When should a fit check be performed?

A fit check should be performed every time the respirator is donned to ensure a proper seal between the respirator and the wearer’s face. This is essential for maintaining the effectiveness of the respirator in preventing exposure to airborne contaminants like asbestos. A fit check verifies that the respirator is correctly positioned and that there are no gaps that could allow contaminants to bypass the filter.

Performing a fit check every time a respirator is put on helps to account for any changes that may affect the fit, such as facial hair, weight fluctuations, or changes in the shape of the face due to factors like aging. This routine check is a critical component of personal protective equipment (PPE) protocols, especially in environments where hazardous materials are handled. A proper fit ensures safety and compliance with health and safety regulations.
