Prevalence of Skin Sensitization and Dermatitis Among Epoxy-exposed Workers in the Wind Turbine Industry

Epoxy resin systems are widely used materials in various industries due to their high mechanical, chemical, and thermal resistance. These systems are commonly employed as protective coatings, adhesives, and paints, as well as in the manufacturing of composites in the plastics industry. Epoxy components are well-known sensitizers of the skin. A high prevalence of skin sensitization and dermatitis have been reported among workers exposed to epoxy components. It is recommended to use comprehensive protective equipment when handling epoxy components. In the wind turbine industry, tasks involving epoxy handling, such as lamination and filling procedures, are frequently performed. Recent study have shown a sensitization prevalence of 8.9% among workers performing these tasks, while a previous study reported a high sensitization rate of 10.5% to epoxy resins. Despite efforts to find alternatives to epoxy resin systems and improve protective measures, the use of epoxy has increased, and some countries have implemented more stringent regulations, such as Denmark. In Portugal, there are currently no specific regulations regarding epoxy handling, and no certification is required for working with epoxy. Siemens Gamesa Renewable Energy, in Portugal, faces many skin problems among production workers, however numbers are unknown. Therefore, the main purpose of the study is to evaluate the prevalence of skin sensitization and dermatitis among epoxy-exposed workers in the wind Turbine Industry.
