Aviation: Fume Events

Lord Tyler Excerpts

Tuesday 18th March 2014 Lords Chamber

[Baroness Kramer]

My Lords, on most commercial aircraft the cabin air supply is provided by engine bleed air, which is drawn from the compressor stage of the engine. Contamination, known as a fume event, may occur when oil or hydraulic fluid is released into the bleed air—for example, as a result of an oil seal failure—resulting in the formation of a fleeting odour or mist in the aircraft cabin. Most fume events last less than a minute or two.

Many investigations have been carried out by the department, of which the noble Countess will be well aware. The committee on toxicity concluded that there was no evidence for pollutants occurring in cabin at levels exceeding available health and safety standards and guidelines and, as most levels observed were comparable to those typically experienced in domestic settings, there is appropriately no requirement for passengers to be informed. There are many steps to be taken if there is an assessment that there is any endangerment to any passengers or to the flight.

[Lord Tyler (LD)]

My Lords, is my noble friend aware of the work undertaken by the all-party parliamentary organophosphate group, of which the noble Countess and I were both members? Can she in particular tell us whether there is continuous monitoring of incidents and potential risks, following the Cranfield study some years ago? It is my impression that there is no continuing monitoring—I do not think that there has been any recent report on this—of incidence in a global sense, even if there is one for UK operators.

[Baroness Kramer]

My Lords, as your Lordships will be aware, for six years the department carried out significant research into these issues, and quite appropriately so. That research led to four studies, the main one of which was the Cranfield study published in May 2011. All four reports were sent to the committee on toxicity, which also peer-reviewed other international data and came to the conclusion that I just discussed: that cabin air at levels exceeding available health and safety standards and guidelines was not evident in any of those studies. Going forward, I think it therefore becomes an international issue and it is a matter for the European Aviation Safety Agency or the International Civil Aviation Organisation to consider whether more research should be done. At this point, I am not aware of any concerns that they have for ongoing monitoring or further research.

Lord Tyler Excerpts

Wednesday 8th December 2010 Lords Chamber

[Earl Attlee]

My Lords, I would be surprised if that had not been covered by the studies of our critical national infrastructure, but I shall write to the noble Lord on the detail.

[Lord Tyler]

My Lords, the Minister quite rightly referred to the need for the best possible technology. I was witness to the work of the coastguard helicopters and others at Boscastle and Crackington Haven during the devastating floods of six years ago. Can he assure me that the problems encountered then of liaison between the helicopters in difficult terrain along our coastline have been dealt with in terms of improved technology?

[Earl Attlee]

My Lords, I cannot give specific assurances, but the proposal is to make sure that the radio systems are up to date, particularly in the use of digital networks.
