Hence even trying to kill yourself in a car with the exhaust running takes quite some time and often fails. Her boiler would not have been leaking THAT much carb monox and I think even though it was faulty it would have had some form of vent not none at all. I felt the way they did do it was realistic apart from her coughing and being red faced for many days / weeks prior as that is not a symptom.
Not disregarding it is a cause of sad tragic deaths to people, this usually happens in places like cheap hotels where there is a boiler in the same room people sleep with no vent at all and heavy fire doors and sealed windows that aren't letting any draught in, they leave the heating on over night. The one thing a high level of carb monox does do is make you fall asleep, so those people would be low to the ground, and exposed for many hours overnight to an ever increasing level which is when they sadly do die.
Obviously if a person was put in small airtight chamber of carb monox, they would probably die in far less than two hours.”
Have to disagree with you there, until legislation changed a few years ago, a lot of these poisonings were caused by gas boilers in rented flats subject to low or poor maintenance, because flues became blocked, and poor ventilation to the boiler itself caused a level of carbon monoxide to build up. Deaths of people through these situations were the reason for the law to be changed, and now boilers have to be inspected by the landlord on an annual basis, with a certificate to prove it has been conducted by a qualified engineer.
CO poisoning was more frequent before we changed to North Sea (natural) gas, as when gas was produced from coal, carbon monoxide was a major component of the gas delivered into the house, hence the old references to people putting their heads into the oven to end it all.
