What is the maximum distance between pendent/upright sprinkler heads in a moderate hazard occupancy?

• A. 3.6 m
• B. 4.5 m
• C. 6 m
• D. 2 m

Answer: (B)

In a moderate hazard occupancy, the maximum distance between pendent or upright sprinkler heads is indeed 4.5 meters. This standard is derived from fire protection codes that dictate spacing requirements to ensure adequate coverage and effective suppression in environments categorized as moderate hazards, like commercial spaces and light industrial facilities. Moderate hazard occupancies are classified as those that may have a higher likelihood of fire incidents due to potential combustibles or processes involved, necessitating a more significant focus on sprinkler system installation to mitigate those risks. By maintaining a spacing of no more than 4.5 meters between sprinkler heads, the system can effectively control and suppress fires that may occur within the designated area. This measurement is crucial because if the distance between the sprinklers exceeds this standard, there might be gaps in coverage that could lead to ineffective fire suppression, allowing a fire to grow beyond control. Therefore, the regulation ensures that the fire protection system provides adequate response within the room or area being protected.
