Fire Attack Equipment
- Phoenix Fire Department utilizes flexible hose and nozzle packages tailored to effectively combat residential and commercial fires.
- Firefighters are trained to be proficient in using these tools and understanding their specific capabilities.
Operational Expectations
- Company Officers and Sector Officers must assess and implement the most effective fire attack operations.
- Incident Commanders are responsible for determining overall fire attack requirements and guiding tactical positions with the incident action plan.
Water Flow Standards
- Water flow standards for fire attacks are as follows:
- Residential Fires: 150 GPM (1.75” hose lines with automatic nozzles).
-
Commercial Fires:
- 250 GPM (2” and 2.5” hose lines with fixed gallonage or smooth bore nozzles).
- 500 GPM (portable appliances).
- 600+ GPM (deck gun or ladder pipe).
- These standards comply with or exceed national best practices, specifically NFPA 1700 and 1710.
Hose and Nozzle Packages
- Phoenix Fire Engine Companies are equipped with various hose and nozzle packages:
-
1 ¾” Hose Line with Automatic Nozzles (Minimum x2):
- Hose lengths: 150’ crosslay, 200’ crosslay, 100’ to 150’ front bumper line.
- Nozzle operates at 75/45 psi nozzle pressure for flow between 70 to 200 GPM.
-
2” Hose Line with Smooth Bore Nozzles (x1):
- Hose length: 200’ crosslay or rear mount based on apparatus design.
- Nozzle with a 1 1/16” tip providing 240 GPM at 50 psi nozzle pressure.
-
2 ½” Hose Line with Smooth Bore Nozzles (1 or 2 based on apparatus):
- Hose length: 200’ rear mount.
- Nozzle with a 1 3/16” tip offering 300 GPM at 50 psi nozzle pressure.
- Optional Blitz Monitor with solid bore or peripheral tips capable of up to 500 GPM.
-
1 ¾” Hose Line with Automatic Nozzles (Minimum x2):
Fire Attack Equipment and Standards
- The Phoenix Fire Department employs a versatile selection of hose and nozzle packages for effective fire attacks in various settings.
- Firefighters must be proficient in the use and understanding of hose and nozzle tools for optimal effectiveness.
Roles and Responsibilities in Fire Attack
- Company Officers and Sector Officers must assess and guide fire attack operations effectively.
- Incident Commanders oversee the overall fire attack strategy and direct tactical positions based on an incident action plan.
Water Flow Standards
- Residential fire attack standard: 150 GPM (2.5 gallons per second) using 1.75" hose lines with automatic nozzles.
- Commercial fire attack standards:
- 250 GPM (5 GPM) with 2" or 2.5" hose lines and fixed or smooth bore nozzles.
- 500 GPM (8 GPM) through portable appliances.
- 600+ GPM (10+ GPM) using deck guns or ladder pipes.
- Standards in place align with national best practices and NFPA 1700 & 1710 guidelines.
Hose and Nozzle Configurations
- Minimum equipment for Phoenix Fire Engine Companies:
- Two 1¾” hose lines with automatic nozzles.
- Hose lengths: 150’ and 200’ crosslay, and 100’ to 150’ front bumper line.
- Automatic nozzles operate at 70 to 200 GPM (75/45 psi).
- One 2” hose line with a smooth bore nozzle.
- Hose length: 200’ crosslay or rear mount.
- Smooth bore nozzle with a 1 1/16” tip (240 GPM at 50 psi).
- One or two 2½” hose lines with smooth bore nozzles.
- Hose length: 200’ rear mount.
- Smooth bore nozzle with a 1 3/16” tip (300 GPM at 50 psi).
- Blitz Monitor can achieve up to 500 GPM.
- Two 1¾” hose lines with automatic nozzles.
Nozzle Reaction and Operational Safety
- Nozzle reaction is the force exerted by the nozzle on the firefighter, with a standard of 70 lbs for single firefighter operations.
- Situations exceeding 70 lbs necessitate additional firefighters or support for safe operation.
- The preferred distribution of firefighters based on hose size and resulting nozzle reaction:
- 1¾” hose with 75 psi nozzle: 1 firefighter operation (average 65 lbs nozzle reaction).
- 1¾” hose with 45 psi nozzle: 1 firefighter operation (average 60 lbs nozzle reaction).
- 2” hose with 1 1/16” nozzle: 2 firefighters minimum (average 85 lbs).
- 2½” hose with 1 3/16” nozzle: 3 firefighters minimum (average 110 lbs).
Water Supply Considerations
- Standard Phoenix Engine Company apparatus carries around 500 gallons of water, with slight variations by apparatus generation.
- Establishing an uninterrupted water supply is vital for supporting fire attacks in declared working fires.
- Certain conditions allow first due Engine Companies not to set up a hydrant supply line, including:
- Unknown fire locations or routes.
- Fire in high-rise buildings.
- Immediate rescue situations.
- Situations demanding rapid fire attack before initial supply lines can be established.
- Incident Commanders and Sector Officers are accountable for ensuring adequate water supplies are available for fire attack operations.
