Would you as a firefighter wear these?

[u/MightAsswell]

I'm hoping to become a firefighter. In situations where I'm not wearing a SCBA, but there's still smoke or ash around, I think something like this would be a good idea to wear to help prevent inhaling some of the toxic shit in the air. Has anyone tried this before?

I wouldn't wear those as a cop, let alone as a firefighter.
