    There will be gas leaks, **, gas poisoning and other problems. Coal gas is also known as gas, liquefied petroleum gas, and liquefied natural gas. Gas is a colorless, odorless, odorless gas, but the gas we use has a pungent smell, which is artificially added to prevent gas leakage when people are alert to find, the permeability of gas is twice that of air, insoluble in water, does not support combustion and can not maintain breathing, when it reaches a certain concentration, it can make people suffocate due to lack of oxygen, and can burn or **.

    Gas exists in the coal body or surrounding rock in a free state and an absorption state. The main components of the gas we use daily are alkanes, of which methane accounts for the vast majority, and a small amount of ethane, propane and butane, in addition to hydrogen sulfide, carbon dioxide, nitrogen and water vapor, as well as trace amounts of noble gases, such as helium and argon. Under standard conditions, methane to butane exists in a gaseous state, and pentane above is a liquid.

    In case of open flame, it can be burned, and "gas" will occur, which directly threatens people's lives.

    Using a gas canister can can be dangerous, but don't worry too much. In the event of an accidental gas leak, do not start any electrical equipment, including lights, exhaust fans, range hoods, TVs, radios, etc., open doors and windows in time for ventilation, and report to the gas company quickly.

    The use of gas canisters is a matter of careitem

    1. Gas appliances should be qualified products from regular manufacturers, and they should not be greedy for a temporary cheapness and bury hidden dangers of accidents.

    2. When installing a gas water heater, be sure to ask a professional team to standardize the installation, and when using the water heater, be sure to keep the indoor ventilation well.

    3 When using gas, be sure to have someone watch over the stove. Check whether the gas valve is closed every day before going out and going to bed.

    4. When carrying out interior decoration, do not move the gas facilities, do not install the gas meter, gas pipe, etc. in the cupboard, and do not seal the gas valve.

    5. The gas cooker should not be placed directly below the gas meter, and must be staggered more than 30 cm below the gas meter, so that the gas meter should not be heated or damp.

    Because there is no fuel to replace gas. It's a bit one-sided to say that gas is dangerous. It is still very safe to use gas under normal operation.

    Therefore, it is necessary to learn the common sense of using gas. Install gas alarms. It is very safe to operate normally.

    Therefore, you must not be careless when using gas.

    Canned gas is very safe, because canned gas is well sealed, so it is very safe, not easy to leak, if you don't use high temperature, don't use high temperature, he will generally be very safe, as long as it is properly kept, it will be safe, because the canned gas is well sealed. And the outer packaging is strong, so it is very safe, very safe, and there is no need to worry about this.

    Specifications for the use of gas cylinders1. When configuring liquefied gas tanks and their accessories, families must purchase products that comply with relevant national regulations.

    2. The gas tank provided by the filling unit that has obtained the filling license must be used.

    3. The gas tank should be placed in a cool place, avoid moisture, and the stove and heating should be separated by not less than 1 meter, it is strictly forbidden to roast or soak in hot water, sun or invert use, the angle valve should be closed when moving the gas tank, and it is strictly forbidden to hit, stack and roll when handling.

    4. The liquefied gas tank must not be placed horizontally, poured the residual liquid by itself, and shaken violently.

    MostlyGas canistersIt is easy to carry and can be used in different places, such as barbecue restaurantsFood stalls, picnics, BBQ, etc. can be used.

    The gas tank should be stamped with an inspection date mark, and if the service life exceeds 15 years, it should be scrapped. Always check the gas tank and the switch and pipe of the gas stove to check whether there is any gas leakage.

    The gas tank at home should not be close to the heat source, open flame, exposed to the sun, heated by fire, hot water, etc., and should not be upside down. When the gas of the gas tank leaks, it cannot be dumped to avoid the danger of occurring.

    In case of gas leakage or pipe fire, cover your mouth and nose with a wet towel before entering the room, then cover the burning area with another wet towel or soaked quilt, then close the valve, open the doors and windows for ventilation, and then put the tank in a safe place. If you can't get close to the gas tank, use cold water to lower the temperature of the tank to prevent the gas tank from being grilled by a flame**.

    Precautions for the use of gas canisters

    When using, you should first unscrew the door on the top of the bottle, and then unscrew the switch on the stove. When closing, the switch on the tank should be turned off before turning off the switch on the stove. You can't just close one valve.

    After cooking, before going to bed and going out, the stove must be double-checked to make sure that the valve on the gas tank is closed.

    Gas canisters should be inspected daily and should not be ignored! For the pipe joints used to connect the gas stove and the gas tank, soapy water should be smeared frequently to check whether there is gas leakage, and the gas leakage should be repaired in time. In addition, the length of the connected hose should be kept between m and 2 m, the two ends of the hose must be tightened with clips, and the aging or damaged hose should be replaced in time.

    If used carelessly, it can lead to gas poisoning.

    or fire accidents, threatening personal safety.

    This is because natural gas, a substitute for gas tanks, does not fully cover populated areas, and the cost of natural gas is relatively high. The details are as follows:

    1) Natural gas does not completely cover population areas:

    Not all places have piped natural gas, especially in some rental houses, and you must use it for your own life. Nowadays, many rural areas also use gas tanks when there is no natural gas, and when they are not in use, they can turn off the gas tank valve.

    2) The cost of Tian Li is relatively high:

    Urban rent, gas, heating, and household appliances are important factors for tenants to choose a house, especially those who like to cook, but the convenience of natural gas cannot hide the high cost of natural gas equipment.

    Reasons for frequent gas tank accidents:

    1. During the use of liquefied gas cylinders, they must go to the cylinder testing station approved by the labor department for regular inspection and maintenance. However, only a few state-owned gas filling companies can truly fulfill the regulations, and the vast majority of individual filling stations (points) do not act in accordance with the regulations.

    2. The reason for the lack of cylinder inspection is that in addition to the individual filling station (point) for the benefit and disregard for the user's safety, there is also a considerable part of the reason from the user itself. Mainly manifested in:

    1) There is no problem of opening an account for gas cylinders. Most of the people who come to inflate are some users who are greedy for convenience and ignore safety issues, and some of these users are not only local residents, but also some of them are outsiders, and some of them are ignorant of the common sense that cylinders need to be tested regularly.

    2) The life of the cylinder is shortened due to the harsh use environment. Wet areas such as migrant workers' sheds and food stalls at construction sites are easy to cause the cylinders to rust and peel off, resulting in the reduction of the wall thickness of the cylinders.

    3) Some users know that the testing time limit has arrived, but they give up the test because of the trouble of sending it for testing, etc.

    The existence of the above problems has led to the flow of a large number of unqualified or overdue cylinders into thousands of households, which has planted a "time bomb" in the homes of the general public and has become a major safety hazard in the city.

    There is a danger, and there is a certain danger when the gas is not used and stored for too long. Because the gas tank may leak if not used for a long time, and because there will be some common fire sources at home, such as lighters, matches, etc., long-term storage will increase the risk of contact with the fire source.

    It's easy to use, and as long as you follow the rules of use and regularly inspect it (pressure reducing valves, connecting hoses, etc.), there will be no problems.

    Generally, our family commonly used for 15 kg of gas tank, it is normally allowed to fill the maximum amount of kilograms, if the overfilling, that is, greater than kilograms, first of all, the internal pressure itself will be relatively large, secondly, the liquid gas filled inside, in the normal gasification process, the volume will increase, so that the pressure will rise.

    When the internal pressure is too large and exceeds the pressure that the cylinder can bear, the steel pipe will be mechanical, and the leaked flammable liquid will also quickly vaporize and expand in volume, and serious accidents will occur when encountering open flames. Therefore, in the case of overfilling of gas tanks, it may occur even if the gas tanks are used normally**.

    Encyclopedia of safety knowledge about the use of gas tanks:

    1. Pay attention to the inspection date mark on the protective cover of the gas cylinder, and resolutely abandon it if the use date is more than 15 years.

    2. Always check whether there is gas leakage in the gas tank, gas stove switch and pipeline.

    3. The gas tank should not be close to the heat source, open flame, exposed to the sun, heated by fire, hot water, etc., and the gas in the gas cylinder should not be poured into other gas cylinders, and it is strictly forbidden to dispose of the residual liquid in the gas cylinder by yourself.
