The impact of an arc flash fire in Portland, Oregon could have been minimized.
An arc flash is a rapid, explosive discharge of electrical energy that usually results from a short circuit fault.
A small explosion in an underground electrical vault burned a Portland General Electric (PGE) worker recently. Firefighters were called to the location, power went off and evacuations followed. An electrical worker was working on a commercial meter when an arc flash occurred, burning her and starting the fire.
Though further information about the woman and her condition haven’t been released and fire investigators are determining what went wrong, there are general safety precautions that should be taken in areas where arc flashes are likely to occur.
The potential for an injury can be reduced using various techniques such as remote breaker racking, remote door openers and closers, personal protection equipment (PPE) and arc flash warning signs and labels.
