Six Powerful Tips for Extension Cord Safety

Extension Cord Time Limits

Extension cords are convenient when you need to plug in something and you can’t reach an outlet. However, they were never intended to be a permanent solution. OSHA standards allow the use of an extension cord for a maximum of 90 days or 3 months.  If you need to use the cord longer than that, you’re required to create a more permanent solution and hardwire whatever you’re plugging in. An extension cord is not a long-term solution.

Extension Cord Inspection

When an extension cord is in use, OSHA requires workers to visually inspect it at the beginning of every shift. If the insulation shows any nicks, cuts, or damage, the cord is removed from service until it is adequately repaired and tested. Cords are also removed from service if the internal wires are exposed or if the insulation is pulling away from the plug or socket ends. Using a damaged cord puts you at risk for electric shock or a fire.

Don’t Strain the Cord

OSHA mandates that when using an extension cord, you must protect it from strain. One way you must do so is to smooth over anything the cord runs through. If it runs through a hole in a wall or a desk, you must install a safety grommet to keep the cord from rubbing against the potentially rough edge

Don’t Stretch the Cord

You must also make sure you’re not unduly stretching or tugging on the cord. if you use a cord that’s just long enough to reach, you may end up pulling the cord perpendicular to the outlet and plug, straining the power cord. Instead, you must always use a cord long enough that there is some slack in it rather than pulling it tightly.

GFCIs Are Required

Ground-fault circuit interrupters (GFCIs) are devices that detect any changes in electricity along a certain path and immediately cut the current if they detect an electricity leak. Some extension cords have GFCIs built in. If yours does not, OSHA requires that you plug the cord into a GFCI-equipped electrical outlet or add a GFCI.

Three-Prong Grounded Cords

OSHA requires that any extension cord used on a job site must be a three-wire grounded cord. These cords always have three prongs. The third prong is ground and is an important safety feature that you should never attempt to defeat. A three-pronged extension cord is always safer than a two-wire cord, which is a light-duty tool for plugging in lamps and other items that draw very little power.
