Input: Text: unusually for this subreddit, this one happened today. i'm a collector of unusual things: military headwear, discontinued banknotes, and, most importantly, gas masks. now, i'm usually pretty safe about the last one. if i'm working with a filter that could be dangerous, i have a pair of chemical-proof gloves and a working mask on. but, today, i was stupid.

i had ordered a soviet gp-5 mask from a lithuanian seller. these are very popular among fellow collectors, if only for their cheap price. all in, i had spent ten dollars. the package arrived on my doorstep at around 1:30 today. knowing that my brother was home, i asked him to take the package in, unbox the mask and filter, and put them together. 

see, i didn't think there would be any issue. the seller indicated to me that the mask and filter belonged to his grandfather, and that it was in fine condition. now, those filters contain white asbestos, but i figured that, if it was in the condition he claimed, i could run one or two tests before taking the mask of permanently. 

i made it home, and took the mask outside to run a test. visually, everything looked fine. but the moment i put it on, i realized i had fucked up. i took a small breath in, and could feel the small particles. i immediately took the mask of and unscrewed the filter, then ran to get my gloves, mask, and magnifying glass. i took a good, solid look, and it confirmed my fears.

this was the real shit.

and i had breathed it in.

somehow, after years of (what i assume was) improper storage, the filter had degraded to such a degree that the asbestos was literally leaking. i put the filter in an airtight hazardous waste bag, and drove to a local disposal to drop it off. i'm not even sure how it had broken down so bad that the asbestos unbound itself from the cotton in the filter, but it happened. i don't think there's going to be any permanent damage, but i'm not going to take risks like that for a long time
