RE: Respirator for CA??
I get pounding headaches from breathing CA fumes. It also bothers my eyes. I have read that the fumes are extremely unhealthy to both eyes and lungs. I use a 3M 6200 disposable repirator. I see they sell many varieties and it is a bit confusing. That helps the lungs.
I have a fan that pulls the fumes away from the work area, that helps my eyes.
What little I have read about the Ca confirms that it is NASTY and should be dealt with accordingly.
I minimize my CA use now. When glueing balsa to balsa, it sure is fast and convenient.
