What type of respirator offers protection to individuals exposed to airborne chemicals?

• A. N95 respirator
• B. Half-face air-purifying respirator
• C. Full-face respirator with organic vapor cartridges
• D. Surgical mask

Answer: (C)

Airborne chemicals imply vapors or gases, not just solid particles. Protecting against them requires a respirator that specifically filters organic vapors. An N95 is designed to filter particles, so it won’t remove chemical vapors. Surgical masks block droplets and don’t form a real seal or protect against gases. A half-face respirator can filter some gases if equipped with the right cartridges, but it only covers the lower face and may not seal as well or protect the eyes. A full-face respirator with organic vapor cartridges provides a tight seal and filters organic vapors, offering protection for the entire face, including the eyes, which is essential when exposure to airborne chemicals is a concern.
