Dust Management at Woolloongabba

Dust levels are routinely monitored at our worksites, including at Woolloongabba, in the interest of workers’ health and safety and to ensure there are no adverse impacts to local residents or businesses.

This monitoring is subject to stringent conditions to ensure air quality complies with state and national requirements.

It forms part of an Air Quality Management Plan, which is a project requirement and is in place at the Woolloongabba worksite.

Monitoring points are both within and around the construction site and located to the north, south, east and west for full coverage.

This monitoring has consistently shown that the Cross River Rail project is compliant with all of its air quality requirements.

Recent issues

Issues relating to dust levels at Woolloongabba have been raised recently on 18 June and then again on 27 July.

Further to investigation of the 18 June issues, Workplace Health & Safety Queensland (WHSQ) attended site on 21 and 22 June 2021 and confirmed the following:

“WHSQ received a dust related complaint on 22 June 2021, we investigated the complaint including having one of our hygienists visit the site who undertook specific enquiries around the controls and readings.

“There was no non compliances identified in relation to this particular matter.”

On Tuesday, 27 July 2021 workers left an allocated work area due to dust from the TBM spoil conveyors and an onsite review was carried out to ensure all existing mitigation measures were in place and working effectively.

This was supported same day with additional monitoring conducted by an independent Certified Occupational Hygienist (COH), who confirmed no further controls were required for work to safely continue.

Additional mitigation measures were installed overnight regardless and as added precaution, including:

  • increased chemical dosage on conveyor spray to coagulate the dust
  • installation of additional duckbill water spray on the conveyor
  • shrouding over the start of the decline conveyor
  • installation of water mist sprays at conveyor transfer.

WHSQ attended the site on 28 July to review these mitigation measures, no issues were raised and work has resumed as normal on all parts of the Woolloongabba site.

The Cross River Rail Delivery Authority can reassure workers and nearby residents that stringent safety measures and controls are in place and there is no risk to health.

Independent sampling conducted at the Woolloongabba worksite has shown air quality on site meets stringent WHSQ requirements.

The safety of our workforce and the public is our top priority and control measures are continually reviewed and adjusted to ensure highest possible standards and continued best practice.

The Delivery Authority expects its contractors to continue to uphold the highest level of standards when it comes to meeting industry requirements, including dust mitigation measures such as using sprinklers to dampen spoil.
