[F82-OS1.2]Applies to portion of Code text: “A tightly fitted access door shall be installed for each fire damper to provide access for the inspection of the damper …”


Intent 1:

To limit the probability that fire dampers will not be properly maintained, which could lead to their failure to close in fire conditions, which could lead to the spread of fire from one fire compartment to another fire compartment through openings in the fire separation between the fire compartments, which could lead to harm to persons in the other fire compartment.
