Regulations on the management of oxygen and acetylene cylinders

In order to standardize the safe storage and use of oxygen cylinders and acetylene cylinders in various construction units and prevent accidental injuries, relevant management regulations are formulated. Here, I would like to introduce some relevant information to you, hoping to help you.

Regulations on the management of oxygen and acetylene cylinders

1, horizontal use of oxygen cylinders is prohibited. Because of lying down, once the valve of the oxygen bottle accidentally falls off and runs out of gas, the oxygen bottle will rush forward or spin on the ground because of the huge reaction force of the gas. If there is someone nearby, it may endanger personal safety. When the oxygen cylinder is used vertically, it will avoid similar situations when the gas runs out.

2. Article 50 of the Safety Inspection Regulations for Dissolved Acetylene Gas Cylinders stipulates that "when oxygen cylinders and acetylene cylinders are used at the same time, they shall not be less than a safe distance; The distance from the open flame is generally not less than 10 meter ".

3, "gas welding, gas cutting fire safety operation procedures" stipulated in article 2 "oxygen cylinders and acetylene cylinders should be placed vertically separately, and anti-dumping measures. The safe distance between oxygen cylinder and acetylene cylinder should not be less than 8m to prevent explosion caused by improper use; When not in use, the distance shall not be less than 5m.

4. Only two oxygen cylinders are allowed in the same workplace, one for use and one for standby!

5. According to the regulations, the oxygen bottle shall not use up all the gas in the bottle, and at least a residual pressure of 0. 1Mpa shall be left, so as to blow off the dust and avoid mixing other gases when refilling. So oxygen cylinders and acetylene cylinders can't be mixed.

6, gas cylinder warehouse around 10m distance are not allowed to pile up flammable materials, welding and other open flame operations are not allowed, and smoking is not allowed.

7. Storage cylinders should be equipped with shelves, and the cylinders should be placed vertically. Air bottles can be stacked horizontally, but each layer should be padded with wooden or metal formwork, and the stacking height should not exceed1.5m..

8. Warming devices are not allowed in warehouses where gas cylinders are stored.

9. Oxygen bottles and acetylene bottles placed in the open air should be covered with tents or light panels to avoid sun exposure.

10, oxygen cylinders should be kept and used to prevent oil pollution; It must be stable and reliable when placed, and shall not be mixed with other gas cylinders; No sun exposure, no ignition, to prevent explosion.

1 1. When using, transporting and storing acetylene cylinders, the ambient temperature shall not exceed 40℃.

12, acetylene cylinders must be equipped with special pressure reducer and anti-backfire firearms when used, and must be inspected before work, otherwise it is strictly prohibited; When opening, the operator should stand behind the side of the valve and move slowly.

The service pressure of 13 acetylene cylinder shall not exceed 0.05Mpa, and the gas transmission flow shall not exceed1.5-2.0 m3/hr. ..

14, acetylene cylinders should be fixed to prevent dumping. It is forbidden to use them horizontally. For acetylene bottles placed horizontally, direct use is not allowed. Before using them, they must stand still for fifteen minutes, and then use the pressure reducer, otherwise it will be dangerous. Knocking, collision and other rude behaviors are prohibited.

15, acetylene cylinders should not be close to heat sources and electrical devices, and shading measures should be taken to prevent exposure in summer. The distance from the open flame should be greater than 10 meter, and it should be parallel to the vertical ground when working at high altitude.

16. contact between copper, silver, mercury and its products and acetylene is prohibited. The copper content of copper alloy appliances in contact with acetylene must be higher than 70%.

17, when the workplace moves frequently, it should be installed on a special vehicle, and the acetylene bottle and oxygen bottle should keep a safe distance.

18. The gas in the acetylene bottle in use shall not be exhausted, and the residual pressure shall meet the safety requirements: when the ambient temperature is.

19, acetylene bottles shall not exceed 5 bottles at the use site or in the small warehouse of the team.

20, acetylene bottle empty bottles and real bottles should be separated, neat, and clearly marked.

2 1, acetylene cylinder valve outlet must be equipped with special pressure reducer and flashback prevention device. During normal use, the pressure reducer indicates that the pressure relief shall not exceed 0. 15MPa, and the gas discharge flow shall not exceed 0.05m3/h.L If large flow is required, more than one acetylene cylinder shall be used for gas supply.

22. During the use of acetylene cylinder, the special hand for opening and closing the valve of acetylene cylinder should always be installed on the valve. When temporarily stopping use, the valves of welding and cutting tools and acetylene cylinder valves must be closed. It is forbidden to hold a lighted welding and cutting tool to adjust the pressure reducer or switch the acetylene cylinder valve.

23. Units and individuals that use acetylene bottles shall not repair or replace accessories such as bottle valves and fusible alloy plugs by themselves, and it is forbidden to weld and repair acetylene bottles and bases in use.
