Theory: A systems approach to work health and safety management

This section defines key concepts for work health and safety (WHS) management.  It explains James Reasons’ Swiss Cheese Model of safety incident causation as a systems-based approach to WHS management; a model proposing that it is the combining of active failures (human errors) and latent conditions that lead to the WHS incidents that harm workers.  Subsequently, safety management systems are proposed as a mechanism to identify, and actively resolve latent factors, before introducing safety culture as fundamental to effective WHS management.
