i was cleaning doing some renovation in my basement my brother told me to get out because there asbestos in that room he said that i'm gonna get cancer i was in that room for about 5 hours or more cutting and nailing there was allot of dust and i did not have on a face mask am i going to get cancer please help me thank you?

I'm thinking a face-mask with a one-way-in and a one-way-out valve, with a long tube on the intake so you can have it take in air from the outside. What do I use? Additionally, what other specialty equipment will protect me from asbestos?

Hey i am planning on going into the Northampton State Hospital in Massachusetts soon to take pictures, but they have signs around and on the buildings saying Asbestos, cancer, and lung disease. I am only going in for about an hour, but I don't want to get contaminated. What would be the proper face-mask to wear? I was thinking about those ones the doctors use or the paper ones you can buy from home depot. Are these safe? I'd rather not go and buy a face mask.

Thanks
Thanks for the tip, I didnt think that amount of time would be bad... The place isn't being worked on, it's just sitting there empty so the asbestos fibers shouldn't be disrupted.
