Electrical Safety Basics

Electricity is not visible

You cannot see an energized conductor. You cannot feel it until you've already made contact. Electrical safety is entirely about establishing physical barriers — distance, insulation, lockout — between workers and energized parts before beginning work. Never rely on visual inspection alone to confirm a circuit is de-energized.

Extension cords

Extension cords are for temporary use only. Inspect cords before every use — cuts, fraying, cracked insulation, and damaged plugs are all reasons to take a cord out of service. Never remove the ground prong. Never run cords through walls, under doors, or across walkways where they can be pinched. Never use a cord as permanent wiring.

Electrical panels

Keep the 3-foot working space in front of all electrical panels clear at all times — no storage, no equipment, nothing. Keep panels closed and latched. Report open knockouts or damaged enclosures to your supervisor. Do not open panels or reset breakers unless you are a qualified worker.

Lockout before work

Before any maintenance on electrical equipment — resetting, cleaning, unjamming — the equipment must be de-energized and locked out by a qualified, authorized employee. Turning it off at the control switch is not lockout. The energy must be isolated at the source and the isolating device must be locked.

Discussion question

Where is the electrical panel for this work area, and does everyone here know who the qualified workers are who can work on it?
