What type of PPE specifically protects the mouth and nose?

The correct answer is masks, as they are specifically designed to cover and protect the mouth and nose from airborne contaminants, pathogens, and other potential hazards. Masks help to reduce the risk of inhaling harmful substances and also prevent the transmission of infectious agents, making them essential in health care settings and during situations that involve exposure to respiratory hazards.

In contrast, face shields are designed to protect the entire face from splashes, sprays, and flying debris, but they do not provide direct protection to the mouth and nose as masks do. Goggles are primarily used for eye protection against chemical splashes, impacts, or radiation, and have no function in protecting the respiratory system. Gloves are intended to protect the hands from exposure to contaminants and chemicals, but are irrelevant when it comes to respiratory protection. Masks are thus the only type of personal protective equipment (PPE) in this list that focuses specifically on safeguarding the mouth and nose.
