What are carcinogens

Carcinogens are cancer-causing agents found in various workplace environments. These substances can increase your risk of developing certain types of cancer through prolonged exposure. Common workplace carcinogens include:

  • Combustion products (diesel engine exhaust, second-hand smoke)
  • Inorganic dusts (asbestos, silica dust)
  • Organic dusts (leather dust, wood dust)
  • Metals (arsenic compounds, nickel compounds)
  • Radiation (UV radiation from artificial sources and the sun)
  • Industrial chemicals (benzene, aromatic amine dyes)
  • Entire occupations and industries (firefighting, painting, and aluminium production)

Workplace dangers

Understanding workplace dangers is essential so you can protect yourself and your colleagues. The International Agency for Research on Cancer has identified 198 known and probable cancer-causing agents, with many present in workplaces.

Here are some important facts to know about occupational hazard risks:

  • Over 5,000 new cancer cases in Australia each year are linked to workplace exposure.
  • 38 high-priority carcinogens are specific to Australian workplaces.
  • All employers must manage known risks using the Hierarchy of Control.
  • Employees have the right to speak up about health and safety concerns.

Environmental hazards in the workplace

Environmental hazards in the workplace can vary depending on your industry and location. Here are key hazards to watch:

  • Asbestos
  • Welding fumes
  • Environmental tobacco smoke
  • Diesel engine exhaust
  • UV radiation
  • Silica dust
  • Wood products

Asbestos

Asbestos can pose serious health risks if disturbed. Even though it was banned in Australia in 2003, asbestos is still present in many older materials and buildings. Understanding where asbestos is found, how it can affect your health, and what steps you can take to stay safe is essential.

Asbestos is a natural mineral made of tiny, fibrous particles that can cause harm if inhaled.

Learn more about asbestos.

Where it can be found:

  • Roofing, flat and corrugated sheeting
  • Cement pipes and insulation
  • Floor tiles and adhesives
  • Textiles and textured paints
  • Brake pads and vehicle parts

In some areas, asbestos also occurs naturally in soil and rock. This is most common in road building, construction, excavation, and mining.

Taking action against asbestos

Workplaces should follow Workplace Health and Safety Queensland’s codes of practice:

When working in areas where asbestos may exist in its natural state, workplaces can refer to Geological Survey of Queensland to check geological survey information.

No matter your workplace, taking proactive steps to stay safe is crucial. Visit our Taking action to stay safe section for general health and safety guidelines that apply to all hazards.

What to do if you’ve been exposed to asbestos

If you think you’ve been exposed to asbestos, take action:

  • Talk to your doctor: Let your doctor know about any possible asbestos exposure, especially if you work in a high-risk industry.
  • Monitor your health: Stay aware of any changes in your health and seek medical advice if needed.
  • Register your exposure: The National Asbestos Exposure Register keeps a record of potential exposures.

Questions you may have…

Who is at risk?

People most likely to be exposed to asbestos include:

  • Builders, plumbers, and electricians
  • Mechanics and transport workers
  • Asbestos miners and cement manufacturers
  • DIY renovators working on older homes

If you work with materials installed before January 2004, you may be at risk of asbestos exposure.

How can asbestos affect your health?

Asbestos fibres are so small that they can’t be seen, but they can easily be inhaled. Once in the lungs, these fibres can become trapped and cause damage over time.

  • Asbestos fibres are 50–200 times thinner than a human hair, making them nearly invisible.
  • Fibres are often released during unsafe handling of asbestos-containing materials, such as during renovations or demolition.

These tiny fibres can lead to serious health problems, often many years after exposure.

What cancers are linked to asbestos?

Asbestos exposure can increase the risk of developing:

  • Lung cancer
  • Ovarian cancer
  • Laryngeal cancer (voice box)
  • Mesothelioma (a cancer of the lining of the lungs)

These conditions often take decades to develop, which is why early prevention and action are crucial.

Welding fumes

Welding is the process of permanently joining two or more materials, usually metals, using heat, pressure, or both. Welding fumes can pose serious health risks when inhaled, as they contain harmful gases and fine particles. Ultraviolet (UV) radiation in the welding arc is also a hazard. Understanding the dangers of exposure and taking steps to minimise risk is essential for staying safe at work.

Welding fumes are created when metal is heated to a high temperature and then cools down. As it cools, it turns into fine particles and fumes that can be inhaled. These fumes contain substances that can potentially cause cancer, such as metallic oxides, silicates, and fluorides. There are many different welding techniques, but most fall into the categories of electric arc welding or oxy-fuel welding.

Taking action to stay safe

Workplaces should follow Workplace Health and Safety Queensland’s codes of practice:

Airborne Contaminants Exposure Limits also details how employers and workers can control welding hazards to minimise exposure to contaminants in the air.

The Fume Minimisation Guidelines from Weld Australia also contain further information about controlling airborne contaminants.

No matter your workplace, taking proactive steps to stay safe is crucial. Visit our Taking action to stay safe section for general health and safety guidelines that apply to all hazards.

What to do if you’ve been exposed to welding fumes

If you think you’ve been exposed to welding fumes, it’s important to:

  • Talk to your doctor: Inform them of any exposure to welding fumes or UV radiation.
  • Monitor your health: Pay attention to any respiratory issues or changes in health and seek medical advice.

Learn more about how to manage welding risks at work with the Queensland Government

Questions you may have…

Where can welding be found?

Welding fumes are present wherever welding is taking place, such as in:

  • Construction sites
  • Manufacturing plants
  • Automotive repair workshops
  • Shipbuilding and metal fabrication
Who is at risk?

People who work directly with welding activities or are in close proximity to them, including:

  • Welders
  • Boilermakers
  • Fabricators
  • Construction workers
  • People working in enclosed or confined spaces
How can welding fumes affect your health?

Welding fumes contain a range of toxic chemicals that can cause serious health issues. Prolonged exposure can lead to respiratory problems, lung damage, and increase the risk of cancer and other serious lung conditions.

  • Welding fumes are classified as a Group 1 carcinogen (meaning they are proven to cause cancer in humans).
  • Exposure to welding fumes, especially in poorly ventilated areas, can cause serious lung conditions, including lung cancer.
What cancers are linked to welding fumes?

Welding fumes and ultraviolet (UV) radiation from the welding arc are linked to an increased risk of developing:

  • Lung cancer
  • Eye melanoma
  • Other cancers

Environmental tobacco smoke

Environmental tobacco smoke, or second-hand smoke, is a harmful mix of smoke from the tip of burning cigarettes and smoke exhaled by smokers, containing thousands of toxic chemicals, including many that cause cancer. This page also covers third-hand smoke, which refers to toxic residues left on surfaces, and environmental e-cigarette emissions.

Environmental tobacco smoke, also called second-hand smoke, is a mixture of:

  • Side-stream smoke: smoke released from the tip of a burning cigarette
  • Mainstream smoke: smoke exhaled by the smoker

Second-hand smoke is a carcinogen, containing around 7,000 chemicals, including 69 that can cause cancer. There is no safe level of exposure to second-hand smoke. Even low levels, including outdoor exposure, can be harmful.

Third hand smoke

Third-hand smoke refers to the toxic residues left on surfaces and in dust after tobacco has been smoked. In workplaces, these residues can linger on furniture, walls, and equipment, potentially exposing employees long after smoking has occurred. People who spend some time in contaminated spaces may face increased risks of toxin exposure through skin contact, inhalation, or ingestion.

To reduce these risks, workplaces should enforce comprehensive no-smoking policies, including prohibiting smoking in outdoor areas near building entry points, and ensure regular cleaning and ventilation. However, it’s important to note that cleaning alone may not completely eliminate third-hand smoke residues. Employers should stay informed about ongoing research and take proactive steps to protect workers.

Environmental e-cigarette emissions

Similar to tobacco smoke, second-hand and third-hand exposure to e-cigarette emissions should be avoided. Research on the effects of environmental e-cigarette emissions is still limited, but studies show that harmful chemicals can be inhaled by those nearby. E-cigarettes can emit chemicals like nicotine and cancer-causing substances like formaldehyde. To protect your health, avoid exposure to e-cigarette emissions, just as you would with tobacco smoke.

Benefits of a smoke-free workplace

A smoke-free workplace benefits both employers and employees by

  • Improving employee health
  • Boosting productivity (fewer smoking breaks)
  • Reducing sick leave and early retirements
  • Lowering cleaning, maintenance, and fire risks
  • Enhancing the business’s healthy image
  • Supporting smokers to cut down or quit
  • Discouraging smoking uptake among younger workers

Taking action to stay safe

To reduce the risks of second-hand smoke exposure in the workplace, employers should refer to Safe Work Australia’s Guidance note on the elimination on environmental tobacco smoke in the workplace and:

  • Ban smoking in the workplace
  • Develop a written no-smoking policy
  • Provide smoking cessation support
  • Establish designated smoking areas
  • Use signage

No matter your workplace, taking proactive steps to stay safe is crucial. Visit our Taking action to stay safe section for general health and safety guidelines that apply to all hazards.

What to do if you’ve been exposed to environmental tobacco smoke

If you think you’ve been exposed to prolonged environmental tobacco smoke:

  • Talk to your doctor
  • Stay aware of any changes in your health and seek medical advice if needed.

No matter your workplace, taking proactive steps to stay safe is crucial. Visit our Taking action to stay safe section for general health and safety guidelines that apply to all hazards.

Questions you may have…

How does environmental tobacco smoke affect health?

Second-hand smoke contains more toxins than the smoke directly inhaled by the smoker. This is due to side-stream smoke being produced at lower temperatures and without a filter, which results in higher concentrations of harmful chemicals. Additionally, smaller particles in side-stream smoke can penetrate deeper into the lungs, increasing its toxicity.

  • Old side-stream smoke: can be up to 12 times more toxic than the smoke inhaled by the smoker.
  • Long-lasting toxins: up to half of the chemicals from second-hand smoke can remain in the air for 5-6 hours.

Non-smokers exposed to second-hand smoke face:

  • 25-30% higher risk of heart disease
  • 20-30% higher risk of lung cancer
Which cancers is environmental tobacco smoke linked to?

Exposure to second-hand smoke is linked to the development of several types of cancer, including:

  • Lung cancer
  • Nasal sinus cancer
  • Breast cancer (possible link)

The cancer risk from second-hand smoke depends on several factors, including the duration of exposure, toxicity levels, ventilation, and the size of the space. Second-hand smoke is harmful to everyone, with non-smokers being particularly sensitive.

Diesel engine exhaust

The cancer risk from second-hand smoke depends on several factors, including the duration of exposure, toxicity levels, ventilation, and the size of the space. Second-hand smoke is harmful to everyone, with non-smokers being particularly sensitive.

The Australian Institute of Occupational Hygienist’s Diesel Particulate Matter and Occupational Health Issues Position Paper recommends workplace exposure limits that help to reduce the irritant effect of DEE. However, the limit in this paper is higher than the level of DEE which is associated with cancer.

No matter your workplace, taking proactive steps to stay safe is crucial. Visit our Taking action to stay safe section for general health and safety guidelines that apply to all hazards.

What to do if you’ve been exposed to diesel engine exhaust

  • Talk to your doctor.
  • Stay aware of any changes in your health and seek medical advice if needed.

Questions you may have…

Who is at risk?

There is a risk of exposure to DEE for anyone working with or around diesel-powered engines, especially in confined spaces. Workers in mining, construction, agriculture, transport, and vehicle maintenance are most likely to be exposed.

Which cancers is diesel engine resource linked to?

DEE is classified as a Group 1 carcinogen (meaning it is proven to cause cancer in humans). Chemicals in DEE can cause many short- and long-term health problems.

Regular exposure to high levels of DEE, over a long period of time, increases the risk of getting lung and potentially bladder cancer.

UV radiation

Ultraviolet (UV) radiation is a type of invisible energy produced by the sun and some artificial sources, such as welding arcs. UVA and UVB rays from the sun reach the earth’s surface and are classified as carcinogenic to humans. Overexposure to UV radiation can harm skin cells and contribute to increased skin cancer risk.

Taking action to stay safe

While sun protection is important for everyone when UV levels reach 3 or higher, outdoor workers need protection at all UV levels, even 1 and 2. This is because they receive significantly more UV exposure throughout their lives, putting them at increased risk of skin cancer.

Stay safe while driving

Car windows don’t block all UV radiation. Most skin damage in vehicles comes from passenger and open windows. To minimise risk, wind up windows and use air conditioning. If you spend a lot of time in vehicles, combine sun protection (long-sleeved shirts, sunglasses, sunscreen) to protect yourselves inside and outside the vehicle. No matter your workplace, taking proactive steps to stay safe is crucial. Visit our Taking action to stay safe section for general health and safety guidelines that apply to all hazards.

What to do to find skin cancer early

Develop a regular habit of checking your skin for any new or changes to existing moles, freckles or lumps. Speak to your health professional:

  • If you notice any new or changes (in size, shape or colour) to existing moles, freckles, or bumps.
  • If you have a mole, freckle or bump that doesn’t heal within 4-6 weeks.

On top of checking your own skin, you should get your skin checked regularly by a health professional. This can be your GP or a dermatologist (skin disease doctor). Discuss with your health professional what regular looks like for you.

Stay aware of any changes in your health and seek medical advice if needed.

Questions you may have…

Who is at risk

Over 1.2 million Australian workers are exposed to solar UV radiation at levels five to 10 times more than indoor workers. Solar UV radiation at work contributes to about 200 melanomas and 34,000 non-melanoma skin cancers each year in Australia. UV radiation can damage all skin types, and this damage adds up over time. While skin cancer can affect anyone, outdoor workers are at a significantly higher risk of developing it due to increased UV exposure.

How does UV radiation affect my health?

UV radiation has been linked to skin cancer and cancer of the eye. It can also contribute to cataracts (clouding on the lens of the eye) and pterygium (a growth on the white of the eye).

Silica dust

Silica dust (crystalline silica) is found in stone, rock, sand, gravel, clay, and materials like bricks, tiles, concrete, and some plastics. The most common form is quartz. When these materials are worked on, silica dust is released, which can be harmful when inhaled.

Taking action to stay safe

No matter your workplace, taking proactive steps to stay safe is crucial. Visit our Taking action to stay safe section for general health and safety guidelines that apply to all hazards.

What to do if you’ve been exposed to silica dust

If you’re concerned about your health due to silica dust exposure, talk to your doctor. Be aware of any health changes and seek medical advice if needed.

Questions you may have…

Who is at risk?

In 2011, about 587,000 Australian workers were exposed to silica dust. It is estimated that 5,758 of these workers will develop lung cancer from their exposure over their lifetime. Occupations at high risk include:

  • Miners
  • Construction workers
  • Farmers
  • Engineers

You may be exposed if your work involves tasks like:

  • Breaking, crushing, or grinding materials containing silica
  • Sandblasting or casting
  • Paving, cement finishing, or bricklaying
  • Demolition work
  • Road construction or stonemasonry
  • Mineral ore treatment
  • Manufacturing glass, ceramics, concrete, tiles, or machinery
How can silica dust affect my health?

Silica dust is harmful when inhaled. It’s fine enough (100 times smaller than a grain of sand) that you may not even notice it. Long-term or repeated high-level exposure can cause:

  • Lung cancer
  • Silicosis (irreversible lung damage)
  • Kidney disease
  • Chronic obstructive pulmonary disease (COPD)

Approximately 230 people develop lung cancer each year due to past exposure to silica dust at work. While not all exposed workers will develop cancer, the risk increases with prolonged exposure.

Wood products

Wood dust is created during woodworking activities like cutting, sanding, and machine operations. It can also be released when disturbing settled dust, such as during cleaning or maintenance.

Taking action to stay safe

  • Follow the relevant code of practice: workplaces should follow Workplace Health and Safety Queensland’s Abrasive blasting Code of Practice 2021 and Demolition work Code of Practice 2021.
  • Air monitoring: workplaces must conduct air monitoring if you’re unsure whether airborne substance levels exceed the exposure standard or if monitoring is needed to assess health risks.
  • Health monitoring: workplaces must ensure health monitoring for workers handling hazardous chemicals if there is a significant risk to their health due to exposure.
  • Prevent exposure: keep wood dust and formaldehyde out of the air through proper ventilation and dust control measures.

No matter your workplace, taking proactive steps to stay safe is crucial. Visit our Taking action to stay safe section for general health and safety guidelines that apply to all hazards.

What to do if you’ve been exposed to wood products

If you’re concerned about exposure, talk to your doctor and stay aware of any health changes. Seek medical advice if needed.

Questions you may have…

Which cancers is wood dust linked to?

Wood dust and formaldehyde, both released during woodworking, are classified as Group 1 carcinogens by the International Agency for Research on Cancer (IARC). Prolonged exposure to these can cause cancers of the nasal cavity, sinuses, and nasopharynx, as well as leukaemia.

Where can formaldehyde be found?

Formaldehyde is a strong-smelling gas used in glues for pressed wood products like plywood, particleboard, and MDF. It is released as a vapour and can attach to dust particles in the air.

Who is at risk?

In 2010, 14% of Australian workers were exposed to wood dust and related fumes, with the highest exposure among:

  • Woodworking machine operators
  • Cabinet makers
  • Furniture finishers
  • Carpenters
  • Workers in wood product manufacturing

You may be at risk if your work involves cutting, sawing, sanding, routing, or milling wood or pressed wood products.

Presumptive legislation for firefighters

Under the Workers’ Compensation and Rehabilitation Act 2003, firefighters diagnosed with one of 23 specified cancers or diseases are presumed to have developed their condition as a result of their work, as long as they meet the required qualifying period of service. This means that firefighters do not need to prove that their cancer or disease was work-related in order to file a workers’ compensation claim.

This provision applies to all current and former firefighters, including full-time, auxiliary, and volunteer staff, who are diagnosed with one of the listed cancers or diseases after serving the prescribed period.

While this legislation helps simplify the process of claiming workers’ compensation for cancer-related conditions, it does not replace the need for ongoing prevention and safety measures in the workplace. Firefighters, like all workers, should continue to follow safety protocols to reduce exposure to risk factors and prevent cancer wherever possible.

Taking action to stay safe

To protect yourself from workplace dangers and maintain a safe working environment, always follow your workplace safety procedures and make proper use of any protective equipment provided. It’s also essential to be proactive in reporting potential environmental hazards in the workplace as soon as you identify them. Stay informed about occupational hazard risks through regular updates and make the most of any workplace safety training opportunities you have.

Workplaces:

  • Are required to comply with health and safety laws under Queensland’s Work Health and Safety Act 2011 as part of their duty of care.
  • Should eliminate or reduce exposure to hazards using the hierarchy of control and put a risk management process in place.
  • Are required to train workers on hazards and the policies and procedures to manage them as a work health and safety requirement.

Workers:

  • Must take care of their own health and safety.
  • Must not negatively affect the health and safety of other people.
  • Must follow any reasonable instruction and workplace health and safety policies.
  • Should always be involved in the risk management process to correctly identify hazards and use control measures that suit the workplace.
  • Should make the most of any workplace safety training opportunities available.

Questions you may have…

What are carcinogens and how can I identify them in my workplace?

Carcinogens are substances that can cause cancer, and they can include materials like asbestos, wood dust, and certain chemicals. In Queensland, workplaces are required to manage these risks under the Work Health and Safety (WHS) Act. This includes maintaining a hazardous substances register and providing Safety Data Sheets (SDS) for workers to identify and understand the risks associated with carcinogens. Employers must ensure that exposure to these substances is controlled and does not exceed safe limits. Additionally, workers should be provided with appropriate training, personal protective equipment, and guidance on handling hazardous substances safely. For more information on identifying and managing carcinogens in your workplace, you can refer to resources from WorkSafe Queensland or consult the WHS regulations.

How do I report workplace dangers if I notice them?

If you notice a workplace danger, you should first report it to your immediate supervisor or health and safety representative. If the issue isn’t addressed, or if it’s a serious safety concern, you can contact Workplace Health and Safety Queensland (WHSQ) at 1300 362 128. For certain incidents, such as fatalities or serious injuries, you are legally required to notify WHSQ immediately. You can do this either by calling the number or through their online incident notification form. For non-notifiable incidents, while not mandatory, WHSQ recommends documenting and investigating them to prevent recurrence. This helps in identifying safety improvements to avoid future risks.

How can I protect myself from environmental hazards in the workplace while working outdoors?

To protect yourself from environmental hazards while working outdoors, it’s essential to follow your workplace’s health and safety policies. This includes using any protective equipment provided, such as sunscreen, hats, sunglasses, and protective clothing. You should also make use of shade structures whenever possible to limit your exposure to harmful UV radiation.

Outdoor workers are at a higher risk of skin cancer due to prolonged exposure to UV radiation. Employers must take steps to minimise these risks, such as implementing sun protection measures and conducting regular risk assessments. Outdoor workers should be sun safe at all UV levels.

Additionally, be mindful of other environmental risks in your workplace, such as air quality alerts, and always stay informed about potential hazards through workplace danger alerts. Regularly checking these updates and following guidelines can help you stay safe on the job.
