Respirator Fit Testing Kits

If you or your employees work in an environment where the air contains harmful gases, fumes, dust or toxins, it's important to wear a respirator for protection. Under the regulations of the Occupational Safety and Health Administration (OSHA), employers must fit test any workers who need to wear respirators on the job.

The purpose of a fit test is to ensure that respiratory hazards cannot permeate the seal of a tight-fitting respirator. The most common method of conducting a fit test is qualitative, relying on the user's senses to gauge the effectiveness of the seal. Respirator fit testing kits contain everything you need to perform a qualitative fit test.

Make Sure Your Respirator Fits Correctly

A respirator can only protect you if it fits your face properly. To test the fit of a respirator, most experts use one of four substances: 

  • Isoamyl acetate, which is also known as banana oil because of the unique scent it produces
  • Bitrex, which has an unmistakably bitter taste
  • Irritant smoke, which can cause coughing
  • Saccharin, which has a sweet taste

If the respirator is correctly sealed, the user should not be able to notice the effects of any of these substances. Relying on a test using one of these substances is the best way to ensure that a respirator fits well enough for use in hazardous conditions.
