Hello electricians and safety nerds. Fabric softener removes the fire rating on fire rated clothing protecting you from arc flash hazards.

Yes, and it will even say so right on the tags. At least it did on the 35 year old bunker gear I wore when I was young and a volunteer fireman in my small rural town. They had special washing instructions right on a big tag sewn on the inside to the coat and pants.

This is pure conjecture, but my guess is that the film of fabric softener left on the clothes would interfere with the fire retardant fibers/may be flammable itself.

From my understanding, the old fire gear I wore as a much younger man, the fabric was treated with special chemicals that could be washed out if not laundered correctly.
