Extension cord placement mistakes are responsible for thousands of workplace injuries and fires every year. Most of these incidents are preventable — the mistakes that cause them are well-known, and the correct practices are straightforward. Here are the extension cord placement mistakes that cause safety risks, and how to avoid every one of them.
Mistake #1: Cords Across Doorways and Pathways
A cord that crosses a doorway or pathway is a tripping hazard for every person who passes through. This is the most common extension cord placement mistake and one of the most dangerous — a trip in a doorway can cause falls into door frames, walls, or equipment. Never route a cord across any pathway, doorway, or area where people walk. Route along walls instead, or use an overhead solution like the 80ft retractable extension cord reel that delivers power from above without any floor-level cord.
Mistake #2: Cords Under Rugs or Carpets
Routing cords under rugs or carpets hides them from view — which seems like a solution but creates a worse problem. Cords under rugs can't be inspected for damage, generate heat that can't dissipate, and get damaged by foot traffic without anyone noticing. A cord under a rug that develops a fault is a fire risk that's invisible until it ignites. Never route cords under rugs, carpets, or any covering.
Mistake #3: Daisy-Chaining Power Strips
Plugging one power strip into another concentrates the load of multiple devices through a single outlet connection. This overloads the connection point and creates a fire risk. Never daisy-chain power strips. If you need more outlets, run a second strip from a different wall outlet. The 15-foot surge protector with 8 outlets reaches most workstations from a wall outlet without requiring a second strip.
Mistake #4: Using Indoor Cords Outdoors
Indoor extension cords used outdoors are not rated for weather exposure — moisture penetrates the insulation and creates shock and fire hazards. Any cord used outdoors must be outdoor-rated. The BN-LINK outdoor heavy-duty extension cord (12/3 SJTW, yellow, ETL listed) is rated for outdoor use and highly visible. Never use an indoor cord in any outdoor or wet environment, even temporarily.
Mistake #5: Permanent Use of Extension Cords
Extension cords are designed for temporary use — not as permanent wiring. A cord that's been in the same position for months or years is a cord that's been walked on, pinched by furniture, and exposed to heat and wear without inspection. Permanent power needs require permanent wiring — an electrician adding outlets, not an extension cord that's been there so long it's become invisible. The 6-outlet surge protector with individual switches mounted at the workstation is a permanent solution; an extension cord running across the floor is not.
The Cord Placement Audit
Walk your work area and identify every extension cord. For each one: does it cross any pathway? Is it under any covering? Is it plugged into another strip? Is it an indoor cord in an outdoor environment? Has it been in the same position for more than a few months? Any "yes" answer identifies a placement mistake that needs to be corrected immediately.
