning is that the CAT rating is about transient fault energy, not just the nominal voltage printed on the dial.

Traps

  • Using a meter with the wrong CAT rating.
  • Trusting a non-contact voltage tester for absence of voltage.
  • Removing locks to speed up a task.
  • Using a damaged extension cord without a GFCI.
  • Standing in the bight of a pull rope.
