Stormin Norman,
With respect, RoSPA (Royal Society for the Prevention of Accidents) has just published a 5 page article on contaminated air - this month!
You can see it on the Aerotoxic Association web site -
here.
RoSPA will be doing an even harder hitting article next month on just how the airlines, CAA and HSE flout the rules that every other industry obediently follows.
Balpa reportedly told the Rospa journalist that the chemicals in aircraft fume events were '....no worse than experienced when walking along a high street'.
Not what Balpa concluded at their conference in 2005, where they stated that exposure to fumes causes chronic ill health....
If you fly bleed air aircraft, you really ought to know what you are breathing. Especially when the bleed air system goes wrong.....
