> If you're wearing an N95 mask or respirator, they can't get into the lungs A random N95 mask is not gonna save a random Joe from asbestos. If you study how masks and respirators work, you will find that you need to be clean-shaven, the respirator must match the shape of your face and have a good seal, etc. People who work with hazardous substances spend a good amount of time on this. NHS had to discard huge number of masks during COVID because they weren't the right shape and weren't forming a seal. In some cases, that's good enough - general dust, woodcutting, etc. For highly toxic substances, it won't save you. |
