CGR-long mobile ventilator tube in the gas production and production areas in prolonged hypoxia. The environment is full of poisonous gas disaster assistance provided respiratory protection. Emergency vehicles and escape from the mobile gas cylinder components for two people to use, regional operations up 50 meters. Long attention and use air respirator use, and note 1. CGR4 × 4 precipitous 6.8/30 mobile gas cylinders cylinder group composed of two independent, Group 2 by one-way between the cylinder and pressure reducer valve control, high-pressure gas cylinders between the two groups will not arise in the back. Each cylinder can only gradually opening Group also opened all the same time, freedom to determine specific needs. A pressure relief valve in each cylinder, high-pressure pipe to vent the high-pressure gas cylinders to facilitate replacement, But no leaks under pressure reducer output of the low-pressure gas cylinders and the other gases. 2, the mobile gas cylinders through waist escape valve combined with the normal use of mobile gas directly under the gas. Need to leave the scene in case of emergencies, they can open the cylinder valve to escape to safety Strip. 3, 30 meters equipped with mobile gas source for tracheal one root, root 2 10 meters for the trachea, the largest superposition length of 50 meters. 30 meters pipe equipped with a Y-shaped links, the two officials also can be used for mobile sources of air compressed air. 4, took special use waist, suspenders, wearing the body to appropriately adjust the belts, straps, waist valve. escape bottle waist positions in the human side (note the waist valve orientation towards rapid socket above), to wear comfortable, Without prejudice to arm suitable activities. Mobile gas for the first trachea under rapid socket by the rapid upward reaches waist valve plugs. then mask-waist valve for the rapid valve inserted the plug socket. can be brought back before the movement did not wear gas masks and then first wife wrist joints directly on the valve. Mobile opened the gas cylinder valve wear breathing masks, breathing freely before entering the work site. If two people to use, and so on were all wearing full well after entering, and attention to maintaining the distance and orientation pulling for each other pipes to prevent accidents. 5, managing the use of respirators should be worn by adequate training before use. Preceded by the use of the gas pressure to meet the inspection requirements of the pressure and wear strict routine inspection found ventilator, mobile gas supply, gas supply to escape failure or hidden troubles may compel use. In the process, if you feel inadequate supply of gas, ineffective breathing, or any other discomfort, should immediately withdraw from the scene. opened the escape of gas supply or withdrawal. 6, the use of a process, the proper protection of managing mobile ventilator tube gas on the long, sharp edges and avoid long pipe for gas, Kok, corrosive media contacts or rough objects to create friction with the tractor to prevent the rule, the designated bad, scratching for trachea. If they inadvertently exposed to corrosive media, wash immediately with clean water and wipe away, a long tube defects such as gas, immediately after injury replacement. 7, if the long ventilator tube gas source close to follow the car can use, should be a separate staff to monitor custody arrangements, to check the source of gas in depleted gas issued a warning about the use of personnel and accident notification.
