Boats are made of various materials such as reinforced plastic (plastic composites), metal (aluminum and steel), wood, or plywood. Construction of boats includes several phases from the manufacturing of a mold for the hull to finishing with various materials and chemicals. Therefore boatbuilding is an industry with exposure to a very large variety of chemicals potentially harmful to the skin.
The most significant skin sensitizers in the boatbuilding industry are various thermosetting plastics (epoxy, polyester, polyurethane, acrylic resins, or their additives).
Construction of wooden boats and cabins includes carpentry tasks.
The choice of allergens must be based on the individual exposure, i.e., products used at work must be studied. Patch testing patient’s own materials is recommendable as commercial allergen preparations are often lacking.
