Back9.3.2.9.(7)

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:

Marking of treated structural wood elements that are:
  • in termite-prone localities, where the clearance between structural wood elements and the ground is less than 450 mm or not all sides of supporting elements are visible,
  • in termite-prone localities, where a barrier is not installed through finish materials on insulated foundations or not all sides of the finished supporting assembly are visible,
  • in all localities, where the vertical clearance between structural wood elements and the ground is less than 150 mm,
  • in all localities, where
    • the wood elements are not protected from exposure to precipitation,
    • the configuration is conducive to moisture accumulation, and
    • the moisture index is greater than 1.00, and
  • in all localities, where structural wood elements are used in retaining walls and cribbing, and where
    • the retaining wall or cribbing supports ground critical to the stability of building foundations, or
    • the retaining wall or cribbing is greater than 1.2 m in height.
This applies to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].

INTENT:

To facilitate identification at the time of purchase as well as during and after construction.
