标准简介：This International Standard is only one of many tools available for use in fire safety engineering. It is intended
to be used in conjunction with models for analysis of the initiation and development of fire, fire spread, smoke
formation and movement, chemical species generation, transport and decay and people movement, as well as
fire detection and suppression. This International Standard is to be used only within this context.
This International Standard is intended to address the consequences of human exposure to the life threat
components of fire as occupants move through an enclosed structure. The time-dependent concentrations of
fire effluents and the thermal environment of a fire are determined by the rate of fire growth, the yields of the
various fire gases produced from the involved fuels, the decay characteristics of those fire gases and the
ventilation pattern within the structure (see Clause A.1). Once these are determined, the methodology
presented in this International Standard can be used for the estimation of the available escape time.
This International Standard provides guidance on establishing the procedures to evaluate the life threat
components of fire hazard analysis in terms of the status of exposed human subjects at discrete time intervals.
It makes possible the determination of a tenability endpoint, at which time it is estimated that occupants are no
longer able to take effective action to accomplish their own escape (see Clause A.2). The life threat
components addressed include fire-effluent toxicity, heat and visual obscuration due to smoke. Two methods
are presented for assessment of fire-effluent toxicity: the toxic-gas model and the mass-loss model.
Aspects such as the initial impact of visual obscuration due to smoke on factors affecting the time required for
occupants to escape, the toxic effects of aerosols and particulates and any interactions with gaseous fireeffluent
components and adverse health effects following exposure to fire atmospheres are not considered in
this International Standard (see the Introduction).
