Two employees of a retirement community and an electrical contractor were injured while working on an electrical panel when an arc flash occurred.  The contractor suffered burns to both hands and the other two suffered facial burns and respiratory tract damage.  The cause of the arc flash incident has not yet been determined.  Respiratory tract burns happen from time to time.  Training workers to “take a deep breath, and hold it” helps in operating equipment but is impractical all the time.  Use of a faceshield can help by preventing most of the hot gases from reaching the face.  Most respiratory burns in our experience occur when clothing ignites but this doesn’t seem to be the case in this instance.
