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.

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.

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.
