In connection with the rapid spread of coronavirus from China people are looking for personal protection. How effective masks or respirators? And which one is better?
The threat of infection with the novel coronavirus from China raises questions about whether there are reliable means of individual protection from him. Russian manufacturers reported a sharp increase in demand for medical masks. But do they really guarantee protection from contamination?
Will help if the medical mask?
The simplest protection of the skin and respiratory system of different small particles – masks from non-woven materials, which are mounted on the back of the head, the so-called medical (preventive) mask that you can buy at any pharmacy.
For a long time, medical masks were used primarily by surgeons in the operating room. Thus, decreased risk of transmission to the patient possible infection by airborne droplets, and also defended skin doctors from contact with the biological fluids during operations. Effective protection medical mask provides for two hours, then changing it.
In recent times preventive masks have become popular as individual means of protection from viral infections. However, the particular efficiency they do not differ. The virus enters the human body through the mouth, conjunctiva, wounds and cracks, but, above all, through dirty hands. Ordinary medical masks and even safety glasses should serve, first of all, a reminder that dirty hands should not touch your nose or eyes.
Most reliable respirators
What mask will help to protect against the coronavirus? There are several different types of protective masks for the face, from cotton dust to the respirators with filters of three categories, corresponding to the European standard for respiratory protection.
The respirator of protection class FFP1 (Filtering Face Piece) are commonly used for protection against non-toxic dust in agricultural, food, woodworking and construction industries, such as quarries and limestone barriers. Protection from viral infections they do not guarantee.
Respirators class FFP2 protection is able to retain 94 percent of harmful substances. They are used for protection against solid srednerossijsky asbestos, copper, barium, titanium, vanadium, chromium, manganese dust. Respirators are also suitable for working in areas with airborne levels of harmful carcinogenic dusts, fumes and aerosols based on oil and water. They can also be used for protection against influenza and other viral infections.
Respirator protection class FFP3 are the most reliable, filters out 99 percent of solid and liquid particles. They have the largest and most multi-layered filters and indispensable, for example, in the implementation of works with dangerous materials, particularly when grinding and cutting glass, welding stainless steel and aluminum. These respirators are used in areas of highest risk and can protect against dangerous viruses and radiation.
However, no respirators and other personal protective equipment will not help the virus, if the person does not comply with basic hygiene measures. The most important thing is to keep clean hands and surfaces, which are in constant contact.
Sanepidemiology recommended, among other things, to wash hands thoroughly with soap and water (or wipe with disinfectant wipes) after visiting the places of mass congestion of people and before eating, and regularly disinfect surfaces (tables, doorknobs, chairs, gadgets, keyboards, computers).
