fit test
A test to determine how effectively a mask or respirator will protect the wearer from inhaled dusts, gases, or pathogens.
Synonym: respirator fit testingPatient care
The tester places the mask on the wearer's face, making certain that it covers the nose and mouth when the wearer is stationary, moves the head and neck, or speaks. Then the tester sprays an aromatic aerosol into the air around the wearer, who is asked if he or she can taste or smell it. A mask that fits properly prevents detection of odor or taste.
