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

In high hazard occupancies, the maximum distance between pendent or upright sprinkler heads is set to ensure adequate coverage and effective firefighting capabilities in environments where a rapid fire spread is a significant risk. The chosen value of 3.6 meters aligns with the standards outlined by relevant fire protection codes, such as NFPA 13, which govern the requirements for sprinkler system installation in various types of occupancies, including those classified as high hazard.

Maintaining the specified distance is critical for ensuring that, in the event of a fire, the sprinklers can adequately control or extinguish flames before they develop into more severe hazards. This distance allows for the optimal distribution of water, preventing any potential gaps in coverage that could lead to ineffective fire suppression. In contrast, the distances presented in the other options do not comply with established guidelines for high hazard environments, which necessitate a tighter spacing to address the higher risk involved.
