In winter, many families will choose to use gas water heaters. Because of their fast heating, large water output, stable temperature, and no water control, they are favored by many users. This may bring a problem, that is, carbon monoxide poisoning. This is not the case. A few days ago, two residents of a certain district of our city were rushed to the hospital because of improper use of gas water heaters. The reason was that they forgot to close the gas valve after use, which led to the accident.
Carbon monoxide is a product of incomplete combustion of carbonaceous materials. It is a colorless, odorless, odorless gas that is poisoned by inhalation through the respiratory tract. When using wood stoves and coal stoves, such as the ventilation system is not smooth, especially in recent years, improper use of gas heaters and gas water heaters has increased the number of cases of carbon monoxide poisoning.
In the investigation, the reporter found that many residents use gas water heaters in the winter bath. Aunt Aunt, who lives in Fengzeyuan Community, was surprised at the carbon monoxide poisoning caused by forgetting to close the gas valve. "It has been used for several years in gas water heaters, and I often forget to close the valves. I really don't know that there are potential safety hazards. I can pay more attention in the future!" said Aunt Aunt.
During the interview, many people thought that the gas water heater was easy to use and did not know that it would be dangerous because of the negligence of the moment. When the reporter mentioned that improper use of gas water heaters would produce carbon monoxide, many citizens immediately said that they must tell their families to use them correctly.
It is understood that every winter, the city's major hospitals will receive patients with carbon monoxide poisoning, light dizziness, fatigue, nausea and vomiting, severe cases will appear coma, and even death. To this end, the doctor reminded that in case of carbon monoxide poisoning, the patient should be transferred to a place with fresh air and dial 120 in time.
Then, what problems should be paid attention to when using gas water heaters? In addition to eliminating the inferior gas water heaters to buy home, how to use gas water heaters in daily use to ensure safety?
First, it works properly. When the user uses the gas water heater, first turn on the water heater valve to ignite, then open the cold water valve, and then open the hot water nozzle to supply hot water. After use, operate in the order of water stop-stop gas-turn off the ignition switch and close the gas main valve.
Second, keep ventilation. When people use gas water heaters, if they do not pay attention to ventilation, the indoor oxygen will be greatly reduced, resulting in incomplete combustion of the gas, resulting in a large amount of carbon monoxide, which may lead to carbon monoxide poisoning accidents.
Third, the use should not be too frequent. Do not use the gas water heater for more than 30 minutes at a time. If it is more than 5 minutes, it should be used continuously to avoid accidents caused by high frequency and overload of the gas water heater.
Fourth, pay attention to inspection and maintenance. Usually, soapy water or other foaming agent can be applied to the gas pipe connection. If there is air bubble, the pipe leaks and must be replaced in time. Every year, the after-sales service personnel should come to the door for a safety inspection, regularly clean the carbon deposits and dust on the heat exchanger sheets to ensure the smooth discharge of smoke.
Fifth, pay attention to antifreeze. When not used for a long time in winter, pay attention to drain the water to prevent the water heater from freezing and cracking.
Sixth, pay attention to the period of use. The life expectancy of gas water heaters is generally 6 to 8 years. Water heaters that have passed the service period will be replaced in time.
