An increasingly popular LPG-based water heater, better known as the Chinese Geyser, is being linked to more than a dozen carbon monoxide poisoning deaths that have occurred in bathrooms in Bangalore over the past two years. Forensic analysis of blood and viscera in eight bathroom deaths have confirmed carbon monoxide poisoning as the cause. Five women and two children were among those found dead in cases initially dismissed by the police as accidental drowning or heart -attack deaths.
