Since 1935, when the first electrical safety standard was published, protective equipment for electrical workers has advanced significantly. Throughout the years, the National Fire Protection Association (NFPA) has created many committees and revised its NFPA 70E standard to give rules for protective clothing against electrical shock and arc flash hazards.
The NFPA formed the Committee on Protective Clothing for Electrical Workers in 1969 to develop standards for protective gear, and the first version of NFPA 70E was issued in 1979 to give guidelines on electrical safety for individuals working on or near energized electrical equipment. Prior to 2000, when the NFPA revised the NFPA 70E to include criteria for PPE to defend against electric shock and arc flash hazards, there were no clear standards for personal protective equipment (PPE).
The NFPA continued to revise its standard, changing the term “flame-resistant” to “arc-rated” in 2009. In 2018, the NFPA modified the NFPA 70E standard to include a revised arc flash PPE classification system.
As technology evolves, it is anticipated that arc-rated PPE for electrical workers may undergo several modifications in the future. With advancements in materials science and the advent of new technologies, it is clear that the industry will continue to witness advancements in electrical worker protective clothing.
Lastly, the history of arc-rated PPE for electrical workers highlights the importance of protective gear in preventing electrical hazards to personnel. As the industry progresses, we may anticipate further developments in protective clothing and other PPE that will enhance worker safety.
