With the development of the city, some of the new residential buildings are installed with piped gas, due to the lack of safety knowledge of some users, and thus in the process of using the gas is often due to incorrect method of leaving the accident hidden danger. To this end, to remind the majority of users, the use of piped gas do not ignore the safety. First of all, to choose the nature of the qualified gas stove, is strictly prohibited with the liquefied stove interchangeable use; second is not stacked near the stove flammable and explosive substances; third is the use of the process should be frequently observed combustion to prevent gas leakage; fourth is the use of the valve should be closed first connected to the hose, and then close the stove valve; fifth, such as the use of gas water heaters should be selected to obtain a national production license of the product, the installation of water heaters in the room should be well ventilated and add smoke. The room where the water heater is installed should be well ventilated with a flue, and it is strictly prohibited to install the water heater in the bathroom to avoid gas leakage and poisoning. In case of gas leakage in the process of using gas, you should stop the open flame or use all kinds of electrical switches, and at the same time, you should immediately open the doors and windows to ventilate the room, and quickly report to the gas company for repair. Before the arrival of repairmen, the following emergency measures can be taken: firstly, close the main valve, soapy water can be used to smear the leakage checking, the blistering place is the leakage point, and it is strictly prohibited to pick up the leakage with an open flame. If the leak is under the table and before the valve, you can use wet cloth to tightly tie the leakage pipe, waiting for the gas company personnel to come to repair.
How to use the gas tank safely and what matters should be noted
The safety operation procedure of the gas stove
A. The gas stove and gas tank are managed by a person who can check the status of use every day.
These are the first time I've ever seen a gas stove in my life, and I've never seen a gas stove in my life that I didn't want to.
Three, every day when you open the gas carefully check whether the gas leakage, each cut-off parts are safe and reliable. Replacement of gas canisters must be connected to the connector.
Fourth, to ensure that the pots and pans stove surface equipment clean and sanitary.
V. Operators are familiar with the operating equipment and environmental facilities after training before operation.
6, the gas stove before the cooking operator neatly dressed shoes and hats, the operation of the use of the process to pay attention to the safety, be careful to heat the cooking oil escape scalded.
7, equipment abnormalities in a timely manner to the leadership to report, to find professionals to repair.
eight, every day after the use of gas tank equipment closed the total gas shutter, after checking that all closed intact, to confirm that there is no leakage and other anomalies, lock the gas tank room.
When cleaning the gas stove equipment, completely cut off the gas source and power supply.
Gas tank
Now home life often use to liquid gas, we commonly known as the gas tank is loaded with liquid gas a vessel.
The gas canister is a steel mobile pressure vessel with an explosion hazard, and its wall thickness is only about 2.5 millimeters (the wall thickness of the new cylinders is calibrated at the factory), which is a very good book, and it is always subjected to the pressure from the internal medium. ~ 12 kg force / square centimeter), the entire cross-section to withstand about 1000 kg of tension.
"Gas tank" in the long-term filling, transportation, use of the process of collision, exposure, medium corrosion damage, will produce fatigue cracks, craters, deformation, corrosion thinning and other defects, these defects are the direct cause of the explosion. You have seen the "gas tank" explosion scene?
"Gas tank" explosion, instantly produce two damage, the beginning of the tank rupture physical explosion, liquid petroleum gas instantly expand 250 to 300 times into a gaseous state, resulting in shock waves, like a landmine explosion. Become gaseous LPG quickly mixed with air, when the concentration in the air down to 3 ~ 11%, such as open flame, will produce a chemical explosion, the entire gas space explosion and combustion, resulting in a huge shockwave, injury to life, burned property, destruction of buildings, bringing about a second catastrophe, the people if you inhale this explosive gas will make the respiratory tract and lungs burned tissues, terrible to the extreme.
From the protection of people's lives, the State Council promulgated the "Regulations on the Safety Supervision of Special Equipment" will be the liquefied petroleum gas cylinders as statutory monitoring equipment. "Gas tank" is not a permanent durable goods, professional and technical personnel after a large number of accidents and analysis of scientific tests, measured "gas tank" safety period of only 15 years, during this period every 4 years, but also a periodic inspection, in order to find out the existence of defects, this is the best way for you and your family. This is to ensure the safety of you and your family, but also the "gas cylinder safety technology supervision regulations".
The current market price of LPG cylinders in the sale of about 100 yuan, less than a shirt money, you do not want to skimp, can not afford to update it, overdue for service, leaving the disaster at home. Remind you again, buy "gas canisters" to a fixed store, do not go to the free market to buy, where there are many shoddy goods, do not support the bottom.
You out of the cylinder should not be sold as ordinary scrap metal, and do not dispose of your own, so that accidents are prone to occur, the cylinder should be sent to the local Quality and Technical Supervision Bureau or boiler pressure vessel inspection center to do destructive treatment, otherwise, fall into the hands of others, may be refurbished, and then into the market to victimize others.
If you have any questions about the safety of your gas tank, please contact the Quality and Technical Supervision Bureau, which is responsible for monitoring gas cylinders.
How to use natural gas safely and correctly

If you encounter a malfunction, call the manufacturer's maintenance number or the gas supply unit's phone number labeled on the alarm.
How to use gas safely
Natural gas is a mixture of all naturally occurring gases in nature. It is a flammable gas contained in the earth's layers, and its main components are methane, ethane and other gaseous hydrocarbons.
Natural gas is flammable and explosive and air mixture, the temperature reaches about 550 ℃ will burn; the concentration of the mixture reaches 5% -15%, will explode when encountering fire. Natural gas has a high calorific value of about 8500-10000 kcal/m3, and the heat emitted by natural gas combustion is about 2.5 times that of city gas of the same volume.
Currently the main uses of natural gas:
Natural gas can be mainly used for power generation, natural gas-fueled gas turbine power plant waste emission levels are much lower than the coal-fired and oil-fired power plants, and power generation efficiency, low construction costs, construction speed; in addition, the gas turbine start-stop speed, strong peak shifting capacity, less water consumption, occupies a provincial.
Natural gas can also be used as a chemical raw material. Natural gas as raw material for the primary processing products are mainly ammonia, methanol, carbon black and other nearly 20 varieties, after secondary or tertiary processing of important chemical products, including formaldehyde, acetic acid, dimethyl carbonate and other more than 50 varieties. With natural gas as raw material, the chemical production unit has low investment, low energy consumption, less land occupation, less personnel, good environmental protection and low operating costs.
Natural gas is widely used in civil and commercial gas stoves, water heaters, heating and refrigeration, but also for paper, metallurgy, quarrying, ceramics, glass and other industries, but also for waste incineration and drying and dehydration treatment.
Natural gas vehicle carbon monoxide, nitrogen oxides and hydrocarbon emissions levels are much lower than gasoline, diesel engine cars, no carbon buildup, no wear and tear, low operating costs, is a kind of environmentally friendly cars.
Notes on the use of natural gas:
1. Why must the place where gas is used be well ventilated?
The use of gas (natural gas, artificial gas, liquefied petroleum gas) stoves and water heaters must be well ventilated, this is because the gas combustion to consume oxygen in the air to fuel combustion, while producing carbon dioxide and a small amount of carbon monoxide containing smoke, such as 1m3 of natural gas combustion to consume 10m3 of oxygen in the air, while producing 1m3 of carbon dioxide and 2m3 of water vapor. Water vapor. If the indoor ventilation is poor, the oxygen content in the indoor air is gradually reduced, insufficient oxygen supply will lead to incomplete combustion, and incomplete combustion will produce a large number of toxic gases of carbon monoxide, which will cause poisoning, oxygen deprivation and asphyxiation. Therefore, the use of gas must be well ventilated, so that the fresh air to be supplemented in a timely manner, and the smoke will be discharged to the outdoors at any time, so as to prevent asphyxiation or carbon monoxide poisoning, to protect the safety and health of the whole family.

How to safely use liquefied petroleum gas tanks
Now, the city has more than 1.2 million residents in the use of canned liquefied petroleum gas, which seems to be an ordinary liquefied petroleum gas tanks in fact, the use of a great deal of learning. First, learn to replace the pressure reducer. Check whether the seal on the pressure reducer is lost, but also note that the pressure reducer and the angle valve for the anti-buckling connection (i.e., anti-clockwise rotation), remember to install do not screw the reverse. After installation, shake the body of the pressure reducer by hand, such as swinging will need to be reinstalled. Second, to learn to test the leak. You can often use soapy water to brush the hose, the interface, the pressure reducing valve and hose parts of the connection, check whether there is no leakage. Third, learn to ignite. Ignition of this step is very critical, if more than two times did not light the fire, you should immediately stop the fire. Because then there will be liquefied petroleum gas leakage, to stop for more than two minutes to wait for the leakage of gas to dissipate, and then try to ignite the second time. Never remember not to open the exhaust fan, if this time to open the exhaust fan, the air filled with a high concentration of mixed gases, encountered in the fire will explode. Fourth, learn to adjust the wind. In the process of using liquefied petroleum gas, if you find pots and pans are blackened, or found that the fire went out, the flame red, yellow, this time the ratio of liquefied petroleum gas and air may be inappropriate, you need to adjust the dampers, the dampers adjusted to normal, so that the flame formed blue. Fifth, once the fire accident you do not panic, should be soaked towel immediately the cylinder angle valve shutter, and the cylinder will be transferred to outdoor open space to prevent the explosion. In addition, liquefied petroleum gas tanks can not be exposed to the sun, can not be privately dismantled, and can not be inverted and placed horizontally, pouring hot water and other methods to heat the cylinder is also not desirable. Strong sunlight will lead to the explosion of liquefied petroleum gas tanks. Pressure-reducing valve use period of five years, hose seals use period of three years, once old to update immediately.
How to use electricity and gas safely at home?

First Aid for Gas Poisoning
Wherever there is an open flame burning place, if it is closed or poorly ventilated, the concentration of carbon monoxide (CO) in the air can increase dramatically due to incomplete combustion, and people will be poisoned by acute CO poisoning after inhalation in a short period of time. The gas contains CO10% ~ 40%, gas poisoning is actually CO poisoning. CO can be combined with hemoglobin to become carboxyhemoglobin, hindering the red blood cells with oxygen, oxygen transfer function, the basic lesion of CO poisoning is hypoxia, the main manifestation is the brain due to lack of oxygen and coma.
