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.

where
- the supported length of joists bearing on such beams does not exceed 5 m, and
- the live load on any floor does not exceed 2.4 kPa,
- beams or header joists carrying loads from not more than 2
levels of wood-frame balconies, decks or other accessible, exterior platforms,
