During a qualitative fit test, the person wearing the respirator is exposed to a test agent, such as a bitter or sweet solution, while performing a series of movements and speaking exercises. If the wearer can taste or smell the agent, it indicates a poor fit and the need for a different size or model of respirator. The process involves several steps:
Selection of the appropriate respirator. Instruction on proper donning and adjustment techniques. Conducting the fit test using a test agent. Verification of the wearerâs ability to detect the test agent.
This test should be performed annually or whenever there is a change in the wearerâs facial characteristics or the type of respirator used.
