All new building construction must have an approved water supply that meets the minimum fire flow requirements necessary for fire protection. The exact fire flow depends on factors such as building size, occupancy type, construction materials, and hazard levels.
Reference to Fire Inspector Documentation:
1. 2021 International Fire Code (IFC) – Section 507.1 (Required Water Supply)
IFC 507.1 states that an approved water supply capable of providing the required fire flow must be installed in all new construction projects.
The required fire flow varies based on building classification and must be determined by the authority having jurisdiction (AHJ).
2. 2021 IFC – Appendix B (Fire-Flow Requirements for Buildings)
Table B105.1(2) provides fire flow requirements based on construction type and building area.
Fire flow must be calculated according to the ISO (Insurance Services Office) Fire Suppression Rating Schedule.
Detailed Explanation of Answer Choices:
Option A (Correct): The fire flow requirement is determined based on the building and fire protection needs, making this the correct answer.
Option B (Incorrect): A static pressure of 40 psi at each hydrant is not a universal requirement, as fire flow is the primary factor.
Option C (Incorrect): A static pressure of 60 psi is not the fire code’s general requirement; fire flow is the priority.
Option D (Incorrect): 250 gallons per minute (GPM) at a fire-access outlet is not an overall fire code requirement for all buildings—it depends on the structure’s classification.
Thus, the correct and verified answer is: A. The required fire flow for fire protection.
