Should a mask be worn under the face shield?
Compliance Directive CPL 2-2.69 - Enforcement Procedures for the Occupational Exposure to Bloodborne Pathogens states that "Depending on the degree and type of anticipated exposure, protection for the face would consist of a surgical mask in conjunction with goggles or eye glasses with solid side shields or, alternatively, a chin length face shield.(1)” It would be best to assume that in those situations where a face shield is needed to protect against splash or splatter of fluids a mask would also be indicated.
The 1993 Centers for Disease Control and Prevention (CDC) guidelines for dental infection control recommend a mask and protective eyewear or a faceshield(2).
