F10

To facilitate the timely movement of persons to a safe place in an emergency.

Objective:

OS3.1, OS3.7

APPLICATION:

Collapsibility of a revolving door used as an exit from the ground floor level.

This applies, in buildings described in Sentence 1.3.3.2.(1) of Division A, to:

interior and exterior exits, as stated in Appendix Note ., and
exits serving floor areas that are intended for occupancy, including mezzanines as stated in Sentence 3.4.2.2.(1).

This also applies to:

ramps, stairways and passageways used by the public as access to exits, as stated in Appendix Note .,
tents and air-supported structures, as stated in Sentences 3.1.6.1.(1) and 9.10.1.2.(1), and
revolving doors used in exits in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], as stated in Sentence 9.9.6.4.(3).

INTENT:

To limit the probability that the use of a revolving exit door in an emergency situation will lead to congestion or the buildup of persons at the doorway, which could lead to:

persons being crushed, which could lead to harm to persons, and
delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.

ATTRIBUTION:

Functional Statement:

F10

To facilitate the timely movement of persons to a safe place in an emergency.

F12

To facilitate emergency response.

Objective:

OS3.7

APPLICATION:

Hinged doors adjacent to a revolving door used as an exit from the ground floor level.

This applies, in buildings described in Sentence 1.3.3.2.(1) of Division A, to:

interior and exterior exits, as stated in Appendix Note ., and
exits serving floor areas that are intended for occupancy, including mezzanines as stated in Sentence 3.4.2.2.(1).

This also applies to:

ramps, stairways and passageways used by the public as access to exits, as stated in Appendix Note .,
tents and air-supported structures, as stated in Sentences 3.1.6.1.(1) and 9.10.1.2.(1), and
revolving doors used in exits in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], as stated in Sentence 9.9.6.4.(3).

INTENT:

To limit the probability that:

persons will not have a choice of an alternative exit doorway in the case of the revolving doorway being blocked or obstructed in an emergency situation, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons,
alternative exit doorway openings will be of insufficient size to permit efficient evacuation or movement to a safe place in an emergency situation, which could lead to congestion at the doorway openings, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons, and
congestion will occur at the alternative doorway openings, which could lead to emergency responders being delayed in gaining access to floor areas, which could lead to delays or ineffectiveness in emergency response operations, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.
