What is going on

From 14 September 2026 the Wattle Creek plant runs a night crushing shift to fill a Hunter Roads Consortium order for 20 millimetre aggregate and road base. Conveyor CV03 has returned to service after its guard was refitted. The road base stockpile must be built and blended to specification, samples must be taken at the intervals on the quality plan, and the crusher must stay within its limits. The environmental authority restricts night noise and dust, and the crusher sprays and the stockpile shaping are part of the trigger action response plan. Any plant alarm, guard problem or dust exceedance must be recorded and reported to the Processing Superintendent.

Subject: Night crushing shift, control room and stockpiles

You are on the night crushing shift in the Wattle Creek control room from Monday. The plant has to produce 20 millimetre aggregate and road base to specification for the Hunter Roads Consortium order, and the road base stockpile needs to be built and blended without running the crusher outside its limits. Read the Environmental Policy dust section and the plant work instructions, take the samples at the intervals on the quality plan, log the stockpile tonnages, and record any plant alarm or guard issue in the Hazard and Incident Register. CV03 is back in service, so include it in your start-up checks.

Your brief

Carry out the control room start-up checks, run the crushing and screening plant within its limits, build and blend the road base stockpile, take and record the quality samples, and record any plant, guarding or environmental issue in the Hazard and Incident Register.

Work through it

You do not need to do it all. Doing a few of these will show you what the work is like. Your ticks and notes stay on this device.

Read the Environmental Policy dust and noise section and the plant work instructions and list the start-up checks for the control room, including CV03's guarding.
Check the status of the crusher, screens, conveyors and water cart in the Mobile Plant and Prestart Register and the Permit to Work and Isolation Register before starting, and note any open permit.
Set out the sampling intervals and the tests for the 20 millimetre aggregate and road base and record two sample results against the shift.
Describe how you build and blend the road base stockpile from the crusher output and the recycled material to meet the grading specification.
A crusher high current alarm occurs at 11:40 pm: describe your response and record it in the Hazard and Incident Register if it meets the reporting criteria.
The boundary dust monitor approaches its trigger level with the sprays running: state what the trigger action response plan requires and what you record.
Complete the shift report with tonnages produced, stockpile tonnage, samples taken and any issues for the Processing Superintendent.
