Is it advisable to fit a respirator so that air can leak in around the face?

Fitting a respirator properly is crucial for ensuring its effectiveness in protecting the user from harmful airborne contaminants. When a respirator is positioned correctly to form a tight seal around the face, it prevents contaminated air from leaking in, which maximizes the protection provided by the device. If air is able to leak in around the face, the respirator cannot function as intended, allowing pollutants to bypass the filter and enter the wearer’s respiratory system.

This underscores the importance of ensuring that respirators fit securely and comfortably to maintain their effectiveness during use. The integrity of the seal is paramount; therefore, it is essential not just for comfort or airflow but for the overall safety and protection of the user when working in environments where respiratory hazards exist.
