Periodic damage is which of the following?

• A. Periodic damage is a one-time event.
• B. Periodic damage is recurring or continuous.
• C. Episodic damage is ongoing.
• D. Episodic damage is predictable.

Answer: (B)

Periodic damage means the damage pattern repeats over time because the harmful condition recurs or stays present with ongoing exposure. In building inspections, you’d see this when moisture, leaks, or temperature cycles repeatedly affect a spot, so the damage shows up again and again or remains as long as the exposure continues. It isn’t a one-time event, where damage would occur only once. The idea that episodic damage is ongoing isn’t accurate, since episodic implies distinct episodes separated by time rather than a continuous or regular pattern. And saying episodic damage is predictable doesn’t capture the concept of periodic damage, which is defined by repetition or continuity over time.
