What does the term 'friable' mean when describing materials in a school building?

The term 'friable' refers to materials that can be easily crumbled or pulverized by hand pressure. This characteristic is particularly significant in the context of asbestos-containing materials, as friable asbestos poses a greater risk to health. When these materials are disturbed, they can release asbestos fibers into the air, which can be inhaled and lead to serious health issues, including lung disease and cancer.

In school buildings, identifying friable materials is crucial for assessment and management, especially when planning renovations or abatement. Friable materials may require more stringent handling and remediation protocols due to their potential to become airborne and hazardous. Understanding this definition helps in recognizing the risks associated with asbestos and informs proper safety measures in environments such as schools.
