Arc Flash Electrical Safety NFPA 70E® On-Site Training
The course is designed to help companies fulfill their legal requirements relative to OSHA 29 CFR Part 1910, Subpart S Electrical, and NFPA 70E® "Standard for Electrical Safety in the Workplace®"
The course is designed to help companies fulfill their legal requirements relative to OSHA
29 CFR Part 1910, Subpart S Electrical, and NFPA 70E® “Standard for Electrical Safety in the
It is a comprehensive overview of electrical safety in the workplace. Both OSHA regulations
and the NFPA 70E® 2015 standards are covered to provide a clear overview of proper electrical
safety procedures. The information provided helps learners understand how to reduce
risk and avoid electrical hazards in the workplace while still being productive, which makes
these classes a valuable training tool for trainers, contractors, safety officials, and electricians
in the field.
Participants will receive a college level textbook.
