RE: Respirator for CA??
Long term effects of exposure to epoxies can be devastating. Anywhere from skin rashes, hives, and skin blistering to a condition that mimics cardio-pulmonary failure. Some people can't even be in the same room where wet epoxies are being used after excessive exposure to them. Everything chemical we touch seems to be accumulative.
Anything that severely irritates your eyes or sinuses is not good for you. Your body is telling you all you need to know when your eyes water or your nose runs. Your lungs are telling you when you cough. Your ears tell you when they start ringing/buzzing or you feel an aural pressure change after listening to something loud. The fact that we choose to ignore the warning signs does not remove the negative impacts. I started using the ca adhesives when they were first introduced. As was well except when they fumed and those fumes got in my eyes. It caused a burning sensation and my eyes teared up. After many years of use I'm congested for a day or two after using even small amounts of ca now.
