Lead is a highly toxic metal that poses serious health risks when inhaled or ingested, especially in workplaces involving welding, paint removal, battery handling or demolition of older buildings.
Exposure can result in conditions such as obstructive lung disease, kidney and central nervous system damage, neurological disorders, reproductive harm, anaemia, and in severe cases, fatal poisoning.
Children are particularly vulnerable, especially when exposed to lead-contaminated dust or soil from deteriorating paint. Adults are also at risk, particularly during renovation or demolition activities where lead dust is generated.
Lead testing is typically triggered during refurbishment, demolition or maintenance of older buildings where lead-based materials may be present, especially where work may disturb painted surfaces, dust or contaminated soils and create a risk of exposure.
If lead is not identified early, it can affect how works are carried out, including the need for additional controls, revised methodologies or specialist remediation. This can lead to delays, increased costs and changes to project scope.

In Australia, lead exposure is regulated under the Work Health and Safety Regulations 2011, which require employers and persons conducting business or undertaking (PCBUs) to identify and assess any work involving lead processes.
If a task is classified as lead risk work, the employer must:
These requirements apply across all states and territories under harmonised Work Health and Safety (WHS) laws.
Lead testing typically involves targeted sampling of materials such as painted surfaces, dust or soil based on how the site will be used or disturbed. The scope is designed to identify potential exposure pathways and provide data that supports planning, risk control and safe work practices.
Lead risks are more commonly associated with older assets, industrial sites and locations with historical use of lead-based products. Testing is often required where works may disturb coatings, surfaces or soils that could contain lead.
If lead is detected, control measures may be required to manage the risk. This can include containment, removal, cleaning or changes to how work is carried out to prevent exposure.
Responsibility typically sits with the party managing the workplace or project. They are required to identify hazards and ensure risks are controlled to protect workers and others on site.
