We started this thread and are pleased at the mostly constructive replies and open debate that has followed.
We would like to make a couple of observations.
Point 1.
Danny stated: We are not talking about carbon monoxide associated with combusted fuel.
This may be correct but
we are talking about carbon monoxide associated with the pyrolisis of engine oil especially on the BAe 146. I am aware as is BALPA of many UK crews flying the 146 with elevated Carbon Monoxide readings on many flights with good quality CO detectors.
Point 2.
Martin Alder of BALPA states: no one contacts BALPA FSG we do not know of a problem whatever it is and cannot do anything about it either, we are not mind readers!
We at AOPIS are aware of at least 14 BALPA members who now suffer long term the effects of contaminated air exposures as well as several hundred who have suffered short term in the UK. I have evidence that many of the long term sick members did contact BALPA so it is unfair to imply no one has contacted the FSG.
An AOPIS member gave a talk to the BALPA Medical Study Group some years ago and highlighted this very fact.
Perhaps someone from BALPA could confirm the exact number of crews who have suffered short term and long term symptoms to get a scale of the issues within BALPA.
