3.2.6.6.(3)

Intent 1:

To limit the probability of excessive delays in locating vent windows in a fire situation, which could lead to delays in the opening of the windows, which could lead to the buildup of smoke on floor areas, which could lead to:

• delays or inefficiencies in fire emergency response operations, which could lead to the spread of fire, which could lead to damage to the building, and
• damage to the building.

Intent 2:

To clarify that windows used for venting are to be of the openable type, on the basis that if fixed windows were permitted, their breakage [by firefighters for venting purposes] could endanger persons below.
