Welcome to the Arc Flash Info Center

In our work with industrial customers across North America, we're frequently asked about arc flash hazards—what they are, how to protect workers from them, and how various regulations affect plant procedures.

 

Because Mersen has been heavily involved with arc flash testing and research, we have a wealth of experience to share. So we've developed this website to provide a reliable source of information about this vital, still-evolving topic.

 

Here's where you'll find answers to your questions about:

  • The current emphasis on arc flash
  • Hazards created by arc flash and arc blast
  • What you need to do to protect workers and comply with
  • OSHA requirements
  • Regulations that impact plant operations, including NFPA 70 and NFPA 70E
  • Arc flash hazard analysis
  • The hazards of arcing faults
  • Solutions and services Mersen offers

 

We'll be adding to the site regularly, so be sure to register for our "Keep Me Informed" e-mail alerts—we'll send you updates as information becomes available. Visit our FAQs also. Have other questions? E-mail us or call Technical Services for fast, accurate answers.
