COMMERCIAL FIRE BEST PRACTICES, BENCHMARKS AND ACTIONS THAT ARE NOT WELL KNOWN
See Attached for full Description of this sections covered material and Bios.
Some items covered... lecture and flow:
Range pumping deck guns
Commercial water mapping
Why building geometry stream size up, is a make or break extinguishment moment for the first two handlines.
Stream survival comparisons based on volume / velocity
Proper secondary handline selection algorithms that take into consideration volume placement and mobility
FDC pumping with two pressure pump Volumetric Efficiency and then test pressure. Why PSI mode ... critcal RPM tracking. Hitting test pressure why this is critical if fire is firmly established.
How to actually get 250gpm@45psi@89lbs with no nozzle whip or kinking by manipulating back pressure in 2-inc hose.
Hose lay strategy couplings fwd nozzle back is often the right move for break over entry of initial application of handline water from exterior to interior.
How to create fall out without easy primary secondary droplets distribution impacts found in residential compartments
Types of Commercial stream patterns how to apply them.
Opposing stream when where and why it is a often a good thing in Commercial spaces.
Optimization of both simple solid tips and Bladed Nozzles in application regime.
Residential vs Commercial differences exiting, primary entries, ventilation, search, orientation, front door vs all door target of opportunity.. etc
We are looking forward to see you there and let's make these critical metrics better known, understood and shared.
