When you think about workplace hazards, what comes to mind? Heavy machinery, sharp tools, or maybe even slipping on a wet floor? While these are all important safety concerns, there's another hazard that's often overlooked: dust. Dust might seem harmless, but prolonged exposure can have serious health consequences, especially in industries like construction, woodworking, and automotive repair.
The Health Risks of Workplace Dust
Dust is more than just a nuisance; it's a significant health risk. Inhaling dust particles can lead to various respiratory issues, from minor irritations to severe conditions.
Breathing in dust can lead to various occupational illnesses and diseases, depending on several factors:
-
The size of the dust particles
-
The composition of the dust and how it affects the body
-
How concentrated the dust particles are in the worker’s breathing zone
-
How often and for how long a person is exposed to the dust
Most dust clouds contain particles of different sizes, and hazardous dust isn't always visible. The larger particles that can be breathed in are known as inhalable or inspirable dust. These can be seen with the naked eye and typically settle in the nose, throat, and upper respiratory tract. On the other hand, respirable dust consists of tiny particles that are invisible and can reach deep into the lungs.
Different dust particles have different health impacts. For instance, breathing in respirable crystalline silica dust can cause lung scarring, while inhalable lead dust can harm the central nervous system. Many occupational diseases develop after years of dust exposure, and symptoms may not appear until decades later.

Here are some common health problems associated with dust exposure:
-
Respiratory Issues: Inhaling fine dust particles can irritate the respiratory tract, leading to symptoms like coughing, sneezing, and shortness of breath. Over time, this can develop into more serious conditions such as chronic bronchitis or asthma.
-
Silicosis: This is a lung disease caused by inhaling silica dust, common in industries that work with materials like concrete, brick, or stone. Silicosis is a progressive and incurable disease that causes lung scarring and can lead to severe respiratory issues.
-
Lung Cancer: Prolonged exposure to certain types of dust, such as crystalline silica, has been linked to an increased risk of lung cancer. This risk is especially high in industries where workers are exposed to large amounts of dust over many years.
-
Skin and Eye Irritation: Dust can also cause irritation to the skin and eyes. Fine particles can settle on the skin, leading to rashes or dermatitis, and can cause discomfort or damage if they come into contact with the eyes.
Eliminating or Reducing Sanding-Related Risks
Eliminating Dust:
To eliminate or reduce dust hazards in the workplace, it's important to minimize the need for on-site sanding, cutting, and drilling, especially with materials that contain silica. While it's not possible to completely eliminate dust, confining its generation to controlled production environments can greatly improve safety. In the case of wood dust, putting in place dust extraction solutions can help eliminate on-site dust exposure, thus protecting workers from harmful effects.
Reducing Dust Exposure:
When eliminating dust is not possible, reducing exposure is essential. For silica dust, the first step is to monitor and assess the work environment to understand potential exposure levels. In factories and workshops, effective strategies include using engineering controls like enclosures, hoods, and local exhaust ventilation systems to capture dust at the source. Water suppression on fixed machinery can also help.
Wood dust can be effectively managed through on-tool extraction systems, which capture dust directly at the point of generation. We recommend using Medium Class dust extraction units with respiratory protective equipment to significantly reduce dust exposure. In vehicle repair workshops, a combination of personal protective equipment, on-tool extraction, and separation of sanding activities from other tasks can minimize dust-related risks.
Australian Workplace Standards and Health and Safety
In Australia, workplace health and safety is a top priority, and strict standards are in place to protect workers from hazards, including dust exposure. The Work Health and Safety (WHS) Regulations require employers to minimize the risk of airborne contaminants, which includes dust. Employers are obligated to provide a safe work environment, which involves implementing effective dust control measures.
Additionally, many on-site jobs in industries such as construction and manufacturing require specific certifications to ensure workers are knowledgeable about health and safety practices. This includes understanding the risks of dust exposure and how to use protective equipment effectively. Compliance with these standards is not only a legal requirement but also essential for protecting the health and well-being of workers.
Eliminating or Reducing Noise Exposure:
Training workers to use equipment correctly, installing noise shields, using noise-absorbing materials, and organizing work processes to reduce noise exposure can help with this. After implementing these measures, providing workers with appropriate hearing protection that fits well and suits their tasks is essential. Opting for tools with a lower noise level will significantly reduce noise pollution further.
Eliminating and Reducing Hand-Arm Vibration:
If it's practical to perform a job without using vibrating tools, those methods should be adopted to eliminate vibration risks. When vibration cannot be avoided, employers must take responsibility to reduce exposure to the lowest level reasonably possible. Workers should use low-vibration tools, maintain and repair tools regularly, and avoid prolonged tool use without breaks to minimize vibration exposure. Encouraging good blood circulation, such as keeping warm, avoiding smoking, and taking breaks to exercise fingers, is also crucial in preventing injury. Most Mirka sanders can be paired to an app that measures vibration to help control vibration exposure.
Addressing Psychosocial Risk Factors
Reducing negative psychosocial risk factors in an organization is essential for fostering a healthier workplace environmen. Effective strategies require commitment at all levels to address both physical and psychosocial risks. A holistic risk assessment approach, involving both management and the workforce, ensures that actual work activities are accurately evaluated. Open communication and collaboration are crucial for identifying risks and developing solutions, as imposed changes often lead to resistance and system failure. Regular review and reinforcement of these strategies are necessary to prevent a return to old habits.
Best practices for sanding activities
Risk assessments are legally required to ensure workplace safety. Without recognising the hazards associated with tasks like sanding—such as dust, noise, hand-arm vibration, and psychosocial risk factors—the risk of injury and long-term health issues increases.
It's crucial for employers to prioritise the safety and health of their workers, involving them in identifying hazards and developing safety measures. Engaged employees who feel valued are more likely to thrive and contribute positively to the workplace.
The Importance of Good Workplace Relationships and Culture
Engaging employees and maintaining open communication fosters better workplace relationships and a positive culture. These steps lead to meaningful change and a safer, healthier work environment.
