Title: Epoxy-based production of wind turbine rotor blades: occupational contact allergies. Author: Pontén A, Carstensen O, Rasmussen K, Gruvberger B, Isaksson M, Bruze M. Journal: Dermatitis; 2004 Mar; 15(1):33-40. PubMed ID: 15573646. Abstract: BACKGROUND: An industry producing rotor blades for wind turbines with an epoxy-based technology had experienced an increasing number of workers with dermatitis, among whom the frequency of occupational contact allergy (OCA) was suspected to be underestimated. OBJECTIVE: To investigate the frequency of OCA by patch-testing with a specially profiled occupational patch test series. METHODS: In a blinded study design, 603 workers were first interviewed and thereafter clinically examined. Based on a history of work-related skin disease, clinical findings of dermatitis, or both, 325 (53.9%) of the workers were patch-tested with an occupational patch test series and the European Standard patch test series. RESULTS: Of the 603 investigated workers, 10.9% had OCA and 5.6% had contact allergy to epoxy resin in the standard test series. Contact allergy to amine hardeners/catalysts was found in 4.1% of the workers. Among the workers with OCA, 48.5% reacted to work material other than epoxy resin in the European Standard patch test series. CONCLUSION: Approximately 50% of the workers with OCA would not have been detected if only the European Standard patch test series had been used.[Abstract] [Full Text] [Related] [New Search]
