When are respirator fit checks performed?

Respirator fit checks are critical for ensuring that a respirator effectively protects the user from airborne contaminants. Performing a fit check every time the respirator is used is essential because it verifies that the respirator forms a proper seal against the user’s face, allowing for optimal protection. Factors such as facial hair, changes in the user’s weight, or adjustments made to the respirator can affect the fit. Conducting a fit check before each use helps ensure that the respirator will function as intended, reducing the risk of exposure to harmful substances.

Regular fit checks are not typically done on a monthly or annual basis alone because these timeframes do not account for the potential for changes that might occur in between uses. Similarly, fit checks aren't limited to after cleaning; they should be performed whenever the respirator is donned, regardless of whether it has been cleaned previously. This practice is crucial in environments where safety and health are at risk due to lead exposure or other hazardous materials.
