Which statement best describes the purpose of respirators?

• A. Respirators are for filtering out pesticide dust droplets, particles, and vapors.
• B. Respirators are for filtering only water vapor.
• C. Respirators generate oxygen.
• D. Respirators clean pesticide residue from skin.

Answer: (A)

Respirators protect the lungs by filtering the air you breathe during pesticide handling, catching dust, droplets, particles, and vapors before they enter your airway. This is why filtering out pesticide dust, droplets, particles, and vapors is the best description of their purpose: they reduce inhalation exposure to the hazardous substances present. They don’t generate oxygen or cleanse skin; removing pesticide residue from skin is done through washing, not inhalation protection. Also, they aren’t limited to filtering only water vapor—the right cartridge or filter is needed for the specific vapors involved, and effectiveness depends on proper selection, fit, and use.
