What is the importance of conducting seal checks on respirators?

Conducting seal checks on respirators is critical because it confirms that there is an adequate seal between the respirator and the wearer’s face. This seal is essential for ensuring that the respirator functions effectively, providing a barrier against airborne contaminants such as asbestos fibers. If the seal is compromised, contaminated air can enter the respirator, rendering it ineffective and putting the wearer at risk of inhaling hazardous substances.

While comfort is an important factor in respirator selection, it does not guarantee protection from exposure to harmful materials. The suitability of a respirator model depends on various factors, including the specific hazard and the environment in which it is used, but this is distinct from the immediate necessity of ensuring a proper seal. Compliance with training requirements is essential for ensuring knowledge and best practices regarding respirator use, but the primary purpose of seal checks is directly related to safety and effectiveness in providing respiratory protection.
