Occupational Health and Hygiene

Protecting worker health requires more than compliance it requires a clear understanding of workplace exposures, risk pathways, and practical control strategies. Confluence Environmental delivers science-led occupational health and hygiene services across NSW, supporting organisations to identify, assess, and manage exposure risks associated with airborne contaminants, hazardous substances, noise, vibration, biological agents, and indoor environmental quality. Our experienced occupational hygienists provide defensible monitoring, clear interpretation, and practical recommendations aligned with WHS regulations and industry best practice.

From baseline exposure monitoring and regulatory compliance to complaint investigations and high-risk project support, we help organisations protect workers, reduce long-term health risk, and make informed decisions about workplace controls.

Occupational Hygiene and Workplace Exposure Risk

Occupational hygiene is the science of anticipating, recognising, evaluating, and controlling workplace health hazards. Workers may be exposed to respirable dust, respirable crystalline silica, chemical vapours, fumes, biological contaminants, excessive noise, vibration, or poor indoor air quality often without visible warning. Through structured Exposure Risk Assessment, we evaluate exposure pathways, identify at-risk worker groups, and determine whether exposures exceed acceptable limits, forming the basis for practical and proportionate control strategies.

Our occupational hygiene services commonly support construction and demolition, manufacturing and industrial operations, property and facilities management, infrastructure projects, and government assets.

Respirable Crystalline Silica (RCS)

Respirable crystalline silica exposure remains one of the most significant occupational health risks in construction, demolition, tunnelling, quarrying, and manufacturing. Cutting, drilling, grinding, and disturbance of silica-containing materials can generate airborne particles capable of causing silicosis and other serious respiratory disease. Our Respirable Crystalline Silica services include task-based exposure monitoring, interpretation against workplace exposure standards, and development of practical engineering and administrative controls to reduce risk and support compliance with WHS requirements.

Hazardous Chemicals and Dangerous Goods

Workplaces that store, handle, or use hazardous chemicals must manage exposure risk and regulatory compliance carefully. Through our Hazardous Chemicals and Dangerous Goods assessments, we review chemical inventories, Safety Data Sheets, storage and handling practices, and potential exposure pathways to identify risks and recommend practical control measures aligned with WHS and dangerous goods legislation. These assessments support safe chemical management, worker protection, and regulatory readiness.

Noise and Vibration

Long-term exposure to occupational noise and vibration can lead to permanent hearing loss and chronic health effects. Our Noise and Vibration assessments evaluate exposure levels, identify high-risk activities and worker groups, and provide clear reporting and practical control recommendations to support compliance with occupational exposure standards and hearing conservation requirements.

Indoor Air Quality (IAQ)

Indoor air quality can significantly influence worker comfort, health, and productivity. Poor ventilation, contaminants, moisture, and building conditions may contribute to symptoms, complaints, or reduced performance. Our Indoor Air Quality investigations assess ventilation effectiveness, environmental parameters, and potential contaminant sources to identify underlying causes and recommend practical, proportionate corrective actions.

Mould, Moisture and Microbiology

Microbial growth within buildings is typically driven by underlying moisture issues such as leaks, condensation, or inadequate ventilation. Our Mould, Moisture and Microbiology investigations focus on identifying moisture sources, assessing the extent and likely impact of contamination, and guiding appropriate remediation and verification strategies to restore safe indoor environments.

Confined Spaces

Confined spaces present elevated atmospheric and physical hazards requiring structured assessment and control. Through our Confined Spaces services, we assist organisations in identifying confined spaces, establishing registers, assessing atmospheric and operational risks, and implementing practical procedures and control measures aligned with WHS legislation and safe work practices.

Clandestine Laboratories

Properties impacted by clandestine drug manufacturing can contain hazardous chemical residues and surface contamination requiring specialist investigation. Our Clandestine Laboratories assessments provide discreet evaluation, targeted sampling, and remediation guidance to support safe reoccupation and regulatory compliance.

Integrated Environmental and Hazardous Materials Expertise

Occupational hygiene risks often intersect with environmental exposure pathways and hazardous materials such as asbestos, contaminated soils, demolition dust, and chemical storage. Through our integrated Asbestos and Hazardous Materials and Environmental Services, Confluence Environmental provides coordinated assessment and risk management that aligns occupational health, environmental compliance, and project delivery.

Practical, Defensible Occupational Hygiene Solutions

Confluence Environmental provides comprehensive occupational hygiene services including exposure monitoring, respirable crystalline silica assessment, hazardous chemicals risk evaluation, noise and vibration assessment, indoor air quality and mould investigations, confined space risk assessment, clandestine laboratory contamination investigation, and regulatory compliance support. Our approach combines technical expertise, defensible monitoring, and practical recommendations to help organisations manage risk, protect worker health, and meet regulatory obligations.
