BRITAIN’S PILOTS CALL FOR MAJOR INVESTIGATION INTO
AIRCRAFT CONTAMINATED AIR
Britain’s pilots are calling
for a major investigation into the causes and effects of contaminated air in
aircraft passenger cabins and cockpits and are co-ordinating the first
international conference on this issue.
The British Airline Pilots’
Association (BALPA), which represents more than 8,000 of the nation’s 10,000
airline pilots, has already stressed to pilots the need to record in the
aircraft technical log and air safety reports whenever cabin air becomes
contaminated for any reason.
Currently, almost all commercial aircraft draw the air for
the cockpit and passenger areas from the engines. This is known as ‘bleed air.’
The contamination of particular interest is engine oil
‘There has been concern in
the civil aviation industry for a long time about the contamination of cabin
air,’ said BALPA chairman Captain Mervyn Granshaw.
‘Now we are determined to
get to the bottom of it.’
BALPA has joined forces with University College, London,
Imperial College, London, and others and submitted a detailed research proposal
to the UK Aviation Health Working Group, which is part of the Department of
Transport.
Also backing the proposal
are cabin crew, represented by the Transport and General Workers’ Union and
Amicus, and the Occupational Health Research Consortium in Aviation in North
America.
To date there has been no
successful measurement of cabin air quality during a ‘contaminated air event’.
Of particular concern is the fact that there is no published research into the
effects of repeated low-level exposure to the products of pyrolysis
of fluids likely to be present in hot bleed air and its subsequent effects via
inhalation on pilots, cabin crew and passengers.
Doctors treating crews and passengers following exposure
to contaminated air currently have little, if any, guidance on treatment.

Although contaminated air
events are generally infrequent, the contaminated bleed air issue has been
ongoing for over 20 years. For this reason it will now take centre stage at an international Contaminated Air Protection Conference being
co-ordinated by BALPA and held at Imperial College, London, on April 20 and 21.
In 2004, the organophosphate
TCP, PAN and other potentially toxic compounds were discovered in the cockpit air of military aircraft using
the same engine oil as used in commercial aviation (Exxon Mobil Jet Oil ll). It was later found in the air conditioning ductings of some commercial aircraft in the UK. This
alerted the industry to the potential for low level exposure to such compounds
to be harmful.
‘This gives urgency to our
call for an investigation,’ said Captain Martin Alder, BALPA’s Flight Safety
Group chairman. ‘Evolving medical and scientific thinking supports our call for
a research programme to thoroughly investigate this area of concern. Our
detailed proposal offers the most cost effective way of sampling ‘contaminated air events’ as they
happen, suggests a medical protocol for dealing with affected crew members, and
will give us a clear idea of the scale of the problem we may be facing.’
