The water heater is a must-have bathroom appliance for every family. The hot water in the home is in use for a long time, but there are still many people who feel that they have not encountered any problems with the electric water heater and the gas water heater, so they will use it. I don’t know if there are many Security risks.
According to incomplete statistics, the number of casualties caused by various accidents of water heaters in China is more than 1,000 per year.
Since the gas water heater is a special type of safety product, the fuel (gas) used is a flammable and explosive gas. If there is a leak, when it reaches a certain amount, it will encounter an open flame (such as the gas stove of the kitchen, The spark generated by the start-up of electrical equipment such as electric smoke lamps and refrigerators can cause deflagration or explosion, which may lead to accidents such as fires. When using gas water heaters, a large amount of exhaust gas should be excluded. In addition to carbon dioxide, there is carbon monoxide. If you use it slightly, you will have a poisoning accident. Since there are no protection devices for gas leakage in general buildings, once the fault occurs, the consequences are often It is catastrophic, and instances of personal injury or death caused by gas poisoning are also common.
Therefore, Nanyang Fire Protection reminds the general public that while using gas water heaters, they should pay attention to the following items:
1. When using a rubber hose to connect the water heater, you should pay attention to check whether the rubber tube has cracks. It is best to replace it once every two years. You can use soapy water to check the presence or absence of air bubbles at the hose connection to judge whether there is any air leakage. Stop the leak.
2, because the gas has an odor, when there is such a taste, it indicates that there is a gas leakage phenomenon, do not start any electrical equipment at this time, open the doors and windows in time, close the gas main valve, check the leak point, if you can not solve it, you can Find the relevant service department to resolve it as soon as possible.
3, gas water heater product manual has a very detailed installation, instructions for use, should be read carefully, use correctly, to ensure safety, the valve can not be adjusted by themselves, not free to modify.
4. It is necessary to install a smoke exhaust pipe. After the gas is safely burned, carbon dioxide and water vapor are theoretically produced, but in fact, a trace amount of carbon monoxide is still generated. Carbon monoxide is a toxic gas. In normal combustion, the amount of carbon monoxide generated in the flue gas is very small, only about 0.1%, and then diluted in the atmosphere, its content will be very low, and will not cause harm to the human body. However, when the concentration reaches a certain level, it will cause poisoning, light dizziness, vomiting, and severe death.
5. When the gas water heater is used, the upper part emits black smoke, indicating that the heat exchanger has been seriously blocked or there is foreign matter in the burner, and should be immediately deactivated and sent for maintenance. During operation, it is found that the flame overflows from the outer casing or there is a flame in the lower part, which should be suspended.
