420-01 Fire Attack Operations

The flow path is the volume between an inlet and an exhaust that allows the movement of heat and smoke from a higher-pressure area within the fire area toward lower-pressure areas accessible via doors, windows, and other openings.

This rule requires two firefighters to enter a hazardous area, and two must remain outside to ensure a quick rescue if needed.

A critical component of fire operations, ensuring personnel accountability and safety, especially in complex environments like fire buildings.

Actively fighting the fire by advancing towards it with hoses and extinguishing agents. It involves direct engagement.

Combating the fire from a safe distance, typically when the fire is too dangerous for offensive tactics.

A strategic plan developed during an incident, outlining actions and objectives for firefighters. It is continuously evaluated and adapted.

A crucial factor in fire safety, determining the risk level of a zone based on the fire's intensity.

1. Any area were risks outweigh the benefit.
2. Nobody is allowed to enter this area, regardless of PPE, due to extremely dangerous conditions. Nobody means nobody; no Fire Rescue, no Law Enforcement, no ISOs, no civilians, and no media personnel.

1. Any area with high risk.
2. Any area within the immediate perimeter of any fire or products of combustion (which include smoke and soot).

1. Any area with little risk.
2. The area not in the immediate vicinity of any fire or products of combustion.

1. Any area with no risk.
2. Any area outside of the hot and warm zone, ideally uphill and upwind.

The tactical priority for hose line placement in offensive mode, aiming to save lives and protect escape routes.

A hose line placement priority in offensive mode, focusing on protecting nearby structures from the fire.

A hose line placement priority in offensive mode, aimed at containing the fire within a defined area.

The final priority in offensive hose line placement, focusing on extinguishing the fire completely.

A common practice in fire suppression, involving using a strong water stream aimed at the ceiling to cool the room and create a more controlled environment. For effective fire extinguishment.

A hose line pre-connected to the fire engine, ready for immediate deployment. Examples include cross lays and bumper lines.

Hose packs used for longer reaches and rapid deployment, providing flexibility in fire operations.

Hose lines used for firefighter protection, typically mirroring the same size and capabilities as the main attack lines.

The operations conducted after the initial fire attack, focused on exposing hidden fires and ensuring full extinguishment.

A key tool in overhaul operations, used to detect hidden heat and identify potential reignition hazards.

A common type of insulation that can pose a significant rekindle hazard due to its tendency to trap heat. Requires careful inspection during overhaul.

The use of large-capacity water streams to control exposures in defensive mode, typically using 2½” hose lines delivering at least 200 GPM.

Special equipment used in defensive mode for safety and effectiveness. These systems can operate unattended and are ideal for protecting exposures in collapse zones.

second tender to the incident.

An individual responsible for managing water resources during incidents, ensuring efficient deployment and utilization.

A fire requiring the use of all first alarm units, triggering additional notification and resources. This signifies a serious fire requiring extra action.

A report communicated by first responders upon arrival, indicating the presence of a "Working Fire" if necessary. Its intended purpose is to trigger important actions in emergency response.

i. Additional units ii. Additional Command Staff iii. Additional Alarms iv. Florida Public Utilities (FPU) v. Light and Air vi. Tender(s)

i. Administration ii. Investigator iii. District Chief iv. Florida Power and Light (FPL)

a. Water source must be nearby. b. A hose line shall be (or be in the process of) being deployed. c. RPM’s shall be increased and deck gun aimed at the seat of the fire prior to flowing water.

i. Prior to laying supply lines and committing to a hydrant, the unit assigned to Water Supply shall ensure the hydrant is functional and the water supply is available. ii. When water supply from a hydrant is used, the Incident Commander may coordinate with the Fire Operations Officer to request increased pressure.

iii. If the attack Engine is in an area with nearby hydrants, the Driver Operator should be responsible to secure the water supply. iv. A source Engine should supply the attack Engine if the LDH hose lay is greater than 500 feet.

the Incident Commander as to the location and type of water supply.

1. Dramatically reduce heat within the flow path.
2. Improved occupant survival.
3. Create safer interior suppression conditions.

over-pressurization of the fire compartment and decease the chance of survivability.

a. Directly into the fire compartment. b. Utilize a SOLID or STRAIGHT stream without movement of the nozzle. c. Directed into the ceiling. d. For no longer than 15 seconds.

vii. Special Operations viii. Red Cross ix. CARES Team

d. The deck gun should NOT flow more than 20-30 seconds. e. Shall NOT be used when the fire location is undetermined. f. Shall NOT be used when it may negatively affect survivability of victim(s).

Notify the Incident Commander when the water tank is half full.

Advise firefighters to leave the building when the tank water is at 25%.
