Which statement about when to wear a respirator is true?

• A. You should wear a respirator when you are exposed to a highly toxic pesticides or applying dust as a space treatment.
• B. You should wear a respirator only after finishing mixing.
• C. You should wear a respirator only if you feel ill.
• D. You should never wear a respirator during space treatment.

Answer: (A)

Wearing a respirator is about protecting your lungs from inhaling hazardous substances during pesticide work. The statement that you should wear a respirator whenever you’re exposed to highly toxic pesticides or when applying dust during space treatment correctly emphasizes preventive protection during the tasks that create inhalation risk. Pesticides can release vapors, aerosols, or dust at mixing, loading, and application moments, so using a respirator during the process reduces exposure before any symptoms appear. Relying on how you feel is unsafe because symptoms of exposure may not show up right away, and harm can occur even when you don’t feel ill. Likewise, saying you should never wear a respirator during space treatment ignores the real inhalation risks from dust or aerosols produced during that work.
