Which term describes insulation that can be easily crumbled by hand?

Explanation:
Friable describes insulation that can be easily crumbled by hand. This term is used to indicate materials that can be reduced to powder or fibers with light pressure, which is especially important in asbestos-related work because friable materials can release respirable fibers simply through handling. The other terms don’t fit the same way: brittle means it can crack or shatter under stress but doesn’t specifically imply easy crumbling by hand; nonfriable means it resists crumbling and generally requires cutting with tools rather than crumbling; solid implies the material isn’t crumbly at all.
