Stricter Regulations Regarding Crystalline Silica Substances Now in Force

Amendments to the model Work Health and Safety (WHS) regulations have been published by Safe Work Australia, designed to bolster protections for employees at risk of silica dust exposure across all sectors, particularly in building and construction.

Safe Work Australia said the amendments establish more stringent regulations concerning safety management of all materials that contain a minimum of 1% crystalline silica. Businesses handling these hazardous substances must now review their silica dust management plan against the updated requirements.

What Changes Have Been Introduced?

The federal regulatory body indicates changes to Work Health and Safety regulations will only be enforced in a jurisdiction once adopted into that jurisdiction's WHS legal framework. Construction firms operating across multiple states should confirm local adoption timelines before assuming national compliance applies uniformly.

Safe Work Australia points out that various resources are provided to assist persons conducting a business or undertaking (PCBUs) in recognising and complying with duties under the updated regulations. These duties centre on control measures, hazard identification, and ongoing management of silica-related risk within construction and manufacturing settings.

Why Silica Dust Poses a High Risk to Health

Crystalline silica dust remains a leading occupational health hazard for workers in stone cutting, tunnelling, and building trades. Prolonged exposure can cause silicosis and other irreversible lung conditions, making this a genuine high risk concern for employers and safety officers alike.

Effective management of this risk requires more than awareness — it demands documented controls, regular review, and clear accountability. Organisations should consult a Hazardous Materials Policy covering asbestos, lead, and silica to ensure practices align with current OHS obligations.

Key Safety Management Actions for PCBUs

• Identify all materials containing crystalline silica across construction sites and processing areas
• Implement control measures that reduce airborne dust and limit worker exposure
• Review and update health and safety documentation to reflect the amended WHS regulations
• Provide clear guidance to staff on hazardous substance handling and reporting
• Maintain records demonstrating ongoing risk management and OHS compliance

PCBUs already managing hazardous substances under existing frameworks, such as a hazardous substances checklist or register, will find these amendments build directly on established safety obligations rather than replacing them entirely.

Broader Context: A National Push for Stronger Protections

This update follows similar action taken across other jurisdictions. Victoria, for example, introduced its own regulations to protect workers from crystalline silica dust exposure, while NSW strengthened requirements for mines and petroleum sites under new WHS regulations. Together, these reforms signal a coordinated national approach to silica safety management.

For organisations building a comprehensive approach to hazardous substance management, a dedicated hazardous substances management plan offers a practical starting point for aligning site practices with current health and safety expectations.

Practical Steps Forward

Safety professionals in construction and manufacturing should treat these amendments as a prompt to audit existing controls rather than a compliance checkbox. Reviewing a guide to managing crystalline silica dust safety can help teams translate regulatory language into on-site action.

Businesses should also revisit their Hazardous Substances Policy to confirm it captures updated duties around silica-containing materials, particularly where manual handling and cutting processes intersect with dust generation.

Ultimately, robust safety management protects both workers and business continuity. Organisations that invest early in updated documentation, training, and control measures will find compliance far less disruptive than those waiting until enforcement catches up with practice.
