The history of mascarillas is repeated. At the beginning of the pandemic, the sanitary authorities do not recommend its use — in part — because it has the capacity of the summit and all the citizens. Casi one year later were allowed to undergo medical treatment, but the experts consulted that these are their most secure, claiming that they are high in the transmission of the virus, and in particular, with the circulation of more contagious variants. the British. But if theorics are more effective for freeing contagios, the FFP2, would be mandatory for all, probably not having sufficient production capacity, confirm ‘n EL PAÍS the Association of Employers of Individual Protection Teams (Asepal).
There are countries where you can find the mascarillas without medicines to offer sufficient guarantees. France begins deconstructing the use of barracks, and is preparing a decree to impress the use of higher protection. Authorities believe that citizens use it now in public spaces only for three types of mascarillas: the surgical ones, the FFP2 and the category 1 industrial ones, which filter at least 90% of the microscopic particles. In Germany you can not enter closed spaces (as supermarkets and offices) with mascara hair or hygiene. Tampoco cubrirse con una bufanda o un pañuelo. If the type FFP2, KN95 — individual protection equipment (EPI) —surpassed the quirurgical mascara, more than the anterior ones will also require homologated and 90% superior filter capacity. FFP2 mascarillas are mandatory in Bavaria from Monday.
Alberto Núñez Feijóo, President of the Xunta de Galicia, introduces the debate in Spain. Daría confides that the Government will clarify whether the FFP2 can be obligated to determine places or social conducts. A nosotros nos parece que sí ”, stated in a parliamentary comparison, in which it was announced that the plantation of the president, Pedro Sánchez, at the meeting that will turn the fires.
Fernando Simón, director of the Center for the Coordination of Alert and Sanitary Emergencies, has reviewed the use of chiropractic mascara or EPI (FFP2 or FFP3). “A burgemeester protección, mejor”, said in a comparison last week, while defending the use of mascarillas of the “which complies with the UNE specification”. This type of protection is authorized in Spain in April, subject to the obligation of the tapabocas, with the aim of enabling companies to produce massively and cover all the needs of the population rapidly.
But the use of this type of mascara, as well as the casks, is always more in question. “There are no specific items to complete from the point of view of health,” said Luis Gil, Asepal’s secretary general. EL PAÍS has consulted with the Ministry of Health if it has any changes to the standards on mascara, and has replied that it has been announced at the moment.
The ideals: FFP2 and FFP3
José Jiménez, investigator of the Department of Infectious Diseases at King’s College of London, says that hygienic mascara (tela, papel) and so on all cases “do not have to be allowed”, and that its efficacy depends a lot on the material or of the filters that contengan. “In an ideal world the right thing to do is to have the world of EPI masks (FFP2 and FFP3) because they are the most effective at preventing them from infecting us and allowing us to contact others. Sondeverbod, son mascarillas caras que no todo el mundo puede permitirse, geen siempre hooi available and his time of use is very limited. For that matter, although it is not perfect, I believe that the least acceptable series of surgical mascarillas are those that are used to sanitize and more lift and equip ”.
While the surgeons can count on 15 cents per euro, the EPI type does not exceed the two euros. Taking into account that its life is one of eight hours, while it is used, although it requires an intensive use that costs 60 euros per month. And there are some of the manufacturing issues facing Asepal. An obligation of this type of mascara, which can be seen in Spain as in all of Europe, has the risk that we will encounter debilitating problems. Now it is normal to go to the professionals, but the offer is not prepared as for a global demand for all citizenship “, submits Gil.
Ante este problema, José María Lagarón, investigating officer founder of the group Nuevos Materiales y Nanotecnología del Instituto de Agroquímica en Tecnología de los Alimentos (IATA-CSIC), suggests that all menos’ recommendation is to see a la ciudadanía what the ideal serial LFP2 mascaras are and interiors. “We believe that the virus is mainly contagious through the air and in surrounding areas it accumulates in the aerosols, in the form that the best protection is the EPI. In open spaces, the surgeons can suffice, ”explains.
Secures, if they do well
One of the problems that the sanitary authorities will always argue for is not recommending individual protection teams (EPI) to the general population is that the Mayor will not be able to support it. Although this type of mascara (in which it is called FFP) is the highest, its efficiency resides in that it is perfectly adapted to the car and form with a hermetic space, in the form in which a person exhales it filtered por el cubrebocas. Luis Gil, Secretary of Asepal, explains that such a barbeque as a mascara with holgars in the nariz or in the cara hacen loses this high security, and that the pathogens that are floating in the air in aerosols can be colored by these hues pass by the mascarilla security system. Tampoco supports an extra protection to use double mascarilla if debauched is the quirurgical and even the FFP. Hecho, this is counterproductive, there are geniuses who do not allow it to be perfectly adjusted.
With respect to the surgeons, Jimenez points out that the problem is that his design is thought to prevent anyone from being able to transmit contagious diseases to others. “Sirven to protect what we have in our environment, for which the protection that is granted to the life is very limited. Without embarrassment, if all goes well with our surgical mascarillas and the correct use of the number of infections decreases considerably “, added.
It appears that this type of protection is designed for bacteria, not viruses such as SARS-CoV-2, which causes covid-19. “Traditionally, surgeons are used in surgeries to infect patients and those who are operating [de ahí su nombre] with gotitas exhaladas de su boca. Respiratory viruses as a result of this pandemic do not live with it completely unprotected, but we know that surgeons can penetrate between 35% and 15% of potentially contagious particles. Even though it’s more virulent, as can the British, it’s obvious that we have to take everything more seriously, “she said. An EPI mal puesta, with the antecedents hurricanes can reduce its effectiveness in the middle.
