Was in an old, abanoned house from the 80's helping a friend who owned it move some things, take photos (no work/moving dust w/work). To be safe before hand (didn't know until recently, cofirmed all the peeling walls a debris in the hosue did have asbestos, horrible shape inside), I put on 1 cheap, home depot masks on top of each other (w/o the respirators). No other protection.
