What is the maximum sprinkler spacing for an extra hazard system with a density greater than or equal to .25?

In an extra hazard system, the maximum sprinkler spacing is crucial for ensuring effective coverage and adequate water distribution to control potential fire risks adequately. According to the relevant standards and guidelines, when the density exceeds or is equal to .25 gpm/ft² (gallons per minute per square foot), the allowable maximum spacing for the sprinklers is specifically determined.

For a density of .25 gpm/ft², the maximum area that each sprinkler can protect is 100 square feet. This ensures that enough water can be delivered to the fire area in the event of a fire, effectively controlling or extinguishing it. The calculation of maximum spacing is vital to maintain compliance with safety regulations and to optimize the fire protection system's performance.

By adhering to a maximum spacing of 100 square feet in this particular scenario, fire protection professionals can ensure that the sprinkler system operates within acceptable parameters to safeguard lives and property in environments designated as extra hazards.
