What are two types of personal protective equipment (PPE) usable against airborne pathogens?

The correct choice highlights the importance of specific respiratory protection in mitigating the risk of airborne pathogens. Respirators are designed to filter out harmful particles and organisms from the air, providing a crucial barrier against respiratory infections and airborne diseases. They form a tight seal around the face and significantly reduce the inhalation of potentially hazardous pathogens.

The mention of a one-way airway relates to medical procedures and emergencies where establishing an airway is critical; however, it is not categorized as PPE in the same context as respirators. Generally, PPE focuses on clothing and equipment designed to protect individuals from hazards, and while a one-way airway is vital, it does not serve the primary function of protection against airborne pathogens.

In contrast, other options present forms of protection like gloves, which are effective against contact transmission, and goggles or shields, which protect against splash or droplet exposure. Caps and coveralls offer protection as well, but they are not specifically aimed at airborne threats. Thus, the focus on respirators as key PPE for safeguarding against airborne pathogens is essential for ensuring safety in environments where such risks are present.
