This Safe Work Practice (SWP) will provide YG employees with a set of guidelines or “Do’s and Don’ts” that have been developed to mitigate hazards associated with this work task, as identified through your workplace hazard identification process. All YG employees performing this work task are required to be trained, knowledgeable and competent.
- Check extension cord for UL mark or symbol
- Ensure that the extension cord is adequate for its intended use and the appliances to be plugged in
- Use a three-pronged extension cord when using heavy-duty tools
- Always match the wide blade of the plug with the appropriate outlet slot
- Check extension cords regularly for any damage or worn insulation, loose or exposed parts, or splices
- Unplug, and discard damaged cords
- Make note of extension cords that become hot when plugged in, if this occurs, then unplug immediately and use a heavier cord. If the problem persists, unplug the cord – block the outlet from being used and have an electrician assess the outlet.
- Extensions cords should only be used in dry locations. If water is introduced, turn off the appliance or equipment and unplug the cord
- Use the appropriate length of cord, a cord that is too long may become tangled which could possibly lead to overheating or become a tripping hazard
- Always unplug extension cords when they are not in use
- Always unplug an extension cord from the plug, never by pulling on the cord itself
- Always unroll or uncoil an extension cord to avoid heat retention and possible melting
- Do not force a three-pronged plug into a two-pronged outlet or extension cord.
- Do not force an extension cord into small spaces (i.e., behind furniture)
- Do not put too many electrical cords together as they may overheat and cause a fire
- Do not connect more than one extension cord together. If more are needed, get a cord that is long enough to do the job without stretching it
- Do not use or store interior extension cords outside and are not to be exposed to temperatures below zero
- Do not use extension cords across areas where people walk
- Do not run an extension cord under a doorway, as the door crossing the cord may damage the insulation
- Do not run an extension cord under carpet or rugs, as the weight and friction of people walking over them may lead to damage as well as increase risk of electrical shock or fire
- Do not use a staple or nail gun to secure extension cords
- Do not plug extension cords into a power bar
