Fit Testing
Fit testing is a procedure used to determine how well a respirator "fits"-that is, whether the respirator forms a seal on the user's face. Before any employee first starts wearing a respirator in the work environment, the employer must perform a respirator fit test.
For all employees wearing negative or positive pressure tight-fitting facepiece respirators, the employer must perform either qualitative or quantitative fit tests using an OSHA-accepted fit testing protocol. In addition, employees must be fit tested whenever a different respirator facepiece is used, and at least annually thereafter.
If an employee has difficulty breathing during a fit test or while using a respirator, the employer must make a medical examination available to that employee to determine whether he or she can wear a respirator safely.
