when choosing a respirator for your job, you must conduct a _____ test.

When choosing a respirator for your job, you must conduct a fit test. This test ensures that the respirator fits your face correctly and provides the necessary protection. Fit testing is critical because an ill-fitting respirator may not offer adequate respiratory protection against workplace hazards. The Occupational Safety and Health Administration (OSHA) mandates fit testing for workers required to use respirators, and it can be conducted using qualitative or quantitative methods to guarantee both comfort and protection.
