Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government what assessment they have made of the World Health Organisation’s designation of tris(chloropropyl) phosphate as a probable carcinogen; and what steps they are taking to reduce public exposure of this compound in domestic furniture.

There is a growing concern about the health and environmental impacts of some chemical flame retardants, including tris(chloropropyl) phosphate. In June 2025, the Environment Agency published a scoping review of flame retardants relevant to the GB market. This year the Health and Safety Executive added several flame retardants to the UK REACH Candidate List of Substances of Very High Concern, signalling their potential for further regulatory control.

There is a growing body of evidence to support action to reduce the volume of chemical flame retardants used to enable upholstered furniture to pass flammability tests set out in the Furniture and Furnishings (Fire) (Safety) Regulations 1988. The Department for Business, Innovation, Science and Trade recently ran a consultation on a set of policy proposals that aim to maintain a high level of fire safety, while meaningfully reducing the reliance on chemical flame retardants.
