Extension Cord Safety Guide
Reason
Extension cords and power strips are designed for temporary use with small appliances. Improper use—such as overloading a circuit, "daisy-chaining" strips together, or using them for high-wattage items like space heaters—can cause wires to overheat and start electrical fires. These rules ensure our electrical systems remain stable and safe for everyone.

Procedures
- Choosing the Right Equipment
- [ ] Circuit Breakers Only: Ensure all power strips (relocatable power taps) are equipped with internal overcurrent protection (a built-in circuit breaker).
- [ ] UL Listed: Verify that all cords and power strips have a UL (Underwriters Laboratories) safety label.
- [ ] Grounded Plugs: Use grounded (3-prong) extension cords for any appliance that requires a ground.
- [ ] No "Cube" Adapters: Multi-plug "cube" adapters and unfused plug strips are prohibited.
- Proper Setup & Usage
- [ ] Wall Connection: All power strips and extension cords must be plugged directly into a wall outlet.
- [ ] No Daisy-Chaining: Confirm that power strips are NOT plugged into other power strips or extension cords.
- [ ] High-Wattage Appliances: Ensure space heaters, microwaves, and refrigerators are plugged directly into a wall outlet, not a power strip or extension cord.
- [ ] Temporary Use: Standard extension cords should only be used for portable, temporary appliances—not as a permanent wiring solution.
- Safe Placement & Maintenance
- [ ] Visible & Clear: Cords must not run through walls, ceilings, floors, or under doors.
- [ ] No Rugs: Ensure no cords are hidden under rugs or floor coverings where heat can build up or trip hazards are created.
- [ ] Damage Inspection: Check all cords for frays, splices, or brittle insulation. Damaged cords must be discarded immediately.
- [ ] No Physical Impact: Position cords so they are not pinched by furniture or subject to foot traffic.
Note: Improper use of electrical cords is a leading cause of office fires. For long-term power needs, please contact Facility Operations to discuss installing additional permanent outlets.
