![]() The report have concerned as the ordinary and not a useful message. Then in June, 1915 Zelinsky has reported to the "Anti gas commission at Russian technical society in Petrograd". Zelinsky has create the report about his tests to Military Sanitary and Evaquation Department which's boss was Prinz Oldenburgsky, and. The reason of failure of these gas masks were the influential ability to a "sincered persones" However some of them new gasmasks were not bad at all than a gas mask of the College of mines, and in details have appeared considerably much better, these gas masks have not been accepted by Imperial Army. Russian army had huge casualities, but only by September, 1916 after numerous protests this gas mask have withdrawn from army as unusable.įigurovsky in his proceedings has found out in archive documents some advices to use of "dry filters» as from educational institutions, and from separate scientists. In the nearest futaure, as it should be happen- In July, 1916 during gas attack under Smorgon (on July, 19-20th) full disfunction of a gas mask of the College of mines was found out. In May the quantity of gas masks of the College of mines was made about 5 % of total ammount of gas masks of all types which was available, in July their relative quantity has increased to 15 %. One of batch of gas masks has been made under the name «Masks of the prince Oldenburgsky». In April and May such gas masks has been sent to the front. Persevering "inventors" from the College of mines had a great support of the prince Oldenburgsky The reader, has already guessed why: Correct, it was "pulled" someone's by «a strong hand». After small alterations it has been accepted and ordered for production in number of 3,5 million exemplares. Though results of the tests made by the Moscow specialists, specified full un-adequacy of a "gas mask of the College of mines" and need of major changes in construction, its further destiny has turned oddly. Up to spring of 1916 inventors of the College of mines added to natrium lime a usual coal. However as inventors of a "gas mask of Mines college" steal idea belonged to others (Zelinski) they did not know one subtlety - Zelinsky offered not simply coal, but the charcoal, which way of manufacturing process they did not know. D.Zelinsky ( he offer to use it in June, 1915). The same time was known about the new sample of the gas mask filter which had absorbing weight changed in comparison with the first sampleīesides natrium lime, filter exists also the coal offered as a sorbent for active chemicals by professor N. September, 28th it became known that the large order of such gas masks for army is supposed. In September the new sample of this gas mask has been definitively designed. The commission had been ascertained considerable power of this filter in relation to chlorine. F.Schröder (1858-1918) was the chef of the commission July, 8, 1915 the gas mask was be on the way to test, the director of the College of mines the well known physicist-chemist professor I. Especially arranged rubber mouthpiece with the ledges coming for lips and supplied with piece for teeth The filter of a gas mask was attached to mask with a mouthpiece, i.e. In a basis the designs of gas masks earlier used in mine-rescue. The gas mask of the "College of Mines" is developed in the summer of 1915 in the College of mines (St.-Petersburg) by prof A.A.Trusevich. The occurrence of the first Russian gas masks are in details investigated by Figurovsky (in 1942, and 1956). The gas mask on such basis has become history of Russian individual defence with name of “Gasmask of Mines institute” In Russia the first absorbing filling in a filter was a natrium lime ( a mix of slack lime with caustic natrium). German scientists have preferred kieselgur with pumice. And at last it's necessary step to choose from them which one has greatest absorbing ability. Researchers had a huge choice such a agents - oxid aluminium, charcoal, natrium lime, etc. And a new principle has been found very quickly as it was known for a long time for a nonspecific linkage of molecules of the chemical agents based on absorbent agents. And even to make an universal changing elements for the filtering systemīut as poisoning chemical agents already in 1915 used tens chemical compounds, and potential quantity of poisoning agents suitable for use in the battle was estimated in hundreds.Ĭhange of a principe functioning of gasmask was required. And it could be strengthened, increasing quantity of layers inside the filter, and to change them, replacing filler. Protection of "damp masks» has been based on chemical linkage of poisoned chemical agents. The antigas protection developed in 1915-1916 was researched step by step, but the chemical weapon was explored much faster, than defense.
