Serious incident investigations into accidents involving failures in energy isolation continue to highlight the same underlying issue: work taking place within systems that were believed to be safe, with permits, procedures, and isolations apparently in place.

This recorded webinar explores why that happens.

In many investigations, the same conclusions appear: checks were missed, communication broke down, or procedures weren’t followed. The typical response is more training, more checks, and more emphasis on compliance.

But when similar situations keep happening, it forces a difficult question—are we really getting to the heart of the problem?

Using real accident examples, this recorded webinar shows why conventional explanations often stop too early—and how a broader human factors perspective can help organisations better understand and improve the conditions in which isolation decisions are made.

Is this recorded webinar for you? If you’ve ever asked yourself…

  • Are our isolation systems truly reliable in practice, or do they only look robust on paper?
  • Why do experienced people still get caught out during energy isolation work?
  • Are missed checks and communication failures really the cause—or just the visible symptoms?
  • How do shift handovers, supervision, production pressures, and team roles affect isolation safety?
  • Do our procedures help people understand the wider system, or just tell them what steps to follow?
  • How can we better identify the difficult decisions people face during isolation and maintenance work?

…then this recorded webinar is for you.

What You Learn in This Recorded Webinar

Why isolations fail in practice

How hazardous situations still develop despite permits, procedures, and formal isolation steps being followed.

The limits of familiar explanations

Why “checks failed”, “communication failed”, and “procedure not followed” often describe the event without really explaining it.

A human factors journey

How thinking has evolved from simple “human error vs technical failure” explanations, through Reason’s well-known models, to a broader systems view of work.

What real case studies reveal

How factors such as task conditions, experience, fatigue, role assumptions, leadership style, and missing support combine to shape what actually happens on site.

A more effective way to improve isolation safety

How human factors and critical task safety analysis techniques can be used to better understand work in context—and strengthen how isolation is managed in practice.

Whether you are responsible for maintenance, operations, engineering, permits, or health and safety, this webinar offers a more realistic and practical way to understand why safety isolations fail—and what can be done to make them more reliable in the real world.
