Due to the potential risk of gas products, such as acetylene flammable and explosive, oxygen oil catches fire, if more than 90% concentration nitrous oxide and oxygen mixed gas can cause depth of anesthesia, inhaling high concentrations of nitrous oxide gas for a long time, there is a risk of choking. Inert gas asphyxiation, cylinders fall cause broken bottle head (valve) to fly through the air bottle and so on. So should be paid attention to in the gas use, handling and storage of some security issues. This article only do simple instructions, specific safety matters welcome to my company.
User after buying gas cylinder, gas cylinder, date of inspection, paint appearance, various kinds of labeling and safety equipment for inspection, confirmed holding gas is correct, the cylinder safety can be used only in good condition. Gas cylinders should be light light discharge during the process of transportation and loading and unloading, it is forbidden to throw, sliding, rolling and violent collisions. Before use should be according to the requirements will be qualified, the pressure reducing valve is connected to the cylinder valve, matching the connect hose and clean. Different gas cylinders using pressure reducing valve is not the same.
Gas cylinders to position, and to do well the measures to prevent dumping. When welding, gas and electrical take appropriate protective measures. Do not use damaged equipment, such as hose, cable and welding torch, etc.
Should not be in a closed space with an inert gas such as nitrogen, carbon dioxide, etc.) on experimental analysis, welding, low temperature cold storage, blowdown, and so on. In may cause reflux using occasions, use devices must be equipped with intrusion prevention device, one-way valve, check valve, flame arrester, etc. All users must use acetylene cylinder pressure reducer in export parts loaded check valve and flame arrester to prevent backflow and tempering, at the same time in oxygen tank pressure reducer parts exports after loaded check valve to prevent the reverse flow of acetylene. Before using acetylene, all pressure reducing valve, welding torch, hose and acetylene cylinder used soap water leakage test, in case of acetylene gathered in the air. Acetylene bottle placed some distance with flame shall not be less than 10 m (aerial work, should be parallel to the vertical ground surface distance).
Acetylene cylinder when using must be upright, and to do well the measures to prevent the dumping, it is forbidden to put to use. Acetylene cylinder when used to open and close with a special move hand cylinder valves, and always put on the valve.
Suspended use, must be closed and acetylene cutting tool valve valve, it is forbidden to handheld light of cutting tool adjusting pressure reducer or opening and closing of acetylene cylinder valve. Cylinders in use process found leakage to timely treatment, it is strictly prohibited to leak. Mobile operations, should use special cars move, for acetylene cylinder and oxygen bottles in the same car carrying, must use the burning material baffle plate is separated. Use a cylinder units and individuals shall not by himself to the cylinder valves, fusible plug and other accessories for repair or replacement, it is strictly prohibited for welding repair in a cylinder. Shall not run out of gas inside the bottle, must have no less than 0.05 Mpa/liquefied gas cylinders should leave no less than 0.5 ~ 1.0% filling quantity of residual gas. Bottle of gas in contact with each other can cause burning and explosion, poison gas bottle, not with car transport, such as hydrogen and oxygen, acetylene and oxygen tanks, etc. Acetylene cylinders shall not with oxygen, chlorine gas bottle and room to store flammable items. Gas cylinder storage area should be dry, and have good ventilation, it is forbidden to open fire and other sources of heat, it is forbidden to insolate no smoking near combustible gas cylinders or oxygen bottles, gas cylinders should not come into contact with sparks, flame, heat and electric circuit.
A cylinder cap should be worn when not in use. When using acetylene cylinders do not tear open bottle cap. Du crock design can only bear the general industrial transportation, if after strong vibration, impact, dumping, will damage can't even use. During storage, transport and use du crock cannot make its prostrate, should always keep du crock upright position. Liquefied gas temperature is extremely low, easy to cause frostbite
