Noise reduction at Dampier

RIO Tinto Iron Ore recently reduced noise emissions from its Dampier operations.

Rio Tinto Iron Ore recently reduced noise emissions from its Dampier operations.

All fixed alarms, which must be sounded prior to the start-up of any machine or conveyor, on the Parker Point wharf were replaced with noise-reducing variable alarms.

The new alarms emit noise at only 5 dB above the ambient noise levels and can be heard from no more than 20 m away.

In addition, consultants were commissioned to investigate the noise levels associated with trains approaching and leaving the dumpers at Parker Point.

The consultants’ recommendations are being used to develop initiatives to further reduce noise emitted from the operation.
