Did you complete a verification on Trains (departing mines and at the ports)
Review planned trains in for current shift in Holistic Operating System DI (HOS DI) and compare the moisture levels against the mine’s Dust Extinction Moisture (DEM) limits, are they below the DEM?
Are more than 90% of trains departing to the ports above their DEM level? (review previous months data)
Do they know how to check inbound train moisture levels?
Have they checked the dust risk forecast for the shift?
Are they able to explain the controls available to them to manage the risk? (e.g. conveyor sprays maximum setting, deluge sprays, assign an operator to manually hose product on conveyor etc).
Choose a mine - Is the utilisation rate of train load out sprays >90%?
No community complaints related to dust from trains have been recorded in the last 90 days?
Baghouse / Dust Collector (crushing / screening)
Did you complete a verification on a screenhouse or crushing baghouse / dust collector?
Select two or three maintenance orders. Were they completed and time confirmed?
Log into the HMI system (Wonderware / CITEC) and review the operational status of ≥2 of the site baghouses - are they operational without any alarms or problems?
Review two or more completed entries in the site bridging and bypass register. Are they filled in correctly, have appropriate controls and are endorsed by the Registered Manager?
Did you complete a verification in the stockyard?
Are the video cameras being used by the OC controllers for dust mitigation decisions? (contact OC controller and ask)
Key cameras are clean and unobstructed (provide good visibilty of stockyard area)
Did you complete a verification on conveyors?
Review a selection of belt scraper maintenance tactics: are they completed and time confirmed?
High Pressure Low Volume belt washer flow rates are within their design range (>20L but <60L per minute)?
Balanced Machines (stakcers, reclaimers, shiploaders)
Did you complete a verification on bulking activities?
Review operational inspections – are the balanced machine daily inspections being completed?
Is there any maintenance notifications assigned against dust suppression equipment?
Roads and Open Areas
Did you complete a verification on road and open areas?
Is there a maintenance prioritisation process at the MEM workshop for water carts and street sweepers?
Has the ESO team undertaken speed compliance checks within the plant or stockyards within the previous three months?
Documentation / Metrics / Monitoring
Did you compelte an inspection at the Train Load Out facility?
Is the daily dust risk forecast reviewed at operational / maintenance prestarts?
Is the public dust website operational? (ports only)
(web link: http://vdv.benchmarkmonitoring.com.au/vdv/vdv_gmap.php)
Are the site licenced air quality monitoring stations operational and have recorded >90% uptime (previous 3 months)?
