Predicated Building Behavior

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?

There's a great series of photos depicting initial operations at a small-sized (square foot) single family residential occupancy fire that captures fire and smoke behavior, HERE and HERE

Take at look the at this residential fire and interior attack that injured a number of Maryland Firefighters HERE

Take a moment to look back at an incident: On December 18, 1998, Three FDNY Firefighters died in-the line of duty while conducting suppression and rescue operations at fire on the tenth floor of 10-story high-rise apartment building for the elderly. This wind-driven fire event and the lessons-learned contributed directly to the current body of research and new insights on emerging strategies and tactics. NIOSH Report HERE. NIST References HERE
