Dermatitis
Conditions
Brief summary
The goal of this observational study it to learn about the prevalence of skin sensitization and dermatitis among epoxy-exposed workers in the wind turbine industry. The main question it aims to answer is: \- What is the prevalence of skin sensitization and dermatitis among workers in the wind turbine industry who are exposed to epoxy? Participants will be asked to perform Patch Test, which is considered the Gold Standard test for identifying the cause of occupational contact allergic dermatitis. Researchers will compare the results of the epoxy-exposed group with those of a control group comprising non-exposed workers from the same industry. This analysis will help determine if there is a higher prevalence of skin sensitization among workers exposed to epoxy.
Detailed description
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.
Interventions
DIAGNOSTIC_TESTPatch Test
The Patch Test will include the European baseline series, as well as the epoxy and isocyanate series. Additionally, specific products commonly used in the workplace, such as glues, resins, and paints, will be prepared and included in the testing.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Prevalence of skin sensitization. | 2-3 days | Allergens will be applied to the participant's back using IQ Chambers® (Chemotechnique) and secured with 4fix® adhesive tape for 48 hours. Readings will be conducted on day 2-3 and, if necessary, on days 4-7, following the ESCD guidelines. |
