The Health and Safety Authority (HSA) regularly conducts national campaigns focused on silica dust exposure in the construction industry. These campaigns aim to raise awareness of the dangers associated with silica dust, including silicosis, lung cancer, chronic obstructive pulmonary disease (COPD), and other serious health issues.
Anyone in the construction industry – whether an employer or an employee – should take the time to understand this specific hazard and the impact it may be having on their workplace and their health.
The dangers of silica dust exposure
Exposure to respirable crystalline silica dust may occur during construction work involving stone, concrete, brick, and other sand-based materials, particularly during activities such as cutting, grinding, drilling, and demolition.
This exposure can cause a range of serious illnesses, including silicosis, lung cancer and chronic obstructive pulmonary disease (COPD). Silicosis is an incurable disease which causes damage to the lungs, and symptoms include persistent coughing, shortness of breath, and fatigue.
While symptoms may not manifest immediately, the effects of silica dust on employee health can be very serious. Employers have a legal responsibility to protect their employees from workplace hazards - and for those who employ construction workers, management of silica dust exposure should be a priority.
How to protect your employees from the dangers of silica dust
While awareness is crucial, and is certainly the first step to reducing risk, it’s also vital that business owners are equipped with actionable advice that can be used to protect their employees. Here are our top tips for protecting employees from the serious effects of prolonged silica-dust exposure:
- Risk assessments: The first step to reducing the risk of occupational disease is to conduct regular, comprehensive risk assessments. This goes for any Health & Safety hazard, particularly in high-risk sectors such as construction. Review these risk assessments annually, and whenever there is a change in workplace practices. This means that, if you introduce a new piece of equipment that will generate dust on your construction site, you should carry out a risk assessment for that piece of equipment.
- Control measures: It’s not enough simply to conduct a risk assessment and leave it at that. The most important element of the process is to analyse your findings and implement control measures to protect your staff from the risks you have identified. For example, do you require your employees to wear masks? Are those masks suitable for the use of silica dust? Does your machinery have built-in water suppression systems, on-tool extraction, or containment methods?
- Documentation and policies: Additionally, every business should have a Safety Statement that is accessible to employees and reviewed on a regular basis. If employees are not aware of the safety procedures that are in place, they will not be fully protected from workplace hazards. Your Safety Statement is an opportunity to establish and reinforce your safety policies, and to inform employees of the measures they should be taking while they work, such as appropriate use of respiratory protective equipment (RPE) and personal protective equipment (PPE).
- Training: Similarly, if employees are not trained in how to use equipment or to implement safety measures as they work, they will not be fully protected from hazards such as silica dust. It is vital that you regularly train your employees (including short-term or seasonal workers) in the correct usage of machinery and RPE.
- Health surveillance: Finally, our last piece of advice is to implement health surveillance. This is particularly important in industries with high risk of occupational disease, such as construction. Health surveillance involves regular and systematic health checks for your staff, aimed at detecting any early signs of work-related health issues. These findings can inform your business’ safety procedures, and the specific control measures you implement to protect your employees going forward.
