Why now is the time to re-evaluate respiratory protection.
For many Australian businesses, respiratory protection programs have remained largely unchanged for years. Workers are issued respirators, fit testing is completed, and daily tasks continue as usual. Where respiratory protection is required, it remains an important part of workplace control strategies, particularly when used alongside higher-order controls to help reduce worker exposure to airborne hazards.
A critical part of any respiratory protection program is selecting the right respirator and filter for the task. The selected respiratory protection must help reduce worker exposure to below the applicable exposure limit for the airborne contaminant present.
On 1 December 2026, Australia will formally transition from Workplace Exposure Standards (WES) to Workplace Exposure Limits (WEL).
While this change may appear administrative, it may have practical implications for respiratory protection selection and workplace respiratory protection programs across construction, manufacturing, and industrial environments.
In many cases, the work being performed may not have changed.
This makes it an important time for businesses to review their exposure assessments, existing controls, respirator selection processes, and overall respiratory protection programs.
A Change That Could Impact Existing Respiratory Protection
Exposure limits are designed to help protect workers from the health effects of airborne contaminants such as respirable crystalline silica, welding fumes, metal dusts, vapours, mists and other hazardous substances commonly encountered across construction, manufacturing and industrial workplaces.
As exposure limits are reviewed and updated, some businesses may find that respiratory protection previously considered adequate no longer provides the level of protection required under the new limits.
This does not automatically mean workers need different equipment. However, it does mean many organisations should review their respiratory protection programs and reassess whether current controls remain appropriate.
Looking Beyond the Respirator
One of the most common misconceptions is that respiratory protection is simply about selecting a filter and a facepiece. In reality, respirator selection is only one part of an effective respiratory protection program. The process should also consider:
- The airborne contaminant and exposure level
- The work activity being performed
- Task duration
- Environmental conditions
- Facial fit and compatibility with other PPE
- Worker comfort and acceptance
- Maintenance, cleaning and storage requirements
A respirator can only provide its intended level of protection when all these factors are considered together.
Why Re-Evaluation Matters
A respiratory protection review is often triggered by a workplace change such as a new process, new materials or a newly identified hazard.
The transition from WES to WEL creates another important reason to review existing programs.
For example, workplaces involved in concrete cutting, grinding, demolition, fabrication, welding or manufacturing may already have respiratory controls in place. However, if exposure limits have changed, businesses should consider whether the selected respirator still provides the necessary protection factor for the application.
This is particularly important where exposure levels are close to regulatory limits or where workers are exposed to airborne contaminants for extended periods.
Worker Comfort Is Becoming Increasingly Important
As businesses review respiratory protection, comfort and wearability are becoming key considerations.
Workers are often required to wear respiratory protection for longer periods and in challenging environments. Equipment that is uncomfortable, interferes with communication, or creates excessive breathing resistance can impact compliance and productivity.
As a result, many organisations are taking a broader look at available respiratory protection options, including reusable respirators, powered air respirators and integrated systems that can help improve wearer comfort while maintaining protection.
The best solution will always depend on the specific application, hazard and workplace environment.
Expert Assessment Can Simplify the Process
For businesses already managing multiple safety obligations, understanding how regulatory changes impact respiratory protection can seem complex. The good news is that organisations do not have to navigate the process alone.
Respiratory protection specialists can assist with protection factor evaluation, respirator selection, fit testing guidance and broader program considerations, helping businesses understand whether existing arrangements remain suitable under the changing exposure landscape.
Preparing for the Future
The move from WES to WEL is ultimately about improving worker health outcomes. For employers, now is an ideal time to review existing respiratory protection programs, confirm that current solutions remain appropriate and identify opportunities to strengthen worker protection where required.
Sometimes the review confirms existing controls are working well. In other cases, it may highlight opportunities for improved fit testing, enhanced training, upgraded respiratory protection or alternative solutions better suited to the task.
The important step is starting the conversation before changes take effect. Respiratory protection is not a one-off decision. As workplace risks and exposure limits evolve, regular re-evaluation helps ensure workers remain protected both today and into the future.
