I find myself exploring environments rich in Asbestos, the specific type of asbestos appears to be both pipes and potentially the cladding around them (steam pipes etc), occasionally broken sheets as well. From time to time I'm required to crawl through these types of environments and there is a large amount of dust kicked up in the process. I'm not sure exactly what type of dust this is but since there are numerous warning signs about asbestos in the area I'm fairly certain at least a portion of it is hazardous.
I'm familiar with using respirators with P2/P2N filters however I'm unsure about clothing requirements.
1) If I were to do the above in general-day-to-day clothing and get dust/fibers in my clothing, will thoroughly washing remove the fibers? Do any potential remaining fibers pose a health risk? How can I tell if there are any fibers in my clothes?
2) How do you know when to replace respirator filters (I'm thinking of the face masks with dual cartridges)?
