(2) The size of an opening in an interior fire separation, even where protected with a closure, shall not exceed 22 m², with no dimension greater than 6 m, when the fire compartments on both sides of the fire separation are sprinklered.

(1) Every swing type door in a fire separation shall be equipped with a latch.

(1) Except as described in Sentence (2), every door in a fire separation shall have a self-closing device.

(2) Self-closing devices are not required between public corridors and suites in business and personal services occupancies, except in,

(1) Except as permitted in Sentences (2) to (5) and Sentence 9.10.5.1.(4)v1, a duct that penetrates an assembly required to be a fire separation with a fire-resistance rating shall be equipped with a fire damper in conformance with Articles 3.1.8.4. and 3.1.8.9.

(2) A fire damper is not required where a noncombustible branch duct pierces a required fire separation provided the duct,

(a) has a melting point not below 760°C,

(b) has a cross-sectional area less than 0.013 m², and

(c) supplies only air-conditioning units or combined air-conditioning and heating units discharging air at not more than 1 200 mm above the floor.

(3) A fire damper is not required where a noncombustible branch duct pierces a required fire separation around an exhaust duct riser in which the air flow is upward provided,

(a) the melting point of the branch duct is not below 760°C,

(b) the branch duct is carried up inside the riser at least 500 mm, and

(c) the exhaust duct is under negative pressure as described in Article 9.10.9.18.

(4) Noncombustible ducts that penetrate a fire separation separating a vertical service space from the remainder of the building need not be equipped with a fire damper at the fire separation provided,

(a) the ducts have a melting point above 760°C, and

(b) each individual duct exhausts directly to the outside at the top of the vertical service space.

(5) A duct serving commercial cooking equipment and piercing a required fire separation need not be equipped with a fire damper at the fire separation.

(1) Fire stop flaps in ceiling membranes required in Sentence 9.10.5.1.(4)v1 shall be constructed in conformance with Supplementary Standard SB-2.
