Respirator Fit Testing and OSHA's Newly Modified CNC Protocols
In many of today's workplace environments, a respirator and a proper respirator fit test are critical components of the employee respiratory protection program. Fire service, as well as industrial companies and healthcare professionals, have come to depend on properly fitting respirators for protection from respiratory (inhalation) hazards, such as physical, chemical, and biological hazards. When implemented correctly, a respirator fit testing as part of a written respiratory protection program can help ensure that safe respiratory protection levels are achieved through a properly sized and donned respirator. Passing a quantitative respirator fit test verifies that the respirator is a good size and is donned correctly, as well as provides for a valuable opportunity for training employees about achieving the correct mask fit.
As outlined by OSHA, a "fit test" tests the seal between the respirator's facepiece and your face. The test is required to be performed at least annually for those required to wear a respirator for their job.
