Gas accidents are very harmful
There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal-to-gas. At present, the main source of gas used in our city is natural gas, the main component of natural gas is methane, which is a colorless, tasteless, non-toxic, non-corrosive combustible gas, before the gas supply, the gas company will add a chemical substance called tetrahydrothiophene in accordance with the regulations, commonly known as "odorant", with an obvious rotten egg taste, users can identify whether the gas leaks through the sense of smell.
Gas leaks can cause carbon monoxide poisoning. When natural gas leaks or burns incompletely, it will produce toxic carbon monoxide gas, and the human body will inhale carbon monoxide to cause hypoxia, poisoning, and in severe cases, it will cause death to patients. When the concentration of natural gas leakage in the air reaches 5% to 15%, it will cause a flash explosion accident when it encounters an open flame or electric spark.
How to use gas safely
According to reports, the scrap period of gas cookers, gas water heaters, volumetric water heaters and heating stoves is 8 years, and it is strictly forbidden to use them beyond the time limit. When using gas appliances, someone should take care of them, and attention should be paid to the ventilation of the use environment; When you stop using gas, you should check that the switches on and off of the stove and water heater are turned off.
There are generally two kinds of household gas pipes, one is the hose, which is easy to age and cause risk factors such as fracture and gas leakage, so it is not recommended to use; The second is the metal bellows, which can be used for 6 to 8 years. When using gas pipes, pay attention to the length of the gas pipes, which should not exceed 2 meters. Do not place the gas pipe near the stove surface to avoid being grilled by the flame. Do not go through walls, doors and windows. Do not press or fold the pipeline, so as not to cause blockage and affect the continuous air supply. At the interface between the gas pipe, the gas appliance and the pipeline, please clamp the pipe tightly to prevent it from falling off and leaking. The replacement of metal bellows must be carried out by a professional.
When the pipe gas is completely burned, the amount of air that needs to be consumed is more than 4 times that of the gas, and the kitchen and gas appliances should be well ventilated.
Check the gas facility for air leaks, use a soft brush dipped in soapy water, and smear pipe connections or suspected air leaks. If bubbles bubble, there is a leak in the area. If the natural gas pipeline or gas facilities (pipeline behind the meter) in your home need to be changed, you need to go to the business hall of the natural gas company to go through the relevant procedures, and the gas company will send professionals to the door for construction and installation, and it is strictly forbidden to dismantle and change it privately.
