9.3.3.2.(2)

Intent 1:

To limit the probability that sheet steel exposed to continual wetting will corrode, which could lead to premature failure.

This is to limit the probability of compromised structural integrity, which could lead to:

• structural failure, or
• where sheet steel is used in an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

This is to limit the probability of harm to persons.
