Flame-Resistant Pants

Flame-Resistant (FR) Pants

Electric arcs pose some of the most serious safety hazards for construction, trades and industry workers. Arc blast or flash hazards include high temperatures (hotter than the surface temperature of the sun) over short periods of time (fractions of a second), hot gases, an intense pressure wave from the explosion (like having a hand grenade explode inches away), and shrapnel from vaporized and molten metal particles. Arc-related injuries can range from minor to severe burns, blindness, hearing and memory loss from the pressure wave, broken bones, or death. When a worker is exposed to an arc, the clothing they wear may play a large role in the severity of the potential injury.

New OSHA standards:

  • - Requires that workers be trained in the potential hazards of electric arcs and the flames they can produce by igniting other materials in the area.
  • - Prohibits workers from wearing clothing that, in the presence of an arc, can potentially increase the extent of injury; that is, if the clothing would ignite and continue to burn, or if it melts on the skin. Thus, workers are generally prohibited from wearing clothing materials made entirely of, or blended with, synthetic materials such as acetate, nylon, polyester, or rayon.
