UK Silica Dust (Exposure) Bill Signals Proposed Tighter Controls On Occupational Health Risks

The Silica Dust (Exposure) Bill, introduced in the UK Parliament and last updated on 18 March 2026, proposes new measures to prevent, monitor and report silicosis and related lung diseases caused by workplace exposure to silica dust. The Private Members’ Bill, sponsored by Liberal Democrat MP Liz Jarvis, includes provisions targeting high-risk practices such as dry-cutting engineered stone and outlines a strengthened role for the Health and Safety Executive (HSE), with implications across construction, manufacturing and supply chains.

Proposed Controls On Silica Dust Exposure

The Silica Dust (Exposure) Bill focuses on reducing risks linked to respirable crystalline silica, generated during cutting, grinding and processing materials such as stone, concrete and ceramics. Exposure is associated with silicosis, lung cancer and other respiratory conditions. A key provision is the proposed prohibition of dry-cutting high-silica engineered stone, a practice linked to elevated dust emissions. The Bill also sets out provisions on the prevention, monitoring and reporting of silica-related diseases, alongside requirements related to workplace practices.

Screening And Reporting Measures

The legislation proposes a programme of screening for silicosis among at-risk workers. This is intended to support earlier detection of occupational lung disease, an area widely highlighted by health professionals. The Bill also includes provisions on the reporting of silicosis and related conditions. While further detail is expected as the Bill progresses, businesses should anticipate closer scrutiny of occupational exposure and health outcomes.

Implications For Industry And Supply Chains

The Silica Dust (Exposure) Bill is relevant to a wide range of stakeholders, including construction firms, engineered stone manufacturers, fabrication workshops and distributors. Companies handling high-silica materials may need to review working practices, particularly where dry processing methods are used. Importers and suppliers of engineered stone products may also be affected if demand shifts in response to restrictions on certain applications or practices. More broadly, the Bill reflects continued regulatory attention on workplace exposure to hazardous substances.

Role Of The Health And Safety Executive

The Bill makes provision for the role of the HSE in relation to occupational exposure to silica dust. This signals potential for increased regulatory oversight and guidance, depending on how the legislation develops through Parliament. Organisations may benefit from early engagement with existing HSE guidance on dust control, exposure limits and worker protection.

Next Steps For Stakeholders

As a Private Members’ Bill, the proposal is subject to parliamentary scrutiny and may evolve. However, it provides a clear indication of policy focus on silica dust risks. Businesses should consider reviewing current risk assessments, exposure controls and worker health monitoring arrangements to prepare for potential changes.
