Although both friable and non-friable asbestos present large health risks, friable asbestos is particularly dangerous. According to WorkSafe Australia, if an asbestos-containing material can be crushed into a powder by hand, it’s deemed as friable. The brittle nature of friable asbestos means it is more susceptible to releasing airborne fibres, which represents a greater risk to your health.
A prime example of friable asbestos is asbestos rope, which was used historically to pack around pipes in the walls. Similarly, the notorious “Mr. Fluffy” insulation found in Australia (covered in our last blog) is another example of friable asbestos. However, things can get a little tricky with a substance known as low-density board (LDB). To an untrained observer, LDB, which comes in sheet form, might seem like typical non-friable asbestos. However, due to its high asbestos content, if disturbed, it behaves more like friable asbestos, presenting a higher risk.
On the other hand, non-friable asbestos, also known as bonded asbestos, typically contains about 10 to 15% asbestos by volume. It is often found within a matrix of concrete or vinyl tiles, mixed in for added strength and durability. However, certain non-friable materials, such as bonded asbestos, can become friable under specific conditions. For instance, if you cut bonded asbestos with a grinder or if the asbestos is burnt in a fire, it’s now considered friable.
Many homes contain non-friable asbestos, but a significant number also contain friable asbestos. While the terminology may seem complex, by distinguishing between these two types of asbestos, you can make informed decisions about potential risks in your environment, particularly in the process of renovating or demolitioning your property.
Despite this, the key takeaway from this blog is that any asbestos, whether friable or non-friable, can pose health risks when disturbed. That’s why if you encounter a material in your home you suspect may contain asbestos, don’t risk it – call in the experts. Prevention is always better than cure, and in the case of asbestos, expert handling is crucial. It’s never too late to call in the professionals, but the ideal time is before you begin any renovation or demolition work.
