What does a Fit Check ensure for a respirator?

A Fit Check is a crucial procedure performed with a respirator to ensure that it forms a proper seal against the user's face. This is essential because a good seal prevents contaminated air from leaking in around the edges of the respirator, which would reduce its effectiveness in filtering harmful substances or particles. The process involves the user attempting to breathe normally or using specific techniques to detect any breaches in the seal.

While other factors such as comfort level, breathing ease, and appearance are important considerations in the overall usability of a respirator, the primary purpose of a Fit Check is specifically to guarantee that the respirator fits securely on the individual’s face, providing maximum safety from airborne contaminants.
