Information × Registration Number 0205U006152, 0105U005583 , R & D reports Title To develop the closed-circuit breathing apparatus, chemical oxygen type, for firemen popup.stage_title Head Konopelko Ye.I., Registration Date 09-08-2005 Organization The RESPIRATOR Scientific-Research Institute of Mine-Rescue Work and Fire Safety popup.description2 The breathing apparatus is developed in which the sulphuric acid solution is used as the initiating liquid of the starting device, what allows to don the breathing apparatus having a 2h-cartridge at a temperature up to minus 10°C and a 4h-cartridge at a temperature up to minus 5 °C. Placing the start briquette outside the cartridge results in the greater stability of its operation (inhaled air temperature, breathing resistance, duration). Placing and compactness of the starting device permit to realize its quick disassembly and assembly without dismantling of the other units of the breathing apparatus. The design of the apparatus allows to highten the number of interruptions in the operation up to 5 in the breathing apparatus with the 4h-cartridge and up to 3 in the breathing apparatus with the 2h-cartridge, to make interruptions in the second half of duration and to augment the time of interruptions up to 90 min.
