An Alternative Approach to Mitigate the Catastrophic Impact of Arc Flash Explosions

摘要

Arc flash explosions are a major cause of death and injury among workers performing routine electrical equipment maintenance and/or inspections. It's estimated that five to 10 arc flash explosions occur every day in the United States, according to the research and consulting firm CapSchell. The US Bureau of Labor Statistics reports that the main cause of electrical worker electrocution from 1992 to 1999 was contact with "live" (energized) equipment and wiring. The hazard exists mostly because of a failure to de-energize and lock out or tag out electrical equipment and wiring.
