Contact SESA occupational hygiene team for crystalline silica dust monitoring and testing services in Sydney, NSW and ACT.

The Critical Dangers of Respirable Crystalline Silica (RCS)
Crystalline Silica Air Monitoring is not just a regulatory checkbox; it’s a vital first line defence against a serious occupational health hazard. When materials like natural stone, concrete, engineered stone benchtops, and mortar containing >1% crystalline silica are cut, crushed, or drilled, they generate invisible respirable dust particles. These particles are small enough to be inhaled deep into the lungs, where they can cause irreversible and potentially fatal diseases.
A comprehensive Silica Exposure Assessment is the first step to mitigating these risks, which include but not limited to:
- Silicosis: An incurable and progressive lung disease that causes scarring and stiffening of the lungs.
- Lung Cancer: Proven links to prolonged exposure to Respirable Crystalline Silica.
- Chronic Obstructive Pulmonary Disease (COPD).
- Kidney Disease.
For mines, quarries, manufacturing and construction sites, the health of your workforce is your greatest asset. Our Silica Dust Air Monitoring provides the critical data needed to protect them, demonstrating due diligence and compliance with Work Health and Safety (WHS) Legislation.
Why Choose an Occupational Hygienist from a Licensed Provider for Dust & Silica Air Monitoring?
Accurate Silica Dust Air Sampling is a complex process where expertise matters. While others may offer basic sampling, only a Licensed provider with experienced Occupational Hygienists possesses the advanced training and legal authorisation to deliver a fully compliant and defensible Silica Exposure Assessment. Choosing SESA ensures:
- Regulatory Assurance for Mines & Quarries: Our dust air sampling licence from the NSW Resources Regulator is a mandatory requirement for this high-risk sector, guaranteeing our work meets the strictest standards.
- Scientific Rigour: We don’t just take samples; we conduct a thorough assessment. This includes analysing work practices, evaluating existing control measures, and ensuring sampling is performed under correct, representative conditions—a core principle of effective Crystalline Silica Monitoring.
- Actionable Insight Beyond Data: You receive more than just a number. Our certified experts interpret the results against exposure standards and provide clear, practical recommendations to reduce risk and protect your team, ensuring your safety measures are both effective and compliant.
By partnering with SESA, you gain more than a test result; you gain a partner dedicated to achieving the highest level of workplace safety and regulatory compliance.

Our Proven Silica Dust Air Monitoring & Testing Process
At SESA, we believe in a clear, systematic approach to Respirable Crystalline Silica (RCS) Monitoring. Our proven process, developed by Certified Occupational Hygienists and verified by the Resources Regulator, ensures accuracy, compliance, and actionable results from start to finish.
Step 1: Comprehensive Consultation & Planning
Before any sampling begins, our expert hygienists consult with you to understand your specific operations, work areas, and concerns. We develop a tailored sampling strategy that targets the highest-risk tasks and ensures our Silica Exposure Assessment is both efficient and representative of true worker exposure.
Step 2: Precise On-Site Air Sampling by Experts
Our Licensed Occupational Hygienists conduct the on-site air sampling using state-of-the-art calibrated equipment. Our sampling equipment are calibrated under our NATA (National Association of Testing Authorities) accreditation for air volume measurements. We focus on capturing data during typical work activities, ensuring the results accurately reflect the levels of respirable dust your team encounters. This hands-on expertise is critical for a reliable Silica Dust Air Monitoring outcome.
Step 3: Accredited Laboratory Analysis
The collected samples are sent to a NATA-accredited laboratory for precise Respirable Crystalline Silica Testing and licensed by the Resources Regulator to analyse the samples. This independent, quality-assured analysis is the gold standard, providing you with definitive, legally-defensible data on airborne respirable crystalline silica concentrations including Quartz, Cristobalite and other RCS as required for the assessment.
Step 4: Clear, Actionable Reporting & Recommendations
You don’t just receive a lab report. We provide a comprehensive summary that clearly states exposure levels, assesses them against Safe Work Australia exposure standards, and provides practical, prioritised recommendations for improving controls and ensuring compliance. Our goal is to give you a clear roadmap to a safer workplace.

Silica Dust Monitoring FAQs
On-site sampling usually takes a day for a single shift, depending on site size and tasks. From consultation to the final report, the full process typically takes 10–15 business days, including sample analysis at a NATA-accredited lab and report compilation with actionable recommendations.
Costs depend on the number of workers, tasks, monitoring duration, and site complexity. We provide transparent, upfront quotes after a brief consultation. For standard assessments of multiple high-risk tasks, contact us for a tailored, obligation-free quote.
Our reports include a clear action plan with practical recommendations to reduce exposure immediately, such as engineering controls, administrative changes, or personal protective equipment (PPE) as immediate control until other control measures higher in the hierarchy are implemented. We also advise a follow-up assessment to ensure controls are effective and compliance is maintained. Exceedances of the exposure standards are to be reported by the mines and quarries to the Resources Regulator.
Frequency depends on results and operational changes and regulatory requirements. Annual monitoring is common if exposure is controlled, but assessments should be repeated whenever processes, materials, equipment, or controls change. Our hygienists will recommend a suitable ongoing schedule during the initial assessment. For mines and quarries, annual monitoring is required annually.
Yes. We provide tailored, cost-effective packages that focus on high-priority tasks for smaller teams, ensuring essential compliance data without unnecessary expense. Our aim is to make professional occupational hygiene services accessible to every workplace.
