Employees Health provides lead health monitoring programs for employers managing workers who may be exposed to lead or undertaking lead risk work.
Programs can be coordinated nationally and delivered onsite where appropriate, supported by doctors, nurses and allied health professionals experienced in occupational health and workplace monitoring.
Lead health monitoring may include worker history, exposure information, blood lead testing, clinical review and reporting to support workplace health management and WHS processes.
Whether your workforce operates from a single site or across multiple locations, Employees Health can help coordinate lead health monitoring programs that align with workplace exposure risks and operational requirements.
Lead health monitoring may be required when workers are exposed to lead or lead-containing materials as part of their work activities.
Industries and workplaces commonly requiring lead monitoring may include:
Health monitoring requirements should be determined through workplace risk assessment and consideration of applicable WHS obligations.
Before commencing work in an inorganic lead process, it’s crucial to gather comprehensive information regarding the worker’s medical history, including reproductive, neuropsychological, hematological, and renal aspects. Additionally, details about prior non-work-related lead exposure, medication history, and smoking habits are recorded.
A thorough physical examination, focusing on various systems such as gastrointestinal, hematopoietic, renal, cardiovascular, reproductive, and neurological, may be necessary, especially when respiratory protective equipment is required.
Biological monitoring involves regular assessments of blood lead levels, full blood examination, serum creatinine, routine urinalysis, and pulmonary function testing if exposure occurs via airborne lead fumes or dust.
Baseline health monitoring is mandatory before a worker starts lead risk work, with blood lead levels repeated one month after commencing the work. If lead risk work is identified after the worker starts, health monitoring must be initiated promptly, with subsequent blood lead level checks.
Baseline health monitoring is mandatory before a worker starts lead risk work, with blood lead levels repeated one month after commencing the work. If lead risk work is identified after the worker starts, health monitoring must be initiated promptly, with subsequent blood lead level checks.
Regular blood lead level testing is scheduled based on specific criteria, with increased frequency if the nature or duration of lead exposure changes significantly.
Workers exhibiting adverse symptoms or surpassing specified blood lead levels must be promptly removed from lead risk work until their levels decrease to safe thresholds. Pregnant or breastfeeding workers may have additional requirements for removal.
Return to Work and Final Medical Examination
Workers are permitted to return to lead risk work only after meeting established criteria and undergoing medical clearance. A final medical examination assesses any lingering health effects from lead exposure.
Potential Health Effects and Carcinogenicity
Inorganic lead exposure can lead to various health issues, including neurological, hematological, cardiovascular, and reproductive effects. Certain lead compounds are classified as carcinogens, necessitating careful handling and monitoring.
Blood lead monitoring under the WHS Regulations
| Stage | Males, and females not of reproductive capacity | Females of reproductive capacity |
| 1. Starting lead risk work | ||
| Before starting | Medical examination and baseline blood lead test | Medical examination and baseline blood lead test |
| 1 month after starting | Blood lead test | Blood lead test |
| 2. Ongoing blood lead testing (interval set by the last result) | ||
| Every 6 months | Below 10 µg/dL (0.48 µmol/L) | Not applicable |
| Every 3 months | 10 to below 20 µg/dL (0.48 to 0.97 µmol/L) | Below 5 µg/dL (0.24 µmol/L) |
| Every 6 weeks | 20 µg/dL (0.97 µmol/L) or more | 5 to below 10 µg/dL (0.24 to 0.48 µmol/L) |
| 3. Removal from lead risk work | ||
| Remove immediately | 30 µg/dL (1.44 µmol/L) or more | 10 µg/dL (0.48 µmol/L) or more |
| After removal | A second medical examination within 7 days, and review of lead controls | A second medical examination within 7 days, and review of lead controls |
| 4. Return to lead risk work | ||
| Return allowed when | Blood lead is below 20 µg/dL (0.97 µmol/L) and the supervising doctor confirms the worker is fit to return | Blood lead is below 5 µg/dL (0.24 µmol/L) and the supervising doctor confirms the worker is fit to return |
A worker must also be removed if the supervising doctor recommends it, or if a control measure has failed and blood lead levels are likely to reach the removal level. Workers who are pregnant or breastfeeding should be offered alternative duties that do not involve lead exposure, and in some jurisdictions, such as Western Australia, removal is mandatory. Based on Safe Work Australia’s health monitoring guide for lead and Part 7.2 of the model WHS Regulations. Check your state or territory regulator, as requirements can vary.
If your organisation requires lead health monitoring, blood lead testing, occupational health assessments or workforce monitoring programs, Employees Health can help coordinate a solution suited to your workforce and operational requirements.

Once exposure stops, blood lead levels can fall over time, but lead stored in the bones can remain for many years and be released slowly. Removing the source of exposure is the first step. For very high levels, specialist treatment such as chelation may be considered by a doctor.
Headaches are one of the possible symptoms of raised lead levels, along with fatigue, abdominal pain, constipation and tingling. These symptoms are non-specific and have many other causes, and people with raised levels may have no symptoms at all, so a blood lead test is the reliable way to check exposure.
Lead risk work is work in a lead process that is likely to raise a worker’s blood lead level above 20 µg/dL, or above 5 µg/dL for females of reproductive capacity. It can include battery manufacture and recycling, lead smelting, removing lead paint, and some soldering, casting and demolition work.
Health monitoring is required before a worker starts lead risk work and 1 month after. After that, the frequency depends on results: for males and females not of reproductive capacity, it is 6-monthly below 10 µg/dL, 3-monthly from 10 to under 20 µg/dL, and every 6 weeks at 20 µg/dL or more. Females of reproductive capacity are tested more often.
A worker must be removed immediately if their blood lead level reaches 30 µg/dL (or 10 µg/dL for females of reproductive capacity), if the supervising doctor recommends it, or if a control has failed and levels are likely to reach these limits. The employer must notify the regulator and arrange a medical examination within 7 days.
Yes. Employees Health can provide blood lead testing, medical review and reporting onsite at your workplace, anywhere in Australia, and track results against the testing intervals in the WHS Regulations.
