Intent
Intent 1: 
To limit the probability that large closures--which are permitted to have a lower resistance to fire than do the fire separations--will reduce the fire-resistance rating of the fire separations, which could lead to the spread of fire from one fire compartment to another fire compartment, which could lead to harm to persons in the other fire compartment.
