15 arc flash mitigation strategies for the data center

BY DAVID G. LOUCKS, Eaton Corporation

Arc flashes—the fiery explosions that can result from short circuits in high-power electrical devices—kill hundreds of workers in the U.S. every year and permanently injure thousands more. They can also wreak financial havoc in the form of fines, lawsuits and damage to expensive equipment. Yet, many data center operators are perilously unfamiliar with both the causes of arc flash events and the serious dangers they pose. This feature focuses on arc flash mitigation strategies to improve arc flash safety in data centers.

As we previously...

While the threat of shock and electrocution from inadvertent contact with energized parts has long been recognized, the arc flash and arc blast hazards have only fairly recently been incorporated into the electrical safety standards.

The U.S. federal agency the Occupational Safety and Health Administration (OSHA) enforces electrical workplace safety standards outlined in the National Fire Protection Association’s NFPA 70E: “Standard for Electrical Safety in the Workplace”. Basic compliance with guidelines in the NFPA 70E 2015 Edition, can be established with a five-step process.
