A system for determining fire danger within a building composed of a plurality of building zones comprises: a human presence detector configured to detect a human presence measurement; a fire detector configured to detect a fire measurement; a gas detector configured to detect gas measurement; a storage device to store at least one of an evacuations plan, flammable material index, and human movement prediction model; a fire danger management system coupled to storage device, the fire danger management system including: a fire danger rating generation module to determine a fire danger rating for each building zone in response to at least one of the evacuations plan, flammable material index, and human movement prediction model; and a fire danger index generation module to determine a fire danger index for each building zone in response to at least one of the fire danger rating, human presence measurement, fire measurement, and gas measurement.
