SafetyCâu 674 / 700
Before an employee is fit-tested for a tight-fitting respirator, what must occur FIRST?
a.The employee must pass a quantitative fit test
b.The employee must wear the respirator for a full shift as a trial
c.A supervisor must select the respirator brand the worker prefers
d.The employee must receive a medical evaluation to determine fitness to wear a respirator
Giải thích
Correct: a medical evaluation to determine the worker can safely wear a respirator must be completed before fit testing and use, because breathing through a respirator adds physiological stress. A fit test comes after, not before, the medical clearance. Wearing it a full shift is not a prerequisite. Brand preference does not drive selection; the hazard and required protection factor do.
