Masks
Wear surgical masks in combination with either chin-length plastic face shields or protective eyewear to protect the face, mouth, and nasal cavity when spatter of blood or OPIM or when splashing of blood or OPIM and other body fluids is expected. Masks should be well constructed. The pleated, soft type of mask has a higher filtration than the cup style. A tight seal at the bridge of the nose will minimize eyewear fogging. Use a mask with at least a filtration of 95% of particles 3 to 5 microns in diameter.vi After each patient, and during patient treatment if applicable, masks shall be changed. Microbes pass more easily through moisture, so change the mask if it becomes wet or visibly soiled. Some professionals change masks after an hour of use. Be careful not to touch the mask with soiled gloves if it is to be reused. After each patient, face shields and protective eyewear shall be cleaned; and if visibly soiled, cleaned and disinfected.
