NFPA 70E Employee Workplace Electrical Safety Requirements Standard 2000 Edition
NFPA 70E describes electrical hazard threats in the workplace. NFPA 70E requires the employer to document workers’ susceptible live contacts when it has been determined that workers will be working within the breakdown protection boundary.
NFPA defines legal electrical exposure levels based on the distance of a worker’s face and chest from potential arc sources while performing specific tasks. Workers should use fire-resistant protective clothing and personal protective equipment, and should wear equipment with an adequate level of protection based on the level of prone electrical contact for the specific job.
