Civil Aviation (Consumer Protection and Regulatory Reform) Bill [HL]

Baroness Finlay of Llandaff Excerpts

Report stage
Monday 13th July 2026 Lords Chamber

[Lord Empey (UUP)]

My Lords, we discussed this in Committee. It affects all of us who use aircraft on a regular basis—and, more importantly, those who fly and crew them, who live in a capsule with artificially filtered and pressurised air. Over the years, we have had examples of oil seals in engines leaking and vapour coming into the cabin, which has largely been down to either design faults or poor maintenance.

I have a close relative who works in the industry and spends his time in a cockpit. We know that, in that compressed environment, the air you breathe in can sometimes be contaminated with mineral oils, since the air is bled from the engines and pressurised, and in some cases heated, before being brought into the cabin. It is true that pilots quite frequently have a separate air supply from that of the passengers, but ultimately it all comes from the same fundamental source. The issue is contamination from these oils; they are there to help the engine, but this has the effect of breaking them down into their components, some of which can be toxic.

I am simply asking for the Secretary of State to

“conduct a review to establish responsibility for standards of air quality on civil aviation planes”.

We are now seeing longer journeys than ever, with people flying in an aircraft for 14, 15 or 16 hours. This issue is extremely important for those who earn a living in these environments and spend vast parts of their lives there. This is not a new phenomenon in industry; we have had it in mines, factories and all sorts of environments. In addition to being a location where passengers are carried, an aircraft is a location where people work. It therefore seems not unreasonable for us to pay significant and serious attention to this and ensure that we guarantee, as far as possible, the health and safety of the people who work in the industry and the rest of us who use it.

This amendment is not an unreasonable thing to ask for; it would not impose any huge burden on the Secretary of State, other than to review. We also need clear lines of responsibility. I hope the Minister can address this, because this amendment is not just about requiring a review of the health implications of long-term exposure to pressurised air. If we want to encourage people to join and use the sector, then they must be satisfied by the health and safety standards.

In proposed new subsection (2)(b), I have asked for the review to

“provide guidance for implementing a strategy for the establishment of standards of air quality on civil aviation planes”.

I think the Minister will find that that is not a burden on his department; it is a perfectly sensible and reasonable thing to do. Aircraft are places where we all spend a lot of time—some of us spend more time in them than others. If you work in one for your career, whether as a pilot or a member of the cabin crew, you are spending most of your working life in that environment, so it is not unreasonable for this to be reviewed and examined by the Secretary of State and that any necessary steps are taken. I beg to move.

[Baroness Finlay of Llandaff (CB)]

My Lords, I remind the House that I am president of the CO Research Trust. Cabin air quality is a critical issue. I am grateful to my noble friend Lord Empey for the way he introduced this group, and for co-signing my amendment.

My Amendment 37 would create a statutory duty on air operators to install continuous active monitoring for carbon monoxide and volatile organic compounds in the cockpit and passenger cabins, and provide an immediate alert to the crew and direct data reporting to the Civil Aviation Authority. I thank the Minister for meeting me last week and for the very constructive and open discussion we had. I hope he can confirm that the Civil Aviation Authority has the powers to act on cabin air quality and is willing to meet to see how we can best ensure this aspect of passenger and crew safety, as we would then not need to seek to put these powers in this primary legislation.

It has been interesting to go back over some air disaster reports, as the possibility of carbon monoxide and volatile compounds seems not to have been fully considered in some instances, along with questions over the possibility of fumes in the cockpit, even when pilot hyperventilation was noted. As we become increasingly aware of the dangers of low-level carbon monoxide exposure, particularly over prolonged periods, cabin air quality is critically important. I remind the House that HEPA filters deal with viral and similar particles in recycled cabin air but do not capture gases. In any case, carbon monoxide and volatile organic compounds enter the cabin’s air intake directly from the engine turbines—in other words, before the filters deal with recycled air.

In Grand Committee, the Minister referred to the committee on toxicity reporting that normal levels of chemicals found in cabin air are not likely to be harmful. But a fume event is not a normal occurrence, and we have to take a precautionary approach. It is a mechanical failure, for which carbon monoxide is an easily detected indicator of contaminated cabin air. Operators must report and investigate any suspected leaks, but the paradox is that an operator cannot report a suspected leak of carbon monoxide without any monitoring, as the gas is colourless and odourless, which explains why carbon monoxide exposures are undetected and unreported without monitoring.
