Fit testing

Fit testing is a process used to ensure that a mask or respirator fits properly on a person’s face, creating a tight seal to effectively filter out harmful particles or contaminants. During the test, the wearer is exposed to a test agent (like a safe aerosol) while wearing the mask, and measures are taken to confirm that no leaks occur around the mask’s edges. A proper fit guarantees the mask’s protective capability, preventing contaminated air from entering and ensuring safety during hazardous situations. Regular fit testing is essential for maintaining effective respiratory protection.
