Egress Modeling in Health-Care Occupancies

A proposed change for the 2015 edition of NFPA 101, Life Safety Code, would increase  the maximum allowable size of smoke compartments in health-care occupancies from 22,500 sq ft (2,090 sq meters) to 40,000 sq ft (3,700 sq meters) - almost double the size (the maximum travel distance of 200 ft (61 m) to a smoke barrier would remain the same).  This, theoretically, has the potential of nearly doubling the number of patients who might need to be relocated or evacuated in an emergency. The impact of this change needs to be better understood, as the effect on relocation times and facility staffing levels has not been studied. The main goal of this project is to provide input to the technical committee regarding the potential impact of this change, based on the results of computer modeling of various relocation scenarios.
