Which statement best describes why a respirator must fit tightly?

• A. To prevent unfiltered air from entering through gaps
• B. To look more professional
• C. To save costs on filters
• D. To be comfortable regardless of fit

Answer: (A)

A respirator must fit tightly to create a seal with the face so that every breath goes through the filter. If there are gaps around the edges, unfiltered air can sneak in, bypassing the filter and letting pesticides reach your lungs. A tight fit is essential for real protection, and it can be affected by facial hair, wrong size, or movement, which is why fit testing and seal checks are important. The other ideas—looking professional, saving on filters, or being comfortable regardless of fit—don’t protect you if air leaks happen.
