A family of three in Hong Kong suffered carbon monoxide poisoning from a gas water heater at the weekend, prompting an investigation by authorities.
The Post examines how to prevent carbon monoxide poisoning and what precautions should be taken.
1. How did carbon monoxide poison the family?
The Centre for Health Protection revealed on Sunday that a 56-year-old man, the father, was found unconscious after taking a shower on Saturday.
He was sent to Yan Chai Hospital in Tsuen Wan before being transferred to Pamela Youde Nethersole Eastern Hospital in Chai Wan.
Two family members, his wife and their 13-year-old boy, were also exposed to excessive carbon monoxide and taken to the same hospital from their home at Tai Wo Hau Estate.
All three are stable, with two already discharged. They were diagnosed with carbon monoxide poisoning. Investigations revealed that when the father took the shower, all the windows in the flat were closed, and the exhaust fan was not turned on.
An Electrical and Mechanical Services Department investigation found the gas water heater was flueless, a type banned for use in bathrooms. The model was also not approved by the department and did not bear a “GU” mark.
