A surgical face mask is a disposable device worn over the nose and mouth to protect against the spread of airborne particles and bodily fluids. It is commonly used in healthcare settings to prevent the transmission of infectious diseases and to maintain a sterile environment during medical procedures. Surgical face masks are typically made of multiple layers of material, such as polypropylene, and are designed to filter out particles and droplets while allowing for easy breathing. They are secured in place with ear loops or ties and should be discarded after each use to prevent contamination.
