Product Overview

Summary: This Respirable Crystalline Silica Control SOP sets out a clear, practical framework for managing silica dust exposure in Australian workplaces. It helps businesses systematically identify high-risk tasks, implement effective controls, and demonstrate compliance with WHS laws and silica-specific regulations.

Respirable crystalline silica (RCS) is a major health hazard in many Australian industries, particularly construction, stonemasonry, civil works, mining, tunnelling, and manufacturing. Uncontrolled exposure can lead to silicosis, lung cancer and other serious respiratory diseases, creating significant legal, financial and reputational risk for businesses. This SOP provides a structured, evidence-based approach to controlling silica dust, aligned with current Australian WHS legislation and regulator expectations.

The document guides you through the full lifecycle of silica risk management: from identifying RCS-generating tasks, selecting appropriate engineering controls (such as water suppression and on-tool extraction), and specifying suitable respiratory protection, through to air monitoring, health surveillance and record keeping. It defines clear responsibilities for supervisors and workers, standardises safe work methods for cutting, grinding, drilling and polishing silica-containing materials, and embeds practical housekeeping and decontamination practices to prevent dust build-up and cross-contamination. For businesses under pressure to demonstrate compliance with silica reforms and prohibition of uncontrolled engineered stone, this SOP helps turn high-level obligations into day-to-day, auditable practice.

Key Benefits

• Ensure compliance with Australian WHS legislation and silica-specific regulatory requirements across relevant states and territories.
• Reduce worker exposure to respirable crystalline silica, lowering the risk of silicosis and long-term occupational disease claims.
• Standardise high-risk tasks such as cutting, grinding, drilling and polishing so that consistent, proven controls are always applied.
• Demonstrate due diligence to regulators, clients and insurers through documented procedures, monitoring and review processes.
• Improve workforce confidence and safety culture by providing clear instructions, training prompts and defined responsibilities.
