Silica Dust Air Monitoring
Protect your workforce with professional silica dust air monitoring from Health Safety Consultants. Our experienced Occupational Hygienists provide respirable crystalline silica (RCS) monitoring and exposure assessments for mines, quarries, construction and industrial workplaces. Serving Sydney, NSW and the Central Coast, we deliver reliable exposure data to help you manage risk and meet WHS requirements.
What Is Silica Dust Monitoring?
Silica dust monitoring measures the concentration of respirable crystalline silica (RCS) in the air workers breathe. RCS can be generated when materials containing crystalline silica are cut, drilled, crushed, ground, sawn, polished or otherwise disturbed.
Silica-containing materials can include concrete, brick, mortar, natural stone, sandstone, tiles and other products. The finest respirable particles can become airborne and travel deep into the lungs, creating a serious occupational health risk.
Air monitoring provides objective exposure data to help determine whether workers are being adequately protected and whether existing dust controls are effective.
The Australian workplace exposure standard for respirable crystalline silica is 0.05 mg/m³ as an eight-hour time-weighted average (TWA). Where there is uncertainty about worker exposure, or monitoring is necessary to determine whether there is a risk to health, air monitoring may be required.
Why Is Respirable Crystalline Silica Monitoring Important?
Respirable crystalline silica can cause serious and irreversible health effects when workers are exposed to hazardous concentrations. Health risks associated with exposure include:
- Silicosis – an irreversible lung disease caused by scarring of lung tissue.
- Lung cancer – respirable crystalline silica is a recognised occupational carcinogen.
- Chronic obstructive pulmonary disease (COPD).
- Chronic bronchitis and emphysema.
- Other serious health effects, including potential kidney damage.
Fine silica particles may not be visible, so relying on what can be seen in the workplace is not enough to determine actual worker exposure.
Silica dust monitoring provides measurable exposure data that can be used to assess risk and verify the effectiveness of workplace controls.
When Is Silica Dust Monitoring Required?
Air monitoring can be an important part of managing silica exposure where there is uncertainty about worker exposure or where monitoring is needed to determine whether there is a risk to health.
Monitoring should be considered when:
- Workers perform high-dust activities such as cutting, drilling, grinding or crushing.
- New silica-generating processes, materials or equipment are introduced.
- Existing dust controls are changed or upgraded.
- Previous monitoring results are no longer representative.
- Work practices or workplace conditions change significantly.
- There is uncertainty about the level of worker exposure.
- Monitoring forms part of an ongoing mining or quarrying dust monitoring program.
For mines and quarries, additional monitoring requirements may apply under NSW mining safety legislation. Health Safety Consultants can assess your workplace and help determine an appropriate sampling strategy for your operation.
Personal & Static Silica Dust Monitoring
Health Safety Consultants can undertake personal and static silica dust monitoring, depending on the requirements of the workplace and the objectives of the assessment.
Personal Silica Exposure Monitoring
Personal air monitoring measures exposure within a worker’s breathing zone during normal work activities.
A calibrated sampling pump and cyclone are worn by the selected worker, with the sampling inlet positioned within the breathing zone. Sampling is undertaken while the worker performs representative duties, providing exposure data that relates directly to the conditions experienced by that worker.
Personal monitoring can be used to assess different workers, tasks and work areas and determine whether particular activities are associated with higher exposure levels.
Static Silica Dust Monitoring
Static or positional monitoring uses sampling equipment positioned at selected locations within the workplace.
It can help identify areas with elevated airborne dust concentrations, assess conditions around particular processes and evaluate the effectiveness of engineering and dust-control measures.
Static monitoring can complement personal exposure monitoring by providing additional information about workplace conditions, but it does not measure an individual worker’s breathing-zone exposure.
Silica Dust Monitoring for Mines, Quarries & Industry
Silica exposure can occur across a wide range of industries where silica-containing materials are processed, disturbed or handled.
Health Safety Consultants provides silica dust monitoring and occupational hygiene services for workplaces including:
- Mines and quarries – drilling, extraction, crushing, screening and processing.
- Construction and civil works – concrete cutting, drilling, grinding, demolition and masonry.
- Manufacturing – processes involving silica-containing materials.
- Stone processing – cutting, grinding and polishing.
- Demolition – disturbance of concrete, brick, masonry and other silica-containing materials.
- Infrastructure and tunnelling projects.
- Other industrial workplaces where workers may be exposed to respirable crystalline silica.
The appropriate monitoring program depends on the materials, processes, workers, existing controls and conditions at the workplace.
For applicable NSW mining monitoring programs, specific requirements can apply to dust sampling and the qualifications or licences of the person undertaking the sampling.
Our Silica Dust Monitoring & Testing Process
Health Safety Consultants takes a practical, risk-based approach to respirable crystalline silica monitoring. Our Occupational Hygienists assess the workplace, select appropriate sampling methods and interpret the results to provide useful exposure information.
Step 1: Workplace Assessment & Monitoring Plan
Before sampling begins, our Occupational Hygienists review your workplace activities, materials, processes, work areas and existing dust controls.
We identify representative workers and tasks and develop a sampling strategy designed to obtain meaningful exposure data.
Step 2: On-Site Air Sampling
Our Occupational Hygienists conduct personal or static air sampling using appropriate calibrated equipment.
Personal sampling equipment is positioned within the worker’s breathing zone while representative work activities are undertaken. Sampling conditions and relevant workplace factors are recorded to provide context for the results.
Step 3: Laboratory Analysis
Collected samples are submitted for appropriate NATA-accredited laboratory analysis to determine respirable dust and crystalline silica concentrations.
Where required, analysis can identify crystalline silica components such as quartz and cristobalite, providing reliable data for assessing worker exposure.
Step 4: Exposure Assessment & Reporting
Laboratory results are reviewed by our Occupational Hygienists and assessed against the applicable workplace exposure standard.
Our reporting explains the monitoring undertaken, results obtained and relevant exposure findings. Where appropriate, we identify opportunities to improve dust controls and provide practical recommendations to help reduce worker exposure.
