| Intent | Intent 1: To limit the probability of excessive glazing in certain
doors and sidelights, which could lead to radiation exposure and excessively
high temperatures in the area near the unexposed side of the door or sidelight
during a fire, which could lead to the reluctance of persons to pass near
the door or sidelight, which could lead to delays in the evacuation or movement
of persons to a safe place, which could lead to harm to persons.
Intent 2: To limit the probability of excessive glazing in certain
doors and sidelights, which could lead to excessively high temperatures in
the area near the unexposed side of the doors during a fire, which could lead
to an unacceptable radiation exposure, which could lead to harm to persons.
Intent 3: To state the requirements for wired glass and glass block
permitted by Sentence 9.9.4.2.(4) to be installed in fire separations
that separate exits from the remainder of the building. |
