Bladder 2 Leak Detection Pit Inspections
-
Liquid in leak pit pH is less than 10 and free of dried caustic.
-
If the pit does contain liquid, is it below the inlet pipes?
-
Leak detection valve opened 100% and dry?
-
Liquid from leak detection pipe pH is less than 10 when the valve is opened.
-
Valve left in closed position once tasks have been completed.
-
Is the sump pump switched in the βONβ position?
South drain inspection
-
Southern drain free of any erosion damage or evidence of caustic leaching into the drain (water pH less than 9)
North drain inspection
-
Northern drain free of any erosion damage or evidence of caustic leaching into the drain (water pH <9)
Visual inspection of the ground around both bladders and pH checks of puddles using the pH strips (pH strips stock code 40116373)
-
Ground around the bladders free of contaminated puddles (pH <9), wet patches on embankments or dried caustic.
: Pump station and Orica transfer bund condition
-
Pump station bund inspected and free of visible cracks or concrete defects, equipment damage; missing flange covers/drain valves and spillages outside the bund (visual inspection only)
-
Orica transfer bund inspected and free of visible cracks, equipment damage; missing flange covers/drain valves and spillages outside the bund (visual inspection only)
Mechanical seal checks and reservoir tank (180PU10110)
-
Level (site glass) is full
-
Pressure reading is below 0
-
Temperature is below 60 degrees
-
Pump {180PU10110} is operational and available for use
Bladder #1 interceptor pit checks (also known as the weir)
-
Is the Bladder #1 interceptor pit/weir dry? If water is present, do a pH check with calibrated instrument to confirm pH between 6.5-9. If the pH is between 6.5 β 9, the valve can be opened to drain down. Valve to be closed following drain down. (Record Ph in notes)
