3.1.5.21.(1)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:
Decorative wood cladding used on the exterior marquee
fascias of storeys having direct access to a street or access route, on buildings described in Sentence
1.3.3.2.(1) of Division A that are required to be of noncombustible construction, where the cladding is fire-retardant-treated wood that has been conditioned in conformance with ASTM D 2898, “Accelerated Weathering of Fire-Retardant-Treated
Wood for Fire Testing,” before being tested in accordance with CAN/ULC-S102,
“Test for Surface Burning Characteristics of Building Materials and
Assemblies.”
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 exempt certain combustible materials from the application
of Sentence
3.1.5.1.(1) if certain conditions are met, on the basis
that the materials are deemed to insignificantly contribute to the growth
and spread of fire.
