Electrical safety
Stop using damaged electrical cords
If a cord, plug, or casing is damaged, loose, discoloured, or charred, stop using it and have it checked by an experienced technician.
Last reviewed: 2026-10-12
Why it matters
Exposed wires, loose plugs, and overheating marks can cause electric shock, short circuits, or fire. Wrapping tape around damage does not make it safe.
Wrong action
Continuing to use a damaged cord while it is plugged in or covering exposed damage with tape and switching it back on.
Correct action
Stop use immediately. Switch off and unplug by the plug body only with dry hands, a dry area, and an intact safely reachable plug. Do not touch exposed wires, damaged plugs, or wet areas; tell the employer and arrange qualified inspection.
What to do
- Visually check the cord, plug, and casing before use.
- Stop for damage, looseness, discolouration, burning smell, or unusual heat.
- Switch off and unplug only if safe, dry, and the plug is intact; do not tape-repair it, and arrange qualified inspection through the employer.
If something happens
If a cord smokes, sparks, or shocks someone, do not touch the damaged area. Switch off power only if safe and call 999 immediately.
