I'm curious how many people are familiar with NFPA 70E standards or even it's existance? I would guess that our Inspector and Instructor members are are of it, but how about the rest of the population here?
Perhaps anyone familiar with it could give us an idea on it's scope and critique on it's usefulness? And others can just let us know if you've ever heard of it or have any knowledge of it's contents.
NFPA 70E - Standard for Electrical Safety Requirements for Employee Workplaces
Good article from the Engineer's Digest. I will start posting this link on other forums.
Quoted from the article: "The latest edition of NFPA 70E includes additional requirements for arc blast, arc flash, and maintenance practices, as well as safety requirements for special equipment and a matrix for specifying PPE."
This new information simplifies how to determine what PPE (Personal Protective Equipment)is needed without being an engineer. The normal electrician working on 480 volt, 3 phase systems can just look at a chart to tell if he needs flash gear and what constitutes his protective clothing and PPE. Someone doing maintenance and not installing or modifying anything would need this standard and other OSHA regulations, but not the NEC. Safe work practices and qualifications should not be in the NEC. The NEC can no longer be considered the Electricians Bible because it can not be inclusive enough to cover everything needed to be safe, efficient, and correct in installation practices.
I am not surprised at the lack of familiarity with 70E, but am dissappointed with the lack of interest. Naturally, there was more interest on the IAEI board. Hopefully there has been more awareness raised than the boards indicate. 70E is a very good standard, especially the tables for PPE and method for determining flash hazard with out a lot of hard calculation. NFPA should encourage awareness of its existence with FPNs in NEC Article 110. That way the word is going out without mandating AHJ enforcement and the NEC is still within its scope as an installation standard.
