Increase in asbestos related cancer among DIY home renovators
A ‘third wave’ of asbestos-related cancer has emerged among home renovators
, according to latest research at The University of Western Australia’s School of Population Health.
The study published in the September issue of the Medical Journal of Australia has found a sharp increase in the number of malignant mesothelioma cases in Western Australia over the past decade as a result of home renovation/do-it-yourself (DIY) activities involving building products containing asbestos.
The domestic exposures are being described as part of the ‘third wave’ of asbestos-related diseases, the first being in miners, millers and transport workers, and the second in workers who used asbestos products.
Although occupational exposures remain the main cause of mesothelioma, in the last five years home renovation/DIY exposures accounted for about 13% of all cases.
Home renovation activities that lead to asbestos exposure included construction using asbestos cement sheets, particularly if sawing or drilling the sheets, and the removal or demolition of these sheets. In some cases, bystanders were also exposed.
Lead author Nola Olsen said while the exposures occurred before asbestos-containing products were banned there is still a concern due to the large number of homes and buildings that still contain these products.
“Asbestos-containing products such as asbestos cement sheets are still found in many homes, particularly older homes and fences. A recent survey by our colleagues at Curtin University found that many people did not take adequate precaution when dealing with these products. They also found that people, even tradespeople, do not think they can easily identify asbestos-containing products. Our study shows that exposures in the home, at a time when people were less aware of the health issues and these asbestos products were still legally available, have unfortunately had dire consequences for some,” Ms Olsen said.
Due to the widespread distribution of asbestos-containing products in Australian homes and the amount of home renovation/DIY work that has happened in the past, the researchers believe it is likely that the number of mesothelioma cases attributed to these exposures will increase.
