When are user seal checks recommended to be conducted?

User seal checks are essential for ensuring that respirators fit properly and provide the necessary protection against airborne contaminants. Conducting these checks every time the respirator is put on helps to verify that the seal between the respirator and the user's face is intact. This is crucial because even a small gap can significantly reduce the efficacy of the respirator, allowing harmful substances to enter.

Unlike annual checks or checks only after spills, which may overlook changes in fit due to conditions such as facial hair or weight fluctuations, performing a seal check each time ensures continuous safety and effectiveness. This practice reinforces safety protocols and compliance with regulations regarding respiratory protection. Conducting seal checks on a regular basis minimizes the risk of exposure to harmful chemicals while applying herbicides or other hazardous materials, thus safeguarding the user's health.
