Why do slips, trips, and falls continue to happen—even when people are trained, signs are posted, and procedures are in place?

Join us for an engaging and thought-provoking webinar that flips the script on STFs. We’ll explore how systems thinking and Human Factors can reveal the why behind everyday performance—and stubborn risks like STF – especially when it doesn’t go as planned.

You’ll:

• Learn how the context of work shapes decisions and actions
• Apply tools to help understand the work system
• Explore real-world cases where task, organizational, and personnel workplace elements influenced the outcome
• Discover how a systems view can lead to stronger, more sustainable controls—not just more rules or surface fixes

This session features practical examples, audience participation, and a Safety II-informed perspective on one of the most persistent workplace risks.  We hope you’ll join us as we take a deeper look beneath the surface of STFs—and find new ways to create safer, more supportive work environments for all.

Speakers:

Heather Kahle, M.Sc. CRSP

Heather’s passion is helping shift the conversation—from LTIs to learning, from checking compliance to enabling capacity, from reacting to resilience, and from surface-level fixes to deeper system understanding.

With a Master’s in Human Factors and System Safety from Lund in Sweden, Heather brings a systems lens to expand perspectives. Her thesis (with Jenny Colman) on tree felling sparked a lifelong appreciation for why static rules can’t manage dynamic realities—and why listening matters more than lecturing.

Heather is now the Senior Lead, Human and System Interface with Seaspan’s Marine Standards Team, in Vancouver where she’s helping evolve learning from what goes right, systemic investigations, and audits to confirm the presence of capacity—not just the absence of failure. Recognizing feedback from our frontline is our most valuable fuel, Seaspan is shifting – seeing the rich, dynamic context that shapes work.

Before Seaspan, Heather spent 30 years with WorkSafeBC doing investigations, developing Regulation and supporting employers across BC with resources on slips & trips, fatigue risk, MSI prevention and preventing struck-bys—all with a system focus to advance understanding and effective prevention.  From the cobblestones of Sweden to construction sites, to shop floors and ship decks, Heather brings energy, insight, and curiosity. Expect a practical, Safety-II perspective to help expand from simple, surface fixes to stunning system shifts.

Jenny Colman M.Sc. CRSP, CCPE

Jenny earned her BSc.in ergonomics / human factors (HFE) at Loughborough University, UK where she specialized in forensic and system ergonomics. This background led to an 11 year opportunity in WorkSafeBC’s fatal and serious injury investigation division to analyze why an event occurred for the benefit of organizational and industry-wide learning. During that time, she earned her Masters of Science degree in Human Factors and System Safety at Lund University, Sweden.

She is currently working with the Prevention Risk Management Services at WorkSafeBC. In her current role she assists the teams, employers and workers in exploring various risks through practical risk assessment methodologies to promote injury reduction through a systems view.

The event will be free to attend for all members of ACE & other HFE Societies.
