FIRE SAFETY PRINCIPLES
Fire Engineering Approach To Meet Intent of Principle
Principle
Fundamental Principle - Comprehensive Fire Strategy
– Development of the fire strategy to be an iterative process, live throughout the design and construction stages of the project, whereby the end product is to meet this fundamental principle. – Competent professional to decide the approach to address the principles below and develop the comprehensive fire strategy. – Professional to demonstrate their competency and relevant experience.
A comprehensive fire safety strategy should be developed by someone with relevant competency and experience for each building that follows the below principles. Furthermore, the strategy should establish and clearly articulate maintenance and management plans, as well as a clear and explicit definition of all dependencies, conflicts, and redundancies between the different protection strategies used.

Adequate Risk to Health and Safety
Demonstrate the adequate risk to health and safety through either of:
All buildings, independent of what materials are used and their combustibility, shall be demonstrated to have an equal and adequate risk to the health and safety of people (including fire brigades) in or around a building in the event of a fire.
– Responding to the principles within this table, where a comparative approach is embedded (the proposed acceptance criteria being with reference to a non- combustible building). – Approaching from first principles (ie without following the comparative approach in this table). – Consider the reliability of the fire safety measures proposed within the fire strategy. – Ensure these are not elevated or relied upon more so than for a non-combustible building, unless a higher reliability can be evidenced for the specific case of a mass timber building.

Adequate Risk to Health and Safety
No greater reliance should be placed on fire safety measures in a combustible structure than would be expected for a non-combustible structure unless they have an demonstratably higher reliability.

Assumed Redundancies for Life Safety Design
Sprinklers are to be treated as a redundancy in the fire safety strategy, and therefore should not be included in the assessment of adequacy of a fire safety strategy. The fire safety strategy must provide an adequate level of safety independent of the presence of sprinklers.
– Quantify consequences of sprinkler failure, by undertaking an analysis that doesn’t include the benefit of sprinklers. – Make design decisions based on the outcomes of the analysis and the acceptable risk.
