Occupational hygiene is the science of identifying, assessing, and controlling workplace hazards that can affect worker health and safety. It focuses on preventing exposure to hazardous substances, physical agents, and environmental risks to create healthier and safer workplaces.

What Does Occupational Hygiene Cover?

Occupational hygiene includes the assessment and control of:

• Hazardous chemicals – including asbestos, lead, silica dust, and solvents

• Airborne contaminants – such as dust, fumes, vapours, and gases

• Noise and vibration – monitoring and reducing exposure to harmful levels

• Thermal stress – managing heat stress or cold exposure in workplaces

• Biological hazards – exposure to bacteria, viruses, and mould in certain industries

• Ergonomic risks – ensuring workplace design supports worker health

Why Is Occupational Hygiene Important?

Poor workplace hygiene can lead to long-term health effects, including:

• Respiratory diseases (e.g., asbestosis, silicosis, occupational asthma)

• Hearing loss from prolonged noise exposure

• Chemical poisoning or skin conditions

• Increased risk of workplace injuries and chronic illnesses

Who Regulates Occupational Hygiene in Australia?

Occupational hygiene is guided by:

• Safe Work Australia – develops national work health and safety (WHS) policies

• State and territory regulators (e.g., WorkSafe Victoria, SafeWork NSW) – enforce WHS laws

• Australian and international standards (e.g., AS/NZS 1715 for respiratory protection)

How Is Occupational Hygiene Managed in Workplaces?

• Hazard assessments – monitoring air quality, noise levels, and chemical exposure

• Control measures – using ventilation, PPE, and safer work practices

• Training and education – ensuring workers understand risks and how to manage them

• Health surveillance – regular monitoring for workers exposed to hazardous substances

Occupational noise refers to unwanted or excessive sound levels in the workplace that can cause hearing loss and other health effects over time. Industries such as construction, manufacturing, mining, and transport often expose workers to hazardous noise levels that exceed safe exposure limits set by Australian workplace regulations.

Why Is Occupational Noise a Problem?

Prolonged exposure to high noise levels can cause:

• Noise-Induced Hearing Loss (NIHL) – permanent damage to hearing

• Tinnitus – ringing or buzzing in the ears

• Stress and fatigue – increased workplace accidents due to reduced concentration

• Communication difficulties – making it harder to hear warnings or instructions

What Are the Workplace Noise Limits in Australia?

According to Safe Work Australia, employers must ensure workers are not exposed to:

• An 8-hour average noise level above 85 dB(A) (equivalent to a busy road or a lawnmower)

• Peak noise levels exceeding 140 dB(C) (such as a gunshot or explosion)

Which Workplaces Are Most at Risk?

High-risk industries for occupational noise include:

• Construction – power tools, heavy machinery, demolition work

• Manufacturing – machinery, stamping presses, conveyor belts

• Mining & Quarrying – drilling, crushing, transport equipment

• Transport & Logistics – aircraft, rail operations, truck driving

• Entertainment & Hospitality – live music venues, nightclubs, stadiums

How Can Occupational Noise Be Controlled?

To prevent hearing damage, workplaces should:

• Eliminate noise hazards where possible (e.g., using quieter machinery)

• Use engineering controls (e.g., sound barriers, enclosures, vibration damping)

• Implement administrative controls (e.g., rotating shifts to limit exposure)

• Provide hearing protection (e.g., earplugs, earmuffs) where noise cannot be reduced

• Conduct regular noise monitoring and hearing tests to protect workers' health

Be sure to discuss your occupational hygiene concerns with a Confluence Environmental Occupational Hygienist

What Are Hazardous Chemicals?

Hazardous chemicals are substances that can harm human health through exposure in the workplace. They may be toxic, corrosive, flammable, reactive, or carcinogenic, and can pose serious risks if not managed properly. These chemicals are commonly found in industries such as construction, manufacturing, agriculture, mining, and healthcare.

How Can Workers Be Exposed to Hazardous Chemicals?

Exposure can occur through:

• Inhalation – breathing in dust, fumes, vapours, or gases (e.g., silica dust, solvents)

• Skin contact – absorption through direct contact (e.g., acids, pesticides)

• Ingestion – accidental swallowing due to poor hygiene or contamination

• Injection – accidental punctures from contaminated objects (e.g., needlestick injuries)

What Are the Health Risks of Hazardous Chemical Exposure?

Short-term (acute) effects can include:

• Eye, nose, and throat irritation

• Dizziness, nausea, or headaches

• Skin burns or allergic reactions

Long-term (chronic) exposure can lead to:

• Respiratory diseases (e.g., occupational asthma, silicosis, asbestosis)

• Cancer (e.g., benzene, asbestos, formaldehyde exposure)

• Nervous system damage (e.g., lead, mercury, solvents)

• Reproductive and developmental issues

How Are Hazardous Chemicals Regulated in Australia?

Workplace hazardous chemicals are regulated under:

• Work Health and Safety (WHS) laws (Safe Work Australia & state regulators)

• Globally Harmonized System (GHS) of Classification and Labelling

• Exposure standards (e.g., Workplace Exposure Standards for Airborne Contaminants)

How Can Workplaces Manage Hazardous Chemical Risks?

Employers must:

1. Identify hazardous substances through Safety Data Sheets (SDS) and chemical registers.

2. Assess risks by monitoring exposure levels and workplace conditions.

3. Implement controls, including:

   • Substituting safer chemicals where possible

   • Using engineering controls (e.g., ventilation, containment)

   • Providing PPE (e.g., gloves, respirators, protective clothing)

4. Train workers on safe handling, storage, and emergency response.

5. Monitor worker health through regular medical surveillance.

What Is Indoor Air Quality?

Indoor air quality (IAQ) refers to the condition of the air inside buildings, including workplaces, homes, and public spaces. Poor IAQ can result from airborne pollutants, inadequate ventilation, or excessive humidity, potentially impacting health, comfort, and productivity.

What Are the Common Indoor Air Contaminants?

Indoor air pollution can come from various sources, including:

• Dust and particulate matter (PM) – from construction, combustion, or poor ventilation

• Volatile Organic Compounds (VOCs) – emitted from paints, cleaning products, and office furnishings

• Mould and biological contaminants – caused by damp conditions and poor ventilation

• Carbon monoxide (CO) and carbon dioxide (CO₂) – from heating systems, vehicle exhaust, and overcrowded spaces

• Asbestos and lead dust – from deteriorating building materials in older structures

Why Is Indoor Air Quality Important?

Poor IAQ can lead to short-term and long-term health effects, including:

• Headaches, dizziness, and fatigue

• Irritation of the eyes, nose, and throat

• Worsening of asthma and respiratory conditions

• Increased risk of chronic illnesses from prolonged exposure to hazardous substances

How Can Indoor Air Quality Be Improved?

To maintain good IAQ in workplaces and buildings:

1. Ensure proper ventilation – use natural airflow or mechanical systems to circulate fresh air.

2. Control humidity and moisture – to prevent mould growth.

3. Regularly inspect and maintain HVAC systems – to prevent dust and microbial buildup.

Crystalline silica is a naturally occurring mineral found in materials like sand, stone, concrete, and engineered stone. It is a key component in many construction and industrial materials, making it common in workplaces such as construction sites, quarries, and manufacturing facilities.

What is Silica Dust?

When materials containing crystalline silica are cut, drilled, ground, or crushed, they release fine, airborne particles known as respirable crystalline silica (RCS) or silica dust. These dust particles are so small that they can be inhaled deep into the lungs, where they pose serious health risks.

Diseases Caused by Silica Dust

Prolonged exposure to silica dust can lead to severe, often irreversible health conditions, including:

• Silicosis – A progressive, incurable lung disease caused by the buildup of silica particles in the lungs, leading to scarring and breathing difficulties.

• Lung Cancer – Crystalline silica is classified as a Group 1 carcinogen by the World Health Organization (WHO), meaning it is known to cause cancer in humans.

• Chronic Obstructive Pulmonary Disease (COPD) – Long-term exposure can lead to chronic bronchitis and other lung conditions that cause breathlessness and reduced lung function.

• Kidney Disease & Autoimmune Disorders – Silica exposure has been linked to kidney damage and conditions like rheumatoid arthritis and lupus.

Silica Dust in the Workplace

Workers in industries such as construction, mining, stone cutting, and manufacturing are at high risk of silica dust exposure. To reduce these risks, SafeWork NSW (the regulator) enforces strict regulations, including:

• Exposure Limits – The Workplace Exposure Standard (WES) for respirable crystalline silica is 0.05 mg/m³ (TWA 8 hours).

• Engineering Controls – Employers must implement dust suppression methods such as wet cutting, local exhaust ventilation, and enclosed processing.

• Respiratory Protection – Where engineering controls are not sufficient, workers must use fit-tested P2/N95 respirators.

• Training and Monitoring – Workplaces must conduct silica awareness training, regular air monitoring, and health surveillance for workers exposed to silica dust.

• Ban on Engineered Stone – Due to the extreme health risks, from 1 July 2024, the use of engineered stone was banned in NSW.

Confluence Environmental is specialised in silica testing and respirable crystalline silica dust air monitoring. Be sure to reach out to discuss your needs

Mould is a type of fungus that thrives in damp, warm, and humid environments. It reproduces by releasing tiny spores that can spread through the air and settle on surfaces. When given the right conditions, these spores grow into visible mould colonies.

What Does Mould Look Like?

Mould can appear in various colors, including black, green, white, orange, or brown. It often has a fuzzy, slimy, or powdery texture and commonly grows on walls, ceilings, carpets, wood, and other organic materials. It is frequently found in bathrooms, kitchens, basements, and any areas with persistent moisture.

Health Risks of Mould Exposure

Exposure to mould can pose significant health risks, especially for individuals with respiratory conditions, allergies, or weakened immune systems. Potential health effects include:

• Respiratory Issues – Inhaling mould spores can trigger asthma attacks, coughing, wheezing, and shortness of breath.

• Allergic Reactions – Symptoms such as sneezing, runny nose, red eyes, and skin rashes may develop in sensitive individuals.

• Irritation – Mould exposure can cause throat, eye, and skin irritation, even in those without allergies.

• Infections – In rare cases, mould can cause infections, particularly in people with compromised immune systems.

Preventing and Managing Mould Growth

To minimise the risks of mould, address moisture issues promptly. Ensure proper ventilation, fix leaks, and use dehumidifiers in damp areas. If mould is already present, professional assessment and remediation may be necessary to ensure safe removal.

If you’re concerned about mould in your home or workplace, contact Confluence Environmental for expert advice and assessment.

Lead-based paints are paints that contain 0.1% lead (w/w) or more, as defined by Australian standards. These paints were widely used in homes, commercial buildings, and industrial structures before the 1970s. While their use is now heavily restricted, older buildings in NSW may still contain lead-based paint, posing potential health and environmental risks.

Why is Lead-Based Paint Dangerous?

Lead is a toxic metal that can cause serious health problems, particularly in children and pregnant women. Exposure occurs when lead-based paint deteriorates, creating dust, chips, or contaminated soil. Inhaling or ingesting lead particles can lead to neurological damage, developmental issues, and other health complications.

Where is Lead-Based Paint Found?

• Homes and buildings built before 1970, especially on walls, doors, windows, and trims.

• Industrial and heritage buildings, including bridges and factories.

• Some old toys, furniture, and painted metal surfaces.

Managing Lead-Based Paint in NSW

The NSW EPA, SafeWork NSW, and local councils provide strict guidelines for handling lead-based paint. Key approaches include:

• Testing and Risk Assessment: Testing by a NATA Accredited laboratory can determine the presence of lead and the concentration expressed as a w/w%

• Safe Removal: Lead paint should never be dry-sanded or heat-stripped. Licensed professionals must follow SafeWork NSW guidelines for removal.

• Encapsulation and Sealing: In some cases, lead paint can be sealed with non-lead-based coatings to reduce risks.

Understanding the Hierarchy of Control

The Hierarchy of Control is a fundamental framework in Work Health and Safety (WHS) and occupational hygiene, designed to systematically manage workplace risks. It provides a structured approach to eliminating or minimising hazards, ensuring worker safety and compliance with SafeWork NSW regulations and the Work Health and Safety Act 2011 (NSW).

The Five Levels of Control Measures

The hierarchy consists of five levels, ranked from the most effective (elimination) to the least effective (PPE):

1. Elimination (Most Effective)

• Completely removing the hazard from the workplace.

• Example: Substituting a hazardous chemical with a non-toxic alternative or redesigning work processes to eliminate exposure.

2. Substitution

• Replacing the hazardous material or process with a safer alternative.

• Example: Using water-based paints instead of solvent-based paints to reduce exposure to toxic fumes.

3. Engineering Controls

• Implementing physical changes to the workplace to isolate or reduce exposure to hazards.

• Example: Installing local exhaust ventilation systems to control airborne contaminants in confined spaces.

4. Administrative Controls

• Implementing policies, procedures, and training to minimise risk.

• Example: Implementing job rotation to limit individual exposure to hazardous substances.

5. Personal Protective Equipment (PPE) (Least Effective)

• Providing protective gear such as gloves, respirators, and eyewear.

• Example: Ensuring workers handling asbestos wear P2 respirators and disposable coveralls.

Legal Requirements in NSW

Under the Work Health and Safety Regulation 2017 (NSW), businesses must apply the hierarchy of control when managing risks, particularly for hazardous substances, noise exposure, and airborne contaminants. SafeWork NSW enforces compliance through audits, guidance materials, and penalties for non-compliance.

Duty of PCBUs (Persons Conducting a Business or Undertaking)

• Identify hazards and assess risks.

• Apply the highest level of control reasonably practicable.

• Regularly review and maintain control measures to ensure effectiveness.

Why the Hierarchy of Control is Crucial in Occupational Hygiene

In occupational hygiene, effective hazard control protects workers from long-term health risks, such as respiratory diseases, chemical exposures, and ergonomic injuries. Applying the hierarchy of control ensures workplaces meet SafeWork NSW standards and create safer environments for employees.

Ensuring Compliance and Best Practices

• Conduct risk assessments regularly.

• Implement training and awareness programs for employees.

• Maintain compliance with WHS legislation and industry best practices.

• Engage certified occupational hygienists to assess and mitigate workplace hazards.

By adhering to the Hierarchy of Control, businesses can significantly reduce workplace risks, ensuring legal compliance and protecting worker health in alignment with SafeWork NSW guidelines.
