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 harm to persons, including emergency responders, and
• delays in evacuation or moving to a safe place, which could lead to harm to persons.

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.
