What is the minimum coverage area for a single sprinkler head in a light hazard occupancy?

• A. 100 square feet
• B. 130 square feet
• C. 150 square feet
• D. 200 square feet

Answer: (B)

In light hazard occupancies, the National Fire Protection Association (NFPA) standards dictate that the minimum coverage area for a single sprinkler head is set at 130 square feet. This specification is part of the NFPA 13 standard, which provides guidelines for the design and installation of sprinkler systems. The rationale behind this coverage area ensures that each sprinkler head can effectively provide sufficient water distribution to control potential fire hazards in low-risk environments, such as offices or storage areas with non-combustible materials. The choice of 130 square feet balances adequate coverage with the need for efficient water delivery without unnecessary resource usage or overspray. Choosing a value outside of this range, such as 100, 150, or 200 square feet, would not align with the established requirements for light hazard occupancies, potentially leading to inadequate fire protection or unnecessary complications in system design and performance. Thus, opting for 130 square feet provides both safety and compliance for sprinkler systems in these types of facilities.
