Almost all construction industry workers are regularly exposed to potentially cancer-causing carcinogens, according to the Australian Work Exposures Study: Construction Industry Report published in May 2016.

Using research based on a sample of 459 workers, the report estimated that 96% had a probable exposure to at least one carcinogen while 53% had a probable exposure to four or more carcinogens.

Personal protective equipment (PPE) and the hierarchy of control were identified as playing an important role in minimising the risk of exposure.

For example, a common method of carcinogenic exposure in the construction industry is the inhalation of airborne contaminants for which respiratory protective equipment (RPE), such as dust masks, is an appropriate control method.

However the study found that 46% of carpenters reported not using any RPE despite being the occupation with the highest probable exposure to carcinogenic wood dust.

Carcinogenic Risks

Working with wood, mixing concrete or cement, painting preparation, soldering, welding and refuelling vehicles were identified as the main tasks linked with a high likelihood of exposure.

Separate to workplace tasks, circumstances commonly associated with exposure to carcinogens include working outdoors (UV radiation), working near someone smoking and working near operating diesel-powered vehicles.

Solar UV radiation, environmental tobacco smoke, crystalline silica, diesel engine exhaust and wood dust were the carcinogens which construction workers were most likely to be exposed to, while asbestos, benzene, chromium compounds, formaldehyde, inorganic lead compounds and nickel compounds have also been commonly associated with the construction industry.

Cancers which have been linked to the construction industry include lung cancer, mesothelioma, sinonasal cancer and non-melanoma skin cancer.

While most workers exposed to a carcinogen will not develop cancer, it does increase their risk.

The report found there is a lack of clear information tailored to the construction industry on the exposure and control of carcinogens as well as their health effects.

Where exposure cannot be eliminated, substitution, isolation and engineering controls should be used before administrative approaches and PPE, in accordance with the hierarchy of control, due to their greater effectiveness as control measures.

Nevertheless, PPE remains a critical last line of defence where the other controls are insufficient.

The table below lists preventative measures identified in the study which can minimise the exposure to common carcinogens.

Diesel engine exhaust  

 

Using new generation diesel engines

Maintaining diesel engines, including filter systems

Minimising the time that workers spend near diesel  engines

 

Environmental tobacco smoke  

 

Anti-smoking legislation

Adoption and enforcement of smoking bans

 

Wood dust, and

 

Carcinogenic exposure in welding and soldering tasks

 

 

Local exhaust ventilation

Respiratory protective equipment, including air-supplied helmets and face masks

 

Solar UV radiation  

 

Working in the shade

Clothing that covers arms and legs

Wearing a hat

Sunscreen
