    Characteristics of First Generation High-rises

    First Generation high-rises, constructed between the 1860s and 1920s, utilized heavy load-bearing exterior walls made of brick or stone. They often featured cast iron facades but had vulnerable cast iron columns and wrought iron beams. These buildings also had unprotected vertical openings like stairwells, elevators, and light wells, posing significant fire safety risks.

    Study Notes

    Medical Group Operations

    • If no victims, assist the Lobby Control Group. Bring all EMS equipment to the lobby wearing full PPE and SCBA. Prepare for victim treatment or assignment to the Lobby Control Group.
    • First EMS supervisor reports to the IC and establishes the Medical Group/Branch. Manages EMS aspects of victim care. Wears full PPE and SCBA. Brings triage tags, EMS Supervisor drug bag, Lucas device, and a separate ground-level triage and treatment area.
    • First arriving battalion chief takes fixed command. Command post location is flexible, but an exterior location is preferable. Lobby command allows for direct communication with crews and building engineers, potentially improving access to in-house communication systems. A disadvantage of a lobby command post is the I/C's limited view of building exterior progress.
    • DVRS is a repeater system on SO-2 and BC vehicles boosting radio signals to nearby towers. Modes: Off, Local Mode (line-of-sight), and System Mode (signal boosting). Four channels: CFD DVRS, 7TAC51 DVRS, 7MED65, and 7MED66. CFD DVRS and 7TAC51 DVRS are in zones 1-8 (e.g., B1 CFD DVRS). Two DVRS units on same frequency within two miles: one becomes inactive. For large incidents, use 7TAC51. DVRS is helpful in high-rise buildings where radio signals struggle.
    • Resource Floor: Two floors below the fire floor. All crews exiting elevators go to the resource floor. Hub of operations above the lobby during a high-rise fire. Resource Group operates here. Stores extra equipment (SCBA bottles, hose packs, standpipe kits, hand tools, lights, electric cords, electric fans, search ropes, and RIT packs). Interior crews stage here. Operations Chief may be here, moving between the resource floor and the fire floor. Rehab for firefighters is managed by the EMS Supervisor, with one medic crew assigned. Casualty Collection Point (CCP) is set up on the resource floor. One medic crew is assigned to the CCP. The USE Group brings victims to the CCP. EMS triage starts at CCP. Resource Group Supervisor keeps a unit activity log (ICS 214).
    • Floor Below the Fire: Fire Attack Group operates here. Engine companies stand-by. Ladder companies search, find the best stairwell for attack, and use ropes and TICs. Remove victims to the CCP. Engine companies are informed of the best hose stretch location once the fire is located. Engine companies can relocate to other stairwells. The ladder company designates the Attack and Evacuation stairwells and clears above the attack entry point. Civilians need to be removed from the attack stairwell as it's a vent point. The USE group uses the Evacuation stairwell for removing victims and searches. The ladder company and an engine company member recon the floor below for additional stairwells concurrently with the ladder search.
    • Fire Floor and Floors Above: Life safety priority. Hose teams search for victims during advancement and extinguishment. Ladder personnel can temporarily leave the hose line and search for victims. Victims, if found, are removed to the CCP. Rescue operation pauses hose advancement. The USE group (first rescue, second ladder) searches floors above the fire floor using the evacuation stairwell. The ladder officer supervises. Dynamic searching is key. Hose teams check stairwells while USE personnel move up levels. Cleared floors allow group movement to top floors, elevators, and other remaining viable areas. Victims removed to CCP. "Protect in place" strategy follows IC instructions. USE Group supervisor reports conditions to the IC. The group can be reassigned once the IC declares the areas above the fire floor clear.

    Fire Attack Group Positions

    • Fire Attack Group Supervisor: Designated by the IC. Assigns hose team positions. Communicates with the IC. Monitors conditions and crews during attack.
    • Nozzle Firefighter: Carries the hose pack up, unpacks, and prepares the stretch. Stretches the nozzle half of the pack and operates the nozzle on the fire floor.
    • Back-up Firefighter: Follows the hose line removing kinks, pushes hose outward, moves hose from the stairwell to the fire area, and absorbs nozzle reaction.
    • Door Firefighter 1: Assists with removing hose kinks, positions on the landing, moves hose between floors, and travels between the floor below and the fire floor moving hose.
    • Door Firefighter 2: Assists with removing hose kinks, positions on the fire floor landing, opens and chocks the door for the hose advance, and moves hose from the fire floor stairwell into the fire area. (Usually a ladder company firefighter).
    • Control Firefighter: Positions at the standpipe outlet, acts as the remote pump operator, operates the hose outlet, and flakes out remaining hose on the floor below.

    Hose Pressure

    • 150' hose stretch (50' 2 1/2" + 100' 2") with a 1 1/16" standpipe requires 90 PSI at flow.
    • 200' hose stretch (100' 2 1/2" + 100' 2") with a 1 1/16" standpipe requires 95 PSI at flow.
    • 200' hose stretch (50' 2 1/2" + 150' 2") with a 1 1/16" standpipe requires 105 PSI at flow.
    • A 50' section of 2 1/2" hose increases friction loss by 5 PSI; a 50' section of 2" hose increases friction loss by 15 PSI.

    Additional Information (Indy Stack Tips)

    • 1 1/8" Indy Stack tip: 266 GPM at 50 PSI nozzle pressure.
    • 1 1/4" Indy Stack tip: 328 GPM at 50 PSI nozzle pressure.
    • These tips can be used with a 2 1/2" nozzle and 2 1/2" hose. Carried in the standpipe bag.

    Stairwell Designs

    • Stairwell Types: Firefighters may encounter return stairs, scissor stairs, and access stairs in high-rise buildings.
    • Stairwell Labeling: Stairwells must be labeled (e.g., roof access, basement access).
    • Floor Numbering: Floor numbers should be displayed on every floor landing.

    Fire Control Room

    • Fire Control Room: Central hub for the building's fire protection system.
    • Complexity: From a large room to a single control panel at the building's entrance.
    • Panels: Full Control Annunciator Panel, Remote Fire Panel, Elevator Control Panel, Smoke Control Panel, Building Communication Systems.
    • Functionality: Access to specific fire alarm locations, silencing alarms, assessing system status, making announcements, and communicating with designated fire phones.

    Jockey Pumps

    • Jockey pumps maintain standpipe pressure.
    • Pressure change calculations depend on building height and date of construction.
    • Small pressure drops trigger jockey pumps; large drops trigger fire pumps.
    • Jockey pumps regulate, not move, water.

    Fire Pump Room

    • Pump Room Overview: The "heart" of a building's fire protection system; may be located in basement, near the FDC, or designated pump room. Connected to domestic water system, delivering water under pressure to the fire protection system. Can be powered by electric/diesel motors. Contains fire pumps (multi-zone systems for larger buildings) and pump controls.
    • Multi-Zone Systems: Multiple fire pumps may serve different zones. Examples include the High Zone pump (3-stage, 360 PSI, floors 19-37) and the Low Zone pump (single-stage, 240 PSI, basement to floor 18) in the Huntington Center.

    Standpipe Systems

    • Standpipe Classifications: Three classes of standpipe systems exist:
    • Class 1: Fire Department Use Only. 2 1/2" outlets in stairwells.
    • Class 2: Civilian or Occupant Use. 1 1/2" outlets with 100' of attached hose. Located in hallway cabinets. Limited to 100 GPM flow. Hose often removed due to poor maintenance.
    • Class 3: Combination of Civilian and Fire Department Use. 2 1/2" and 1 1/2" outlets in hallway cabinets. May have hose; if not, it's already removed.

    Additional Hose Line Information

    • Single room fire: 1 ¾” hose line
    • More than 3 rooms on fire: 2 1 ¾” hose lines or 1 2” hose line
    • One or more floors of fire: 2 ½” hose line
    • Commercial structure: consider 2” or 2 ½” hose line
    • Defensive operations: consider master streams
