Professional protection for everyone
Meanwhile, more and more experts are calling for FFP2-type masks to be integrated into indoor hygiene concepts. “One could, for example, consider whether to prescribe FFP2 masks instead of surgical masks in the operating room, “recently hinted at MedUni Vienna virologist Christoph Steininger in a KURIER interview.
“That would make a lot of sense,” says virologist Norbert Nowotny of the Vienna University of Veterinary Medicine, “because they filter 95 percent of potentially virus-containing particles from the air and protect the carrier from viruses entering the mucous membranes. oral and nasal in the form of aerosols.
While in the spring it was still essential that the small number of medical personnel and high-risk groups be reserved, the federal and state governments should now equip employees with extensive personal contact, such as police officers, with FFP2 masks at all the scopes. In companies where employees have a lot of contact with customers, they must also be provided. The general population should use FFP2 masks without an exhalation valve “so that the user does not contaminate his environment with exhaled viruses”.
Nowotny says that FFP2 masks are only designed for one-time use: “Ideally, you should equip yourself with three masks and wear them one after another, one a day. On the fourth day, the first can be used again.” Hygienic storage is essential: hang it in a dry place. “So you can wear the masks for a week or two as long as they are never really wet or dirty.”
Willinger confirms the efficacy of the FFP2 masks. Usage errors are also rare thanks to the special design. If there is very good ventilation and a safe distance is maintained indoors, “normal protection of the mouth and nose can also offer good protection.”
