Respirable crystalline silica audit campaign report: Stage 3

Audit campaign focus

To ensure workers are being protected from the risk of silicosis, Workplace Health and Safety Queensland (WHSQ) inspectors audited all 158 (known) stone benchtop fabrication workplaces between August 2020 and May 2021.

Since 2017, 238 workers in the stone benchtop fabrication industry have been diagnosed with silicosis due to occupational exposure to respirable crystalline silica (RCS).

This was the third in a series of compliance audit campaigns undertaken by WHSQ, targeting RCS exposure control and worker health monitoring in the stone benchtop fabrication industry. Workplaces were assessed against the requirements of the Managing RCS dust exposure in the stone benchtop industry Code of Practice 2019 (the Code) which commenced on 31 October 2019.

To help businesses comply with the new requirements, before the audits, workplaces were provided with a copy of the Code, plus guidance and information on how to manage RCS risks.

Enforcement actions

Inspectors completed 233 site visits and took 368 enforcement actions to address non-compliances consisting of:

• 302 improvement notices
• 27 infringement notices (totally $79,920 in fines)
• 24 prohibition notices
• 12 immediate compliances (issues resolved during the inspection)
• two electrical safety notices
• one notice to produce documents.

Key non-compliant findings

Inspectors identified the following key non-compliance issues:

Managing RCS risks to workers and others

Since 1 September 2024, stronger regulation the around the processing of crystalline silica substances (CSS) has been in place. CSS is defined as any material containing at least one per cent crystalline silica by weight.

Should the material you are working with be a CSS, please refer to the Working with crystalline silica substances: Guidance for PCBUs (PDF, 2.29 MB) for information on how best to comply with regulatory requirements and to manage the risks of RCS.
