What is non-friable asbestos-containing material?

Non-friable asbestos-containing material refers to substances that contain more than 1% asbestos but are not easily crumbled or pulverized by hand pressure. This characteristic is crucial because it means that when in good condition, non-friable materials are generally less likely to release asbestos fibers into the air compared to friable materials, which can be easily broken down and pose a higher risk. Examples of non-friable asbestos materials include floor tiles, roofing shingles, and cement products.

The distinction in the percentage of asbestos and the ability to crumble is important for safety and management practices regarding asbestos. Non-friable materials require specific handling and monitoring guidelines to ensure they remain intact and do not become a hazard during renovation or demolition activities. Understanding this classification helps site surveillance technicians implement appropriate protective measures and comply with regulations regarding asbestos safety.
