150 Foot Rule

Firefighters should not operate over 150 feet into a structure during firefighting operations to ensure safe retreat before low air alarms activate.
This guideline was established following the Line of Duty Death (LODD) of Firefighter Brett Tarver by the Phoenix Fire Department.
The 150-foot limit is based on standard attack line lengths and SCBA (Self-Contained Breathing Apparatus) air capacity, allowing time for ingress, work, and egress.
Several factors can affect the maximum safe operating distance inside a structure:
- Smoke and fire conditions
- Building construction and layout
- Type of occupancy
- Interior obstacles
- Physical effort required to advance, which can increase air consumption rate.
For mid-rise and high-rise buildings, the 150-foot rule applies from the exterior entrance or other protected interior access points to the end of the hoseline.
The distance is measured from any area of safe refuge, including stairwells and landings, which can be secured to minimize smoke and fire intrusion.
Areas of safe refuge can include:
- Stairwells that can be protected with doors
- Spaces with standpipes for fire hose connections that can be pressurized to keep smoke and fire out.

This quiz covers the 150 Foot Rule established by the Phoenix Fire Department, which dictates safe operational limits for firefighting within a structure. Understanding this guideline is crucial for fire safety and ensuring the safety of firefighters during operations. Test your knowledge on its implementation and importance.
