OSHA arc-flash injury data analysis

This is an analysis of the number and types of arc-flash injuries reported by OSHA inspectors from April 1984 through June 2007 in the U.S. It considers incidents and injury types by voltage class from 120 V to 240 kV, frequency of incidents by class of equipment and with common tools, and descriptions of several incidents. The incident descriptions show an appalling lack of training and judgment by those injured. This shows the need for more emphasis on deenergization before beginning work. OSHA, Occupational Health and Safety Administration, is part of the U.S. Dept. of Labor.
