Which approach provides fire protection and life safety as an alternative when a building falls outside common design?

• A. Wet Barrel Hydrant
• B. Performance Based Design
• C. Dry Barrel Hydrant
• D. Ingress

Answer: (B)

When a building can’t meet standard prescriptive requirements, using a performance-based design approach provides fire protection and life safety as an alternative by demonstrating that the project meets or exceeds the same safety goals through analysis and engineered solutions. This method focuses on outcomes—egress times, occupant rescue, detection and suppression capabilities, and control of heat, flame, and smoke—rather than strictly following fixed box-by-box rules. In practice, it involves setting clear safety objectives, selecting appropriate performance criteria, developing engineered solutions (such as specialized detection, compartmentation, smoke management, or tailored evacuation strategies), and using fire models or other analyses to prove the objectives are met. The plan is reviewed and approved by the authority having jurisdiction, with documentation showing there’s an equivalent or better level of protection than the prescriptive code would provide. Hydrant types and access considerations are separate topics related to firefighting readiness and entry, not the method used to achieve life safety through design.
