Technical Report

OSTI ID:7110093
In July, 1984, a preliminary industrial-hygiene survey was performed at Conley Corporation, Tulsa, Oklahoma, where 4,4'-methylene-dianiline (4,4'-MDA) is used as a hardening agent in manufacturing fiberglass epoxy pipe and pipe fittings. Air and hand contact samples from 2 of 6 workers tested showed 4,4'-MDA contamination. Workers with potential exposure wore neoprene rubber gloves. Workers with direct contact with uncured resin wore a medium-weight flock-lined neoprene glove and a heavy rubber glove over the inner glove when handling the resin. Half-face respirators were available for mixing-room workers. These respirators use combination dust/organic vapor replaceable cartridges. Detectable exposure to airborne 4,4'-MDA was noted for two individuals, the extrusion resin mixer and a winding operator at the extrusion fittings machine, 0.011 and 0.0005 mg/m/sup 3/, respectively, each below the present voluntary guideline of 0.8 mg/m/sup 3/.
