Silica dashboard

When not controlled, silica dust is a major hazard for workers in NSW. It can lead to the serious and often fatal lung disease silicosis. As part of SafeWork NSW’s Roadmap for NSW 2022, a five-year chemicals strategy has been developed that calls out silica as a top priority chemical. This dashboard shows what is being done.

Notification of a silicosis diagnosis

From 1 July 2020, all medical practitioners must notify NSW Health when they diagnose a case of silicosis in NSW.

Reducing exposure to hazardous chemicals and materials Project 2017-2022

Respirable Crystalline Silica (silica) is identified as one of the Top 2 Chemicals which pose the greatest risk to workers in NSW (the other being Formaldehyde). Aligned to SafeWork NSW’s Roadmap for NSW 2022, this project aims to achieve a 30% reduction in serious injuries and illnesses by 2022, in relation to dust exposure.  Key components of the project are Awareness and Education, Inspector Visits and Compliance, Legislation and Research into best practice approaches to harm prevention.

Action taken on uncontrolled cutting, grinding or drilling of silica products or materials

From 1 July 2020:

  • the workplace exposure standard (WES) for silica has been reduced to 0.05mg/m3 (eight-hour time-weighted average)
  • on-the-spot fines apply for uncontrolled cutting, grinding, drilling and polishing of manufactured stone
  • silicosis became a notifiable condition by all medical practitioners to NSW Health
  • on-the-spot fines apply for PCBUs failing to notify SafeWork NSW of an adverse health monitoring report

Uncontrolled cutting, grinding or drilling of products or materials containing crystalline silica can generate hazardous levels of airborne dust. Breathing in this dust, usually over several years, can lead to serious and fatal lung diseases such as silicosis. You must use water, dust extraction systems on portable tools, or adopt other methods that eliminate or minimise the generation of silica dust. Inspectors can issue prohibition notices to stop you from doing work that generates high levels of silica dust. If you don't comply with a prohibition notice, PCBUs (employers) can face penalties up to $100,000.

If you are a fabricator or installer of manufactured stone products e.g. kitchen benchtops you must:

  • use saws, grinders and polishers with an integrated water supply to minimise the amount of dust generated
  • ensure workers wear half face piece reusable or disposable respirators as a minimum, that comply with the Australian Standard 1716:2012 Respiratory Protective Devices
  • use on-tool dust capture shrouds or water to control dust generated during any work required during on site installation.

Failure to use these controls for fabricating or installing manufactured stone can result in an on the spot fine of $3,600.
