When we look at various buildings and occupancies, past operational experiences; those that were successful, and those that were not, give us experiences that define and determine how we access, react and expect similar structures and occupancies to perform at a given alarm in the future. Naturalistic (or recognition-primed) decision-making forms much of this basis.

We predicate certain expectations that fire will travel in a defined (predictable) manner that fire will hold within a room and compartment for a given duration of time, that the fire load and related fire flows required will be appropriate for an expected size and severity of fire encountered within a given building, occupancy, structural system. That may be true for conventional or legacy structures, but what about modern construction and engineered structural systems? Same expectations?.......

What do you think?
Take at look the at the residential fire and interior attack that injured a number of Maryland Firefighters HERE
