In the case of an extra hazard, what is the designated sprinkler coverage?

In the context of fire protection, particularly regarding sprinkler systems, the coverage designated for extra hazards is critical to ensuring effective fire suppression. For areas categorized as extra hazard, the maximum area that a single sprinkler is typically expected to protect is set at 100 square feet. This requirement ensures that the sprinkler system can provide adequate water application to manage the increased fire risks associated with such hazards, which often involve combustible materials or processes that present a higher likelihood of intense fires.

The designation of 100 square feet allows for sufficient sprinkler head operation to effectively combat fires that may occur in these environments. By limiting coverage to this area, fire protection engineers and safety professionals ensure that there is adequate water distribution to mitigate the risk of fire spread, thereby enhancing overall safety.

In comparison, other coverage areas might apply to light and ordinary hazard categories where the risks are considered lower, thus allowing for wider coverage per sprinkler head. However, in the case of extra hazards, the more intensive fire threat necessitates the closer spacing and reduced area of coverage to promote safety and effective emergency response.
