5 Rules for Using Extension Cords Safely in a Workshop

Use a GFCI extension cord GFCI protection shuts off power if electricity leaks, preventing shock from nicked or damp cords.

Keep the cord off the floor Sawdust is fuel. A spark from a damaged cord lying in sawdust can ignite a fire, even with GFCI protection.

Choose the right gauge Use 12-gauge cord for heavy tools and 14-gauge for lights. Undersized cords overheat and create fire risk.

Never daisy-chain extension cords Plugging one cord into another increases resistance and fire hazard. Use a single cord long enough for the job.

Inspect cords before every use Check for cracks, cuts, or worn insulation. Damaged cords cause sparks and shocks. Replace, don’t patch.
