When we use the gas water heater, we must open the window for ventilation. Although the gas water heater is faster and has better effect, we must pay attention to the ventilation in the closed house when using it, because the gas water heater is likely to leak air when using it. Once this problem occurs, and you are in a closed environment, you will only face death, except using gas water heaters. In some rural areas, coal is used for heating. If these coals are not ventilated in time, they will also cause carbon monoxide poisoning. Many elderly people in rural areas do not pay attention to this problem, so many people in rural areas are poisoned by carbon monoxide.
If people around you encounter carbon monoxide poisoning, you must open the window for ventilation before saving people, and never turn on the light or ignite before saving people, because if the concentration of carbon monoxide reaches a certain level, it will explode because of a spark. As daily knowledge, children should know the harm of carbon monoxide to people's health from an early age and how to deal with carbon monoxide poisoning in their families. Only by letting children know this kind of problem from an early age will this kind of thing not happen again.
