Can you smell outside odors through a hazmat suit?

Question

If you're wearing a hazmat suit, can you smell odors outside it?

Answer 1

Absolutely not. If you are wearing a level A or level B suit, then you have a self-contained breathing apparatus providing your air. The only things that would reach your nose would be in that compressed air tank.

If you're in Level C, wearing an air-purifying respirator, you might smell something if you have a leaky mask.

Answer 2

NO
