Despite many controversial thoughts on their expediency, still specialists are thoughts that the mask is dressed in not for the purposes of protecting themselves, but a goal - not to infect others. After all, it can even be a bearer of the virus without apparent symptoms.
How much time is an effective mask?
First protective masks used only surgeons during operations when the patient's body is weakened and need to minimize any risks, including air-drip infections. And also at the same time to protect the face of the doctor himself from the patient's biological fluids. Taking into account the average duration of operations - masks are effective two hours, if necessary, continued protection - physicians are replaced. Exactly the same period of exploitation of protective masks and under normal conditions (not operating). Elements released to human breathing accumulate on the surface of the mask in excessive amounts, after 2 hours - it needs to be replaced by another.
What are masks?
Generally masks can be different: from simple tissue to serious respirators. For example, the FFP class respirators1 Usually used in non-toxic industries, to protect against dust, or small parts. They are not suitable for protection against viral infections. Is it for self-complacency.
FFP Protection Respirator2 Used from the dust of medium toxicity also carcinogenic dust. And most importantly, 94 percent protects against viral infections.

How to wear a mask properly?
95% of people wear protective masks incorrectly. It is such headlines "speculating" recently most media, explaining that most people wear mask not the side. But in fact, there is absolutely no meaning which side to wear a mask light or darker. The main - filter layer is between them.
And the mask itself is primarily used to protect others from contamination. In general, for healthy it is only a part of protection. Because the mask itself does not close the mucous membrane through which the virus can also penetrate the body.
In addition, other elementary recommendations should also be observed:
Do not neglect the rules in general and wear a mask, covering your mouth and nose, not on chin, neck or one ear.
It is also quite important to use the nose lock (a small flexible part from the top of the mask) so that it adjoins the shape of the face.
Do not touch the mask with your hands, while wearing.
Wear a mask only clean hands, carefully before you washed with soap, to process an antiseptic.
Alternative to pharmacy masks
The World Health Organization claims that a homemade mask from a simple tissue is absolutely not effective, because it does not filter the air as necessary. However, there is a way to make a mask at home, which, indeed, will protect.
The main rule is to use multiple layers of cloth. It is best to choose for a mask of textiles with a smooth exterior layer (such as silk), nylon or cotton will fit the middle layer. The main thing is to avoid wool or other materials that can be visible by allergic reactions to the skin.
You need to cut two pieces of tissue triangular shapes, sew the edges, bend one edge and sew inside the bending of the resin, tightener to tighten the bridge to the end. By such a principle of sailing the rear on the other side.
