Workplace Exposure Standards for Airborne Contaminants are changing across Australia to protect workers from harm. High levels of pollutants like carbon monoxide and particulate matter reduce team performance by up to 5%.
These contaminants impair cognitive functioning in your workforce. Cognitive health is critical for creative and innovative thinking in the modern workplace. Poor indoor air quality also causes long-term health risks, including respiratory and cardiovascular diseases.
WHS ministers decided to change these rules due to health risks. Workplaces must move from Workplace Exposure Standards (WES) to mandatory Workplace Exposure Limits (WEL). This change reflects the legal requirement that these levels must not be exceeded.
All Australian workplaces must transition to the new WEL list by 1 December 2026. This timeline is part of the new WHS compliance requirements for business owners. You must prepare your company for these changes to avoid legal penalties.
Section 19 of the model WHS Act sets a primary duty of care to ensure worker safety. This rule defines what is duty of care in the workplace for every Australian employer. You must eliminate or minimise air risks so far as is reasonably practicable.
You should contact your jurisdictional WHS regulator to understand specific local legal requirements. These local rules apply to small business regulations in Australia.
Read this guide to Workplace Exposure Standards for Airborne Contaminants. Learn how to avoid compliance risks and penalties.
Manage the Risks of Hazardous Airborne Chemicals
Managing chemical risks means identifying airborne hazards and implementing controls to protect worker health. You must follow strict legal frameworks to control dangerous substances in the air. This process protects your team from chronic illness and injury.
Understand Exposure Thresholds and Duty of Care
Workplace exposure limits define the maximum concentration of an airborne contaminant that most people can breathe without harm. These limits do not represent a safe line for workers. Individual differences or existing health conditions can cause adverse effects below the limit.
You must always aim for exposure levels As Low As Reasonably Practicable (ALARP). Workplace Exposure Standards for Airborne Contaminants serve as the baseline for these safety calculations. Keeping exposure below the limit reduces long-term legal risks for your business.
Implement Mandatory Health Monitoring
Health monitoring consists of regular medical tests that track worker health when exposure risks are high. Monitoring health and safety in the workplace are crucial if risks are significant or in the presence of scheduled chemicals. This process must be supervised by a registered doctor to ensure accurate tracking.
The doctor conducts specific medical tests based on the chemical hazard. Identified health effects through monitoring must trigger a review of your current workplace control measures.
Identify Prohibited and Restricted Carcinogens
Prohibited and restricted carcinogens are cancer-causing substances that face strict bans or tight controls under safety regulations. You must check Schedule 10 of the model WHS Regulations to identify these chemicals. Using these substances requires specific written authorisation from the WHS regulator.
Common examples include benzene or acrylonitrile which carry heavy compliance burdens. If you work with these substances you must know what information is on a safety data sheet. And all your suppliers must provide this sheet to your business upon delivery.
Eliminate Non-Threshold Genotoxic Carcinogens (NTGCs)
Non-threshold genotoxic carcinogens are toxic chemicals that damage human DNA and have no safe level of exposure. From December 2026, exposure limits for NTGCs will be completely removed from the law. These chemicals cause permanent genetic damage at any concentration.
Swapping dangerous chemicals protects your workforce from preventable cancers. You must eliminate these substances or replace them with safer alternatives. Then, get ready to update your occupational health and safety policy before the said date.
You can run a chemical safety toolbox talk to educate your workers on these risks. Training helps your team handle chemical changes. It also ensures everyone follows the updated safety guidelines.
Apply Workplace Exposure Limits and Measurement Protocols
Measurement protocols are the scientific testing standards used to evaluate chemical concentrations in the air. These protocols ensure your workplace matches national safety laws. They provide data to verify that your air is safe to breathe.
Workplace Exposure Standards for Airborne Contaminants require precise testing methods. For instance, welding and safety in NSW requires tracking specific metal fumes.
The Workplace Exposure Standard for Welding Fumes was reduced to protect workers. The limit dropped from 5 to 1 mg/m³. This strict limit assists in improving safety practices in construction across the country. Similar air protocols are now used for occupational health and safety in hotels to ensure guest and staff safety.
Categorise the Three Types of Limits
The three types of limits are distinct regulatory timeframes used to calculate worker exposure to airborne hazards. You must measure airborne dusts and fumes in three separate ways under the new list. Each type of limit prevents different forms of health damage.
Employers must understand these categories to stay compliant. Workplace Exposure Standards for Airborne Contaminants are split into these specific time-based controls. Failing to meet any single limit violates safety regulations.
- 8-hour Time Weighted Average (TWA): The maximum average concentration allowed over a standard eight-hour working day.
- Short Term Exposure Limit (STEL): The maximum concentration allowed over a 15-minute period, which must not be exceeded at any time.
- Peak Limitation: A concentration that must never be exceeded, measured over the shortest time possible.
Verify Compliance Through Quantitative Air Monitoring
Quantitative air monitoring is the technical process of measuring exact chemical exposure levels in the workplace air. You must conduct air monitoring if you are uncertain on reasonable grounds whether concentrations exceed the WEL.
Engage a qualified Occupational Hygienist to perform these measurements. These specialists use calibrated pumps and filters to capture air samples. Then, they provide official reports that prove your company complies with the law.
The law requires you to keep these air testing results as a record for 30 years. You must ensure these records are accessible to all exposed workers. This long-term record keeping is mandatory under the Model Work Health and Safety Regulations.
