From:Beijing Municipal Commission of Health and Family Planning


The temperature is getting low in recent days. Many people living in buildings think that they do not need to worry about carbon monoxide poisoning caused by coal-fired heating. In fact, carbon monoxide poisoning accidents caused by household gas water heaters are commonplace nowadays.

Domestic gas water heaters produce nitrogen oxides, carbon monoxide, aldehydes, carbon compounds, carbon dioxide, etc. If the bathroom is poorly ventilated, the concentration of harmful gases increases. The burning consumes too much oxygen, which may lead to oxygen deficit. Inadequate combustion of gas will produce more carbon monoxide, giving rise to poisoning.

It is suggested to conduct regular maintenance of stoves, water heaters. Combustion devices should be installed outside the bathroom with inlet and outlet. While taking a bath, keep the windows and doors open a little to make the air circulated. When you finish the bath, you are advised to close the water heater. Do not bath for a long time. If symptoms like dizziness, headache, tinnitus, nausea and vomiting, palpitation appears, you should immediately stop bathing, open the door to let the fresh air in, call for help before losing consciousness.

If you find the patient in coma, he or she should be transferred out of the poisoning environment and lie on the ground. It is advised to do CPR to the patient and promptly call 120 for professional treatment.
