Here are a few things you can do to protect yourself and prevent overexposure to epoxy products.
Set up a safe shop/work area: Use equipment and procedures that reduce or prevent exposure to epoxy products. Adequate ventilation is very important, and can be as simple as using window or floor fans. You don't have to spend a lot of money on state-of-the-art air filtration or exhaust systems. Proper storage for epoxy components is also key, such as a dedicated cabinet for storing hazardous materials.
Wear appropriate personal protective equipment (PPE), including a proper respirator, protective gloves, protective clothing, and safety glasses or goggles. The recommended minimum for most epoxy users is gloves, eye protection and protective clothing. Protect yourself from toxic epoxy vapors by wearing a well-fitting respirator with an appropriate organic vapor cartridge.
