If the gas tank is on fire, we should face it calmly and call the fire department for help immediately. In the case that firefighters have not arrived yet, we should take corresponding fire-fighting measures as appropriate. Don't panic at the sight of the fire, hurry or run away, which will only cause greater losses. Let's take a concrete look at how long the service life of gas tanks is.

The official name of the gas cylinder is "liquefied petroleum gas cylinder". "Gas cylinder" is a kind of special equipment, which is managed by the state. The state has special laws and regulations on the management of gas cylinders, covering eight links such as design, manufacture, filling, transportation, storage, distribution, use and inspection of gas cylinders. Whether the waste "gas cylinder" can be filled with gas mainly depends on whether it exceeds the designed service life and whether it is within the validity period of inspection. The design service life of "gas cylinders" manufactured before 2007 is not marked, and its service life is 15 years, which is inspected once every four years and terminated after the last inspection.

The design service life of gas cylinders manufactured after 2007 is marked on the bottle body, and the standard design is 8 years. It can be used for 8 years, and it can be used for up to 4 years after passing the evaluation, which means it can be used for up to 12 years. So sometimes the cylinders that leave the factory first are not scrapped, and the cylinders that leave the factory later are scrapped first. This is the implementation of manufacturing standards. "Gas cylinders" that have reached the designed service life or "gas cylinders" that fail to pass the inspection shall be destructively treated by inspection and testing institutions, and the treatment method is generally flattening or sawing.
