Each year, 2,000 workers are admitted to burn centers for extended injury treatment caused by arc flash. Arc flash is an electric current that is passed through the air when insulation or isolation between electrified conductors is not sufficient to withstand the applied voltage. The flash is immediate, but the results can cause severe injury.
The 2015 Edition of 70E's Revision Cycle is not complete and is still in the new process of NFPA’s industry consensus standards updates. Here is how the new process works: Step 1 – Public Input Stage. Public Input Closing Date - First Draft Meeting - Ballot of First Draft - First Draft Report.
A crew was working on upgrading the battery room at a receiving substation. (The room provided emergency power for up to 8 hours.) The electric utility, the Los Angeles Department of Water and Power, had purchased replacement batteries from RSC in Wilmington, CA.
Similar but different - How to tell the difference Between Arc Rated (AR), Flash Fire Rated (FFR) and Flame Resistant (FR). In 2012, NFPA 70E changed the terminology referencing personal protective equipment (PPE); what was formerly referred to as FR (flame resistant) clothing is to be called Arc Rated or AR, according to the standard change.
The Nine Steps of Arc Flash Hazard Analysis: Section 4 of IEEE 1584-2002, Guide for Arc Flash Hazard Calculations, states that the results of the arc flash hazard analysis are used to "identify the flash-protection boundary and the incident energy at assigned working distances throughout any position or level in the overall electrical system."
OSHA offers safety training pretest to bring them up to speed

A test available from OSHA to be completed by employees prior to training can be a valuable aid to ensuring that workers understand arc flash hazards – and the elements and procedures that affect the likelihood of an arc flash occurring.
From OSHA’s final rule for electric power generation, transmission and distribution. OSHA standard Paragraph (l)(8)(i) of § 1910.269 requires the employer to assess the workplace to identify employees exposed to hazards from flames or from electric arcs. This provision ensures that the employer evaluates employee exposure to flames and electric arcs so that employees who face such exposures receive the required protection.
The National Fire Protection Association (NFPA) in October began shipping copies of NFPA 70E 2015, according to Hugh Hoagland of e-Hazard, an electric arc flash safety consultancy and training company.
Numerous arc flash burn injuries and deaths are caused each year by arc-flash explosions. Arc flashes present numerous dangers to electrical workers due to the extremely intense high-level heat generated in an arc flash and the pressure wave from an arc blast incident.
