Crystalline Silica in the Workplace
Understanding and Managing Risks of Crystalline Silica in the Workplace
Crystalline silica, a naturally occurring mineral found in materials like sand, sandstone, and concrete, poses significant health risks when its fine particles are inhaled. Both SafeWork NSW and WorkSafe Victoria emphasise the importance of managing these risks to protect workers from serious illnesses such as silicosis, lung cancer, and chronic obstructive pulmonary disease (COPD).
What is Crystalline Silica?
Crystalline silica is commonly found in construction and manufacturing materials. Activities like cutting, grinding, or drilling these materials can release respirable silica dust into the air, creating a hazardous environment for workers. SafeWork NSW highlights that exposure to this dust can lead to irreversible health conditions, including silicosis, which scars the lungs and can be life-threatening.
Managing Risks in the Workplace
WorkSafe Victoria provides specific guidance on controlling risks when handling silica flour, a powdered form of silica sand used in various products. Employers are urged to follow the hierarchy of control measures to minimize exposure. Key strategies include:
- Automation and Enclosure: Use automatic machines to handle silica flour and enclose areas where dust is generated.
- Dust Suppression Systems: Install and maintain effective dust extraction systems.
- Regular Cleaning: Use HEPA-filtered vacuums to clean work areas and prevent dust accumulation.
- Protective Equipment: Provide appropriate respiratory protective equipment (RPE) and ensure workers are trained in its use.
Why It Matters
The health risks associated with crystalline silica are severe but preventable. By implementing robust safety measures and adhering to guidelines from authorities like SafeWork NSW and WorkSafe Victoria, employers can create safer workplaces and protect their teams from harm.
