Arc Flash on Youtube
This video is probably the most famous of all online arc flash videos. It shows an arc flash that allegedly occurred at a facility in Colombia, South America, in 2007. An electrician was racking in a breaker box and an arc flash blasted him at close range. We could not find any information on what happened to the worker who was hit by the blast, but life-altering burns or death are likely outcomes.
This is probably the second most-viewed arc flash video online. It shows three workers working in the open door of an exterior electrical substation when an arc flash occurs. They all sustained burns—one was very serious.

Unlike the first two videos, this video has audio and is shot from a close distance; this gives a more visceral sense of the blast’s raw power.

In the Wisconsin arc flash that injured three people (second video in this article), one of the contributing factors cited by OSHA’s investigation was the lack of safety signs, safety symbols and accident prevention tags. All electrical equipment must be clearly labeled with relevant operation and hazard information, as per NFPA and OSHA guidelines.
