The Health and Safety Executive is stepping up visits to construction projects across the UK with a sharper focus on how sites control respirable crystalline silica (RCS) when cutting, drilling and breaking mineral materials. Contractors, demolition crews, fit-out teams and specialist trades working with concrete, brick, block, stone and tiles are all in scope, according to industry briefings and site reports of increased attention. Inspectors are expected to look closely at planning, supervision and the practical controls used at the workface, rather than relying on paperwork alone. The direction of travel is clear: stronger evidence that dust risks are being eliminated or reduced to as low as reasonably practicable. That means greater scrutiny of water suppression, on-tool extraction, local exhaust ventilation and respiratory protective equipment, alongside training and health surveillance. For a sector managing tight programmes and multiple subcontractors, the operational detail of dust control is moving centre stage.
TL;DR
/>
– Expect unannounced HSE visits that test dust control at the workface, not just the RAMS.
– Prove controls for silica: water suppression, on-tool extraction, effective RPE and supervision.
– Keep records in order: COSHH assessments, training, face-fit tests and health surveillance.
– Principal contractors will be pressed on coordination and monitoring of subcontractors’ methods.
Inside the focus on silica risk control
/> While legal duties on hazardous substance control have not been rewritten, the regulator’s priority appears to be consistent, practical delivery of controls that reduce airborne dust where it is generated. Site managers should anticipate inspectors observing cutting and drilling tasks, asking operatives about methods, and checking whether suppression systems are used correctly and maintained. There is likely to be attention on whether tight-fitting RPE is selected, face-fit tested, worn properly and kept clean, with contingency arrangements for facial hair and replacements. Health surveillance for workers engaged in regular high-risk activities may also come under the microscope, alongside evidence that supervisors challenge unsafe practices and stop work where controls are missing.
Documentation will still matter, but only insofar as it reflects what is happening on the day. Inspectors will expect RAMS and COSHH assessments to be specific to the materials and tools in use, identify reasonably practicable controls, and tie back to procurement (for example, ordering the right extraction shrouds, vacuums and water feed kits). They may ask how exposure has been considered at design and planning stages, such as specifying factory-cut products, offsite fabrication or alternative fixing methods that reduce dust. For consultants and clients, the message is that pre-construction information, design risk management and contractor selection should all reflect the reality that silica exposure remains a serious long-latency health risk.
# Caveats
/> The intensity of inspections and the exact lines of questioning can vary by region and site type, and not every project will experience the same level of scrutiny. No wholesale change to the legal exposure limits has been announced as part of this push, so the emphasis is on compliance with existing duties rather than new thresholds. Some sectors and tasks that generate little or no mineral dust may see limited direct impact, though principal contractors remain responsible for coordinating safe systems of work across packages.
What it means for contractors, clients and programmes
/> Operationally, the increased attention means programme and procurement decisions must lock in dust control as standard rather than “nice to have”. That includes allowing time for wet cutting set-up and drying, selecting tools with integrated extraction, and ensuring enough compliant vacuums and spares are on site. Supervisors will need the authority to delay or resequence tasks if controls are not available or effective. Record-keeping will need to be both tidy and truthful: face-fit testing logs, maintenance records for extraction, training matrices and health surveillance outcomes should be accessible and current. For clients and principal designers, demonstrating that dust risks were considered early will help show a joined-up approach if an inspection widens beyond the immediate workface.
Commercially, smaller subcontractors may face short-term costs to upgrade kit or tighten procedures, while principal contractors will be pressed to evidence how they monitor and support them. Cost plans may need contingency for consumables, filter replacements, RPE management and potential productivity dips associated with safer methods. None of this is new in principle, but the bar for “reasonably practicable” is being tested in real operations. Insurers and framework owners are also likely to watch how supply chains respond, potentially baking stronger requirements into prequalification and audits.
# A day on a medium-rise frame in the Midlands
/> A concrete frame crew is scheduled to saw-cut openings and chase services on three floors. The site manager halts the start until the extraction vacuums with appropriate filters arrive from stores and additional water feed hoses are set up. Operatives swap to tools with shrouded blades, and a trained supervisor checks RPE seals and records a toolbox briefing in the daily log. The work proceeds but runs into the afternoon, nudging follow-on trades to the next day; the planner updates the short-term lookahead. When an HSE inspector walks in mid-morning, they observe the task, review the RAMS against actual controls, and note the health surveillance entries for the crew.
# What to watch next
/>
– Whether HSE publishes further guidance or case studies clarifying expectations for common site tasks.
– How principal contractors adjust subcontractor onboarding and daily assurance around dust control.
– If clients and designers begin to mandate lower-dust methods or offsite options in tender documents.
– The extent to which insurers and public sector frameworks reflect silica controls in their requirements.
The momentum suggests tighter, more visible dust control is set to become a baseline expectation across UK sites. The key question now is whether supply chains can embed these practices without derailing programmes and budgets.
FAQ
# Is this a change in law or a shift in enforcement?
/> It appears to be a stronger enforcement focus on long-standing duties to control hazardous substances, rather than a new legal standard. In practice, that means inspectors will expect better evidence of effective dust control during work, not just compliant paperwork.
# Which activities are drawing the most attention?
/> Tasks that generate mineral dust are the obvious targets, such as cutting, chasing, drilling and breaking concrete, brick, block and stone. Ancillary processes like clean-up with vacuums and the maintenance of extraction systems may also be observed.
# What documentation are inspectors likely to ask for?
/> Inspectors commonly ask for COSHH assessments, RAMS, training records, RPE face-fit test evidence and health surveillance arrangements for relevant workers. They may also want to see maintenance logs for extraction equipment and how supervisors monitor compliance day to day.
# How could this affect small subcontractors?
/> Smaller firms may need to allocate budget for appropriate on-tool extraction, consumables and RPE management, alongside time for training and record-keeping. Principal contractors are likely to demand clearer evidence that controls are in place before allowing work to proceed.
# What timeframe should teams plan for increased scrutiny?
/> Industry reports suggest the focus is active now and could continue through upcoming inspection campaigns and spot checks. Teams should plan on the basis that unannounced visits may occur at any stage of a project, particularly when dust-generating tasks are underway.
