Required Fire Flow
ISO-style Area Method (legacy convenience formula: Q = 18 x F x sqrt(A)). This is a single named, selectable planning method - it is not presented as a universal code requirement. Confirm your department's adopted method and edition before relying on this estimate.
ℹVerify locally before acting. This tool is a planning and arithmetic aid, not a substitute for training, local SOPs, calibrated instruments, or scene assessment. Confirm critical values independently. Suite status: DRAFT - not yet department-approved for operational use.
When you'd use this: Pre-incident planning or reviewing a new-construction site - estimate the fire flow a building of a given size and construction class would need, to confirm the hydrant system or tanker shuttle can actually supply it before there's ever a fire there.
