What type of face protection is recommended when working with potentially infectious materials?

When working with potentially infectious materials, a face shield is the recommended type of face protection as it provides comprehensive coverage of the face, protecting mucous membranes of the eyes, nose, and mouth from splashes and sprays that may contain infectious agents. Unlike other options, a face shield offers a barrier that extends beyond the lower face area and can also be worn over other forms of respiratory protection, such as an N95 respirator.

Surgical masks primarily protect the wearer from large droplets but do not provide the same level of protection for the eyes. N95 respirators are highly effective for filtering airborne particles but do not cover the entire face and are not designed to protect against splashes or sprays. Simple cloth masks offer minimal protection and are not adequate for situations involving potentially infectious materials, particularly in healthcare settings where a higher level of protection is necessary. Thus, a face shield is the best choice for ensuring comprehensive facial protection in potentially hazardous environments.
