The document defines fire safety engineering as the application of engineering principles, rules, and expert judgement based on scientific understanding of fire phenomena, fire effects, and human behavior. The goal is to save lives, protect property, preserve the environment and heritage, quantify fire hazards and risks, and evaluate optimal protective measures to limit fire consequences. Fire safety engineering uses a performance-based design approach rather than a prescriptive approach, assessing whether a design meets safety goals like allowing adequate escape time.

Fire Safety Engineering, la définition?
Exemple d’une définition : (source : ISO)
“The application of engineering principles, rules and expert
judgement based on a scientific appreciation of the
phenomena, of the effects of fire, and of the reaction and
behaviour of people, in order to:
❙ save life, protect property and preserve the environment and
heritage;
❙ quantify the hazards and risk of fire and its effects;
❙ Evaluate analytically the optimum protective and preventative
measures necessary to limit, within prescribed levels, the
consequences of fire”
