What should you do every time you wear a tight-fitting respirator to apply pesticides?

Performing seal checks every time you wear a tight-fitting respirator is essential for ensuring the effectiveness of the respirator in providing protection. A proper seal guarantees that inhaled air is filtered, thus reducing the risk of inhaling harmful pesticide vapors, mists, or particles. Seal checks help to identify any gaps or areas where air may leak, which could compromise the respirator's function and expose the wearer to hazardous substances.

In addition to performing seal checks, it's important to ensure that the respirator is clean, that the air filter is functioning properly, and that the respirator is in good condition, but these actions do not directly ensure that the fit is appropriate at the time of use. Therefore, focusing on the seal check is critical for immediate safety before applying pesticides.
