What is ‘friable’ asbestos?
Friable means when dry, or as the result of a work process, may be crumbled, pulverised or reduced to a powder by hand pressure.
What is ‘non-friable’ asbestos?
Non-friable means, when dry may not be crumbled, pulverised or reduced to powder by hand pressure (for example materials containing asbestos that have been mixed with cement or other hard bonding materials).
Non-friable asbestos may become friable
Non-friable asbestos may become friable as a result of work processes over time (for example, degradation due to chemical exposure) or due to other factors (for example, damage by fire).
