DRY ICE

Remember this esp. when we buy lots of ice cream during Baskin
Robbins 31st day offer!!! They normally put dry ice in your ice cream
pack if you buy a lot.

A friend bought four pack of ice cream and to prevent it from
melting, the seller put the dry ice amongst the ice cream. My friend put
it at the back seat (not the back of the car) and he started to drive
with the windows closed and the aircon on (as what we all do).

Soon after that, he had difficulty to breath and it was getting worser by
minutes. Luckily, he was in a traffic jam and when he almost fainted,
beside him was an ambulance. He dragged himself to the ambulance and got
the oxygen treatment. He was getting better on the way to the hospital.

The ambulance officer drove his car to the hospital and he had
the same experience. However, before his condition worsen, he opened up
the window and he can breathe easily. Only later, when my friend
has returned to office and told his colleagues about his story,
they pointed to him that the dry ice was the problem. WHY?

Dry ice was made of CO2 and when it "melts", it becomes CO2 gas
straight away without leaving any wet mark (that is why it is called dry
ice).
CO2 is easier to be tied up in our blood and thus, when the dry
ice sublimes into CO2 gas, it fills the car room with it along with
the aircon circulation and caused CO2 poisoning. So, dont put the dry
ice inside your car if you are using aircon with fully closed
windows. You must leave the windows open for such situation.

Hope this will help to prevent any fatality just from a small
negligence like this. Imagine if you have your children inside,
they might be the first victim..
