Respirator Fit Testing

Mobile Respirator Fit Testing for Employers

KSA Occupational Services provides on-site qualitative and quantitative fit testing for employees who use tight-fitting respirators. Mobile scheduling helps employers coordinate testing across shifts, facilities, and employee groups.

When Is Respirator Fit Testing Required?

Under OSHA’s Respiratory Protection standard, an employee required to use a tight-fitting respirator must be fit tested before initial use, whenever a different respirator facepiece is used, and at least annually thereafter. The employee must first receive respirator medical clearance.

Qualitative and Quantitative Fit Testing

Qualitative fit testing is a pass-or-fail method that detects leakage using an accepted test agent such as saccharin or Bitrex. It is commonly used for filtering facepiece respirators, including many N95 respirators, and certain half-mask respirators.

Quantitative fit testing uses an instrument to measure leakage and calculate a fit factor. It can be used for tight-fitting respirators when the selected protocol and equipment are appropriate for the respirator and required level of protection.

What Employees Should Bring

Employees should bring the exact make, model, style, and size of respirator they will use. Prescription eyewear and other personal protective equipment that could affect the seal should also be worn during testing. Facial hair or other conditions that interfere with the sealing surface can prevent a valid fit test.

Fit Test Versus User Seal Check

A fit test evaluates whether a specific respirator fits an individual. A user seal check is performed by the wearer each time the respirator is put on and does not replace required fit testing.
