2) The incident is a reminder that any work on hydraulic systems requires complete isolation and depressurization to avoid risks from high pressures, leaks, hose bursts, or whipping hoses.
3) The plant manager has initiated an investigation and notified staff to always follow correct isolation procedures when working on live hydraulic systems. Training will also be reviewed for those who work on such systems.
Risk management large epc projects
The document discusses risks associated with an underground metro project and strategies to mitigate those risks. It identifies key risks in engineering, construction, procurement, and execution phases. It analyzes specific risks that occurred, such as a diaphragm wall trench collapse and cavity formation in diaphragm walls. Mitigation strategies are proposed, such as modified excavation sequences, installation of bore wells, and micro-concrete grouting. Overall project risks are assessed using a risk matrix. Innovations to construction methods are also discussed to streamline utility diversion and reduce risks of soil collapse and sink holes.
Safety alert 10 corrosion of light poles 24 august 2018
An inspection uncovered significant corrosion below soil level at the base of street lamp poles at the Penrith Water Recycling Plant. Left unaddressed, further corrosion could cause poles to collapse, potentially injuring people or damaging assets. All metallic street light poles in contact with soil throughout the plant should be inspected, with barricades around any unsafe areas and work orders raised to repair or replace damaged poles. Corrective actions include ensuring light pole materials can withstand soil conditions and confirming preventative maintenance inspections of light posts are conducted.

Lessons learnt electrical incident penrith wrp july 2019
Workers were installing cable tray covers at a water recycling plant using a boom lift. While securing the final inclined cover in place with screws, one of the screws went through a live 240V cable, damaging the insulation. This caused a minor arc but no one was injured as they were standing on rubber matting. The live cable was then de-energized and further work was suspended pending an investigation. Key lessons included slowing down when tasks deviate from normal plans, reviewing site-specific risks in safe work method statements, and conducting audits to identify any electrical circuits still lacking residual current device protection.

Rail workers will continue using the Pegasus system and cards until their individual site transitions to MTA, which will be determined by site assessments from TfNSW Safety Managers. Rail workers should register for MTA, keep their Pegasus cards, and be informed of the transition through toolbox talks and site notices.
