Use of extension cords/power bars for permanent equipment

The most common-but-easily-avoided hazard on our campuses in 2018 was the use of extension cords or power bars for permanent equipment such as fridges and freezers. This is so commonly practiced that you may not realize that extension cords and power bars cans pose a serious hazard when used as permanent connections. When they are used for anything that draws power continuously they can fail and cause electrical overload, fire, or electrocution.

If you see extension cords or power bars being used as permanent electrical connections, confirm with facility staff that the cord is rated appropriately for its use. If the equipment's energy demand exceeds the load capacity of the cord it may overheat and short-circuit. A permanently installed electrical outlet should always be used for equipment such as fridges, freezers, microwaves, and space heaters. Perhaps you are a researcher who stores irreplaceable research samples in your lab fridge - imagine the impact on your research if the extension cord fails silently!

Other Canadian universities have experienced huge losses as a result of this hazard. In one case an overload of an electrical circuit resulted in a $4.5 million loss. In another, a refrigerator was moved and damaged the electrical cord, causing a $54 million loss.

Remember that frayed, cracked, cut and/or damaged electrical cords with exposed wiring also pose a serious danger to you and your valuable property and should NEVER be used.
