The Risks and Alternatives of Engineered Stone Bench Tops

Engineered stone bench tops have long been favored for their durability and low maintenance. However, recent research and rising cases of silicosis have raised concerns about the health risks associated with this popular construction material. As a result, the Australian government has decided to ban the use, supply, and manufacture of engineered stone bench tops, making it the first country to take such action. In this article, we will delve into the risks of engineered stone bench tops, explore safe alternatives, and provide guidance for homeowners and builders.

Understanding Engineered Stone Bench Tops

Engineered stone, also known as reconstituted stone or agglomerate stone, is a composite material made by mixing crushed stone with a resin binder. It is manufactured in a factory and can be customized to suit the specifications of any project. Engineered stone bench tops gained popularity due to their durability, resistance to scratches, stains, and heat. However, the cutting and shaping of engineered stone release high levels of silica dust, which has been linked to the development of silicosis.

The Health Risks of Engineered Stone Bench Tops

Silicosis is a serious lung disease caused by the inhalation of silica dust. Silica dust is generated when workers cut, shape, or polish engineered stone. Silicosis can lead to irreversible lung damage and even death. The rising cases of silicosis among stonemasons and other workers exposed to engineered stone dust have prompted health experts and trade unions to advocate for a ban on the material. Australia's decision to ban engineered stone bench tops reflects the urgency to protect workers' health and safety.

The Australian Ban on Engineered Stone Bench Tops

In a world-first move, the Australian government has announced a complete ban on the use, supply, and manufacture of engineered stone bench tops. Most states and territories will implement the ban on 1 July 2024, with the aim of reducing the risks associated with silica dust exposure. The ban applies to all aspects of working with engineered stone, including manufacturing, supplying, processing, and installing. The decision comes as a response to the alarming increase in silicosis cases and serves as a proactive measure to prevent further harm.

Safe Handling of Existing Engineered Stone Bench Tops

Homeowners and builders may be concerned about the engineered stone bench tops already installed in homes. Health experts are divided on whether these slabs should be modified or removed. While some experts assure that the material is safe when left undisturbed, others recommend exercising caution during renovations. Thoracic physician Deborah Yates advises waiting for more data on the risks of lower levels of silica dust exposure before proceeding with modifications. The Lung Foundation's senior manager for occupational lung disease, Elizabeth Early, also suggests a waiting period to minimize the risk of silicosis development.

Safe Alternatives to Engineered Stone Bench Tops

Fortunately, there are several safe and sustainable alternatives to engineered stone bench tops that can be used in construction projects. A platform like Subbix can help builders find these products. These alternatives offer similar durability and aesthetic appeal without the associated health risks. Here are some excellent options to consider:

Natural Stone

Natural stone, such as granite, travertine, onyx, and marble, is sourced directly from the earth. It is long-lasting and naturally beautiful, making it a popular choice for kitchen bench tops.

Terrazzo Slabs

Terrazzo slabs feature a composite of marble, granite, quartz, and glass chips embedded in a cement base. This stylish and durable material offers a distinctive look that can elevate any kitchen or bathroom.

Porcelain Slabs

Porcelain slabs are created using natural materials like clay and minerals, which are fired at high temperatures. The result is a low-porous material that is easy to maintain and offers the same stunning appearance as natural stone.

These alternatives provide homeowners and builders with safe and visually appealing options for their projects, ensuring both aesthetics and health are prioritized.

Precautionary Measures for Working with Engineered Stone Bench Tops

Until the ban on engineered stone bench tops comes into effect, it is essential to take precautionary measures when working with the material. The model WHS Regulations recommend the use of water suppression systems, on-tool dust extraction systems, or local exhaust ventilation systems when cutting, grinding, or drilling engineered stone. Additionally, all workers should be provided with and wear respiratory protective equipment to minimize exposure to silica dust.

The Importance of National Regulations and Licenses

The Australian ban on engineered stone bench tops highlights the need for national regulations and licensing schemes to ensure the safe handling of construction materials containing crystalline silica. The prohibition on engineered stone serves as a wake-up call to prioritize the health and safety of workers and homeowners alike. By implementing strict regulations and licensing requirements, the industry can mitigate the risks associated with silica dust exposure and prevent future cases of silicosis.

Conclusion

The ban on engineered stone bench tops in Australia marks a significant step towards safeguarding the health of workers and homeowners. The risks associated with silica dust and the rise in silicosis cases have prompted the need for safer alternatives in construction projects. Natural stone, terrazzo slabs, and porcelain slabs offer visually stunning options without compromising on durability or aesthetic appeal. While the debate continues on the handling of existing engineered stone bench tops, it is crucial to prioritize the safety of those involved in renovations. Through national regulations and licensing schemes, the industry can ensure the responsible use of construction materials and protect the well-being of all.
