Engineering Analysis (Fire Hazard/Fire Risk Assessment)
Engineering Analysis (Fire Hazard/Fire Risk Assessment) : An analysis that evaluates all the various factors that affect the fire safety of the system or component. A written report of the analysis shall be submitted to the authority indicating recommended fire protection method(s) that will provide a level of fire safety commensurate with this standard. The engineering analysis of the ventilation system shall include a validated subway analytical simulation program augmented as appropriate by a quantitative analysis of airflow dynamics produced in the fire scenario, such as would result from the application of validated computational fluid dynamics (CFD) techniques. The results of the analysis shall include the no-fire (or cold) air velocities that can be measured during commissioning to confirm that the ventilation system as built meets the requirements determined by the analysis
