considering the unique circumstances of each building or occupancy. While effective in
standard scenarios, prescriptive codes often lack flexibility and may not adequately
address complex or innovative designs. Performance-based fire protection (PBFP) shifts
this paradigm by focusing on achieving defined safety objectives rather than strictly
following predetermined rules. It involves sophisticated modeling, risk assessment, and
