Intent

Intent 1:

To limit the probability that large closures, which are permitted to have a lower fire resistance than the fire separations in which they are installed, will reduce the fire-resistance rating of the separations, which could lead to the spread of fire from one fire compartment to another, which could lead to harm to persons in the other fire compartment.
