Cabin Air Safety/Aerotoxic Syndrome

Chris Stephens Excerpts

Thursday 17th March 2016 Westminster Hall

[Liz McInnes]

I thank the Minister for that intervention; that is very useful information. It reinforces the point about speculation and causative effects. Obviously, cabin crew say that the air issue was the reason why the 787 was developed with that system. If there is a public inquiry on this matter, I hope that information about that system will form part of the evidence.

My hon. Friend the Member for Stalybridge and Hyde said that some statistics showed that fume events occurred in one flight in 2,000. One of the statistics that I pulled out is from the Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment. COT reported in 2007 that fume events occur on one flight in 100, so again there is some dispute over the incidence of these events. There is also anecdotal evidence that fume events occur even more often than that, but they are not being reported. The really surprising thing about all of this is that there are no chemical sensors in the aircraft. The noses of the cabin crew are the only detectors.

My constituent asked me not to give her name, but she was quite happy to talk to me about her experience as a cabin crew member. She described these fume events to me. She said that she has been in cabins when fumes have entered. She has flown for four different airlines and fume events have happened in planes from all four of them. She said to me, “Fumes come in. You smell the oil. It’s not being acknowledged by managers and higher officials in the airline industry when these incidents are reported.” When I spoke to her, she compared the effect of fume events with Gulf war syndrome. With Gulf war syndrome, we had soldiers coming back to the UK with massive neurological problems and it took a very long time for any investigation to be made and for it to occur to somebody that these problems were happening too often to be a coincidence. It is interesting that she made that comparison.

My constituent said to me that all cabin crew want is for this problem to be recognised and acknowledged. Until we have a full investigation, cabin crew will not feel that their employers are doing everything they can to safeguard them while they are at work.

[Chris Stephens (Glasgow South West) (SNP)]

Is part of the issue the lack of training for cabin crew to deal with these incidents when they occur?

[Liz McInnes]

I thank the hon. Gentleman for that intervention. From the research I have done and from the comments of people I have spoken to, I know that that is probably true. My constituent told me, “Smoke hoods are there in the plane if there is a fire or fumes on board.” Until recently, those smoke hoods had been used very rarely, but she told me that crew members were starting to use them because of their concerns about fume events on flights. Again, that is anecdotal evidence, but it shows the real concern out there and highlights an issue with training. These things should not be used, but they are used because crew are fearful for their health. He makes a good point, and I am grateful to him for raising that issue.

My hon. Friend the Member for Stalybridge and Hyde and various other Members have spoken about when the incidents started to be reported. My constituent said that she first heard of it 1998, when she started working for an airline. She said that cabin crew were talking about fume incidents even then.

Several hon. Members have mentioned the cases in which deaths unfortunately occurred, possibly as a result of aerotoxic syndrome. I, too, first became aware of the issue at a Unite briefing, where the parents of Matt Bass described what happened to their son. His symptoms appeared to be fairly non-specific, but it was reported that he was fatigued. He went down to rest and tragically he never woke up. There is a feeling that his symptoms were consistent with exposure to organophosphates, which are the chemicals that leak out occasionally in the bleed air.

I am grateful for that intervention; I did not mean to misrepresent the hon. Gentleman’s position. It is important that we look at evidence. Considerable pressure is building to have a proper investigation and to make an objective assessment as to whether there is a causative link between the symptoms, which are wide and various—I do not propose to go into them again because other Members have already done that—and exposure to toxic air fumes that have come from engines through bleed air systems.

Other Members have referred to the new generation Boeing 787 Dreamliner, which uses bleed-free systems. Those systems are not an industry standard, nor does Boeing’s decision seem to mark the beginning of a transition to a safer system. I echo the comments of my hon. Friend the Member for Stalybridge and Hyde, because, apart from anything else, Unite has a substantial number of members involved in the aviation industry—not just flight and aircraft maintenance crew but those working in the manufacture of aircraft components and engines. I do not seek to damage confidence in the industry, but it is important that we ensure that this safety-critical industry enjoys complete confidence and we have those necessary assurances and investigations.

rose—

[Grahame M. Morris]

I will give way to my friend, the hon. Member for Glasgow South West (Chris Stephens).

[Chris Stephens]

Is there not also confusion about which body is responsible for occupational health and safety? It seems to be split between the Civil Aviation Authority and the Health and Safety Executive, and that is confusing in terms of the Control of Substances Hazardous to Health Regulations 2002—the hon. Gentleman will be familiar with them—which the CAA has denied responsibility for.

[Grahame M. Morris]

That is a good point. I hope that the Minister will reflect on it and perhaps refer to it in his response.

I am afraid that we do not have a lot of information on the frequency of these events in the United Kingdom. The much-criticised UK Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment estimated that smoke and fume events are reported by pilots in one in every 100 flights—I think that was previously mentioned—but those are conservative estimates. If there is under-reporting, as many seem to believe anecdotally, that might be another reason why many fume events are not being investigated. As my hon. Friend the Member for Brent Central (Dawn Butler) mentioned, it is important to monitor in real time rather than bring portable equipment on to aircraft when they have landed.

I understand that UK fleet figures are not available—if the Minister does have such figures, I am happy to take an intervention from him to put them on the record—but what was initially thought to be quite a rare event anecdotally seems to be happening far too often. Figures available from the United States are quite alarming, although they have many more aircraft and flights. Clearly exposure to contaminated bleed air can have a serious impact on health, particularly for cabin crew, who are at greater risk of exposure and of cumulative effects.

We have already heard about the coroner’s letter following the sad death of pilot Richard Westgate and the regulation 28 report, so I do not intend to go into that. However, it seems to be an omission that there is nothing on the public record. We have heard quotes from the Civil Aviation Authority response to that letter, but we have not seen the full response. The CAA said that

“there is no positive evidence of a link between exposure to contaminants in cabin air and possible acute and long-term health effects”.

Although it did conclude that

“such a link cannot be excluded.”

I am not sure what good that is. It seems to me that this issue is crying out for some further research and evidence so that we can either establish a link or rule it out.

I am prepared to concede that there is a knowledge gap, but the industry and regulators are relying on a system of denial rather than fitting the detection systems required to collect evidence on the true number and concentration of fume events. I do not believe that the industry—or the Government for that matter—would deny the existence of fume events. Again, the Minister can correct me if I am wrong, but I believe they also accept that fume events are detrimental to health. While they may disagree on the extent of such impacts, I ask the Minister to support calls for an independent inquiry into the risks and hazards associated with contaminated air.

We need monitoring and detection systems for cabin air to be introduced so that we can ascertain the true extent of the problem. We also need a better system to diagnose, treat and compensate workers whose health and wellbeing has been compromised and damaged by fume events. Finally, all future aircraft should be designed to be bleed-free. If there is a shred of doubt about there being cumulative, long-term adverse effects on health, surely that is a sensible way to proceed when drawing up design specifications. In the meantime, it is possible to mitigate any effects, perhaps by looking at maintenance schedules, because aircraft that are not maintained to such a high standard are more likely to be subject to fume events as seals go—that is the nature of a mechanical design. Things could therefore be done; indeed, engine oils and hydraulic fluids could be reformulated to minimise potential adverse effects on health.

Ultimately, we need airlines to step up to the plate and accept their responsibilities and duty of care to employees and passengers. If not them, regulators need to demand changes, and detection systems should be fitted to seek further evidence on fume events. If not the airlines or the regulators, the Minister and the Government must take charge. Until such time, I do not believe any of us—the travelling public or indeed air crew—can say with confidence that air travel is completely risk-free and that fume events are not a risk to public health.

[Mr Goodwill]

I could not agree with the hon. Lady more. I am laying out what research has been done and what information we have to date. That is why it is very important that EASA makes further progress. Indeed, we are keen to find out what research is happening around the world. Because of the international nature of the aviation industry, it is the Government’s view that an international approach to any future research investigations would be appropriate.

[Chris Stephens]

Will the Minister comment on the occupational health and safety aspect and look at this issue again? It seems to me that air cabin crews’ Health and Safety Executive protections apply only when they are on the ground and outside the aircraft. Things such as Control of Substances Hazardous to Health Regulations seem to be falling through the net between the CAA and the HSE.

[Mr Goodwill]

My advice is that the CAA is the body responsible for the safety of crew and passengers in this case, and the CAA, as I have said, takes this very seriously. We are working with international bodies such as EASA to try to progress some of the research. The opportunity to collect data from a broader sample base than is available in the UK—

[Chris Stephens]

The Minister has been most generous in accepting interventions. My understanding is that COSHH regulations would apply to much of this, but that the CAA has said that COSHH regulations do not apply to it. Could the hon. Gentleman go away and look at that, in terms of the health and safety protections that should apply to these workers?

[Mr Goodwill]

I am certainly happy to interrogate the CAA on its interpretation of the rules on COSHH. I am well aware of the operation of the regulations; as a former road tanker driver, I know all about COSHH regulations. But of course aviation is an international business and aircraft are not necessarily within our jurisdiction as they are flying, so it is important that we have international agreements. Indeed, many aircraft that carry British nationals are flagged to other countries around the world, and therefore we need to ensure that their standards are as high as ours and that work can be progressed internationally.
