Incident Investigation Process

Use the Incident Investigation Process as an analysis tool to help identify factors that contribute to injuries in your workplace, and find the right prevention solutions.

How does it work?

The Incident Investigation Process helps you to trace an ‘event’ – a workplace injury, illness or death – back to several causal factors, rather than a single cause. The model helps you to consider a range of factors that could have contributed to the event occurring, and you can see it in action in three case studies below.

Cultural factors

Safety culture is ‘the way we do things around here’. It’s the collective practices shared by everyone in the workplace to reflect what’s important.

Task factors

Task factors – the actions and movements used by people to perform their work – can have an impact on the health and safety of your business.

System factors

Systems – or lack of systems – shape the working environment and influence how a worker may act.

Case studies

Three scenarios which show how the Incident Investigation Process can be used to identify factors that contributed to a workplace injury.

How the Process works with the Health and Safety Improvement Cycle and ACC workplace safety programmes

The Incident Investigation Process can be used alongside the Health and Safety Improvement Cycle and ACC’s other workplace safety programmes to help keep your business injury-free.
