OSHA has a Short Fuse on Arc Flash Consulting-Specifying Engineer
Arc flash, for the record, is a fiery explosion generated from live electrical equipment, such as a motor control center, that typically results from an improperly grounded electrical system.
OSHA currently does not require mandatory electrical upgrades, but it does require the wearing of bulky and uncomfortable PPG “beekeeper” suits that are unpopular with many plant maintenance personnel. The Catch 22, unfortunately, is enforcement, as the situation is very much like speeding; it’s only enforced when someone is caught.
