Notes to Table 3.1.3.A:

(1)     Section 3.3 contains requirements for the separation of occupancies and tenancies that are in addition to the requirements for the separation of major occupancies.

(2)     See Sentence 3.1.3.2.(2).

Table 3.1.3.A. has been edited to show only the requirements for Group A occupancies, as only this is relevant to the Fire Code reference.  Section 3.3, "Safety Requirements Within Floor Areas" that is referenced in the Notes to Table 3.1.3.A. can be found in the current edition of the Building Code and is therefore not reproduced in this Appendix.

3.1.4.4.  The requirements for heavy timber construction are essentially unchanged since 1986 and can be found in the current edition of the Building Code.

3.1.4.5.  This Article deals with buildings that are required to be of noncombustible construction and the combustible elements that are allowed to be used in the construction of these buildings.  This information can be found in the current Building Code and is therefore not reproduced in its entirety in this Appendix.

(2)(a)(iv)  This Subclause requires that wood furring strips not exceed 38 mm by 38 mm and be attached directly to a continuous noncombustible backing.

(3)  Combustible millwork, interior cladding and finishing materials shall be limited to

(g)  interior wall finishes other than foamed plastics that

(i)   are not more than 25 mm in thickness, and

(ii)  have a flame-spread rating of not more than 150 on any exposed surface, or any surface that would be exposed by cutting through the material in any direction,

(h)  interior ceiling finishes other than foamed plastics that

(i)   are not more than 25 mm in thickness, except for exposed fire-retardant treated wood battens, and

(ii)  consist of a material having a flame-spread rating of not more than 25 on any exposed surface or on any surface that would be exposed by cutting through the material in any direction or fire-retardant treated wood, except that not more than 10 percent of the ceiling area within each fire compartment is permitted to have a flame-spread rating of not more than 150.

3.1.5.1.(1)  Except as provided in Sentences (2) and (3), where a material, assembly of materials or a structural member is required to have a fire-resistance rating, the rating shall be determined on the basis of the results of tests conducted in conformance with CAN4-S101, "Standard Methods of Fire Endurance Tests of Building Construction and Materials".

(2)  A material, assembly of materials or a structural member may be assigned a fire-resistance rating on the basis of Chapter 2, "Fire Performance Ratings" of the Supplement to the NBC 1985.

(3)  Not relevant to Fire Code reference.

3.1.5.2.(1)  Floor, roof and ceiling assemblies shall be rated for exposure to fire on the underside.

(2)  Firewalls and interior vertical fire separations shall be rated for exposure to fire on each side.

(3)  Exterior walls shall be rated for exposure to fire from inside the building.

This Appendix contains extracts from the 1990 Building Code (O. Reg. 413/90) as referenced in Sections 9.5, 9.6 and 9.7 in Division B of the Fire Code.  The complete quote is provided wherever possible.  In some cases, the Building Code reference is very lengthy and thus only the relevant portions have been reproduced.  Information in italics contains editorial notes rather than direct quotes from the Building Code.

 

EXTRACTS FROM SECTION 3.1

3.1.4.6.  The requirements for heavy timber construction are essentially unchanged since 1990 and can be referenced in the current edition of the Building Code.

3.1.5.  Subsection 3.1.5. deals with buildings that are required to be of noncombustible construction and the combustible elements that are allowed to be used in the construction of these buildings.  This information can be found in the current Building Code and is therefore not reproduced in its entirety in this Appendix.

3.1.5.3.(2)  Combustible roof sheathing and roof sheathing supports installed above a concrete deck are permitted on a building required to be of noncombustible construction provided

(a)  the concrete deck is not less than 50 mm thick,

(c)  the roof space is divided into compartments by fire stops in conformance with Article 3.1.11.5.,

(d)  openings through the concrete deck other than noncombustible roof drains and plumbing piping are protected by masonry or concrete shafts constructed as fire separations having a fire-resistance of not less than 1 h and extending from the concrete deck to not less than 150 mm above the adjacent roof sheathing,

(e)  the perimeter of the roof is protected by a noncombustible parapet extending from the concrete deck to not less than 150 mm above the adjacent sheathing, and

(f)   except as permitted in Clause (d), the roof space does not contain any building services.

3.1.5.6.  Wood nailing elements attached directly to or set into a continuous noncombustible backing for the attaching of interior finishes, are permitted in a building required to be of noncombustible construction provided the concealed space created by the wood elements is not more than 50 mm thick.
