Indoor carbon monoxide sources

1. Stove
Stove is a cooking appliance for daily life. In the case of gas stoves, gas combustion requires sufficient oxygen. However, when indoor ventilation is not smooth, the gas cannot be fully burned, and carbon monoxide is easily produced. If the doors and windows are closed in winter, and the gas stove is used to boil water for cooking, the air circulation is blocked, and the gas is not fully burned in a limited space, and carbon monoxide is quietly generated.

2. Fireplace
Fireplace has both heating and decorative effects in the room. When wood is used as fuel, if the fireplace is not well designed or the chimney is not well drained, the wood cannot be completely burned, and carbon monoxide will accumulate indoors. The common situation is that the chimney is blocked, so that the exhaust gas generated by combustion cannot be discharged smoothly, and the carbon monoxide is then trapped in the house, endangering the health of the residents.

3. Water heaters
Water heaters are equipment that provide domestic hot water. If gas water heaters are improperly installed, such as installed in a closed and narrow space without good ventilation, the carbon monoxide generated by gas combustion during use is difficult to discharge outdoors and can easily accumulate indoors. Some old water heaters, due to long service life, aging components, and reduced combustion efficiency, will also increase the risk of carbon monoxide generation.

Fourth, motor vehicles
Although motor vehicles are mainly active outdoors, if the garage is connected to the living room and the garage is poorly ventilated, the exhaust gas discharged after the motor vehicle is started contains carbon monoxide, which may seep into the room. For example, if the owner starts the vehicle in the garage and does not open the garage door for ventilation in time, carbon monoxide will flow into the room with the air, causing harm to indoor personnel.
