Construction dust is not simply an inconvenience or a housekeeping issue. It is a serious occupational health hazard that can cause permanent, life-changing and potentially fatal lung disease. In May 2026, the Health and Safety Executive announced a nationwide inspection programme. HSE inspectors are expected to carry out more than 1,000 visits across Great Britain over a 12-month period, with enforcement action taken where businesses fail to meet the required standards. Businesses must identify hazardous dust, reduce its creation wherever reasonably practicable and demonstrate that suitable control measures are working in practice.
For contractors, site managers, health and safety professionals, installers and construction product specifiers, this is an important opportunity to review how dust risk is managed, not only while work is taking place, but from the earliest stages of design, procurement and material selection.
What is construction dust?
Construction dust is a broad term covering several types of airborne particles generated during building, refurbishment, maintenance and demolition work.vHSE identifies three principal categories of construction dust:
1. Silica dust, which can be released when materials such as concrete, mortar, sandstone, bricks and some tiles are cut, drilled, ground or otherwise disturbed.
2. Non-silica dust, which may come from materials containing little or no silica, including gypsum, cement, limestone, marble and dolomite.
3. Wood dust, which can be created when working with hardwood, softwood and manufactured products such as MDF or chipboard.
Not every type of construction dust presents exactly the same hazard. The level of risk depends on factors such as the material, the concentration of hazardous substances within it, the task being performed, the tools used, the duration of exposure and the effectiveness of the control measures. However, all construction dust should be treated as a potential health risk rather than merely an unavoidable by-product of the job.
Why is silica dust dangerous?
Regular or significant exposure to respirable crystalline silica can result in serious long-term respiratory disease. Conditions associated with silica exposure include:
Silicosis - Silicosis is an irreversible lung disease caused by inhaling respirable crystalline silica. The particles can cause inflammation and scarring in the lungs, reducing a person’s ability to breathe effectively. Silicosis often develops after prolonged exposure, but exceptionally high levels of exposure can cause the disease to progress much more quickly. There is currently no cure, making prevention particularly important.
Chronic obstructive pulmonary disease - Chronic obstructive pulmonary disease, or COPD, describes a group of progressive lung conditions, including emphysema and chronic bronchitis. COPD can cause persistent coughing, breathlessness, reduced mobility and long-term disability. Symptoms may worsen gradually, meaning the connection to workplace exposure is not always immediately recognised.
Lung cancer - Heavy and prolonged exposure to RCS can increase the risk of lung cancer. HSE describes silica as the biggest occupational cancer risk to construction workers after asbestos.
Why has HSE launched a silica dust inspection programme?
HSE’s current campaign follows growing concern about exposure to silica dust generated while fabricating engineered-stone products, including worktops used in kitchens and bathrooms. Engineered stone can contain high concentrations of crystalline silica. Activities such as cutting, shaping, grinding and polishing the material can release significant quantities of RCS if effective controls are not used.
On 11 May 2026, HSE announced new guidance stating that dry cutting of engineered stone is unacceptable. The regulator also launched a programme of more than 1,000 visits to fabricators across Great Britain over the following 12 months. In June 2026, HSE confirmed that four companies had already been issued with Prohibition Notices after inspectors found inadequate measures for controlling exposure. These notices required the affected businesses to stop the relevant work immediately and improve their safety arrangements before continuing. This demonstrates that the inspection programme is not simply an awareness campaign. Where inspectors identify an immediate or serious risk, formal enforcement action may follow.
How can material selection reduce dust?
Material selection can directly influence the amount of cutting, drilling, grinding and finishing required on site. When comparing construction products, specifiers and contractors should consider more than performance, price and availability. They should also examine how each product will be handled and installed. A material that supports a lower-dust working method can simplify site operations and complement the wider dust-control strategy.
How can Klasse G-board support a lower-dust installation method?
Klasse G-board has been designed with a score-and-snap cutting method. For suitable straight cuts, the board can be scored with an appropriate knife and snapped, reducing the need to use powered cutting tools for routine sizing. This can help minimise the amount of airborne dust created during the cutting stage when compared with installation methods that routinely rely on power saws. Choosing a score-and-snap sheathing board may offer several practical benefits:
- Less dust generated during suitable straight cuts.
- Reduced reliance on powered cutting equipment.
- Less demand on extraction for those cutting operations.
- A cleaner immediate working area.
- Reduced time associated with setting up cutting stations and extraction.
- Less settled dust requiring subsequent cleaning.
- A working method that supports the objective of controlling dust at source.
Is respiratory protective equipment enough?
RPE can play an important role, but it should not be the first or only control considered. Masks depend on correct selection, fit, use, storage and maintenance. Tight-fitting RPE must be suitable for the wearer, and face-fit testing is needed to confirm that the chosen model can form an adequate seal. Even correctly selected RPE only protects the person wearing it. It does not prevent dust from spreading through a building, exposing other trades, contaminating surfaces or creating additional cleaning requirements. Reducing dust at source, using suitable engineering controls and separating people from the hazard should therefore take priority. RPE is generally used as an additional safeguard where residual risk remains.
Can material selection improve dust control?
Yes. Choosing products and methods that require less powered cutting, grinding or finishing can reduce dust generation at source. Material selection should form part of the wider design and risk-management process. For sheathing applications, Klasse G-board’s score-and-snap capability offers a practical example of how product selection can help reduce reliance on power cutting for suitable straight cuts. It is a relatively simple change, but it reflects a much wider principle.
