3.1.5.8.(3)ATTRIBUTION:
Most technical provisions of the BC Fire Code describe how the code’s objectives and functional statements are achieved. However, some provisions, like this one, do not relate directly to a code objective. The following analysis is provided to assist in understanding of the provision.
APPLICATION:
Combustible subfloors and combustible finished flooring used in flooring systems for raised platforms formed by wood members more than 50 mm but
not more than 300 mm high applied directly to or set into a noncombustible floor slab, in buildings described in Sentence
1.3.3.2.(1) of Division A that are required to be of noncombustible construction.
This also applies to buildings to which Part 9 applies [see Sentence
1.3.3.3.(1) of Division A for application
of Part 9] that are required to be of noncombustible construction, as stated in Sentence
9.10.6.1.(1).
INTENT:
To clarify that certain combustible materials are permitted
in buildings on the basis that the materials are deemed to insignificantly
contribute to fire growth and spread.
