FIELD: personal use articles.SUBSTANCE: suit of combat garments for rescuers operating under the conditions of facilities on fire with objects flying and falling down as a result of such facilities collapse contains a rescuer combat jacket possessing fire-proof properties and consisting of a jacket with sleeves and a hood with a transparent protective element (that, when in the operational position, is positioned on the face part of the head) as well as trousers with suspenders and a hard belt and high boots made of a fire-proof material resistant to mechanical impacts of seismic nature; the combat garment top is made of thermally resistant fabric consisting of polyphenyleneoxadiazole fibre yarn and Rusar composite filament; additionally provided for are a highly comfortable Cromwell F600 protective headpiece and a protective vest; the protective vest consists of a textile lining bonded to protective shell; there are resilient framework posts fixed inside the textile lining with the help of fixtures on the trousers waist belt. The protective shell is attached to the resilient framework posts and contains an external and an internal protective packages with an interlay positioned between them represented by a tape with fixed folds positioned at uniform pitch on the side of the object being protected and contained sequentially into two external shells; the external package, turned towards the environment around the operator, is multilayered where each layer is made of interconnected rings of stainless steel. The layers are positioned so that the rings gap is covered by their junction; the internal protective package has three layers; the layer contacting with the external shell and that turned towards the operator's body are made of a perforated polymer material such as aramid while the intermediate layer positioned between them is made resilient, composed of resilient mesh elements, such viscoresilient mesh elements mesh structure density varying with the optimal range of values from 1.2 g/cmto 2.0 g/cm; the resilient mesh elements wire is made of Grade EI-708 steel, such wire diameter varying with the optimal range of values from 0.09 mm to 0.15 mm.EFFECT: enhanced efficiency and reliability of the design of garments for rescuers operating under the conditions of facilities on fire with objects flying and falling down as a result of such facilities collapse with radioactive emission additionally in place.2 tbl, 9 dwg |
