Mr. Wu said that the rubber hose of the stove has been used for two years, and it has been hard to touch. “Is the hose changed?” In the face of Mr. Wu’s question, the Municipal Safety Supervision Bureau suggested that rubber hoses are aging and too long, which are easy to cause safety hazards. The public must pay attention to it and strengthen self-inspection. It is best to use Dedicated metal bellows.

According to reports, due to the relatively high temperature of the kitchen, storage and other reasons, rubber hoses are easy to age, fall off, wear, easily bitten by rats, need to be checked frequently and replaced once a year. In addition, the use of rubber hoses must be installed with a pipe buckle, otherwise it will fall off easily, causing an accident. The hose should not be placed close to the burner to prevent high temperature damage. When not using gas, close the single-nozzle valve, that is, the rear valve, to keep the kitchen ventilated.

The relevant person in charge of the Municipal Safety Supervision Bureau said that although the price of rubber hose is relatively cheap, if the conditions permit, especially for the use of gas with more pests, the public should replace it with a metal corrugated hose. The hose has a longer service life and is less prone to aging than the rubber hose and is not easily bitten by the rat.

“It is recommended that the public can go to the gas company to purchase metal corrugated hoses made by regular manufacturers, and install them by gas company professionals. You can also install household gas alarms in the kitchen. When accidental air leaks occur, you will be alerted for the first time. To reduce the incidence of gas accidents." The relevant person in charge of the Municipal Safety Supervision Bureau said, "Citizens can also buy metal corrugated hoses on the market themselves, but they must be produced by regular manufacturers. Do not buy inferior products for greed, increase Security risks."

The reporter learned that in addition to asking professionals to go to the door for inspection, the public can also conduct self-inspection of gas appliances on a regular basis in daily life:

First smell smell, a special smell is added to the gas, and it is easy to be detected if it is leaked. Secondly, if the gas is not used at all, check whether the number in the red frame of the gas meter is moving. Finally, spray it with soapy water. At each interface, if a bubbling is found, there is a leak. (Wei Xin Li Chengshi)

Coal  and coke
Coal is a naturally-found fossil fuel that is formed by the anaerobic decay of plant life taking place over millions of years. The energy released when the fuel is burned comes from the initial solar energy that remains stored in the hydrocarbons contained in coal. Coke is what remains when the impurities in coal, such as coal-tar and coal-gas, are removed by high temperatures in an oxygen-free furnace. The absence of oxygen during the process prevents the coal from burning. Unlike coal, coke can be burned with little or no smoke.
