Silica Dust Exposure Monitoring

SafeSphere Consulting offers specialist Respirable Crystalline Silica Dust (RCS) monitoring and occupational hygiene services to help workplaces manage their dust exposure risks. An end to end solution of services are offered.

1. 

Workplace Auditing - We identify Respirable Crystalline Silica Dust hazards and high-risk tasks through workplace inspection audits.

2. 

Personal Exposure Monitoring - Conduct Respirable Crystalline Silica Dust exposure monitoring and provide NATA accredited analytical results to assess worker exposure risk and legal compliance. This may include statistical data review for longitudinal monitoring programs.

3.

Reporting of Assessment - We provide clear interpretation of silica dust monitoring results in comparison to statutory limits, identify high-risk tasks and assess effectiveness of current risk controls.

4.

Exposure Control Plans - Develop exposure control plans and procedures to address risk of Respirable Crystalline Silica Dust exposures and verify success of control measures through monitoring and review.

The risk of Silica Dust in Workplaces

Silica dust is a common hazard in industrial and construction environments. Respirable Crystalline Silica dust, or RCS, can be generated when cutting, grinding, or drilling materials such as concrete, stone, ceramics or bricks. Respirable Crystalline Silica is particularly dangerous because it can penetrate deep into the lungs when inhaled. Long-term exposure can lead to respiratory illnesses, including silicosis, lung cancer, and chronic obstructive pulmonary disease (COPD). Employers and workers must understand the risks and take appropriate precautions to limit exposure.

​

Effective management of respirable crystalline silica dust starts with identifying tasks and situations that generate it and conducting workplace personal monitoring to understand the severity of the health risk.​

Silica Dust (RCS) and WHS Law

In Australia, Persons Conducting a Business or Undertaking (PCBUs) have clear Work Health and Safety (WHS) legal obligations relating to silica dust, including respirable crystalline silica (RCS) under the WHS Act and WHS Regulations. PCBUs must:

  • Identify and assess tasks that generate silica dust, especially where materials contain 1% or more crystalline silica.

  • Undertake air monitoring if extent of exposure is not known.

  • Ensure worker exposures to respirable crystalline silica do not exceed the prescribed workplace exposure standard.

  • Eliminate or minimise workers’ exposure to respirable crystalline silica so far as is reasonably practicable.

  • Keep records and provide results to workers and SafeWork NSW when standards are exceeded. 

 

For high‑risk crystalline silica processes, PCBUs must register workers on the NSW Silica Worker Register and provide health monitoring and maintain documentation as required by law. Training, consultation and provision of control measures to reduce respirable crystalline silica dust exposure are also regulatory duties to protect worker health. Personal monitoring of workers exposure to RCS is a vital risk management component to understand the risk and measure effectiveness of silica dust control measures.

Other Airborne Contaminents

Other airborne contaminants can arise from various workplace activities such as cutting, grinding, welding, burning, spraying, or mixing dry products can create airborne hazards that threaten workers’ respiratory health if not properly understood and managed.

​​

Other potential airborne and dust exposure risks include:

  • Respirable and inhalable dusts

  • Welding fume and heavy metals

  • Diesel particulate matter (DPM), nitrogen oxides (NOx), sulfur oxides (SOx), carbon monoxide (CO)

  • Volatile organic compounds (VOCs) and isocyanates

  • Asbestos and other fibrous dust
