Description

The utility model relates to personal protective equipment for human skin and relates to an insulating suit with increased tightness (hereinafter referred to as the suit). The suit is designed to protect human skin from gases (vapors) and the liquid phase (drops) of highly toxic and accidentally chemically hazardous substances (AHOV), petroleum products, concentrated acids, alkalis, radioactive dust, bacterial aerosols, open flames, and fire mixtures during liquidation work the consequences of accidents at radiation, chemical and biological (RCB) hazardous facilities within a radius of 50 to 500 m or more from the source of infection.

The operating time in a suit is determined by the time of the protective action of the filtering gas mask, physical exercises and ambient temperature.

The costume is worn on summer and winter clothes of constant wear. At low temperatures, a head insulation is used - a balaclava.

The suit can be used in all climatic zones of Russia at air temperatures from minus 40 to plus 50 ° C, relative humidity from 30 to 95%.

The suit must be operated with filtering gas masks (PMK-S, PMK, PMK-2, PMG-2) and hand protection equipment (protective gloves). If necessary, it is possible to use a suit with insulating gas masks.

Creating costumes of the claimed type is an urgent task at the present time. From the investigated prior art identified a number of technical solutions in the form of descriptions from the Internet, standards, technical conditions given below.

The well-known OZK general defense kit consisting of a protective cap OP-1M (TU 17 RSFSR 04-6788-84) and protective stockings (TU 17 RSFSR 04-6980-84) made of rubberized material designed to protect skin and uniforms during actions in the atmosphere infected with AHOV.

The OZK kit consists of a protective coat, stockings and gloves. A raincoat with a set-in hood, fastens in front on pegs. A protective coat can be used both as a cape and as a jumpsuit, with the help of pegs. Stockings are made with set-in osoyuzki. The volume of the stockings is regulated by the straps on the pegs. Gloves are made of rubber, available in two versions: winter and summer. Winter version - three-fingered, with insulating inserts. The disadvantages of this kit is that the suit transformed from a cloak (jumpsuit) does not provide protection against AHOV vapors and toxic substances.

Known lightweight protective suit L-1 according to TU 17 of the RSFSR 04-5656-82 / TU of military unit 52688 6502, made of rubberized material, the main purpose of which is to protect a person from harmful chemical and bacteriological effects, from radioactive dust, when performing degassing, decontamination and disinfection works. The protective suit L-1 is made in the form of a jacket with a stitched hood, semi-overalls with stitched osoyozki and gloves. On the neck of the jacket there is a strap that fastens on a peg. The bottom of the jacket and sleeves is pulled together with elastic braid. An intermediate strap is sewn to the bottom of the jacket, which is passed between the legs and fastens in front with pegs. The semi-overalls end with osoyuzki, to which the straps are sewn, fastened with pegs for a more tight attachment to the legs. In the upper part of the overall there are shoulder straps. The disadvantages of this suit are: the suit is made in the form of a jacket and semi-overalls, which gives only skin cover when exposed to drops of aggressive, toxic substances, but does not provide tightness when exposed to the fumes of these substances. The costume is made of materials that are not resistant to oils and petroleum products.

Known light protective suit L-1MK according to TU 8572-290-00209600-2013, made of rubberized material, designed to equip EMERCOM units of Russia to work in foci of radioactive, chemical and biological contamination (contamination). It is a special protective clothing of periodic wearing and is used in the area infected with AHOV. The suit is designed to protect skin, clothes and shoes from radioactive dust, exposure to toxic substances, to protect against solutions of acids, water, alkalis, oils, fats, and petroleum products, to protect against harmful biological factors, when performing degassing, decontamination and disinfection works.

The protective suit L-1MK is made in the form of a jacket with a stitched hood and trousers with stitched osoyuzki. The hood of the jacket has a strap on the contact tape to adjust its volume. The hood has a front obturator part for a tight fit to the gas mask. An intermediate strap on the contact tape, which is passed between the legs and fastens in front, is sewn to the back of the lower section of the jacket. On the sleeves of the jacket there are internal elastic cuffs. Jacket sleeves are reinforced with elbow pieces. The bottom of the sleeves and jackets are pulled together with elastic braid. Pants have adjustable straps. Pants reinforced with knee pads. The disadvantages of this suit are that the suit is made in the form of a jacket and trousers, therefore, sufficient sealing in the belt during operation of the suit is not ensured, as well as the low reliability of the suit in places of the front neckline of the hood, because the hood is pulled together with elastic tape, forming folds.

The closest in the presence of matching features and technical nature to the claimed object is a protective suit (jumpsuit) "Trellkem Splash 600" art. С000 33 LLC 00у published on the website https://shop.vostok.ru/catalog/sredstva-zaschity/avariyno-spasatelnoe-snaryazhenie/kostyumy-izoliruyuschie/kostyum-ansell-trellkem-splesh-600-so-vshitymi-sapami polyamide fabric, coated on both sides with PVC, designed for use in non-emergency technological situations to protect against contact with highly dirty or moderately hazardous corrosive chemicals in liquid form:

- work with acids in oil wells;

- operations to clean the internal and external surfaces using aggressive cleaning agents;

- work with herbicides, pesticides, insecticides;

- degassing work;

- work in areas of spill and packing of hazardous chemicals;

- response to oil spills and oil products.

Suit “Trellkem Splash 600” art. С000 33 000 00у is made in the form of overalls, with welds for protection against water and chemicals in liquid form. The set-in hood, along the front neckline is pulled together with a cord and fastened with a strap on a textile fastener. The jumpsuit has a connector fastened with a zipper that goes to the hood, which is covered with straps on the buttons. Sleeves are set-in, shirt type. Bottom of sleeves on cuffs fastened with a strap on a textile fastener. Bottom of trousers with sewn-in boots.

The disadvantages of the known protective suit are:

- low reliability of the suit in the places of the jumpsuit connector, due to the lack of a protective valve in the prototype strips;

- low reliability of the suit in places of the front cutout of the hood, because the prototype hood is pulled by a cord, forming folds;

- low reliability of the suit in the places of the sleeve on the bottom, due to the lack of prototype on the sleeves of the inner elastic cuffs and additional ties elastic band.

- low reliability of the suit in places of the sleeve on the bottom, due to the lack of prototype on the sleeves of the inner elastic cuffs and additional ties elastic braid;

- the design of the suit does not provide for the possibility of putting it on winter clothes;

- the material of the suit does not protect against the liquid phase of highly toxic substances from heat fluxes.
