What is the definition of friable material in the context of asbestos?

In the context of asbestos, friable material is defined as material that can be easily crumbled, pulverized, or reduced to powder using hand pressure. This definition is critical because friable asbestos poses a greater risk to health compared to non-friable materials. When friable asbestos is disturbed, it can release airborne fibers that can be inhaled, leading to serious health issues such as asbestosis, lung cancer, and mesothelioma.

Understanding the characteristics of friable materials is vital for asbestos inspectors and health risk assessors so they can appropriately identify, manage, and mitigate the risks associated with asbestos exposure in buildings and other structures. This definition is a foundational concept in asbestos training, highlighting the importance of proper handling and remediation planning for friable asbestos materials.
