Predicated Building Performance

6When 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

Take the time to remember FDNY Lt. Joseph Cavaleiri, FF Christopher Bopp and Firefighter James Bohan from Ladder 170
