Components of Step 1: Review the architecturaldesign of the building★★★★a) building characterization– i.e. the layout and geometry of the building, details of the construction, thenature and extent of the loads acting on the structure (e.g. dead loads andimposed loads) and the degree of fire loading presentb) environmental lifl influences– such as wind and snow, which influence fire safety design through theireffect on structural load levels, smoke ventilation systems and the natureof externalflame a eenvelopes issuing from the ewindows of the ebuildingc) occupant characterization– i.e the type of occupancy, the building population and its distribution, thelikelihood of the fire alarm being raised manually, the type of firedetection and alarm systemd) management of fire safety– i.e. the likely extent and nature of management in the building.IDRiM'09 20
Components of Step 5: Identification ofAcceptance Criteria★ Criteria against which the adequacy of adesign can be judged using data determinedby one or more of the following methods:– deterministic (including, when appropriate,safetyfactors);– probabilistic (risk-based);– comparative criteria;– financial criteria.IDRiM'09 21
