Electrical Safety and NFPA 70E
2012
Ensure Your Jobs Comply with Important
Safety Standards with Ugly’s Electrical Safety and NFPA 70E®!
Ugly’s Electrical Safety
and NFPA 70E® is the first pocket-sized
summary of NFPA 70E 2012 with comparisons to current OSHA
regulations and the
2011 National Electrical Code®.
Designed for electricians, engineers,
contractors, designers, maintenance workers, instructors, and
students, this invaluable resource provides fast access to the most
commonly referenced sections of the latest NFPA
70E and related safety standards.
In simple, straightforward language,
Ugly’s covers the safety requirements of
electrical systems operating at or below 600 volts, including:
Six-Step Procedures for Establishing an Electrically Safe Work
Condition, Meter Safety, Safe Electrical Work Practices, PPE,
Configurations, Electrical Hazards, and First Aid.
Important updates in the 2012 NFPA
70E include:
- Arc-Rated (AR) vs.
Flame-Resistant (FR)
- Documentation of electrical
safety programs and training
- Tables have been added for
direct-current systems
- New requirements for equipment
labeling
- Employees shall be retrained at
intervals not to exceed 3 years
