Why does the family get poisoned?

Why do you bathe and wash, and your family is poisoned?

Professor Lu Min of the Institute said that the oxygen needed for the combustion of gas water heater comes from the room, and the waste gas generated is discharged out of the room through the flue. This kind of water heater will consume a lot of oxygen when burning. Many people install this kind of water heater in the bathroom, plus the bath time is too long, the area of the bath room is relatively small, and the oxygen is consumed in a short time, and people will have carbon monoxide poisoning Or hypoxia shock.

Ms. Liu's gas water heater and gas tank are placed in the living room. In addition, the air leakage at the connection between the water heater and gas tank increases the concentration of carbon monoxide in the room, which leads to carbon monoxide poisoning in the whole family.

Notes on bathing of gas water heater

Because some consumers have adopted incorrect installation and use methods, causing some safety accidents, which makes people sigh, but also makes the development of gas water heater cast a shadow. In order to let you enjoy the convenient and comfortable bath provided by the gas water heater, experts advise you how to use the gas water heater safely:

1. The gas water heater must be installed outside the bathroom (except for the balanced gas water heater), and the smoke exhaust pipe must be installed according to the national standard, so as to discharge the exhaust gas generated by the gas water heater to the outdoor during use, otherwise it may cause carbon monoxide poisoning accident.

2. When using the gas water heater, keep the room well ventilated.

3. When using the flue gas water heater, ensure that the indoor air and outdoor air can conduct natural convection.

4. The flue gas water heater shall be used carefully in windy weather. If it is found that there is air pouring into the room along the flue, do not use it.

5. The gas water heater shall be installed by the professional personnel designated by the manufacturer, and the professional maintenance personnel shall regularly clean the carbon and dust on the heat exchanger plate to ensure the smooth discharge of flue gas.

6. The direct exhaust type domestic gas water heater has been banned from production and sale by the state, but there are still some users who are still using it, which has potential safety hazards. Please pay attention to timely replacement and use the forced exhaust type gas water heater or the balanced type gas water heater.
