Nonfriable

Nonfriable refers to a material that does not readily crumble, break apart, or break down into dust when handled or disturbed. The term is often used in relation to asbestos-containing materials. Asbestos is a naturally occurring fibrous mineral that can be dangerous if inhaled in its airborne form. Friable asbestos materials are those that can be easily crumbled by hand, releasing fibers into the air. Examples include spray-applied insulation, damaged asbestos cement, and insulation that has become loose.

Nonfriable asbestos materials, on the other hand, are bound in a matrix, such as cement or vinyl. This binding makes them less likely to release asbestos fibers into the air under normal conditions. Examples of nonfriable asbestos materials include asbestos cement pipes, floor tiles, roofing shingles, and intact asbestos cement siding. While nonfriable materials pose a lower risk than friable materials, they can still become friable if damaged, disturbed, or subjected to wear and tear. For instance, cutting or drilling into nonfriable asbestos cement can release fibers. Therefore, proper handling and abatement procedures are still necessary when dealing with nonfriable asbestos-containing materials to ensure safety and prevent potential health hazards. The distinction between friable and nonfriable is crucial for assessing the risk associated with asbestos and determining appropriate management or removal strategies.
