With the continuous improvement of living standards, household gas appliances are widely used because of their advantages such as convenient use, high efficiency, and environmental protection. However, due to the uneven production technology, gas cookers have some potential safety hazards.
According to a report by Beijing Youth Daily, the AQSIQ announced the results of the quality inspection of gas stove products on the market. The main problems found in spot checks for unqualified products were gas leaks in the gas pipeline system, such as the Opel brand. JZ20Y.2-988" model gas stove; In addition, some products in the flue gas carbon monoxide content exceeded, such as Ge Bang brand "JZY2-226AX" model products, which may lead to carbon monoxide poisoning users.
Carbon monoxide is the main ingredient in what we know as the so-called "gas." This gas is a colorless, odorless, odorless, non-irritating toxic gas. Carbon monoxide has a long life in the atmosphere and can stay in the atmosphere for 2-3 years. Therefore, this is a kind of accumulation of atmospheric pollutants.
Carbon monoxide mixed in the atmosphere is a poison harmful to blood and nerves. It enters the body with the air, enters the blood circulation through the alveoli, and can form reversible binding with hemoglobin in the cells, myoglobin outside the blood, and cellular respiratory enzymes containing divalent iron.
As we all know, oxygen is an indispensable element of human life, but the affinity of carbon monoxide and hemoglobin is 200-300 times greater than that of oxygen and hemoglobin. When carbon monoxide enters the human body, it not only reduces the oxygen-carrying capacity of the red blood cells to cause hypoxemia, but also slows down and inhibits the resolution of oxygen and hemoglobin and the release of oxygen, resulting in hypoxia. Under hypoxic conditions, cerebral vasospasm occurs first in the central nervous system, which is most sensitive to hypoxia, and cerebral edema occurs in severe cases, followed by cerebrovascular disease, resulting in focal softening and necrosis of a certain part of the brain. High concentrations of carbon monoxide caused by acute poisoning, poisoning, weak pulse, slow breathing, and finally failure to death. according to
The experts explained that cardiovascular patients who live in a low concentration of carbon monoxide for a long period of time can contribute to the deterioration of the condition and cause blood lipids and cholesterol to deposit in the blood vessels. Chronic carbon monoxide poisoning causes neurological symptoms such as headaches, dizziness, and decreased memory and other symptoms of neurasthenia. In the epidemiological survey, it was found that observation of smoking and non-smoking pregnant women, pregnant women who smoked pregnant women had a tendency of low body weight and mental retardation.
Therefore, in order to protect the safety of users, experts pointed out that when selecting gas stoves, in addition to the selection of product types, products with high requirements for safety performance of gas stoves should be carefully selected in terms of quality:
The first is the purchase of products produced by production license manufacturers. At present, the production of domestic gas cookers adopts a production license system. Therefore, when purchasing, you must clearly identify the production license number and the name, address, and quality certificate of the product. It is recommended that consumers go to regular shopping malls or specialty stores to buy brands with a certain reputation and products with good after-sales service protection.
The second is to observe the appearance of the gas stove. Some paint products made of cast iron, steel plate and other materials should be evenly painted without blistering or shedding. The overall structure of the gas stove should be stable and reliable, the stove surface should be smooth and flat, no obvious warpage, and the installation of the components should be solid and reliable, and there should be no loosening phenomenon.
The third is trial. The installation position of the gas stove's switch knobs, nozzles, and ignition devices must be correct. When the ventilation is ignited, the gas should be ignited and ignited on almost every ignition (starting 10 times at least 8 times to ignite the flame), 4 seconds after ignition. The internal flame should be burned all over the fire hole. When the electronic igniter is used to ignite the human body, when touching the metal parts of the burner, there is no electric shock. When the flame is burned, it should be uniformly stable and blue-blue, with no yellow fire or red fire.
Fourth, the installation and maintenance of stoves must be carried out by professionals who have been trained by the manufacturer or their designated after-sales service units and who have obtained installation qualifications.
In addition, experts also remind consumers to regularly inspect cookers, pipes, cabinets, etc. It is recommended that the carbon deposition of a burning appliance should be cleared in about half a year to check whether the gas hose is aging. Pay attention to the period of use, under normal circumstances, the use of gas cookers for a period of 8 years, if there is leakage, leakage, deterioration of combustion conditions and other failures should also be scrapped in time to eliminate security risks, so as not to cause disaster.
At the same time, consumers should regularly clean the surface of the gas stove, including the burner head, according to the instructions in the manual, and adjust the damper located at the bottom of the product in time according to the instructions to ensure that the gas is fully burned to produce as little carbon monoxide as possible to protect the consumer's body. health
