What must smoke barriers in Group I-1, Condition 2, subdivide every story used by persons for?

Smoke barriers in Group I-1, Condition 2, are designed specifically to enhance the safety of occupants in facilities such as residential care facilities, health care institutions, and similar environments where individuals may have limited mobility or require assistance. These barriers help compartmentalize areas within the building to prevent the spread of smoke in the event of a fire, thus allowing for safe evacuation and protecting the health of the residents.

The requirement for smoke barriers to subdivide every story used by persons can include areas where individuals are receiving care, treatment, and sleeping. Each of these functions serves a critical role in the daily lives of the occupants, and thus, the smoke barriers must accommodate all of these areas. This comprehensive approach ensures that safety measures are in place for everyone, regardless of their specific needs or activities within the facility.

By addressing all potential uses of the spaces, the regulations ensure a higher level of safety and a more effective response to emergencies in Group I-1, Condition 2 occupancy scenarios.
