What is the purpose of a respirator fit test?

Explanation:
Ensuring a proper seal on the wearer’s face is what a respirator fit test is about. It checks that the chosen respirator size and model fits that person well enough to prevent leaks around the nose, cheeks, and chin, so protective air from pesticides is effectively filtered. If the seal isn’t good, a different size, model, or strap adjustment is needed until the test confirms a tight fit. This is not about measuring pesticide potency, color compatibility, or battery life, which are unrelated to achieving a secure facial seal and proper respirator protection.
