Management of excavation, trenching and penetration risks Risk assessment A risk assessment must be completed in accordance with the WHS Hazard Identification and Risk Management Procedure () by any workers undertaking a work activity that involves excavations or trenching, for driving an object into the ground or for work activities where penetrations are made through walls, ceilings or floors. The following steps must be implemented to manage the risks associated with these activities: STEP 1 Hazard identification – Identify excavation, trenching or penetration activities and assess the location where they will be undertaken. STEP 2 Risk assessment: inherent risk – Assess the inherent risks associated with the work location and activity. STEP 3 Control risks – Identify and implement risk control measures. STEP 4 Risk assessment with control measures: residual risk – Assess the residual risks associated with these hazards following the implementation of the risk control measures. STEP 5 Monitor and review control measures – Review risk control measures to ensure they are working as planned. When undertaking the risk assessment, the following must be considered: all potential hazards (to workers, the public, assets, the environment etc.) the frequency and duration of to the hazard workers’ exposure the consequence of the hazard environmental conditions which may influence the work activity (i.e. wind, rain, temperature, etc.) legislative requirements hierarchy of controls that can eliminate or mitigate the hazard recommended or standard practices applied to similar circumstances at other Seqwater workplaces practicability of the available risk controls. Hierarchy of controls for managing risks The hierarchy of controls must be used to identify the most appropriate risk control measure to manage the risks associated with excavation, trenching or penetrations. The identification and selection of risk control measures must be undertaken in consultation with workers.
