9.3.2.8.(1) | Application | Intent |
| OS2 | OP2 | OH4 | OH1 | OS1 | OS3 |
| Objective | OS1 Fire Safety |
| Attribution | |
| Application | Application 1: Size tolerances for wood joists, rafters, lintels
and beams, up to 5% less than the actual Canadian standard sizes, in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9]. |

| Intent | Intent 1: To limit the probability of the failure to adjust spans
for undersized joists, rafters, lintels or beams, which could lead to inadequate
strength or rigidity, which could lead to an inability to resist expected
gravity, lateral or wind uplift loads. Where lumber is
used in assemblies that are required to provide fire resistance, this is to
limit the probability of the compromised fire resistance of the assembly,
which could lead to harm to persons.
