Safe use of "gas" to prevent not "burning"

What is natural gas?

The natural gas used in our daily life is mainly composed of methane, which is a colorless, odorless, non-toxic and non-corrosive flammable gas. So when using natural gas, we need to pay extra attention.

What about a gas fire?

1. If the gas tank is on fire, call 119 and evacuate the house quickly.

2. When the gas tank is heated for a short time, the valve of the gas tank should be immediately closed and the power supply should be cut off in time.

3. If the gas tank is on fire for a long time or there is an open flame, remember not to close the valve or pour out with cold water! It could cause an explosion!

4. In this case, you should immediately flee to a safe place and wait for firefighters to come and deal with the burning gas tank.

5. When the fire brigade deals with it, the gas tank should also be evenly cooled before being put out.

6. Do not dump the burning gas tank on the ground! Because when the gas tank is upright, no matter whether it is equipped with a pressure reducing valve, there will generally be no explosion, and the gas (liquid) in the horizontal gas tank will flow out through the mouth of the bottle, and it is easy to explode.

Natural gas safety precautions

One, one on, three off.

After using gas, the stove switch and the stove front valve should be closed to prevent gas leakage. If you go out for a long time, you need to close the table front valve.

Second, when using gas, people should not stay away.

In the process of using the stove, people can not stay away from it to prevent gas leakage caused by boiling soup overflow or wind blowing.

Third, often check whether the hose connection is fixed with clips and whether the hose is aging and cracking.

In daily use, it is necessary to pay attention to inspection and timely repair to prevent gas stoves from leaking. The parts that are very easy to leak are: gas meter housing, various connection points on the gas pipeline, gas nozzle cock, rubber hose, etc. When the gas leakage reaches a certain concentration, it will explode when it encounters an open flame.

Fourth, long-term use of gas must pay attention to ventilation.

If you use gas for a long time, you must pay attention to ventilation. If the kitchen is not well ventilated, there will be insufficient oxygen in the kitchen after the use of gas stoves, which is easy to cause carbon monoxide poisoning. It is understood that a binocular gas stove, if installed in a kitchen with a volume of less than 6 cubic meters, should change air no less than 5 times per hour. It is best to install exhaust fans in the kitchen to make air circulation.

Fifth, immediately open the doors and Windows, and timely call the gas company telephone repair.

If you find that there is a smell near the gas stove, be sure to open the window immediately, and call the police in a safe area in time. At the same time, it is strictly prohibited to enter the room with all kinds of fire, and it is not allowed to switch on and off the light, smoke and make phone calls on the spot, so as to prevent gas explosion.

Six, we must use gas appliances that meet national standards, and it is strictly prohibited to use infrared stoves.

Gas appliances that meet national standards should be used, and infrared stoves are strictly prohibited. Infrared stoves will produce harmful gases due to inadequate combustion, which is easy to cause indoor poisoning.

7. Check the gas hose regularly and replace it in time when it expires.

The hose should be replaced every 18 months to prevent cracking, aging or hard and brittle; Check regularly to prevent rat bites; The hose should not exceed 2 meters, and both ends should be clamped tightly with pipe hoops; The hose can not be higher than the stove, so as not to be baked by the fire and cause accidents.

Ten inaccuracies of Gas Safety

1. Do not use multiple air sources in the kitchen. Users who use piped gas are strictly prohibited from using bottled liquefied gas or raw briquette fire in the kitchen.

2. Do not stack inflammable and explosive items in the kitchen to prevent fire and explosion accidents.

3. Do not tie ropes, wires or hang items on gas facilities, and do not set off firecrackers around gas facilities.

4. Gas users are not allowed to add, change, move or install gas facilities and gas metering instruments without authorization.

5. Do not occupy pressure or cover gas pipeline facilities.

6. Rooms equipped with gas pipelines and gas appliances are not allowed to be converted into bedrooms, living rooms and toilets.

7. Gas pipelines, valves, gas appliances and other gas facilities are not allowed to be sealed or installed secretly.

8. It is not allowed to move, cover, alter, destroy or remove the safety warning signs of gas facilities without authorization.

9. No illegal use of gas facilities, embezzlement or diversion of gas.

10. It is not allowed to open or close the valve box and gas meter box without authorization and damage the gas facilities.

What about gas leaks?

Test: Apply with soapy water to the location of possible air leakage, foaming indicates air leakage.

Listen: Gas leakage will emit a slight "silk" sound, hear similar sounds to pay attention.
