Isolation issues identified at mines
The Resources Regulator has issued several recommendations after inspectors identified issues with the implementation, use, and supervision of isolation systems used for the management of risk associated with plant and equipment at coal mines.
During planned inspection activities, inspectors observed activities including maintenance and repair activities of plant. Those maintenance activities require isolation of energy to some extent, whether for part of the plant or the entire plant. For large maintenance tasks, these isolations need to cover multiple workers and are often required to be in place over multiple shifts. This is usually managed through the use of permits.
Observations of the implementation and operation of the permit isolation systems have identified deficiencies at many of the operations where they are in use.
