However, the issue extends far beyond one industry. Across manufacturing, construction, installation and product formulation activities, workers may be exposed to respirable dusts capable of causing serious and irreversible health effects. BASA has therefore issued guidance reminding employers of their responsibilities under the Control of Substances Hazardous to Health (COSHH) Regulations and the importance of effective exposure control.

Respirable dust consists of extremely small airborne particles that can penetrate deep into the lungs. Because these particles are often invisible to the naked eye and can remain suspended in the air for extended periods, workers may be exposed without realising the risk. Activities such as cutting, grinding, sanding, drilling, powder handling, mixing and certain construction or installation processes can all generate hazardous dusts. Where materials contain crystalline silica, exposure can create respirable crystalline silica, one of the most significant occupational health hazards currently facing industry.

The health implications are serious. Long-term exposure can lead to silicosis, chronic obstructive pulmonary disease (COPD), occupational asthma and, in some circumstances, lung cancer. Importantly, damage can develop over many years before symptoms become apparent, making prevention and exposure control essential. COSHH places a legal duty on employers to assess risks, prevent exposure where reasonably practicable, implement effective control measures and ensure that employees receive appropriate information, instruction and training.

A successful dust management strategy should start with reducing dust generation at source and applying the hierarchy of control. Engineering controls such as local exhaust ventilation (LEV), enclosed systems and water suppression can significantly reduce exposure. Good housekeeping practices are equally important, helping to prevent dust accumulation and secondary exposure. Where respiratory protective equipment (RPE) is required, it should be selected based on the risk assessment, correctly fitted, maintained and supported by user training. Employers should also consider whether health surveillance is necessary to identify potential occupational health effects at the earliest opportunity.

The recent focus on respirable dust serves as a timely reminder that workplace health risks are not always immediately visible. Effective dust control is both a legal requirement and a fundamental element of protecting workers. As BASA's guidance emphasises, healthy lungs are not optional, and a proactive approach to exposure management benefits employees, businesses and the wider industry alike.
