Final answer:
The provided question concerns the requirements for smoke barriers in Group I-3 occupancies relating to resident safety during a fire, but without the necessary occupant load figure, a precise answer cannot be given.
Step-by-step explanation:
The question pertains to the requirements for smoke barriers in Group I-3 occupancies, which align with regulations set forth to ensure the safety and well-being of residents in such buildings. These smoke barriers are crucial in the event of a fire, helping to prevent the spread of smoke and providing a safer environment for evacuation or sheltering in place. However, without the correct occupant load figure provided in the question, it is not possible to give an accurate answer about the specific occupant load that necessitates the division into at least two smoke compartments. Having detailed information on the proper building codes and regulations would also be necessary to provide a full and accurate response.
Occupancies in Group I-3 refers to buildings that are used for housing residents for sleeping or other activities, with a specific occupant load. These buildings are typically multi-story structures.
Smoke barriers are physical barriers within the building that are designed to prevent the spread of smoke in the event of a fire or other emergency. They divide the building into compartments to contain smoke and allow residents to safely evacuate.
Smoke compartments are designated areas within the building that are separated by smoke barriers. In the case of Group I-3 occupancies, every story occupied by residents for sleeping, or any other story with an occupant load of a certain number of people, must be divided into at least two smoke compartments. This helps to limit the spread of smoke and provides additional time for evacuation.
