In the recent past I have started using a full face respirator. Currently model 3m 6898 which gives me lots of protection form respiratory stresses. It feels somewhat claustrophobic at first, but after some time it gets easier to use. Just being in a crawlspace can be touch enough, it’s dusty, wet, stinky and usually very close quarters. This face mask allows easier breathing, literally. During an inspection last week, the mold was so bad under the home some of the floor, joists and beams were not visible. There is no way I want to breath that stuff! As you may know, all of this “stuff” getting into your eyes can’t be good for you either.
I wear a disposable Tyvek suit, full face mask, gloves and special shoes at almost every crawlspace.
