Wyoming Pesticide Applicator Certification Practice Test

A PAPR, or powered air-purifying respirator, provides respiratory protection by using a battery-powered motor to pull air through a filter, purifying it before it is delivered to the user. This makes option A, a filtration mask, incorrect because a PAPR is not just a mask but an entire system that purifies air. Option B, an oxygen tank, is also incorrect because a PAPR does not provide oxygen but instead purifies the air the user is breathing. Option D, a positive pressure mask, is incorrect because while a PAPR does provide positive pressure to keep unfiltered air out, it also purifies the air. Therefore, the correct answer is C - air purifier.
