Summary

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®"

Workshop Description/Agenda

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®”.

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.
