Face Masks and Safety Goggles

Surgical face masks protect all members of the healthcare team and patients from inhaling contaminated aerosol. The effectiveness of surgical face mask lies in their filtration performance, which is only possible when the edges of the mask fit snuggly against the face. Multilayer surgical face masks are especially safe, as they can be fitted and adjusted by means of a flexible bar in the nose area. The mask must be replaced when there is a likely contamination or after becoming moist.

Safety goggles and visors help protect the eyes from blood particles, pieces of tissue, and other infectious materials. It is important that the goggles cover the sides. Goggles need to provide distortion-free and non-restrictive peripheral vision. Visors are suited especially for wearers of glasses. Even when visors cover the entire face, masks must be worn. Safety goggles and visors should be cleaned with a surface disinfectant after every treatment.

Infection Control Term of the Day
The capacitiy of a disinfectant to inactivate viruses. For proving virucidal efficacy of disinfectants, European standards require in vitro tests (quantitative suspension tests; in the European Norms referred to as phase 2/step 1 e.g. EN 14476. The two test viruses required for claiming virucidal activity according to EN 14476 are poliovirus (type 1) and adenovirus (type 5). In Germany, the guidelines of the German Association for the Control of Virus Diseases (DVV) and the Robert Koch Institute (RKI), in deviation from EN 14476, demand additional proof of efficacy against polyomavirus (SV40).
