According to NFPA 291, what is the required minimum distance from the center of a hose outlet to the finish grade?

The correct answer, which states that the required minimum distance from the center of a hose outlet to the finish grade is 8 inches, aligns with the guidelines set forth by NFPA 291. This standard is crucial for ensuring that fire hydrants and hose outlets are accessible for effective firefighting operations. By maintaining this minimum height, the design facilitates the connection of hoses and prevents damage or obstructions from surrounding ground surfaces.

Choosing an incorrect measurement would either lead to difficulties when fire personnel are trying to connect hoses or could make the outlet susceptible to flooding, debris accumulation, or accessibility issues. A distance of 8 inches strikes a balance, allowing for functionality while also accommodating various environmental factors. Understanding this requirement is vital for anyone involved in municipal infrastructure or firefighting operations, as it directly impacts emergency response effectiveness.
