Woman found unconscious in shower due to carbon monoxide poisoning

A 36-year-old woman was rushed to hospital on Thursday after she fell unconscious due to carbon monoxide poisoning while taking a shower. She is now in a stable condition. 

The woman was first found unconscious in the shower at home on Thursday and was sent to Caritas Medical Centre. She was later transferred to Pamela Youde Nethersole Eastern Hospital for treatment. 

The Electrical and Mechanical Services Department conducted a site investigation immediately and confirmed that there was no town gas leakage at the scene. 

“The subject gas water heater was installed in 1995. It is a model before the scheme for Approval of Domestic Gas Appliances took effect in 2003 and therefore did not bear a ‘GU’ mark,” the department said. 

Investigation also revealed serious corrosion at the bottom of the gas water heater, causing the incident. The department therefore seized the subject gas water heater for further investigation. 

The Centre for Health Protection reminded the public that a gas water heater should be used in a well-ventilated area. 

“Carbon monoxide is a colorless, odorless and tasteless gas which is a by-product from incomplete combustion of any fuel which contains carbon, such as wood, natural gas and gasoline,” the CHP said. 

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 coordination, unconsciousness, brain damage or even death. 

Citizens should seek medical attention immediately if suspected of developing symptoms of carbon monoxide poisoning.
