In a low hazard occupancy, how many square feet may a single sprinkler cover?

• A. 125 Feet
• B. 350 Feet
• C. 225 Feet
• D. 450 Feet

Answer: (C)

In low hazard occupancies, how much area a single sprinkler is meant to protect is defined by the hazard classification. The lower the hazard, the larger the coverage area per sprinkler can be, because fire growth and water demand are expected to be smaller. For low (light) hazard situations, the standard coverage per sprinkler is 225 square feet. That corresponds to roughly a 15-foot by 15-foot footprint per head, assuming typical ceiling heights and few obstructions. So 225 square feet is the correct guideline for how much area one sprinkler should cover in a low hazard occupancy. The other options fall outside the typical coverage range for low hazard conditions.
