damage is a one-time occurrence, a freak event unlikely to recur. For example, episodic
damage results from a pipe or valve bursting, or a plumber disregarding safe work
practices, etc.

What is potential damage by AHERA ? - ANSWER - Friable ACBM in an area regularly
used by building occupants, including maintenance personnel in the course of their
normal activities; there are indications that the material will become damaged,
delaminated or deteriorated.
