Question to the Department for Transport:

To ask the Secretary of State for Transport, whether her Department plans to require the installation of real-time cabin air quality monitoring sensors on commercial aircraft operating in the UK.

The UK has a well-established regulatory requirement for reporting events that could endanger aircraft outlined in UK Reg (EU) No 376/2014. Fume and smoke events must be reported and are subsequently analysed by specialists working in the Civil Aviation Authority (CAA) to inform policy.

The scientific literature on toxicology of fume events is under continuous review by colleagues working in the CAA’s Medical Department. The CAA position statement on Cabin Air Quality can be found at this webpage. This includes a detailed overview of the research that has been undertaken on the topic and the conclusions of a recent study commissioned by my department and undertaken by the Committee on Toxicity (COT). This found that levels of the chemical contaminants reviewed in aircraft cabin air are unlikely to cause adverse health effects following acute or long-term exposures.
