Welcome to Part Three of our series examining WCAT decisions involving a BC sawmill company. In this concluding episode, we analyze the most serious case in the series—WCAT Decision A2001896 (2021), where a workplace injury led to a $129,460 administrative penalty that was ultimately cancelled based on due diligence. **Case Overview:** - WCAT Decision A2001896 (December 10, 2021): Serious workplace injury involving planer equipment - Original penalty: $129,460 for lockout and safe work practice violations - Critical issue: Equipment left in "bypass mode" causing extended freewheeling of cutting heads - Final outcome: Penalty cancelled due to employer's comprehensive safety program and due diligence **Key Technical Issues:** - Bypass mode equipment settings and their impact on braking systems - The challenge of controlling kinetic energy in complex machinery - Administrative controls when complete energy isolation isn't technologically feasible - Importance of visual verification and safe distance procedures **WCAT's Due Diligence Analysis:** - 42 documented successful lockout procedures by the injured worker - Comprehensive training records and annual refreshers - Worker's active participation in writing safety procedures - Systematic approach to safety supervision and documentation **Educational Focus:** This episode examines how WCAT assesses due diligence when serious injuries occur, demonstrating that injury occurrence alone doesn't establish liability. We explore the legal framework for evaluating employer safety systems and the evidence required to demonstrate reasonable care. **Series Synthesis:** Drawing from all five WCAT decisions, we identify key patterns in due diligence assessment: - Comprehensive documentation and systematic safety programs - Proactive regulatory engagement and prompt compliance improvements - Understanding of specific regulatory requirements and technological limitations - Focus on reasonable care rather than perfect outcomes **Professional Insights:** - How bypass mode and similar equipment settings create hidden hazards - The role of administrative controls in managing residual risks - Building defensible safety management systems through systematic documentation - WCAT's approach to assessing employer safety efforts when injuries occur Remember, this AI-generated content is for educational purposes only—not legal or professional advice. **Resources:** - WCAT Decision A2001896: Equipment lockout and due diligence analysis - BC OHS Regulation Sections 10.3(1)(b) and 4.3(1)(b)(ii) - WorkSafeBC Prevention Manual Policy P2-95-1 (OHS Penalties) - WorkSafeBC Prevention Manual Policy P2-95-9 (Due Diligence)
