NFPA 70e Training - Arc Flash Safety
By R.W. Hurst, The Electricity Forum
NFPA70E Training Standard
NFPA 70e Training is about learning how to reduce your personal risk of injury and how companies can protect workers from accidental shock and arc flash injury and death.
Our arc flash and shock prevention online training course focuses on the NFPA 70e arc flash standard for electrical safety that addresses arc flash electrical safety requirements for employee workplaces that are necessary for the practical protection of electrical workers.. This live online course is designed specifically for front-line electrical workers, hvac installers designers and safety managers. We teach students how to implement safe work practices and perform a proper risk assessment. Each studfent receives an Arc Flash Training certificate of completion for the course and a continuing education unit credit (CEU) or professional development hour (PDH) credit.

NFPA published its most recent edition of the “NFPA 70e Standard for Electrical Safety in the Workplace”.
This course addresses electrical safety requirements for employee workplaces that are necessary for the practical safeguarding of employees during activities such as the installation, operation, maintenance, and demolition of electric conductors, electric equipment, signaling and communications conductors and equipment, and raceways for the following:
(1) Public and private premises, including buildings, structures, mobile homes, recreational vehicles, and floating buildings
(2) Yards, lots, parking lots, carnivals, and industrial substations
(3) Installations of conductors and equipment that connect to the supply of electricity
(4) Installations used by the electric utility, such as office buildings, warehouses, garages, machine shops, and recreational buildings, that are not an integral part of a generating plant, substation, or control center
Our course covers the full range of electrical safety issues, including safety related work practices, maintenance, special equipment requirements and installation. It focuses on protecting people and identifies requirements that are considered necessary to provide a workplace that is free of electrical hazards. OSHA bases its electrical safety mandates, found in Subpart S part 1910 and Subpart K part 1926, on the comprehensive information found in the standard. NFPA 70e is recognized as the tool that illustrates how an employer might comply with these OSHA standards. The relationship between the OSHA regulations and NFPA 70e can be described as OSHA is the “shall” and the “how.”
This course focuses on the existing NFPA 70e Arc Flash Stadard which leading industry experts on Arc Flash Protection and Mitigation present information on the following

- Meet and exceed OSHA standards for compliance
- Maintain cost-effective operations
Dangers such as shock, electrocution, and arc blast will always be present on the job, but proper safety strategies can minimize the likelihood of injuries and fatalities. NFPA 70E - Electrical Safety in the Workplace - covers the full range of electrical safety issues from work practices to maintenance, special equipment requirements, and installation. In fact, OSHA in the United States already bases its electrical safety mandates on the comprehensive information in this important Standard.
