Liquid gasification danger: Because the liquefied petroleum gas in the liquefied petroleum gas cylinder is a high-pressure liquefaction method (its original volume is compressed to 1/250), it is poured into the steel cylinder. Once the steel cylinder is placed horizontally, the liquid will immediately flow into the atmosphere and will expand immediately. 250 times, if there is any fire source during the expansion process, it will be dangerous; Risk of heat generation due to friction: when the LPG cylinder is standing, the contact area between the liquid and the gas is small, which is safe; if it is placed horizontally, the contact area between the liquid and the gas is large, which is more dangerous; especially when it is shaken horizontally, the friction area between the liquid and the gas expands 3. The increased frequency will make the liquid vaporize and pressurize and affect its safety. If there is a heat source nearby, there is a danger of explosion; The on-off v...
