Many Australian employers focus on managing visible workplace hazards. Yet, airborne contaminants remain among the most significant and often overlooked risks across industries, including construction, manufacturing, transport, healthcare, laboratories, mining, and warehousing.
To strengthen workplace health protections, Safe Work Australia is replacing the current Workplace Exposure Standards (WES) framework with a new Workplace Exposure Limits (WEL) framework for airborne contaminants.
While businesses must continue complying with existing WES requirements until 1 December 2026, organisations should start preparing now. This transition presents an important opportunity to review workplace health risks, strengthen control measures, and ensure compliance well before the new limits take effect.
What Are Workplace Exposure Limits?
Workplace Exposure Limits (WELs) define the maximum concentration of airborne contaminants that workers can be exposed to during workplace activities without adverse health effects.
These contaminants can include:
- Dusts
- Fumes
- Mists
- Vapours
- Gases
- Hazardous chemicals
Exposure above these limits can lead to serious health conditions, including:
- Occupational asthma
- Silicosis
- Chronic respiratory disease
- Lung damage
- Certain cancers and other long-term illnesses
Employers have a legal duty to ensure workers and other persons in the workplace are not exposed to airborne contaminants above the applicable exposure limits.
What Is Changing?
Effective 1 December 2026, Australia will adopt the new Workplace Exposure Limits framework. Until then, businesses must continue to comply with the current Workplace Exposure Standards.
While the change may initially appear administrative, updated exposure limits can have significant implications for workplace health and safety management, including:
- Hazardous chemical management
- Air monitoring requirements
- Risk assessments
- Safe work procedures
- Personal protective equipment (PPE)
- Health monitoring programs
- Contractor management processes
Organisations that delay preparation may face considerable operational, compliance, and financial challenges as the implementation deadline approaches.
What Employers Should Do Now
1. Conduct a Comprehensive Risk Assessment
The first step is to identify where airborne contaminants may be present within your operations.
This should include:
- Consulting with workers and health and safety representatives
- Reviewing Safety Data Sheets (SDS)
- Identifying hazardous substances used, handled, or generated
- Assessing existing exposure controls
- Reviewing historical air monitoring results
Workers often have firsthand knowledge of tasks or processes that generate dust, fumes, or vapours, making consultation a critical component of effective risk management.
2. Review and Strengthen Existing Controls
Employers should evaluate current controls using the Hierarchy of Controls to determine whether risks can be eliminated or further reduced.
Consider whether existing measures remain effective, including:
- Substituting hazardous materials with safer alternatives
- Engineering controls
- Local exhaust ventilation systems
- Process isolation or enclosure
- Administrative controls
- Respiratory protective equipment
Importantly, PPE should not be the sole control measure where more effective solutions are reasonably practicable.
3. Engage Occupational Hygiene Specialists
For workplaces where hazardous airborne contaminants are present, specialist support may be valuable.
Occupational hygienists can assist with:
- Workplace exposure assessments
- Air monitoring programs
- Interpretation of monitoring results
- Evaluation of control effectiveness
- Compliance planning and implementation
For higher-risk industries, expert advice can significantly reduce both worker health risks and regulatory exposure.
4. Review Health Monitoring Programs
Where health monitoring is required, employers should assess whether current arrangements remain appropriate under anticipated exposure requirements.
Regular health monitoring can:
- Detect exposure-related health issues earlier
- Improve treatment and recovery outcomes
- Support compliance obligations
- Reduce the long-term costs associated with occupational illness claims
5. Build Compliance Planning into Current WHS Programs
The transition to WELs should not be viewed as a future problem.
Forward planning now can help organisations avoid costly last-minute changes and compliance pressures.
Practical preparation activities may include:
- Updating risk registers
- Reviewing hazardous chemical inventories
- Refreshing worker training programs
- Budgeting for monitoring and testing services
- Reviewing contractor management processes
- Implementing workplace improvement projects
Why This Matters for Workers Compensation
Unlike many workplace injuries, exposure-related illnesses often develop gradually and may not become apparent until years after the exposure occurred.
When occupational illnesses arise, employers may face:
- Workers compensation claims
- Increased insurance premiums
- Lost productivity
- Workforce shortages
- Regulatory investigations
- Reputational damage
A proactive approach to exposure management not only supports legal compliance but also helps create healthier workplaces, reduce claim costs, and improve long-term business performance.
An Opportunity to Strengthen Workplace Health and Safety
The upcoming transition to Workplace Exposure Limits should be viewed as more than a compliance requirement.
Forward-thinking organisations can use this change as an opportunity to:
- Improve worker health outcomes
- Strengthen workplace safety culture
- Identify outdated work practices
- Reduce long-term injury and illness costs
- Enhance employee wellbeing
- Demonstrate leadership in workplace health and safety
Businesses that act early will be well positioned when the new limits take effect in December 2026.
Need Help Preparing?
Understanding and managing workplace exposure risks can be complex, particularly where hazardous substances, airborne contaminants, workers compensation, and injury management obligations intersect.
