Every type of respirator has a different fit, so no respirator will fit
everyone. Therefore OSHA requires all disposable half-mask and
full-face respirators, as well as, tight fitting supplied air face pieces, to
be fit tested by an approved fit test method, which can be
achieved through the use of one of the test kits found on this page.
Qualitative fit testing involves the introduction of a harmless,
odorous, or irritating substance (such as smoke, saccharin or Bitrex)
into the breathing zone around the respirator being worn. If no odor
or irritation is detected, you have a properly fitted respirator.
