Recent legislative reforms and the transition to updated Workplace Exposure Limits (WEL) are reshaping the regulatory baseline for airborne contaminants across Australia. For occupational hygiene professionals, these changes demand more than updating compliance spreadsheets; they require a critical reassessment of exposure risk profiles, monitoring strategies, and regulatory interpretations.

This session will explore the practical and strategic implications of the revised WEL framework. Beyond the numbers, the webinar addresses the operational challenge of control verification, moving past assumed protection to evidence that exposure prevention controls perform as intended. Participants will learn defensible methods for evaluating and documenting “”So Far As Is Reasonably Practicable”” (SFAIRP) outcomes to align technical assessments with statutory due-diligence requirements. Finally, the session describes systematic methods for recording, reporting, and tracking control performance metrics over time, creating closed-loop assurance frameworks that transform routine monitoring data into reliable, auditable risk management.

Key Takeaways:

• Navigating WEL Reforms: Clarify the technical and legal shifts associated with the updated Workplace Exposure Limits and their direct impact on occupational hygiene practice.
• Control Verification in Practice: Establish practical protocols to verify the real-world implementation, integrity, and ongoing effectiveness of critical controls.
• Defensible SFAIRP Determinations: Understand structured documentation techniques to substantiate SFAIRP decisions and defend professional exposure judgements.
• Long-Term Assurance and Tracking: Implement auditable tracking and reporting mechanisms to monitor the performance of health exposure control longitudinally.
