Final answer:
In nonsprinklered Group A occupancies, the maximum allowed travel distance to an exit door is typically 200 feet, as specified in the International Building Code (IBC), but this can vary based on local code amendments.
Step-by-step explanation:
In Group A occupancies, the International Building Code (IBC) specifies that exits and aisles must adhere to certain requirements to ensure safe egress in case of emergency. One of these requirements entails that the travel distance to an exit door in a nonsprinklered building should be no greater than a specific number of feet, measured along the line of travel. The exact travel distance limit can vary based on the edition of the code being referenced and local modifications. However, commonly, the maximum allowable travel distance in a nonsprinklered Group A occupancy is typically 200 feet.
It is important to consult the local building code or fire code based on the version of the IBC adopted by that jurisdiction for the most accurate measure. Local jurisdictions can have amendments to the base IBC that could change this distance. In addition, if any area within such a building is equipped with an approved automatic sprinkler system, the allowable travel distance to an exit can be increased.
