The Countess of Mar
To ask Her Majesty’s Government how air crew and passengers in commercial airlines without filtration or detection systems are warned, protected and informed in the event of a fume incident from contaminated bleed air.
The Countess of Mar (CB)
My Lords, I beg leave to ask the Question standing in my name on the Order Paper. In doing so, I declare my interest as patron of the GCAQE.
The Minister of State, Department for Transport (Baroness Kramer) (LD)
My Lords, operators are required to include detailed instructions to crew on procedures to be followed when contamination of cabin air is present or suspected. Any passenger who became unwell would be given first aid by the crew and, if necessary, referred for further medical assessment and care after landing. There is no national or international legislation requiring air crew or passengers to be informed of fume events.
The Countess of Mar
My Lords, it is almost 60 years since the danger of fumes seeping into cabin air was first reported. With the notable exception of the Boeing 787, virtually all passenger jets still have flawed and potentially dangerous bleed air systems, a design that leaks pyrolised oil into the air supply. Does the Minister agree that most shocking of all is the fact that airlines fail to inform passengers that they have been exposed, which—and I have chosen my words very carefully—must be a breach of passengers’ rights and casts a dark reflection on the aviation industry? What solutions does the Minister have?
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 Wigley (PC)
But does the Minister not accept that there is genuine concern about the lack of information about concentrations of pollutants during major fume events? These have not been adequately collated or analysed and, given the Government’s responsibility in these matters, can she instigate some research that could try to get to the bottom of this?
Baroness Kramer
My Lords, the studies which were carried out over a period of nearly six years—the investigations by the department, including the four independent research studies that I described a few moments ago—and the work of the committee on toxicity have led the department to conclude that there is no further direction to pursue in terms of research on this issue for UK aviation. If there is to be further research, it will be at international levels. As I say, there is no indication of a sufficient concern or basis for research being recognised by those international organisations.
Lord Elton (Con)
Could my noble friend complete her answer to my noble friend Lord Tyler by telling us whether there is a requirement on airlines to report incidences when there has been a fume event exceeding the parameters which she has already described?
Baroness Kramer
Incidents on aircraft flights, including any fume event which in the opinion of the airline, any member thereof or any passenger,
“endangers or which, if not corrected, would endanger an aircraft, its occupants or any other person”,
are required to be reported under the mandatory occurrence reporting scheme, known as MORS, which is run by the UK’s independent aviation regulator, the CAA. An investigation carried out by the operator would then typically follow. If the CAA was not satisfied with that investigation, it could ask for further work to be undertaken. It is a CAA responsibility to monitor for trends and unrecognised safety threats.
Lord Davies of Oldham (Lab)
My Lords, I have some sympathy with the Minister as I have on occasions from that Dispatch Box also produced responses that did not satisfy the noble Countess, Lady Mar, nor many other Members of the House. I therefore ask the Minister this question. If she is able to give the degree of reassurance that she has given about the monitoring that we carry out, but if the issue is a great deal wider than that—she made no reference at all to how other countries attack this or to the European position in general—will the Government at least push the authorities into examining this matter further? The consequences of getting it wrong would be quite disastrous.
Baroness Kramer
My Lords, the noble Lord will be very well aware that the CAA, which is responsible for monitoring and safety, keeps not just this issue but many others under review. I feel confident that if the CAA had sufficient concern that it felt that there needed to be urgent research, it would inform the department of that and would be pushing on those issues. As I said, there has been very substantial research in this country and in other countries which has led to firm conclusions. Given that, it is hard to see what direction additional research could possibly go in.
