This paper describes improvements which have been made
in the CFAST model of fire growth and smoke transport
for compartmented structures. In particular, we are
interested in the ability to model the movement of toxic
gases from the room of origin of a fire to a distant
compartment. The newest phenomena in the model are
vertical flow and mechanical ventilation. Finally, we
have improved the radiation transport scheme which
affects energy distribution, and therefore the buoyancy
forces. These are very important in actual situations
relevant to fire growth and smoke propagation, as is
