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:

Automatic sprinkler system in a storey in which more than 10% of the area is classified as a Group A, Division 3 major occupancy. This applies in buildings whose building area is restricted to:
This applies to buildings to which Part 3 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 3].

INTENT:

To exclude the upper storeys of a building from the requirements of automatic sprinkler system installation on the basis that Articles 3.2.2.20. to 3.2.2.83. would not otherwise require sprinkler installation.

Functional Statement:

F02

To limit the severity and effects of fire or explosions.

F04

To retard failure or collapse due to the effects of fire.

Objective:

This applies to buildings to which Part 3 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 3].

INTENT:

To limit the probability that loadbearing walls, columns and arches exposed to fire will prematurely fail or collapse, which could lead to the failure or collapse of supported floor or roof assemblies during the time required to achieve occupant safety and for emergency responders to perform their duties, which could lead to harm to persons.
