In the malay newspaper today, it stated that the guy was sitting on top of her, can't really figure out wat position they were in this case...Usually its the other way round i think...not too sure lah me very blur in all this must read book...
sometimes speculation serves more confusing for others.so thats why the nobody can ans the qns,only themselves.. everybody noes wat's with them, u noe, i noe .
From the paper... (Ride Bike Suah!!!)
YOU won't be able to smell, see or taste it, but this gas is deadlyprecisely because of that.
Miss Linda Gian, 19, and Mr Jerome Peck, 33, were found dead in an old Suzuki Swift on Saturday night.
The police have confirmed that the cause of death for both is cardiorespiratory failure. Blood tests are being conducted to determine if this was caused by carbon monoxide poisoning.
Q: How does carbon monoxide kill?
A: It replaces oxygen in the body causing the organs to 'suffocate', said Professor Andy Hor, head of the Department of Chemistry at the National University of Singapore.
'Carbon monoxide and oxygen are similar in that they don't have a smell or taste, so when you breathe in carbon monoxide, you won't sense anything is wrong for a while, though your body will be coping with less and less oxygen.'
In high concentrations, carbon monoxide can kill a person in minutes, while in lower concentrations, the person will faint in a few hours, and then die if not rescued.
Q: How does it get into a car?
A: In some cases, especially with older cars, it can enter through the door, window, parking brake, boot and ventilation seals, said Mr Gregory Lim, section head of Automative Technology at ITE Balestier.
He said that as a car ages, these seals start to degenerate because of wear and tear. Also, the floor boards of the car may start to corrode. Exhaust fumes can then enter the car through these gaps.
If carbon monoxide, a by-product of fuel combustion, enters a car and accumulates undetected, it can cause death.
Q: Why are newer cars safer?
A: The seals are new, said Mr Lim.
Also carbon monoxide emissions are low because of the presence of catalytic converters and more fuel-efficient technology. Older cars can produce up to 50 times more exhaust gases than newer ones.
Q: Under what conditions do carbon monoxide accumulate in lethal amounts in a passenger compartment? Are stationary cars more susceptible?
A: Mr Lim said carbon monoxide poisoning is very unlikely to occur in a moving car, because the exhaust fumes are emitted at the back of the car, as the vehicle moves forward.
It can still be dangerous if the exhaust fumes are leaking from the engine itself, which can happen in very old cars, or when the exhaust system and floor board are corroded.
If the car engine is not running, no carbon monoxide is produced even if the battery is being used to run the headlights or sound system.
Stationary cars in enclosed spaces with the engine left running are most at risk of carbon monoxide leakage. Car manuals usually warn against it.
In air-conditioned cars, drivers can switch between 'recycle air' and 'fresh air' modes. In Singapore, it is common for drivers to set it to recycle mode, which effectively seals the cabin - unless there's a gap somewhere.
In fresh air mode, carbon monoxide can find its way into the ventilation system if the car engine is running in an enclosed area like a garage.
A carpark, even sheltered, is fine unless the car is parked with its exhaust pipe too close to the wall and air circulation in that area is poor.
Q: So how to guard against it?
A: Mr Lim advised owners to send their cars for regular maintenance as instructed. If the car is more than 10 years old, it should be serviced every 5,000km travelled.
That's the only way to check that the car is not emitting too much carbon monoxide, and that there is no corrosion of the undercarriage.
