Which method is used to select the right size respirator for the user?

• A. Fit test
• B. Visual inspection
• C. Color coding
• D. Label reading

Answer: (A)

The essential idea is that a respirator only protects if it fits the wearer’s face and forms a proper seal. A fit test specifically checks this seal for the chosen size (and model) by evaluating whether leakage occurs as the user moves and talks. There are two common approaches: a qualitative fit test, where the user detects a taste or odor to indicate leakage, and a quantitative fit test, which uses instruments to measure the amount of leakage. Visual inspection can reveal obvious damage or wear but cannot determine whether the mask actually seals to the face. Color coding or reading a label might indicate size or model, but they do not confirm an adequate fit. So, conducting a fit test is the process that ensures the right size provides proper protection.
