Which PPE is required for airborne transmission?

• A. Surgical mask, gown, gloves, and face shield
• B. Gown and gloves
• C. N95 mask only
• D. Fit-tested N95 Mask, gown, gloves, and face shield

Answer: (D)

Airborne transmission requires protecting the wearer’s breathing with a respirator that seals to the face and filters small particles. A fit-tested N95 mask provides the necessary filtration and a tight seal, which is essential for effective protection against aerosols. Pairing that with eye protection (a face shield or goggles) guards the mucous membranes of the eyes, while wearing a gown and gloves adds a barrier for skin and hands against contamination. This combination addresses all routes of exposure in airborne scenarios: inhalation, eye exposure, and contact with contaminated surfaces.

Relying on a surgical mask alone doesn’t offer a tight seal or adequate filtration for aerosols. Gown and gloves protect against contact but don’t address inhalation risk. A respirator without eye protection leaves the eyes vulnerable. Therefore, the most protective and guideline-consistent option is a fit-tested N95 mask along with gown, gloves, and eye protection.
