11 items of gas safety knowledge are as follows:

1. In order to ensure that gas users can get standardized and safe service, please buy liquefied petroleum gas from regular gas enterprises and put an end to the use of "black gas".

second, when using gas, please keep good ventilation with the outdoor. If the ventilation is not smooth and the liquefied petroleum gas is not fully burned, it will produce toxic gases such as carbon monoxide. Carbon monoxide is colorless, odorless and imperceptible, and it is very easy to be poisoned or even die after inhalation.

3. Don't use gas appliances when the site is unattended, so as to prevent the soup from overflowing and dousing the fire, causing gas leakage and easily causing deflagration accidents.

4. Turn off the gas stove switch and cylinder angle valve in time after each use of gas, so as to prevent accidents, and "keep people away, put out the fire and keep the valves tightly closed".

5. Please use an oil-resistant hose of liquefied petroleum gas, the length of which shall not exceed 2m, the service time shall not exceed two years, and there shall be no aging and damage. The joints between the hose and pressure reducing valve, gas stove and water heater must be fixed with pipe clamps, and stainless steel corrugated pipes are recommended.

6. When using liquefied petroleum gas, do not pour the residual liquid by yourself. It is forbidden to expose the cylinder to the sun or close to the fire source, and do not heat it with boiling water or other methods to avoid accidents.

7. Please don't use inferior and outdated pressure reducing valves. Most of the illegally produced pressure reducing valves are unstable in pressure regulation, which easily damages gas appliances and leads to leakage accidents. When the pressure reducing valve is used for an extended period, the rubber sealing ring is easy to age and leak, which may lead to an explosion accident. The service life of the pressure reducing valve is 3 years. Please buy a pressure reducing valve with a production certificate.

8. Please don't use the gas stove and water heater for an extended period. The service life of liquefied petroleum gas water heaters and gas stoves is 8 years, and they must be replaced in time after this period.

9. Do a good job of daily leak detection, focusing on the joint between the hose and the cooker and steel cylinder. The common method is to smear soapy water, and it is forbidden to use naked flame for inspection.

11. Don't panic when you find gas leakage (abnormal odor), and you must remember four points:

1. Turn off the angle valve of the cylinder immediately.

2. Gently open the doors and windows for ventilation, so that the leaked gas can be released to the outside.

3. Don't switch on or off electrical appliances, bring in ignition sources and strike a fire. Do not use the doorbell if you find a leak in your neighbor's house.

4. You should call the gas company for help outdoors. It is forbidden to call at the scene of gas leakage.
