We report an outbreak of occupational contact dermatitis from an anaerobic sealant. This diagnosis was given to 12 out of 48 exposed workers at two Danish refrigerator factories. Six workers showed a positive patch test reaction to 2-hydroxypropyl methacrylate, a constituent of the sealant. Main causes were insufficient information from the producer and poor work place hygiene.
