I simply cant understand what part of the colourless odourless gas part of the Description of CO people on this forum have not got into their brains.
Each year I see in the press tragic events from CO poisoning from gas stoves, central heating boilers and other combustion sources , there are a great number of regulations in the industrial and domestic environments, this reflects the danger that the authorities see CO poses to the users of such equipment simply because of the subtle way CO incapacitates it’s victims.
Both the aircraft manufacturers and aviation authorities recognise the danger of CO and put in place regulation mitigate the risks .
Yet with all this evidence some above think they will smell the CO and be able to something about is, perhaps the only comfort we can take from this attitude is these people will simply not know what killed them.
