Regulations on Safety Management of Oxygen and Acetylene Cylinder Storage and Use
In order to strengthen the storage and use safety of oxygen and acetylene, regulate the use of hazardous gas cylinders, eliminate safety hazards, and avoid major accidents, this regulation is formulated:
1、 Safety management of gas cylinder storage areas
1. The storage location of gas cylinders must meet the requirements of Class II fire prevention buildings and must be inspected and approved by the fire department. There must be a safe distance (50m) between the warehouse and surrounding buildings;
2. Cannot be located together with offices or lounges, and the warehouse must be more than 15m away from manned buildings;
3. The isolation wall of adjacent storage rooms should be a firewall without door and window openings, and any pipelines are strictly prohibited from passing through;
4. There shall be no underground ditches, tunnels, or bottom ventilation holes indoors;
5. Warehouses shall not be located in basements or semi basements;
6. The warehouse should not be close to heat sources and electrical equipment, away from open flames, and the distance from open flames should not be less than 15m;
7. There should be good ventilation and cooling measures, avoiding direct sunlight exposure, and the temperature inside the oxygen tank should not exceed 30 ℃; The temperature inside the acetylene warehouse shall not exceed 40 ℃; The storage area should be dry and prevent rain (snow) and water immersion;
8. No other items shall be stored in the warehouse;
9. There are no electrical devices installed indoors, explosion-proof type must be selected for the exhaust of electric lights, and electrical switches and fuses should be installed outside the warehouse;
10. The warehouse should be equipped with lightning protection devices, and there should be no grounding wires passing through the indoor area;
11. The platform for loading and unloading gas cylinders in the warehouse should have buffering facilities (such as rubber pads, etc.);
12. The warehouse should have a sound "safety management system", and operating procedures should be hung on site;
13. A "No Smoking" sign should be set up inside and outside the warehouse, and the gas cylinder area should be clearly distinguished and clearly marked, such as "Oxygen Danger" and "Acetylene Danger";
14. Smoking, open flames, and spark generating work are prohibited within a 15m range of the storage area, and corresponding warning signs are set up;
15. Dry powder or carbon dioxide fire extinguishers must be equipped in the warehouse, and the use of carbon tetrachloride fire extinguishers is strictly prohibited;
16. It is strictly prohibited to store acetylene cylinders in the same room as oxygen cylinders and flammable materials.
2、 Safety management of gas cylinder stacking
1. Oxygen cylinders can be placed horizontally, while acetylene cylinders are strictly prohibited from being placed horizontally;
2. Gas cylinders should be fixed or secured with railings or brackets to prevent tipping or rolling. It is prohibited to use the cylinder valve or head of the cylinder to secure the cylinder, and the bottom of the cylinder should be protected from corrosion;
3. When storing gas cylinders (including empty ones), the cylinder valve should be closed, the pressure reducer should be removed, and the gas cylinder cap should be worn and tightened;
4. Arrange neatly with the head facing the same direction;
5. Stacking height shall not exceed 3 layers, and a stack of no more than 9 bottles shall be placed vertically;
6. Prohibit placing gas cylinders in areas where they may conduct electricity;
7. Empty and full bottles must be clearly marked on the bottle body (for example, empty bottles can be written as "empty" on the bottle body, and if there is gas, it should be written as "full" or "available"), and empty and full bottles should be stored separately to avoid confusion;
8. Acetylene storage facilities are strictly prohibited from storing chlorine, oxygen, and flammable materials;
9. Acetylene cylinders are strictly prohibited from being placed on rubber or other insulators;
10. Gas cylinders containing gases that are prone to polymerization or decomposition reactions, such as acetylene cylinders, must have a specified storage period (usually three years);
11. The storage capacity of acetylene gas in a single unit cannot exceed 24
