What is the fire area in a building?
Fire area appears in the building code mostly in Chapter 9 where it is used as a threshold for requiring either fire separation or fire sprinkler systems. For example, Section 903.2.9, states that one threshold of sprinklering the entire building is when such a building contains a Group S-1 fire area of greater than 12,000 square feet. In this case, the entire building would have to be sprinklered, or fire barriers would have to be constructed to limit each Group S-1 fire area to 12,000 square feet or less. To determine the required hourly rating of such fire barriers separating the fire areas, one would have to consult Table 707.3.10. For separating Group S-1 fire areas from Group S-1 fire areas, a 3 hour rated fire barrier is required.
