breathing in CO (typically from a faulty

it is too late – unless you have a CO
All powered aircraft cockpits
should be fitted with at least one CO detector.
The simplest are the chemical reaction type, like this, which
have a coloured spot which goes black in the presence
of carbon monoxide.
These need to be
periodically replaced (see the detector itself for
the relevant time period, usually six months from
opening the pack).
