The Resources Regulator has become aware that services to clean, check and reuse removable diesel particulate exhaust filters (removable exhaust filters) on explosion-protected diesel engine systems (ExDES) that hold a registered design for use in underground coal mines are available. There are risks and legislative compliance issues associated with cleaning and reusing removable exhaust filters on ExDES. Although not prohibited, cleaning and reusing removable exhaust filters must not produce additional hazards or affect engine safety performance of the ExDES. That is, the cleaned removable exhaust filter must not:
- increase the fire or explosion risk
- reduce filter efficiency in diesel particulate capture
- release hazardous vapours or particles that may result in an increased risk to worker health.
The Resources Regulator has made a number of recommendations for both suppliers and mine operators. These recommendations should be considered as part of the overall management of risks associated with the potential hazards created when reusing removable exhaust filters.
