The short version
Respirable Crystalline Silica (RCS) Medicals monitor the respiratory health of workers at risk from silica dust. The assessment depends on the industry, worksite jurisdiction, exposure history and applicable scheme. KINNECT delivers RCS medicals nationwide, with the required tests, imaging, review and monitoring schedule confirmed against the relevant requirements.
The dangers of respirable crystalline silica.
Respirable crystalline silica (RCS) is a hazardous chemical commonly found in aggregates, mortar, concrete and stone. Regular inhalation can cause respiratory irritation, shortness of breath and asthma. Workers with frequent high-level exposure can develop acute silicosis , a progressive lung fibrosis that can cause severe shortness of breath and, in some cases, death.
Why it matters
Silicosis is one of the most serious occupational lung diseases in Australia today. Health monitoring is the early-warning system: regular spirometry, respiratory examination and chest imaging detect changes long before a worker would notice them, giving employers a chance to act on exposure controls.
KINNECT coordinates RCS monitoring programs across tunnelling, mining and construction. The reviewing practitioner must have the experience and qualifications required by the applicable health monitoring or mining scheme.
Work activities that typically require RCS health monitoring
Excavation, earth-moving & drilling
Operating excavators, drill rigs and earth-moving plant in soils and rock containing crystalline silica.
Stone & clay processing
Machine operation in clay and stone processing, including engineered stone fabrication and bench-top work.
Mining & mineral ore treating
Underground and open-cut mining, ore crushing, mineral processing and quarrying.
Construction labouring
General construction work, including paving, surfacing and dry brick, concrete or stone cutting.
Abrasive blasting
Sand and slag blasting operations, the blasting agent must not contain more than 1% crystalline silica.
Foundry casting
Foundry environments where moulds, cores and castings expose workers to respirable silica dust.
Pre-employment, periodic and exit, the full RCS lifecycle.
Crystalline silica health monitoring is a lifecycle program, not a one-off appointment. The baseline, periodic and exit requirements vary by scheme and exposure risk. Previous records support continuity but do not guarantee acceptance at a new site or in another scheme.
- 1Baseline
Pre-employment
Establish a baseline before silica-exposed work where required. The reviewing clinician checks exposure history and any previous assessments against the applicable scheme; imaging is not automatically required for every new worker.
- 2Framework and risk dependent
Periodic
Safe Work Australia guidance recommends annual examinations and spirometry; WorkSafe WA also recommends annual assessments and spirometry. Queensland mineral mine and quarry surveillance is required at least every 5 years where it applies, or sooner as advised. Imaging follows a separate risk-based schedule.
- 3Exit medical
Post-employment
Plan final monitoring under the relevant requirements and clinical advice. Safe Work Australia recommends a final examination; WA guidance includes exit monitoring with imaging exceptions. Queensland mineral mine and quarry exit surveillance is on request when retirement eligibility conditions are met.
What’s in a standard RCS medical
- Respiratory function and past exposure questionnaire
- Medical examination with focus on the respiratory system

Frequently asked questions about RCS medicals.
Who needs a Respirable Crystalline Silica medical?
Workers whose duties create a significant risk to health from respirable crystalline silica may need health monitoring under applicable WHS requirements. Examples include tunnelling, construction, stone processing, manufacturing, mining and quarrying. Mining schemes have their own scope and rules. Employers should assess the work and exposure risk, not assume every possible dust exposure triggers the same medical.
Which RCS medical do I need: National, Queensland or Western Australian?
Choose by the industry, worksite jurisdiction, duties, exposure history and applicable scheme, not the worker’s home address or appointment location. “National” refers to Safe Work Australia model health monitoring guidance, subject to the requirements adopted in the relevant jurisdiction; Safe Work Australia is not one national regulator. Queensland mineral mine and quarry workers fall under the RSHQ respiratory surveillance requirements where applicable; Queensland coal workers need the separate coal scheme. WA silica monitoring follows the applicable WA requirements. Provide KINNECT with the worksite state, industry (including coal versus mineral mining or quarrying), role, current and previous dust exposure, site requirements and previous medical records so the appropriate assessment can be confirmed.
What is the difference between the National, Queensland and WA RCS assessments?
National (model WHS guidance): For workplaces covered by applicable hazardous-chemical health monitoring duties. History, exposure records, respiratory examination and spirometry are central; the model guide recommends baseline chest X-ray and risk-based repeat imaging, with HRCT considered for high-risk workers. A registered medical practitioner experienced in health monitoring supervises the assessment. Reports go to the employer and worker, with regulator notification where required by the applicable law. See Safe Work Australia’s silica guidance.
Queensland (mineral mines and quarries): A sector-specific respiratory surveillance scheme, not a general Queensland medical. It includes chest examination, spirometry and an ILO-classified chest X-ray with independent dual-reading, plus further tests if needed. An Appropriate Doctor supervises and prepares the health surveillance report for the worker and site senior executive; prescribed disease reporting obligations also apply. See the Queensland mineral mine and quarry requirements.
Western Australia: Silica monitoring includes exposure and medical history, examination and spirometry, with low-dose high-resolution CT when indicated, rather than chest X-ray for silica screening. An engaged registered medical practitioner supervises monitoring; the worker receives the report, the employer receives outcomes and recommendations, and all silica health monitoring results are notified to WorkSafe on its form. See WorkSafe WA’s silica guidance. These frameworks are not interchangeable packages or guarantees of universal fitness for work.Does every worker in Queensland need the Queensland RCS assessment?
No. Living in Queensland or attending a Queensland clinic does not make the RSHQ mineral mine and quarry scheme applicable. That scheme covers workers in Queensland mineral mines and quarries; a documented site senior executive risk assessment may establish that very low current and previous respiratory exposure can be managed without surveillance. This is not an employer or worker simply opting out. Construction, manufacturing and other non-mining work must be assessed under the applicable WHS health monitoring requirements. Queensland coal mining has a separate scheme.
Is a Queensland RCS assessment the same as a Coal Mine Workers’ Health Scheme medical?
No. A Queensland mineral mine and quarry respiratory assessment is not the Coal Mine Workers’ Health Scheme (CMWHS) medical, often called a Coal Board Medical. Some respiratory tests and provider standards overlap, but the schemes have different scope, forms, review and reporting requirements. Under CMWHS, the employer appoints an RSHQ-approved Appointed Medical Adviser (AMA), who completes the health assessment report, including fitness for duty, restrictions and follow-up. A standalone RCS assessment does not replace it. See our Queensland Coal Board Medicals service and RSHQ’s coal worker guidance.
Can an RCS medical completed under one framework be used for another state or job?
Not automatically. Supply the previous assessment, spirometry, imaging and reports for review. The reviewing clinician must check their date, quality, exposure relevance, imaging protocol and reading standard, practitioner requirements and reporting against the destination scheme and role. Existing evidence may avoid unnecessary repeat tests, but extra tests, a new review or scheme-specific paperwork may be needed. Even an in-date medical is not a universal compliance or fitness certificate. Queensland mineral mine and quarry guidance allows continuity when changing employer or site if risks are unchanged and the next recommended surveillance date has not passed; that does not establish automatic transfer into coal or another jurisdiction.
How often should an RCS medical be conducted?
The schedule depends on the scheme and risk. Safe Work Australia model guidance recommends baseline monitoring, annual examination and spirometry, and a final examination when exposure ends; local requirements take precedence. Queensland mineral mine and quarry surveillance, where applicable, is required at least every 5 years, or sooner as advised by the Appropriate Doctor. WorkSafe WA recommends initial monitoring and annual assessments and spirometry. Imaging has a separate schedule: WA low-dose CT is generally 2-yearly for engineered stone workers after 2 years of significant exposure, or 5-yearly for other industries after 5 years, with earlier imaging if clinically indicated. Exit requirements and exceptions also vary by scheme.
What's included in a crystalline silica medical?
The assessment generally covers work and exposure history, a respiratory questionnaire, respiratory examination, spirometry and medical review. Chest imaging is selected when due under the applicable scheme and clinical advice: this may be an ILO-classified chest X-ray or low-dose CT, not a chest X-ray in every package. Previous results are compared where available. The required reviewing practitioner and report format depend on the scheme.
Do I need a chest X-ray or CT scan, and can my previous imaging be used?
It depends on the scheme, exposure history, when imaging is due and clinical findings. Safe Work Australia model guidance recommends a baseline chest X-ray and exposure-based repeats; five-yearly X-rays are recommended for lower-risk work during the first 20 years, with more frequent imaging or HRCT considered for higher risk. Queensland mineral mine and quarry surveillance includes an ILO-classified chest X-ray with independent dual-reading; CT may be needed for further investigation and is not an automatic substitute. WA uses low-dose high-resolution CT, not chest X-ray, for silica screening, with 2- or 5-yearly intervals according to exposure category. Workers new to the industry without prior significant dust exposure do not routinely need CT at entry under WA guidance. Provide previous images and reports: the reviewing clinician confirms recency, image quality, protocol and reporting suitability. A previous X-ray or ordinary diagnostic CT is not automatically accepted, and an annual medical does not necessarily mean annual imaging.
Is an RCS medical included in a standard pre-employment medical?
Do not assume it is included. A standard pre-employment assessment and silica health monitoring have different purposes; even a package containing spirometry may lack the required exposure history, imaging, scheme-specific review or reporting. Tell KINNECT that the role involves silica exposure and provide the worksite and scheme requirements. Confirm the requested assessment scope before booking. The reviewing clinician can assess whether previous pre-employment results are suitable, but they do not automatically satisfy an RCS monitoring requirement.
Who reviews and signs off the results?
The reviewing practitioner must meet the applicable scheme requirements, not just hold a generic occupational health title. Model WHS monitoring is carried out or supervised by a registered medical practitioner experienced in health monitoring; Queensland mineral mine and quarry surveillance is supervised by an Appropriate Doctor; CMWHS uses an employer-appointed, RSHQ-approved Appointed Medical Adviser; and WA monitoring is supervised by an engaged registered medical practitioner. The required practitioner, review and reporting arrangements must be confirmed for the selected assessment.
What happens if my RCS medical identifies an abnormal result?
An abnormal spirometry or imaging result needs clinical review; it does not automatically mean silicosis or permanent exclusion from work. The reviewing doctor assesses the result alongside exposure history and previous tests, explains the findings and arranges further tests or respiratory specialist review where needed. The doctor may recommend earlier monitoring, exposure restrictions or removal from silica work while concerns are investigated. Employers should act on recommendations and review exposure controls. Confirmed disease may require ongoing restrictions, and the relevant scheme’s reporting and notification obligations must be followed. Non-work-related findings may also need follow-up with the worker’s GP. Fitness and return-to-work decisions are individual clinical decisions, not guaranteed by this assessment.
Can KINNECT deliver RCS medicals onsite?
Yes. KINNECT delivers RCS medicals nationally through our owned clinics and vetted partner network, and mobilises clinicians onsite for larger workforces, remote sites and time-pressured periodic rounds.
