In this study, the dangers surrounding vehicular fires were identified by means of statistical analysis of the national fire information system. The analysis was conducted on the operation time of the sprinkler fire extinguisher, which plays the most essential role during the initial fire extinguishing attempt, in case of a fire outbreak. A simulation was created using the application guidelines pertaining to a sprinkler head located close to a beam as provided in NFSC 103. The operation time of the sprinkler head was analyzed for the case of a parking lot fire where a fan was operated. Fire Dynamics Simulator was used as the simulation program. Performance-based design (PBD) that is introduced to secure the fire safety of buildings requires engineering analysis such as simulation.
