Critical Risk Program

Keeping our people, contractors and communities safe by focusing on the controls that prevent serious injuries and fatalities.

Our critical risks and controls

Our Critical Risk Program focuses on 15 critical safety risks that have the potential to result in serious injury or fatality. The critical risks and controls below are the first to be published, with additional critical risks and controls to be added as they are formally endorsed.

Excavation and trenching

To eliminate the risk of harm to a person or service as a result of an impact to underground services or unauthorised access and engulfment in an excavation or trench

Critical controls Critical control objective
Detection of buried services To ensure that all active underground services are located, identified and marked at the excavation site and adjacent areas before allowing the excavation work to commence.
Safe access and egress To ensure a safe means of access and egress to a trench.
Stability of ground conditionsTo ensure ground conditions are assessed, maintained and controlled to prevent instability, collapse or loss of footing during activities.
Barricading and segregation To ensure effective barricading, segregation and exclusion zones are in place to protect workers and the public from hazards.
Emergency preparedness To ensure emergency equipment and trained workers are available to respond to all emergencies on the site.
