Liquid oxygen tanks are also dangerous goods, so you need to pay more attention to them when they are used in transportation. Here I will summarize some precautions of liquid oxygen tanks in detail for you to avoid unnecessary dangers. happen.
1. The liquid oxygen tank gas cylinder should be placed in a well-ventilated place, and the distance between the fire source and the heat source should not be less than 1.5m. Cylinders are strictly prohibited from roasting, boiling with water, or exposing them to the sun. Always check the air tightness of cylinder valves and pipe joints to keep air tight. Use soapy water to check for air leaks, and it is strictly forbidden to use open flames to test leaks.
2. When the liquid oxygen tank is ignited, the ignition should be ignited first, and then the gas should be turned on. This order should not be reversed. Always be supervised when using it.
3. The liquefied gas in the gas cylinder cannot be used up, and a certain excess pressure should be left. The residual pressure should generally be greater than 49.03kPa to prevent air from entering the gas bottle. After the liquefied petroleum gas is used up, the remaining liquid in the bottle is also a kind of flammable material, and it is not allowed to dump by itself to prevent the flow and evaporation of the residual liquid from causing a fire.
4. Liquefied petroleum gas cylinder is a kind of pressure vessel, which should be well maintained and regularly inspected. In the process of transportation and use, prevent the gas cylinder from falling or hitting. It is not allowed to tap the valve to open the bottle with iron. It is necessary to prevent direct sunlight and long-term rain. Cylinders are generally inspected once every two years.
5. Although the explosive range of the liquefied petroleum gas in the liquid oxygen tank is not too wide, its lower limit is small, so it is easy to ignite and explode once it leaks. Because LPG is heavier than air, it flows downward when it leaks in the air, so it accumulates in low-lying places and becomes a hidden danger of gas explosion. Therefore, a place where gas is likely to leak. Only relying on the windows to ventilate is not enough, but also pay attention to the lower part of the ventilation.
6. When it is found that there is a leakage of the liquid oxygen tank in the room, the doors and windows should be opened in time to ventilate to the direction where there is no open flame. Fire is strictly prohibited nearby. After the fault is eliminated, the unique smell can be used before the special smell disappears. The waste liquid leaking on the ground should be covered with sand and removed to a safe place. When the gas cylinder catches fire, immediately close the valve and move it to an open outdoor place. Use dry powder fire extinguishing agent, carbon dioxide fire extinguishing agent or cover with wet sack to extinguish the fire.
7. It is necessary to educate children not to play with liquid oxygen tanks casually, and parents should also learn about its safety knowledge.
The use of liquid oxygen tanks still needs to attract everyone’s attention, which can also reduce the occurrence of danger.
