Respirator fit test

Not to be confused with Respirator seal check.

A respirator fit test checks if a respirator properly fits the face of a user. A fitted respirator must be able to separate a user's respiratory system from ambient air.

The test involves tightly pressing the mask against the face (without gaps) to ensure an efficient seal on the mask perimeter. Protection depends on an airtight seal, making testing necessary before entering contaminated air. Mask size and shape correctly fitted to the user's face provides better protection in hazardous environments. Facial hair, such as beards, can interfere with proper fit.
