(2) Insulating materials and adhesives for pipes, ducts, plenums and other components of heating, air handling, and cooking exhaust systems in hotels shall be noncombustible or shall have fire hazard classification ratings not exceeding flame spread-25, fuel contributed-35, and smoke developed-50, or shall be of some other approved composition.

(3) Where an attic, a crawl space, a space above a dropped corridor ceiling or any other concealed space is used as a plenum, the concealed space shall be lined with noncombustible material, material having fire hazard classifications not exceeding flame spread-25, fuel contributed-35, and smoke developed-50, or other approved material.

EXITS -

35. (1) No separation for an exit stairway shall be breached by a duct or other part of an air handling system.

(2) Despite subsection (1), a lobby or other entrance area that is within a stairway separation may be breached, provided the stairway is separated from the entrance area by a 3/4-hour fire separation.

36. No stairway enclosure or corridor shall be used as a plenum to exhaust air from other areas.

FIRE DAMPERS

37. (1) A fusible-link fire damper shall be installed in an air handling system where a duct or plenum in the air handling system has a cross-section area of 194cm2 or more and passes through,

  (a) a 3/4-hour or greater fire separation, in a hotel constructed after the 1st day of September, 1971;

  (b) the separation of a boiler, furnace, incinerator or fuel-fired space heating appliance;

  (c) the separation of a kitchen; or

39. Cooking appliances from which grease laden vapours emanate in hotel kitchens, other than kitchens in suites, shall have a cooking exhaust system which shall, unless otherwise approved, be provided with,

  (a) a hood or other primary collection device to collect and confine all cooking vapours and residues emanating from the cooking appliances;

  (b) a grease filter or other means of grease extraction;

  (c) a duct from the hood or other primary collection device which shall, unless otherwise approved,

    (i) lead as directly as possible to the outside,

    (ii) be independent and not connected to any other ventilation system, and

    (iii) have adequate openings for inspection and cleaning purposes, equipped with tight fitting doors;
