Intermediate hydrants are required if distance between intersections exceed ______ to ______ ft.

Intermediate hydrants are required if distance between intersections exceed ______ to ______ ft.

• A. 250 to 300 ft
• B. 350 to 400 ft
• C. 450 to 500 ft
• D. 500 to 550 ft

Answer: (B)

Hydrant spacing along streets is planned to keep water access fast and hose layouts practical during a fire. When the distance between intersections gets long, a single hydrant can’t reliably serve the area quickly or support multiple hose lines, so placing an intermediate hydrant helps ensure any point along the street is within easy reach for suppression operations. The typical guideline used is that intermediate hydrants are added when those spans exceed about 350 to 400 feet. This range balances the cost of installing more hydrants with the need for swift water access and manageable hose deployments, keeping firefighting actions efficient. Distances well below or above this range don’t align with common practice, which is why 350 to 400 ft is the best fit.
