    HSE warns against dry cutting: control and compliance takeaways for engineers

    HSE warns against dry cutting: control and compliance takeaways for engineers

    First reported on The Construction Index

    30 Second Briefing

    HSE has banned dry cutting of engineered stone in the UK and ordered a shift towards lower-silica materials after two worker deaths from silicosis in the sector. The guidance requires wet cutting or on-tool extraction with high-efficiency local exhaust ventilation for any remaining high-silica products, bringing practice closer to controls already used on tunnelling and concrete cutting. Fabricators and contractors now face mandatory process changes, material substitution reviews, and likely revisions to COSHH risk assessments and respiratory protection programmes.

    Technical Brief

    • Dry processing of engineered stone now constitutes a prosecutable breach of the Control of Substances Hazardous to Health Regulations.
    • HSE’s guidance treats engineered stone fabrication as high-risk silica work, aligning controls with quarrying and tunnelling.
    • Employers must evidence “adequate control” of respirable crystalline silica via documented LEV design, maintenance and performance checks.
    • COSHH assessments now need explicit justification of material choice where silica content exceeds natural stone alternatives.
    • Respiratory protective equipment programmes must verify assigned protection factors are compatible with measured task-specific dust levels.
    • HSE expects written cleaning regimes using wet methods or class H vacuums, explicitly prohibiting dry sweeping of dust.
    • Health surveillance requirements tighten, with baseline and periodic lung function checks for exposed workers strongly indicated.
    • Similar control expectations are likely to extend to high-silica tile cutting, precast finishing and refractory linings.

    Trump emergency order on Colorado coal plant: reliability lens for engineers

    Trump’s Department of Energy has issued an emergency order compelling Tri-State, Platte River Power Authority, Salt River Project, PacifiCorp and Xcel’s Public Service Company of Colorado to keep Craig Station Unit 1 available for dispatch by the Southwest Power Pool, despite its planned closure at end‑2025. The directive, in force until 26 September, follows two earlier emergency orders in December 2025 and March 2026 and comes as DOE cites 17 GW of coal capacity retained in 2025. NERC’s 2025 Long-Term Reliability Assessment flags the WECC‑Rocky Mountain region’s ageing thermal fleet and supply-chain constraints as key outage risks.

    Hinkley Point C bullying concerns: ONR stance and oversight takeaways for engineers

    Regulator says additional scrutiny was not required over Hinkley Point C bullying concerns, rejecting an MP’s claim that oversight of the 3.2GW EPR nuclear project in Somerset had been intensified because of workplace culture issues. The Office for Nuclear Regulation maintains that its existing safety and quality assurance regime for Hinkley Point C, including routine inspections of civil works and nuclear island construction, was sufficient without a specific bullying-related intervention. For contractors and designers on UK nuclear sites, the dispute signals that behavioural and HR concerns will be managed largely through existing licence conditions rather than separate technical scrutiny.

    GCA £4.2bn construction services framework: key takeaways for engineers

    The Government Commercial Agency has launched a £4.2bn, four-year cross-government framework for construction professional and advisory services, open to central departments, local authorities and wider public sector clients. The framework is intended to streamline procurement of multidisciplinary design, project management, cost consultancy and technical advisory support for major infrastructure, building and regeneration programmes. Civil and geotechnical engineers can expect more standardised scopes, repeatable NEC-based call-off contracts and stronger pipelines for public sector workload across transport, flood, education and health projects.
