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.
