For the cynics that don't believe this is an issue because it never afffected them read on.........
18 months ago I suffered a serious fumes event on a 757; on landing the cockpit filled up with fumes & both of us were affected to a degree.....I stopped the a/c & shutdown on the first available parking slot, from that point on I was effectively incapacitated. I was concious but couldn't focus, my skin was burning, my eyes watering & my throat swelling. I was taken to a German Hospital where they carried out a number of blood tests & refused to release me as 4 blood tests taken showed my blood levels were outside of accepted levels for toxins. The same company has had in excess of 40 incidents this year alone...........they even took scientists on board to monitor a flight & the scientists witnessed a fumes event whilst on board

The report for that has yet to be released
Eventually I was released & returned to the UK whereby I attended Biolab in London (the only Lab I am aware of that can test for TCP'S)...they informed me they were getting at least one call a day from flight crew regarding fumes. I had a number of blood tests & a biopsy taken, the results were shocking. My body fat cells were showing levels of TCP's 70 times more than allowed in industry, I have never worked around farms/ weedkillers etc so there is only one place the TCP's could have entered my body. I took the decision to move on to another a/c & since then my general health has improved markedly. I have greater mental ability, my memory has got better & I find I don't suffer with headaches following flights.
Just because you have a higher tolerance or haven't suffered the effects of these toxins don't knock the people who are suffering.........I have seen an internal RR memo that states it is a known problem........Do you really think the CAA & COT will find anything, imagine the law suits if it were proven, a number of airlines would cease to exist overnight.
And I'm not a conspiracy theorist, just someone worried about what the future holds for their health!
