No more than three.

4 Person RIT stages where?

Two floors below the fire floor

EMS Branch Stages Where?

Three floors below fire floor

4 Branches of Logistics Section

1. Ground Support 2. Services 3. Staging 4. Stairwell Support

Apparatus Staging Group is Established where?

No less than 200' from structure, supervised by first arriving engine officer

Resource Group is staged where and how do firefighters shuttle equipment?

- Two Floors below fire floor - Firefighters should be located every two flors and act as an equipment shuttle

Elevator Operations: Maximum amount of firefighters in elevator

6 with the addition of an elevator operator

Elevator Operations: Equipment taken in elevator

- PPE/SCBA - Forcible Entry Tools, - Hose and standpipe kit - Flashlights - Radio - Fire phone

Elevator Operations: How often do you stop the elevator car?

-Every fifth floor

Elevator Operations: How far below the fire floor must you stop and exit?

Minimum of two floors below fire floor

Elevator Operations: Phase 1 and Phase 2 building height requirements

- Phase 1 required in buildings under 75' tall - Phase 2 required in buildings greater than 75'

How often do elevators malfunction during emergency conditions?

30% of the time

Standpipe Systems: What types are the most common?

-Automatic and wet

Standpipe Systems: Class 1 standpipe specifications:

- Designed for use by firefighters - Outlets are 2 1/2" - Primary standpipe supplied with 500 GPM capacity

Standpipe Systems: Class 2 standpipe specifications

- Designed for occupant use - Outlets are 1 1/2" - 100 GPM capacity

Standpipe Systems: Class 3 Standpipe Specifications

-Provide both 2 1/2" and 1 1/2" outlets

Standpipe Systems: Where are firepumps usually located?

-Building's lowest floor

Standpipe Systems: Pre 1993 Allowable flow pressure Flow restricting device required Pressure reducing valve required

Pre 1993 Allowable flow pressure 65-100 PSI Flow restricting device required Residual Pressure 100-175 PSI Pressure reducing valve required Static Pressure \> 175 PSI

Standpipe Systems: 1993 and after Allowable flow pressure Flow restricting device required Pressure reducing valve required

Allowable flow pressure 100-175 PSI Flow restricting device required Optional as long as static pressure is \< 175 PSI Pressure reducing valve required Static Pressure \> 175 PSI

Standpipe Systems: Maximum separation of standpipes

130' (100' of working hose and 30' fire stream)

Standpipe Systems: How close must ffire hydrants be to a standpipe FDC?

40'-100'

Standpipe Systems: Pump discharge pressure is determined by adding

100 psi + 5 psi above the first floor

Smoke Control and Ventilation: Dedicated zoned system

All air movement equipment is installed soley for providing smoke control

Smoke Control and Ventilation: Non-dedicated system

Air movement system is shared with another system, like HVAC

Smoke Control and Ventilation: Goals of HVAC smoke management

- Limit fire/smoke spread - Prevent system from intensifying and spreading fire - Provide fresh air to occupants and firefighters

Smoke Control and Ventilation: HVAC 3 main subsystems

- Processing System - Supply System - Return System

Smoke Control and Ventilation: HVAC Size-up

1. Location of mechanical equipment room 2. Number of zones 3. Presence of any special systems 4. Location of HVAC operational controls 5. Number of return shafts

Smoke Control and Ventilation: Two factors greatly affecting ventilation operations

- Wind - Stack effect

Sprinkler system support and operations: If determined by Fire Attack Branch that pressure and volume from municipal water supply are not adequate, supply lines should be charged and a pump discharge pressure of ___ should be established

150 PSI

Sprinkler system support and operations: Loss control groups where?

Fire floor and floor below
