Fire sprinkler systems are an important part of life safety in buildings. International building codes allow some exceptions when buildings are “fully watered”, such as reducing rated spacing, reducing hydrant flow requirements, increasing exit travel distance, and increasing building height and area. These exceptions are allowed so that in the event of a fire, the sprinkler system will suppress the fire enough that occupants can safely evacuate the building and that the spread of the fire is contained before the fire department has fully arrived to extinguish it.
