PROTECTIVE SUIT OF RESCUER FOR OPERATION UNDER LOW TEMPERATURE Russian patent published in 2016 - IPC F41H1/02 

FIELD: personal items; safety.

SUBSTANCE: invention relates to means of individual safety, and is intended for rescue and repair work under extreme conditions, in particular impact of gaseous and liquid phases of aggressive chemical hazardous substances in chemical industry, as well as in analysis under debris, which require prolonged operation with a vibration-active tool, such as a perforator, hammer, and at low temperatures. This is achieved due to that in protective suit of rescuer, consisting of trousers with protective stockings, shirt with hood, two-finger gloves and inner helmet, wherein trousers are sewed together with stockings, ended with rubber saddle with boots to which ribbon are sewn for fastening to feet, upper part of trousers has shoulder straps and half-rings, and shirt is combined with hood, rear to its bottom cut is stitched intermediate strap that is passed between legs and buttoned to shirt bottom in front, and sleeve end loops, which are put on thumb after putting on gloves, wherein shirt sleeves have cuffs closely fitting to wrist, and hood is fixed on neck belt and a plastic peg, wherein shirt bottom is tightened with an elastic tape and is equipped with a groin belt, and trousers are retained by two straps and buckles of semi-rings and fixed at bottom of bottom, wherein it is additionally equipped with protective vest against electromagnet radiation, protective shell consists of three layers, wherein it is additionally equipped with respirator containing concentric folded filter, a peripheral ring of which changes into conical surface, and obturator is made in form of annular inflatable chamber from elastic material, for tight connection of termination of cone-shaped surface of filter with a shutter respirator is equipped with carcass made from viscoelastic material in form of truncated cone with functional holes on side surface on one side of which by means of ring from elastic material is fixed filter, and on other side by means of clamping part of bladder annular trough-shaped end of frame is fixed shutter, and gloves are vibration-protective, and rescuer footwear for work under low temperature is felted, containing a boot-top, a stop part and main flange arranged at lower side of footstep part, protective sole, a lower side of main bottom is made from EVA material, or from compound of EVA with rubber, or from compound of EVA with PVC, or from compound of EVA with polyethylene, and additionally comprises insert insole with heating of ethylene vinyl acetate or other elastic material, and in heel part of insole is glued piezoelectric element from piezoelectric rubber, for example, polydimethylsiloxane, with thickness 2.5÷5 mm, size 10×10 mm, wherein it is placed in protective cover, and heating thread is connected to at least one piezoelectric cell located in area of heel and/or tip.

EFFECT: technically achievable result is increasing efficiency of rescue workers at low temperatures.
