ically as design and construction progress and before and during major plant modifications. (2) The fire hazard analysis should be a systematic study of (a) all elements of the fire protection program being proposed to ensure that the plant design has included adequate identification and evaluation of potential fire hazards and (b) the effect of postulated f~res relative to maintaining the ability to perform safe shutdown functions and minimizing radioactive releases to the environment. (3) Experienced judgement is necessary to identify fire hazards and the consequences of a postulated fire starting at any point in the plant.- Evaluation of the consequences of the postulated fire on nuclear safety should be performed by persons thoroughly trained and experi- enced in reactor safety. The person conducting the analysis of fire hazards should be thoroughly trained and experienced in the principles of industrial fire prevention and control and in fire phenomena from fire initiation, through its development, to propagation into adjoining spaces. The fire hazard analysis should be conducted by or under the direct supervision of an engineer who is qualified for Member grade in the Society of Fire Protection Engineers. (4) The fire hazard analysis should separately identify hazards and provide appro- priate protection in locations where safety-related losses can occur as a result of: 1.120-5 (a) Concentrations of combustible contents, including transient fire loads due to combustibles expected to be used in nurmal operations such as refueling, maintenance, and modifica- tions- (b) Continuity of combustible contents, furnishings, building materials, or combinations thereof in configurations conducive to fire spread; (c) Exposure fire, heat, smoke, or water exposure, including those that may necessitate evacuation from areas that are required to be attended for safe shutdown; (d) Fire in control rooms or other locations having critical safety-related functions; (e) Lack of
