Friends,
Very sad, there was another story on CO poisoning, now with Zen. I was very curious to know whether this is happening in India (bad QC/older technology dumping ground!) or anywhere else?
Any insights/experience suggestions would be helpful for all of us, as we do this very frequently...leaving our family members inside the car with aircon running for elongated period of time. Recently I did so, as my kid was sleeping and I was forced to let her sleep with my maid inside the car for almost an hour or so with air con running. After reading this, I feel how stupid I was then. This post in someway to induce some thoughts and as well as to serve warning for others.

Carbon monoxide poisoning caused death of youth: police
· CO can induce a feeling of intoxication on entering the blood
· Signs of CO and cyanide poisoning are almost similar
Thiruvananthapuram: The police on Monday said that "chance inhalation" of fatal amounts of carbon monoxide (CO) had caused the death of the three partying youngsters, including a girl, whose putrefied bodies were found next to a car parked inside the shuttered garage of a house in the city last December.
The incident is in some ways similar to the death of three software engineers who inadvertently inhaled lethal amounts of the odourless gas emitted by their vehicle when the car was caught in a traffic jam caused by heavy rain in Chennai in October 2006.
The youth had pulled into the garage, owned by one of them, in a Maruti Zen car for a "quick and discreet" party around 3 p.m. on December 7. Ten minutes earlier they had bought a bottle of liquor from a nearby outlet. One of them had made a final call on his mobile phone at 4.45 p.m.
The girl was found dead in the car while the bodies of the youth were seen sprawled on the garage floor. The police suspect that the youth had exited the car at the last minute and made a vain scramble for the garage door. The garage was closed from inside and its construction left little scope for any other type of ventilation. The youth were partying inside the car with its windows rolled up and air-conditioning switched on, forensic experts said.
Petrol engines emit considerable amounts of CO, often up to 25 per cent of the exhaust gas. Most modern day vehicles, such as the Maruti Zen, are equipped with catalytic converters that minimise CO emission (CO is often a product of in-effective combustion).
The car was idling for more than an hour in the enclosed space and the engine got deprived of sufficient levels of oxygen needed for proper combustion. Inefficient combustion and lack of proper ventilation caused lethal levels of CO to accumulate in the garage. The air-conditioning system sucked much of the deadly gas back into car's closed cabin space, causing the deaths of the occupants, the experts said.
Forensic doctor and the former Director of Medical Education Umaduttan said that deaths due to CO poisoning were rare in Kerala.
He said more people died from oxygen deprivation while cleaning wells and septic tanks in the State. One incident of CO poisoning, which later turned to be a case of suicide, was reported in the city in the late 1980s. The victim had inhaled the gas by attaching a tube to the exhaust pipe of his car.
He said the "colourless, odourless gas" had an affinity for haemoglobin and bonded better with blood than oxygen. When it enters the blood stream, CO can induce a feeling of intoxication. The youth could have confused the giddy sensation as one caused by consuming alcohol. Signs of CO and cyanide poisoning are almost similar. Tissues and blood of the victim turn a "strange pinkish" colour, he said.
