Question

when choosing a respirator for your job, you must conduct a ____ test. options: practice, breathing (selected), weight, fit

Explanation:

When choosing a respirator, a fit test checks if it seals properly to the face for effective protection. "Practice" is not a test type here, "Breathing" test isn't standard for respirator selection, and "Weight" is irrelevant. So the correct option related to respirator selection is Fit.

Answer:

Fit (the option with label "Fit")
