What is Arc Flash?
Arc flash is a short circuit through air that flashes over from one exposed live conductor to another conductor or to ground. Arc flash incidents are costly and the frequency of reported accidents is increasing - making arc flash issues a very hot topic within OSHA and the overall safety industry.
Arc Flash Regulations (NFPA 70E Standard)
The NFPA 70E 2012 edition instructs employers to conduct an arc flash analysis to determine the amount of thermal energy that could be generated in an arc flash incident. The information is then used to define a flash protection boundary around the potential source, and to determine the level of arc-rated apparel and other personal protection equipment required when employees cross the boundary while they work on or near exposed live parts.
What Causes Arc Flash?
- Coming close to a high-amp source with a conductive object can cause the electricity to flash over
- Dropping a tool or otherwise creating a spark can ignite an arc flash
- Equipment failure due to use of substandard parts, improper installation, or even normal wear and tear
- Breaks or gaps in insulation
- Dust, corrosion or other impurities on the surface of the conductor
