Use cylinders the note
1. The purchase and use of eligible product manufacturing license, shall not be used modified cylinder and cylinders are not checked.
2. Users must deal with to have cylinder filling registered units or distribution unit to buy gas.
3. The place of cylinders in use, shall not be away from heat and open flame, should guarantee the gas cylinder bottles and dry at the same time. Because the nominal pressure, gas cylinders is according to normal circumstances could reach the highest temperature of gas inside the bottle, and consider the appropriate safety margin. So we must prevent the abnormal cases. All flammable or combustion-supporting gas cylinders and fire distance and the distance between the two cylinders shall not be less than 10 meters, dressed up easy aggregation or decomposition reaction of gas cylinders should be avoided radiation, electromagnetic wave, vibration source. The distance to meet, after the reliable protective measures, can shorten appropriately.
4. A cylinder in the summer when using, should prevent sun, rain and water.
5. Combustible gas cylinders or toxic gas cylinders, workshop shall ensure good ventilation.
6. When using oxidizing gas cylinders, the operator should carefully check their own hands, gloves, tools, pressure reducer, cylinder valves with or without contamination such as grease, all that is stained with grease must skim clean, can operate. Because of oil after contact with compressed gas oxide can produce spontaneous combustion.
7. Open or close the cylinder valve (or bus line flowing through the shutoff valves), can only slowly by hand or special wrench, to prevent static electricity at a high speed. Not allowed to use a hammer and chisel, tongs, g wire clamp, long handle screw spanner and other tools to open and close, so as not to damage the valve or make the pressure gauge impact and failure.
8. When found the cylinder valve leakage, or not to get to, or other defects, the valve closed, and will find the defects of use is not easy to rub off the mark label on the bottle, and then back to the gas filling unit processing.
9. Shall not run out of gas inside the bottle, must have the residual stress. The permanent gas cylinders residual pressure not less than 0.05 MPa; Liquefied gas cylinder shall have not less than 0.5 ~ 1.0% filling quantity of residual gas; For the remainder of dissolved acetylene cylinder gas pressure not less than 0.3 MPa. Pressure cylinders for more: one is to prevent flow backward, the second is to facilitate the gas filling unit test.
Cylinders after put into use, to dig, welding gas cylinder repair is not allowed.
11. The cylinder after put into use, it is forbidden to do STH without authorization changes cylinder seal and color tag, it is forbidden to cylinders will be modified.
