Fiberglass dermatitis is a skin condition caused by exposure to fiberglass particles. The fibers can cause skin irritation and an allergic reaction.  It is a mechanical irritant contact dermatitis caused by the penetration of small fragments or spicules of fiberglass into the skin's stratum corneum.  Allergic contact dermatitis to the resins that coat the fiberglass fragments occurs less frequently. Symptoms of fiberglass dermatitis include itching, redness, and swelling.  Treatment includes avoiding further exposure to fiberglass, using topical steroids or anti-itch medications, and in severe cases, taking oral antihistamines.
