17 people were killed in the explosion and burning accident in Changchun restaurant. After the accident, the fire brigade quickly dispatched police, and the emergency management department immediately made arrangements to quickly find out the cause of the fire. After the on-site investigation by the investigation team and the investigation by the public security department, it was initially determined that the accident was caused by the leakage of bottled liquefied petroleum gas tanks, which led to an explosion and combustion accident.

The explosion accident in this restaurant was caused by the leakage of liquefied petroleum gas (LPG) tanks, which are indispensable gas supplies in the catering industry, so we should pay special attention to the use specifications when using gas. Before using these equipment, gas leakage safety protection devices with leakage alarm and automatic cut-off functions should be installed correctly in each gas operation room. In case of such an accident, this safety protection device will remind us and play a protective role. When gas is used, smooth ventilation and smoke exhaust should also be maintained in the gas operation room, which will also reduce the occurrence of gas hazards.

When using gas, we must pay attention to its service life. Families who use gas must always check whether the joints at both ends of the rubber hose connecting the gas cooker are fixed with clamps, because the service life of the rubber hose is generally 1.8 months. If the rubber hose is found to be aging, it should be updated in time to avoid accidents. Then when choosing rubber hoses, it is suggested to choose metal bellows with long service life, so that the corresponding danger degree will be reduced and our safety will be guaranteed to a certain extent.

Gas explosion may also be caused by nonstandard use of liquefied petroleum gas tanks in restaurants. Families who use liquefied petroleum gas cylinders must use cylinders that can be traced back to the source, and the cylinders have corporate logo service telephones, and they should sign a gas contract with them, so that the gas source can be checked, and they can also be called to come to the door for service in case of failure. In case of danger, you can also negotiate with the gas company to find out the cause of the accident. This teaches us that when using liquefied petroleum gas tanks, they should be placed correctly, closed tightly after use, and cylinders must be used correctly and standardized.
