FFP3 ( with exhalation valve) hospitals : Intensive Care Departments, (because they are in contact with certainly infected patients) - FFP2 ( with exhalation valve) rescuers (because they are in contact with potentially infected people and / or patients). - FFP2 ( without valve) Law enforcement only in the event of an emergency and help from rescuers (because they must be protected but not run the risk of being infected with each other) - FFP2 ( without valve) family doctors and medical guards . Alternatively with valve (but remember that the valve is of help to those forced to use it for a long time in the presence of a potentially ill patient); doctors will be able to combine the surgical mask over the FFP2 mask with valve to limit the diffusion of their exhalation from the valve. - surgical or homemade masks, must use them: all the circulating population , all the people who work or are forced to work, the same law enforcement agencies , the offices open to the public, the food sales staff and, in any case, all people or workers In circulation. For hospital workers, nurses and / or the doctors themselves, when not in the ward, it may be advisable to use the surgical (or if available the FFP2 or FFP3 but without valve or with the addition of the surgical mask in front of the valve) to limit the maximum spread of the infection. Who should not use the FFP2 and FFP3 with valve It is important to know that the fumes come out of the valve of the mask (which is equivalent to spreading the possible contagion, it is like not having them) therefore: -Absolutely not recommended for the population, (they would contribute to contaminating each other); - They are also not recommended for law enforcement officers who are forced to close contact between colleagues; - They are also not recommended for all food departments or fresh food counters; - Not recommended for offices open to the public. Who must use the FFP2 and FFP3 with valve: -Hospitals Intensive Care and Infectivology Departments; -Rescuers 118, Green Cross, Red Cross, or similar; (These categories are presumed to have contacts with infected people or patients) they must make efforts and / or must keep them for a long time. Who must have the FFP2 and FFP3 without valve: - Law enforcement, to be used only and exclusively for emergency interventions or interventions in assistance to the rescuers, in combination with disposable goggles and gloves. In summary: Citizenship must not use valve masks because they can spread the infection. The sales people don'tthey must use valve masks because they can spread the infection. These two categories must use valveless or surgical or homemade masks with heavy tissues that absorb the exhalation and humidity, retaining it and not releasing it. - See more at: http://www.rainews.it/dl/rainews/articoli/coronavirus-vademecum- … 3259bb23fdff.html
