DH receives carbon monoxide poisoning case and reminds public to ensure ventilation when using gas water heaters
The EMSD conducted a site investigation immediately and confirmed that there was no town gas leakage at the scene. The subject gas water heater is a model installed before the scheme for the Approval of Domestic Gas Appliances took effect in 2003, and therefore did not bear a “GU” mark. The investigation revealed serious corrosion at the flue of the gas water heater, which is believed to have caused the incident. The EMSD seized the gas water heater for further investigation.
Carbon monoxide is a colourless, odourless and tasteless gas that is a by-product of the incomplete combustion of any fuel containing carbon, such as wood, natural gas and gasoline. Exposure to a low concentration of carbon monoxide can lead to a range of symptoms, such as dizziness, headache, tiredness and nausea, whereas exposure to a high concentration of carbon monoxide can lead to impaired vision, disturbed co-ordination, unconsciousness, brain damage or even death.
The EMSD also reminded members of the public of the following:
