The gas is odorless, so victims are unaware of the potential danger. Closed air conditioning circulation accelerates the diffusion process of toxic gases.
At certain levels, CO gas is still safe for humans. However, as CO levels increase and oxygen levels in the blood decrease, the body becomes intoxicated and debilitated until it eventually loses consciousness. In many cases, victims do not even know that they have been poisoned by the toxic gas.
The risk of CO gas poisoning is much lower when the vehicle is in motion, as the person is conscious and quickly senses abnormalities.
Also, gusts of wind can push toxic fumes backwards from under the car and not into the passenger compartment.
4. Find a safe parking spot
What if I’m driving alone and I’m still sleeping because I’ve exceeded my driving time for the day?
Avoid sleeping in enclosed areas such as basements. Air circulation is poor in this area, making it difficult for poisonous gases to escape.
Find a place where you feel really safe. For rest stops and gas stations, look for locations near busy areas such as guard posts and mini markets.
If you are sleeping at night and the air is not hot, turn off the car engine and air conditioner and open the windows.
