Why in the USSR did gas masks with a horn? The secret of "Rogach" is revealed!
Before the beginning of the First World War in Russia, gas masks had only minor distribution. They were used mainly in chemical production, in the mining industry, as well as fire and medicines. Sh-1 became the most common Soviet gas mask shortly before the Great Patriotic War. Refers to category of personal protective equipment equipped with internal common space. The world's first gas mask, protecting the respiratory organs, and the skin of the face from combat poisoning substances, was developed in 1915 by the well-known Russian scientist-chemical Zelinsky and Technologist Kummante, such a gas mask Zelinsky - Kummante, who supplied the Russian imperial army in the First World War. The gas mask had many shortcomings and therefore was the development of more efficient protection models. In the 28th year, a new anti-mash of BN began to produce a new gas mask. The gas mask consisted of a helmet W-1, a valve box, a corrugated tube, a gas mask box and a bag for carrying a gas mask. Sh-1 helmet was included in the sets: BN / BS-T5 and BN / BS-TCH. Masks W-1 were produced up to 36 years, and more perfect O-8 masks came to replace them, Shm-1 and Mod. The first thing that rushes into the eyes when you look at the gas mask with the mask sh-1 is a corrosive protrusion on a mask, which is located in the area of the forehead, why is he needed there? The fact is that pre-war gas masks had such a problem as the formation of condensate inside, and accordingly the fogging of the glass. Ordinary physics: outside the cold air, inside the gas mask as a result of human breathing - warm air, on the inner surface of the gas mask - condensate. With swinging windows, it is not for carrying out combat missions, and even move it is impossible, so to wipe the gas mask with your finger and this fingellogo protempted is provided to the horn, so that this gas mask was called a rich or rhino. When fading a braid, a man's finger was played by a horn inside the gas mask and wiped his glass of exercise. A similar process can be observed on the gas mask of Zelinsky, because the problem with the fog was also on it. To prevent the fogging of glasses in a set with a gas mask, a special soap pencil was walking, which the glass was rubbed from the inside, but he saved not for a long time. With the arrival of W-1 masks and mod-8, the problem with the fogging of the glasses was solved by the fact that in a set to the gas mask, there were special unappropriate films that were inserted from the inside of the gas mask into special attachments and protected the condensate glasses.
