FIELD: rescue operations.
SUBSTANCE: suit of combat garment of rescuers operating under conditions of burning objects in the presence of flying and falling items of the destructible object is proposed. The suit with flame retardant properties consists of a jacket with sleeves and a hood with a protective transparent element located in working condition on the front part of the head, trousers with suspenders and a rigid belt, boots of flame retardant material resistant to mechanical stress of seismic nature. At that as the fabric for the combat garment top the heat-resistant fabric of yarns of polyphenylene oxadiazol fibre and filament yarn "Rusar" is used. The suit also comprises a protective helmet of company "Cromwell F600" with a high level of comfort, and a protective vest. The protective vest consists of a fabric lining connected with a protective shell, and in the fabric lining the elastic frame racks are secured by clips on the belt of trousers, and the protective shell is attached to the elastic frame racks and comprises internal and external protective packages between which a gasket is placed, made in the form of a tape with the fixed pleats placed with a constant pitch from the side of the protected object, and is sequentially placed in two outer layers, and the outer package facing the surrounding environment of the operator is made multi-layered. Each layer is made in the form of interconnected rings, in which stainless steel is used as the material. The layers are located with overlapping the lumen of the rings by their articulation, and the inner protective package is made three-layered, at that the layer in contact with the outer membrane, and the layer facing the operator's body, are made of perforated polymeric material such as aramid fibres, and the intermediate layer located between them is formed resilient from elastic mesh elements, at that the density of the mesh structure of resilient-elastic mesh elements is within the optimal range of values of 1.2 g/cm3-2.0 g/cm3. At that the wire material of elastic mesh elements is steel EI-708, and its diameter is in the optimal range of values of 0.09 mm-0.15 mm. According to the invention, the protective membrane of the protective waistcoat comprises layers of outer membrane, such as aramid fabric impregnated with a polymer binder, hard-alloy or curvilinear or plain-variable inserts and the inner membranes similar to the outer ones, and the inserts are made of elementary cells fastened with each other and with the membranes by adhesive chemically compatible to the binder of the membranes. The inserts are made of isotropic material such as ceramic, with a minimum linear dimension of the cells exceeding their twice thickness, and for attaching them the elastic glue is used based on the synthetic elastomer such as cast polyurethane. The cells can be made square and located chequerwise or in a shape of regular hexagon.
EFFECT: improvement of efficiency and reliability of the design of clothing for rescuers operating under conditions of burning objects in the presence of flying and falling items of the destructible object.
