【 Weak current College 】 air respirator maintenance---Power By 【 China power house network 】

Air ventilator is firefighters entered the smoke, toxic gases, dust or hypoxic environment for fire fighting, rescue and ambulance with a personal protective equipment "one of the three piece", "fire fighters life barrier". With the continuous development of the social economy, and a variety of new fires also day by day increases, disaster environment complicated, frequency of use of air ventilator is constantly increasing, according to the Ministry of public security issued by the city fire station building standards law, which clearly defines a line patrols Squadron must achieve the required number, and outfit in a 1: 1 ratio with complete with steel cylinder. However, in the daily management and widespread neglect of basic level Squadron air respirator maintenance work, how to make air respirator maintenance, fully play its role is to rescue especially chemical disasters key to the success of disposal. On air respirator maintenance, on the following points:
　　
First, the mask of maintenance
　　
Masks from face mirror, dressing mesh glial quickly tie, dual microphone and gas valve connection.
　　
1. surface microscope maintenance, attention to friction and shock to the rough, rigid material to prevent the surface mirror grinding flowers and impact produced and sharpness even damaged.
　　
2. dress ribbons (microphone, the gas supply valve connection port) maintenance. Dress with materials to rubber, usually in the wear is required tightness, not excessive force, while at the same time prevent damage some corrosive substances, found damage repair time.
　　
3. gas valve connects the microphone and the maintenance. Some of the material must not be allowed to enter the inner to plug the holes of the inside and impact damage to the plastic material, causing the rupture of a call does not clear or and air feed valve connection is not secure.
　　
Full cover as per use disinfectants and disinfection after use to avoid cross-infection diseases until after drying cloth with a dedicated.
　　
Second, the back shelf maintenance and maintenance
　　
Back from the back, shoulder strap, belt, cylinders fixed belt and regulator, voltage soft catheter, quick plug, pressure gauge, alarm whistle and supply valve, etc.
　　
1, back, shoulder strap, cylinder fixation belt maintenance. When used, handle with care to prevent collisions and friction with sharp material damage. After each use, as are saturated, the need to dry and ventilated place dried up, the Sun. Save time to tighten the belt into the largest location, ensure better air breathing apparatus to combatants.
　　
2. air supply valve and pressure maintenance soft catheter. Its main role is to provide users with air, gas supply valve is to switch on the gas supply valve and discharge valve emergency flush is used for auxiliary supply, apart from surface microscope product mist over gas and exhaust emissions. When used, according to the instruction manual of operations requires correct use, do not put the connection of the "O" ring in corruption or loss, not to the Sun and contact with corrosive, so as to avoid damage.
　　
3, pressure reducing valve, alarm whistle, quick plugs and pressure gauge maintenance. Pressure alarm whistle, quick connectors, before and after the use must be carefully checked, its device is intact, you can play its role, especially after wetting by water, dry and ventilated place to dry. For a quick plug also have to add some lubricant, guarantee full easy to use. Pressure gauge maintenance: check the cylinder pressure is on it's a check in the check, the more gas to free memory, make sure that the pressure gauges and pressure hoses are not in constant time pressure situations; also cannot use it to measure the value of pressure to avoid overload.
　　
III. compressed air cylinder and cylinder valve maintenance
　　
1 cylinder valve is used to control the gas cylinder switch components, it is necessary to correctly switch, usually need to add some lubricant.
　　
2, compressed gas cylinders are mainly used for storing compressed air, there are steel and carbon fiber. In the air: into the air cannot exceed the rated safe air pressure, air humidity must not be too big, causes the cylinder wall oxidation; while in use can not be violent collision and friction with sharp, the lead cylinders is damaged, then the resulting explosion; necessary to gas cylinders (especially the carbon fibre cylinder) produced a protective sleeve, anti friction damage on. Steel gas cylinder should also wash with a layer of antirust paint, avoid being oxidized gas cylinders; full of external gas cylinders not to the Sun and heat place, avoid damage or cause an explosion.
