In the manufacture of aircraft, traditional mechanical techniques are used for the assembly, often combined with chemical techniques. Handling and exposure to metals and chemicals are therefore extensive. Occupational skin diseases in this industry are well known. Irritant contact dermatitis is considered to be more common than allergic contact dermatitis. Common allergic contactants in an aircraft factory are sealants, epoxy resins, epoxy resin accelerators, preservatives, chromates, and nickel. It is important to patch test with work materials since many chemicals used in the trade are not present in commercially available patch-test series. Subungual pulpitis caused by handling of epoxy resins and sealants based on synthetic rubber is considered to be specific for the aircraft industry. Minimizing the contact with skin-irritating chemicals and/or allergenic chemicals by using proper protective clothing when “no touch” techniques cannot be employed is also important.
