Study Notes
Fire Attack from Standpipes
- Phoenix's growth leads to an increase in large buildings and multi-story constructions, necessitating effective fire suppression systems.
- Firefighting personnel need to understand essential equipment for executing fire attacks from standpipes.
- Building types include commercial and residential, spanning from single-story to over 40 stories.
- Standpipe firefighting requires consideration of building systems, size, layout, and complexity.
- Key considerations for standpipe fire attacks include:
Water Supply and Pressure
- Ensure adequate water supply using building fire systems or engine company pumps.
- Provide high pump discharge pressures to compensate for malfunctioning or inadequate building fire pumps.
- Tandem pumping and high-pressure supply hoses are vital for effective operations.
Hose and Nozzle Management
- Maintain sufficient water pressure to the highest and farthest standpipe outlet based on the hose and nozzle specifications.
- Determine and manage adequate flow rates at the nozzle as part of the firefighting strategy.
Flow Rates and Standards
- Follow NFPA 13E and NFPA 1710 guidelines for gallons per minute (GPM) during initial and subsequent firefighting efforts from standpipe connections.
- Ensure flow capabilities from standpipes on multiple floors are effectively managed and executed.
System Components and Functionality
- Understand pressure-reducing and pressure-restricting devices within standpipe systems and their impacts on firefighting efforts.
- Strategically stretch hose lines from standpipe connections to fire locations, considering limitations imposed by smoke and heat in stairwells and common areas.
