Which material is specifically assessed for its potential friability in schools?

Ceiling tiles are specifically assessed for their potential friability in schools because they can contain asbestos and, when disturbed, can release asbestos fibers into the air. Friable materials are those that can crumble easily and release fibers when dry and damaged. This characteristic is particularly concerning in schools where maintenance or renovation activities may expose these materials to disturbance, thereby posing a health risk to students and staff.

In contrast, while vinyl flooring might also contain asbestos, it is generally considered a non-friable material when intact, as it does not easily crumble. Windows and exterior paint, though they can sometimes be involved in asbestos-related assessments, are not typically at the same level of concern regarding friability as ceiling tiles. Thus, the focus on ceiling tiles reflects their specific risks associated with asbestos exposure in a school environment.
