Wyoming Pesticide Applicator Certification Practice Test

What is the primary purpose of fit testing in relation to respirators?

1. To test the durability of the respirator

2. To assess its color

3. To select the right size and type

4. To measure breathing capacity

The correct answer is: To select the right size and type

Fit testing is the process of ensuring that a respirator properly fits an individual's face and provides an adequate seal. This is important because a poorly fitting respirator can allow contaminated air to enter, putting the wearer at risk for respiratory illness or injury. Option A, testing durability, is not the primary purpose of fit testing. Option B, assessing color, is unrelated to the function of a respirator. Option D, measuring breathing capacity, is also not the primary purpose of fit testing, although it may be part of a more comprehensive evaluation for certain types of respirators. Therefore, option C, selecting the right size and type, is the correct answer as it directly relates to the primary purpose of fit testing.
