Responding Firefighthers At First Don't Recognize Arc Flash Injuries

An article on reports on an arc flash that happened in a carpet store.  The explosion injured two men, one of whom was injured critically.  When they first arrived the building was full of smoke and the firefighters did not realize two people coming out of the building were seriously injured.

I just came across a 2009 article in ASSE's Professional Safety called "Arc Blast Hazards - The limitations of metal-clad enclosures to protect workers." It is an article that is worth reading.

The article concludes:

"While metal-clad enclosures often provide excellent protection from the devastating potential of electrical arc blasts, electrical workers and engineers need to understand the limitations of such enclosures to protect the workers on the job. Several circumstances can compromise the integrity of metal-clad enclosures, although most are predictable, meaning arc blast hazards can be effectively controlled."

Rockwell Automation has placed a PDF of the power poiunt slides from a presentation on "Arc Flash Standards and Arc Flash Safety in Motor Control Centers" online. It covers four topics:

1. Arc Flash Related Standards
2. NFPA 70E 2012 Changes Related To Arc Flash
3. Arc Resistant Equipment Considerations
4. Minimizing Exposure To Arc Flash Hazards

You can see the presentation here.
