Are there any health risks regarding the epoxy system or composite construction?
Working with composites pose several hazards. The chemicals in the resins are both allergens and toxins and the material in the filler and ground glass can both be lung irritants. It is necessary to wear dust masks at a minimum to protect from the solids and filtering paint masks along with good ventilation for exposure to the resins. Allergic reactions, which can vary from skin irritation to respiratory, are rare but should be avoided by limiting exposure to fumes and skin contact. Good common sense care will get nearly everyone through multiple composite planes without difficulty.
