Review Synopsis: SOP underwent major revisions to align with best practices.
General Guidelines & Response Procedures
General Guidelines:
Freelancing Elimination: Guidelines assign responding units to pre-designated positions and tasks to eliminate freelancing on the fireground.
Command Deviation Authority: An Incident Commander (Command) retains authority to deviate from tactical guidelines to address specific incident needs.
Any specific deviation must be clearly announced on the radio to inform all responding units.
Command must possess a sound cause and rationale for any deviation.
Radio Communication Reduction: Order transmissions from Command to first alarm units are minimized and become necessary only when units must take actions not in accordance with these guidelines.
Synergy with Complementary Guidelines: Written for general fireground operations in conjunction with TOG #06 and TOG #07.
TOG #06 and #07 provide a broader, generalized framework.
TOG #08 provides fireground-specific guidelines.
Referenced TOGs function synergistically as complementary resources.
Response Procedures & Hazard References:
Outlines deployment of first alarm resources with pre-assigned tactical assignments and tasks for structure fires.
Detailed hazards, considerations, and adjusted tactical assignments based on building type are referenced in:
Residential Operations
Commercial/Mercantile Operations
High Rise/Standpipe Operations
Staffing Considerations & Staffing Deviations:
Notification Requirements: Units responding with anything other than white tag personnel must notify dispatch of their staffing level when calling enroute.
Example: "E281 enroute with 2."
Example: "E481 enroute with 3 entry, 1 non-entry."
Example: "E12 enroute with 3, 1 responding in the brush."
Engines with Less Than White Tag Personnel:
1st Arriving Engine: Must initiate a constant water supply and the Incident Command System (ICS).
4th Arriving Engine: Must assume the initial role of the Rapid Intervention Team (RIT) until the backup unit arrives with a full crew.
2nd, 3rd, or 5th Arriving Engine: If staffed with a silver tag driver and white tag personnel, they assume their appropriate operational roles outlined in Section 5.
Engine Officer with Less Than Entry Personnel: Must report directly to the command post for an assignment regardless of arrival order.
Trucks or Squads with Less Than White Tag Personnel: The officer must report directly to the command post for an assignment regardless of arrival order.
Assignment Changes: Command ensures all units understand changes to their assignments.
Upgrades and Separate Responders: Any unit upgrading or responding separately from the primary dispatched unit must report directly to the command post for an assignment (applies to career units).
Only units from the same station are permitted to "upgrade" another unit to augment staffing levels.
Example: Brush 18 is available in the first due area of Station 18 performing hydrant maintenance or mercantile inspections. Engine 18 calls enroute announcing personnel; Brush 18 clearly announces they are upgrading Engine 18.
Adding Units to Assignment: Units wishing to add themselves to an assignment must switch to the appropriate tactical talk-group and contact the responding Battalion/Deputy Chief via radio with location and details.
Example: "Battalion 21 from Truck 5, we are at Wilkens and 695, permission to be added to the assignment."
Example: "Battalion 24 from Engine 18, clear of our previous call, we are at Liberty and Brenbrook, permission to be added to the assignment."
Arrival Transmissions: First-alarm suppression units report arrival and designated responsibilities via radio.
Example (Engine 16 dispatched 3rd due on firebox 7-04): "E-16 has arrived, we are assuming 3rd due."
Example (Engine 12 dispatched 5th due on firebox 54-01, E-54 and E-211 arrive on location): "E-12 has arrived, we are assuming 3rd due."
Assignment Downgrades/Cancellations: If additional information is received and no units are on location, the Chief holds ultimate authority to downgrade, slow, or cancel the assignment.
Incident Command System & Tactical Objectives
Command Responsibilities & Operations:
Command determines fireground strategy and ensures personnel safety, continuously monitoring and evaluating strategy from first arrival.
Strategic, tactical, and task outlines are defined in TOG 07.
Re-evaluation by later arriving officers: Must reassess strategy based on risk. Changes in strategy require informing all units and conducting a Personnel Accountability Report (PAR) as appropriate.
Command manages all unstaffed ICS positions (Medical, Safety, Rehab, etc.) until assigned.
Tactical PAR must be conducted per Appendix D.
Incident Duration Reminders (IDR):
Time awareness is critical for managing complex incidents and ensuring safety.
Dispatcher provides IDR updates to Command at intervals.
Example: "Command from Dispatch, 10-minute IDR."
Progress Report Requirements at Each IDR:
Incident progress (current conditions and actions)
Status of searches (Primary/Secondary)
Incident strategy (Offensive, Defensive, Transitional, Demobilizing)
Resources (additional resources needed; long-term unit commitments)
IDR progress reports cease once the fire is declared "Under Control."
Fireground Objectives (S.L.I.C.E.R.S.):
1. 360 Assessment:
Size up
Locate the fire
Isolate and control Flow Paths
2. Mode of Attack (Cooling the space from the safest location):
Offensive: Crews actively suppress fire in a forward manner inside the structure. Officers must make every effort to determine specific fire location before handlines enter immediately dangerous to life or health (IDLH) atmospheres.
Defensive: Fire suppression operations conducted from the exterior, considering exposures.
Transitional: Actions taken to suppress fire load from the exterior before transitioning to an offensive interior attack.
3. Extinguish the Fire:
Select handline or master stream based on conditions and objectives.
Advance handline along the safest, most direct route.
Handline Objectives: Protect potential victims and fire crews; confine the fire; control the fire; protect interior stairways if crews operate inside.
4. Actions of Opportunity (May occur at any time):
Rescue
Salvage
Resource Allocation & Strategy Prioritization:
Life safety is always the primary objective, though extinguishment tactics often accomplish life safety (rescue).
Command assigns resources only to the highest priority, uncompleted objectives before addressing lesser priority tasks.
Deployment Reports:
Required prior to crew entry for accountability and resource tracking (given by officer or crew member):
Point of entry and/or area of operations.
Number of personnel making entry.
Assigned task or operation.
Location or task changes (Example: "Engine 60 has knocked the fire on the first floor, heading to the second.").
Exit from structure with relative location (Example: "Engine 16 has exited Side Charlie with 3 personnel.").
Entry Examples: "Engine 19 making entry Side Alpha with 3, reporting to Division 2"; "Truck 8 making entry Side Alpha with 2 for search."
Periodical Updates to Command:
Utilizes CAN (Conditions, Actions, Needs) or L-CAN (Location, Conditions, Actions, Needs) formats.
Example: "Division 1 from Command, give me a CAN report" or "Engine 6 from Command, give me an L-CAN."
Response Example: "Command from Engine 6, we have heavy fire on Division 1, we are making an attack with an 1 3/4'' handline, we need a second line and vent the roof."
First Arriving Unit Actions
Pre-Arrival Tasks:
Review dispatch comments.
Reference Preplans or Fire Surveys.
Identify Fire Department Connection (FDC) location.
Identify situation facts: Time of incident, Location, Nature, Possible life hazards, Weather.
Identify primary water source.
Transmit intended water supply plan (Example: "Engine 16 will be forward laying from the hydrant at Wintergreen and Shadowbrook. Engine 8, pick up my hydrant.").
First Arriving Unit Officer Duties:
Brief Initial Report (BIR) Transmission:
Unit ID "arrived"
Arrival location (Side Alpha, Bravo, Charlie, Delta)
Building description (Single family, rowhome, apartment, commercial, etc.)
Fire situation description
Establish Command
Communicate with truck for best positioning
BIR Example: "Engine 16 has arrived on Side Alpha, we have a 2-story, end of the group, townhome. We have smoke showing. Captain Smith is establishing Shadowbrook Command. Truck 8, we pulled past; you have room on the Alpha side."
Request additional resources if needed.
360 Assessment & Risk Evaluation: Complete a 360 of the structure unless structure size or immediate fireground concerns make it impossible. Factors to evaluate:
Building construction and hazards.
Number of floors (above and below-grade) on each side.
Egress points and flow paths.
Rule in or rule out presence of basement or below-grade fire.
Conditions and exposures on each side.
Likely fire location.
Structure status: Occupied (in use, occupants inside, e.g., cars in driveway), Unoccupied (in use, no occupants, e.g., overnight mercantile fire), Vacant/Abandoned (not in use, boarded up).
Occupant/neighbor interface: (A) Occupants accounted for; (B) Occupants not accounted for; (C) Occupants known to be trapped.
Hazards and weather conditions.
Establish accountability level (TOG 06).
Develop incident management organization.
Ensure 2-in/2-out / RIT prior to IDLH entry following preliminary risk assessment (TOG 07 & 09).
Provide tactical objectives.
Maintain and control communications.
Situation Update Report (SUR): Transmitted separately from BIR after gathering additional 360 findings.
Announce pertinent 360 findings.
Announce presence/absence of basement and basement fire.
Announce if 360 could not be completed.
Announce mode of attack (Offensive, Defensive, Transitional).
Provide initial crew Deployment Report.
Announce deviations from TOG 08.
SUR Example: "360 has been completed, 2 stories in the front, 3 stories in the rear, with a walkout basement on the Charlie side. At this time, it does not appear we have a basement fire. I have a row of exposures on the Bravo side and nothing evident on the Charlie or Delta sides. Occupants are not accounted for at this time. We will be in an Offensive mode of fire attack. The crew from Engine 16 is stretching an 1 3/4'' attack line to Side Alpha, they will be making entry with 2 personnel for fire attack on the first floor."
Engine Company Operations
Primary Responsibility: Confine and extinguish fire by deploying a handline of appropriate length and diameter, positioned safely and effectively.
1st Arriving Engine:
Initiate constant water supply:
Forward Lay if closest water source is in response path (water source can be bypassed if within of structure and hand-jacked by driver).
If closest water source is not in response path: Initiate Split Lay (completed by next engine), instruct 2nd engine to Reverse Lay, or execute Reverse Lay with Attack Line.
If covering hydrant, advise 2nd engine (Example: "Engine 54 arrived with my own water source.").
Position apparatus for greatest tactical advantage.
Officer may assume Division Supervisor on fire floor unless Command is not established or another role is assigned.
Place primary handline in service to achieve objectives: Rapid fire attack, support search/rescue, protect stairwells/hallways/egress, exposure protection (placed between fire and potential victims).
2nd Arriving Engine:
Complete water supply for 1st engine (pump 1st engine's hydrant in hydrant areas, complete split lay, or reverse lay from 1st engine to water source).
If 1st engine covered its own hydrant:
Identify secondary water supply (coordinate with 3rd engine to avoid source competition).
Stage on secondary source with apparatus and driver; officer and crew report to Side Alpha.
Ensure adequate space for truck before committing supply lines.
Officer may assume Division Supervisor on fire floor if 1st officer is not assigned or if 1st officer declared "Limited Command."
Assist initial handline deployment, then advance a secondary/backup handline equal to or greater in diameter and flow capability.
Backup line objectives: Protect initial crew, cut off fire advancement on floor above, assist extinguishment.
Deploy line through same entry point if initial line makes no progress.
3rd Arriving Engine:
Hydrant areas: Establish own water supply and position on Side Charlie if apparatus-accessible.
Officer reports to Side Charlie, gives updated conditions report (does not assume Division Supervisor unless assigned).
Side Charlie duties:
Transmit CAN report.
Stretch handline of sufficient length to reach any interior portion (do not advance inside without coordination with Command/Division Supervisor; ensure no opposing positions).
Option to use handline on exterior fires.
Actions of opportunity: Forcible entry/obstacle removal, ladders, lighting, utilities.
4th Arriving Engine:
Driver positions away from scene without blocking other units.
Serves as Rapid Intervention Team (RIT); cannot be assigned to other groups/divisions.
Report in full turnout gear, SCBA, and proper tools.
If short-staffed, assume initial RIT role until backup unit arrives with full crew ( entry personnel).
Rapid Intervention Task Force (RITF) arrival: Establish RIT group, appoint RIT group supervisor, establish RIT branch director if incident is complex (TOG 09).
5th Arriving Engine:
Complete secondary water source.
Report to Side Charlie to back up 3rd engine (unless assigned elsewhere).
Functions as versatile 1st alarm unit: Engine support, truck support, EMS support, or "on-deck" / relief crew.
Truck & Rescue Operations
1st Arriving Truck Operations:
Positioning: Typically Side Alpha, or side deemed best for effective operations.
Inside Team (Officer and Search):
Gain access for engine company.
Perform search and rescue (start on fire floor in areas with trapped victims; VEIS; notify Command when search is complete).
Check for extension and perform overhaul.
Perform horizontal ventilation when appropriate.
Actions of opportunity: Obstacle removal and utility control.
Outside Team (Roof and Outside Vent):
Position truck for aerial operations.
Ladder Alpha and Charlie sides (give CAN report from Side Charlie if unassigned and conditions changed; advise Command if Charlie is inaccessible).
Roof duties: Roof size-up, CAN report, vertical ventilation when appropriate.
Horizontal ventilation in coordination with fire attack and Command.
Perform VEIS when appropriate.
Ladder all sides and illuminate structure.
Actions of opportunity: Obstacle removal and utility control.
Advise Command when tasks cannot be completed, or when starting VEIS/vertical ventilation (proceed after Command acknowledgement; report completion).
Radio Examples: "Command from Truck 13 Roof, going to perform vertical ventilation on the Alpha side."; "Command from Truck 5 OV, going to VEIS Side Charlie second floor." -> "Command from Truck 5 OV, VEIS complete, search was negative."
2nd Arriving Truck Operations:
Support 1st truck operations; monitor tactical talk-group to track 1st truck objectives.
Position on Side Charlie if accessible (unless directed elsewhere or another side is tactically advantageous after contacting Command).
Outside Team ladders Bravo and Delta sides.
Squad / Rescue Company / Rescue Engine Operations:
Rescue engine assumes these duties if not part of initial dispatched engines (announced by dispatch).
Support truck operations; monitor tactical talk-group.
Position apparatus near scene without interfering with engine/truck positioning.
Crew objectives: Gain access for engine, search and rescue (fire floor first, VEIS, advise Command upon completion), check extension/overhaul, ensure laddering on all sides, perform horizontal ventilation, control utilities, illuminate structure.
Advise Command when tasks cannot be completed or when initiating VEIS.
Command, Safety, and Support Roles
Chief Officers:
1st Arriving Chief Officer:
Establish Command Post with direct line-of-sight to structure (reposition vehicle, relocate command post vehicle, or relocate outside if line-of-sight is blocked).
If arriving with/before other units: Complete First Arriving Unit Actions.
If Command established prior to arrival: Perform face-to-face transfer, re-evaluate situation (360/size up), perform risk assessment, verify accountability system, verify RIT is established, re-evaluate strategy/IAP, assume Command.
Announce transfer of Command, SUR, strategy changes, and reassign initial IC (primary consideration to crew integrity).
Additional Chief Officers: Report to Command Post; assigned as Division/Group Supervisor, RIT Branch Director, or Safety.

Appendix C: Handline Selection & Placement Rules:
Minimum Flow Rates:
handline:
handline:
handline:
Tactical Rules:
Primary handline controls access and supports search/rescue by confining fire spread from halls/stairwells/egress.
Never advance a dry line into a fire area/IDLH (stretch and charge in a safe area).
Maximum lines through a single point of entry to avoid crowding (use separate entry points).
Line placement between fire and potential victims always takes precedence over attacking from unburned sides.
Consider initial line attack for mercantile, apartment, or large fire load structures.
Consider initial line on well-involved residential structures (may switch to after bulk knockdown).
Deploy line as backup if initial line fails to make progress.
Discontinue lines or transition to exposure protection once exterior master streams operate.
Deployment of line may require crews.
Establish handline or master stream for exposure protection if fire impinges on adjacent structures.
Appendix D: Tactical Personnel Accountability Report (PAR):
Definition: Controlled and initiated by Command (not a roll call PAR). Focuses rapidly on personnel in/around IDLH. Duration target is .
10-Step Sequence:
1. Command announces standby for Tactical PAR.
2. Command waits for officers/supervisors to verify personnel.
3. Officers/supervisors check location/status of assigned personnel.
4. Division/group supervisors check in with company officers under their command.
5. Command runs PAR from most hazardous to least hazardous areas.
6. Division/groups report PAR listing assigned units using their assigned designator.
7. Discrepancies between reports and Command board/binder are rectified between supervisor and Command.
8. If discrepancy persists, Command contacts company officer directly.
Verbatim Tactical PAR Transcript Example:
Command: "Command to all units on the fireground, standby for a Tactical PAR." (Waits 1-2 minutes)
Command: "Command to all units, conducting a Tactical PAR."
Command: "Division 2, are you PAR."
Engine 6: "Division 2 is PAR, 3 from E61, 3 from E6 and 2 from T15, Engine 6 Officer is Division 2."
Command: "Command copies, Division 1 are you PAR?"
Engine 15: "Division 1 is PAR, 3 from E15, 4 from E281, Engine 15 Officer is Division 1."
Command: "Command copies, Basement are you PAR?"
Engine 7: "Basement is PAR, 3 from E7, 1 from T15, Engine 7 Officer is Basement."
Command: "Command copies, Roof are you PAR?"
Truck 15: "Roof is PAR, 1 from Truck 15."
Command: "Command copies, RIT are you PAR?"
Engine 57: "RIT is PAR, Side Alpha, 4 from Engine 57, Engine 57 Officer is RIT."
Discrepancy Resolution Dialogue Examples:
Example A: Command: "Division 2 are you PAR?" -> Engine 61: "Division 2 is PAR, 3 from E61, and 2 from T15, Engine 61 Officer is Division 2." -> Command: "Division 2, I had E6 up there with you with 3." -> Engine 61: "Correction Chief, Division 2 is PAR, 3 from E61, 3 from E6 and 2 from T15."
Example B: Engine 61: "Command from Division 2, I do not have eyes on Engine 6." -> Command: "Engine 6 from Command, what is your location?" -> Engine 6: "Engine 6 is PAR, 3 heading up the stairwell to Division 2, 1 at the pump panel."
