1, exposed to high temperature.
Flammable and explosive articles should be avoided in high temperature environment. Gas tanks are flammable and explosive, which are prone to explosion under long-term high temperature exposure.
2. Encounter an open flame.
When the valve of the gas tank is opened, a small amount of gas will be discharged into the air. When there is an open flame in the air, it will burn and explode after contact.
3. External violence.
When the outside of the gas tank is violently hit, the gas tank bottle will be deformed and the gas in the tank will be compressed, which will lead to the increase of the pressure of the gas tank bottle. When the bearing capacity of the tank bottle is exceeded, the gas may be ejected from the bottle and explode.
4. The gas tank has exceeded its service life.
When the service life of the gas tank exceeds the service life, the gas tank bottle will rust and the rubber tube of the gas tank will be worn and damaged. If it is not replaced in time, it is easy to explode.
The fuel tank is too full.
After the gas in the gas storage tank is overfilled, it is easy to expand and explode when it encounters high temperature or the temperature difference between inside and outside changes greatly.
Extended data:
Please do the following eight things when using gas safely:
1. Cylinders must be placed upright. When handling cylinders, be careful. Don't scald them with fire or boiling water. Don't expose them to the sun for a long time. Don't put them by the fire. When using bottled liquefied petroleum gas, it is strictly prohibited to use it with other fire sources such as coal stoves. It is forbidden to dump the residual liquid in the steel cylinder by yourself.
2. Before installing the pressure reducing valve, check the air inlet sealing ring. If it is deformed or falls off, it must be reconfigured and cannot be replaced by other accessories. Generally, the service life of pressure reducing valve is 5 years, and it should be checked regularly when in use. If it is invalid or expired, it should be replaced in time. It is forbidden to install the tee behind the pressure reducing valve. Do not dismantle and repair the angle valve and pressure reducing valve of the cylinder without authorization.
3. Pay attention to leak detection during use. Leak detection points include: cylinder angle valve, hose, joint between pressure reducing valve and cylinder angle valve, and joint between hose and pressure reducing valve and cooker.
4. Special oil-resistant rubber hose for gas should be used, and the length should be1.2m-2.0m. If aging cracks are found, it should be replaced in time, and the service life of rubber hose is 18 months. Don't seal the hose in the cupboard to avoid being bitten by rats. Gas hoses must not pass through walls, windows and doors.
5, the hole of the stove should always be cleaned with fine wire to avoid blocking tempering. If the gas appliance is seriously damaged or expired, it shall be updated in time.
6, the use of liquefied gas kitchen to maintain good ventilation; It is forbidden to install non-enclosed gas water heaters in toilets; It is forbidden to use bottled liquefied petroleum gas in bedrooms, basements and poorly ventilated rooms.
7. If you smell liquefaction in use, you should immediately close the cylinder angle valve, control the source, and check the cooker, hose and cylinder. If necessary, please call the service number of the gas supply unit for help in time. Don't use liquefied gas until the hidden danger of gas leakage is eliminated.
8. Before going out and going to bed at night, please check whether the stove switch and the cylinder angle valve (the plug valve behind the pipeline gas meter) are closed.
The safety of people's network-gas tank can not be ignored, and the following points should be done to prevent explosion.
