For a single-story building rated as ordinary hazard and measuring 298,000 square feet, how many fire sprinkler risers are required?

To determine the required number of fire sprinkler risers for a single-story building rated as an ordinary hazard, we refer to the National Fire Protection Association (NFPA) guidelines and other relevant fire safety codes. In general, the number of fire sprinkler risers needed is influenced by factors such as the building's size, occupancy classification, and fire hazard level.

For a single-story ordinary hazard building, guidelines typically suggest that one riser service area can cover a certain number of square feet, often in the range of 50,000 to 75,000 square feet per riser, depending on the specific type of sprinkler system installed and local code requirements. Given the total area of 298,000 square feet, you would divide this area by the maximum coverage area per riser as specified by the applicable codes.

For illustrative purposes, if we consider a coverage threshold of around 50,000 to 75,000 square feet for ordinary hazard settings, we would find that the building exceeds the capacity supported by just a few risers. In this case, when calculating the required risers based on coverage, it becomes evident that at least six risers are necessary to ensure adequate water supply and distribution for effective fire suppression throughout the building.
