Experts have warned of rising numbers of Silica Dust Exposure in the UK
Silica dust and Silica Dust Exposure is a serious health hazard that can lead to a range of respiratory diseases, including silicosis. This condition is caused by the inhalation of tiny silica particles, which can become trapped in the lungs and cause inflammation and scarring. For workers in industries like construction, mining, and quarrying, exposure to silica dust is a significant risk.
The Dangers of Silica Dust
According to the Health and Safety Executive (HSE), silicosis is a serious and irreversible lung disease. It can cause a range of symptoms, including:
- Shortness of breath
- Coughing
- Chest pain
- Fatigue
- Weight loss
In severe cases, silicosis can lead to respiratory failure and death.
Silica Dust exposure is increasingly recognised as a serious and preventable health risk across UK workplaces. In particular, industries that involve cutting, drilling or polishing stone, concrete or engineered materials face heightened scrutiny from regulators and clinicians alike. As a result, employers are being urged to strengthen controls and, importantly, to ensure appropriate health surveillance is in place.
In this context, chest X-rays play a vital role. They support early identification of occupational lung disease, help employers meet legal duties, and ultimately protect workers’ long-term health.
What is silica dust and why does it matter?
Silica is a natural mineral found in materials such as sand, stone, concrete and mortar. When these materials are worked, fine particles—known as respirable crystalline silica—can be released into the air. Importantly, these particles are small enough to penetrate deep into the lungs when inhaled.
Over time, repeated exposure can cause silicosis, an irreversible and potentially fatal lung condition. In addition, exposure has been linked to chronic obstructive pulmonary disease (COPD), lung cancer and an increased risk of tuberculosis. Therefore, even relatively short exposure periods can have serious consequences if controls are inadequate.
Rising concern across UK industries
Recent clinical reports have highlighted a worrying increase in cases of silicosis among younger UK workers, particularly those working with high-silica engineered stone used in worktops and surfaces. In some cases, workers developed advanced disease after only a few years in the role.
Clinicians have warned that, much like historic asbestos-related diseases, silicosis may continue to progress even after exposure stops. Consequently, early detection and ongoing monitoring are essential.
As one senior UK respiratory researcher noted, the disease is increasingly affecting young men and has no effective cure once established. As a result, prevention and surveillance must be prioritised.

Who is most at risk?
While exposure can occur in many settings, certain occupations face a higher risk, including:
-
Construction and demolition trades
-
Stonemasonry and engineered stone fabrication
-
Quarrying and mining
-
Brick, tile and ceramics manufacturing
-
Foundry and metal casting work
In these environments, dust-generating tasks are often frequent and prolonged. Therefore, employers must assess risk carefully and act proportionately.
Why chest X-rays are a critical part of health surveillance
Chest X-rays are a recognised screening tool for identifying early lung changes associated with silicosis. Although they cannot reverse damage, they can detect abnormalities before severe symptoms develop. As a result, affected workers can be removed from further exposure and supported appropriately.
According to the Health and Safety Executive, health surveillance should be considered where there is a reasonable likelihood that disease may occur. In practice, this means that workers regularly exposed to respirable crystalline silica may require periodic imaging as part of a wider surveillance programme.
Importantly, the frequency of chest X-rays depends on exposure levels, duration of work and individual risk factors. Therefore, professional occupational health input is essential when designing a compliant programme.
Legal duties for UK employers
Under the Control of Substances Hazardous to Health (COSHH) Regulations, employers must assess, prevent or adequately control exposure to hazardous substances, including silica. Where risk remains, health surveillance becomes a legal requirement rather than a discretionary measure.
The current Workplace Exposure Limit for respirable crystalline silica is 0.1 mg/m³ over an 8-hour time-weighted average. However, even exposures below this limit may still warrant surveillance if risk is ongoing. Consequently, employers should not rely on limits alone to determine their responsibilities.
Further guidance is available directly from the HSE on managing silica risks and implementing surveillance programmes.
Practical steps to reduce risk
To protect workers effectively, employers should adopt a layered approach:
-
Engineering controls such as wet cutting and local exhaust ventilation
-
Administrative measures including task planning, training and exposure monitoring
-
Appropriate respiratory protective equipment, correctly fitted and maintained
However, even where controls are robust, health surveillance remains essential. This is because controls reduce risk but rarely eliminate it entirely.
How Latus Group supports employers
Latus Group provides comprehensive occupational health support to help businesses manage silica-related risks responsibly and compliantly. This includes mobile, on-site chest X-ray screening delivered as part of a structured health surveillance programme.
By bringing services directly to site, disruption is minimised and uptake is improved. In addition, digital radiography equipment provides high-quality imaging with very low radiation doses, ensuring both accuracy and safety.
Employers can integrate this service alongside other relevant support, such as occupational health assessments, management referrals and statutory surveillance programmes, all aligned with current UK guidance.
What workers can expect from an on-site chest X-ray
A typical on-site appointment is efficient and worker-friendly:
-
The scan itself usually takes around 10 minutes
-
Employees can return to normal duties immediately
-
Multiple workers can be screened in a single day
-
Results are reviewed and reported by qualified professionals
Following assessment, outcome letters are issued with clear guidance on continued participation in health surveillance where required. As a result, both employers and employees gain clarity and reassurance.
Why early action matters
Silicosis is preventable, yet once established it is life-changing. Therefore, early identification through appropriate surveillance is one of the most effective tools available to UK employers today. Chest X-rays, when used correctly, support informed decisions, regulatory compliance and, most importantly, long-term worker wellbeing.
For organisations where silica exposure is a concern, taking proactive steps now demonstrates good practice and a genuine commitment to health and safety.
