OSHA – Occupational Safety and Health Administration l NFPA 70 E-2012 “A flash hazard analysis be done in order to protect personnel from the possibility of being injured by an arc flash” – requires study to label panels l OSHA “ 29 CFR 1910. 333(a)(1) Live parts to which an employee could be exposed must be de-energized before the employee can work on or near them” unless the employer can demonstrate that de-energizing introduces additional or increased hazards or is infeasible due to equipment design or operational limitations. l De-energize or use Energized Electrical Work Permit (EEWP) to work on energized equipment – Increased Hazard is a very difficult to meet outside 23 – Health/Public Safety sector Has totally changed the way we service equipment 23
