Sec. 102-80.140  What is meant by ``room of origin''?

    Room of origin means an area of a building where a fire can be 
expected to start. Typically, the size of the area will be determined by 
the walls, floor, and ceiling surrounding the space. However, this could 
lead to unacceptably large areas in the case of open plan office space 
or similar arrangements. Therefore, the maximum allowable fire area 
should be limited to 200 m2 (2000 ft2) including 
intervening spaces. In the case of residential units, an entire 
apartment occupied by one tenant could be considered as the room of 
origin to the extent it did not exceed the 200 m2 (2000 
ft2) limitation.
