MODULE:3FIRE CONFINMENT AND

EXTINGUISHMENT

OBJECTIVESModule 3

Select and deploy the appropriate hose lines to accomplish fire confinement and extinguishment

Identify and explain the actions required to support fire confinement and extinguishment activities.

OBJECTIVESModule 3

Explain the correct procedures and select the appropriate size hose-lines for attaching to a fire department connection

Describe the procedures for deployment of a hoseline from a standpipe system

DEFINITIONSAND

PRINCIPLES

Fire Confinement

Those actions taken to confine a fire to a given area of present involvement by preventing the spread of fire into any uninvolved area.

Fire Extinguishment

Those actions taken following fire confinement to extinguish a fire by removing the fuel, air supply, or, most commonly, the heat.

Principles of fire confinement and extinguishment

• Keep fire from extending into unburned area

• When fire confinement has been accomplished, fire extinguishment is the next tactical operation

FIRE CONFINEMENTTACTICS

Confinement for Specific Purpose

• Search or rescue

• Awaiting additional resources

• Save portion of structure

• Prevent fire extension

Sizeup for Confinement

• Location and extent of fire

• Building construction classification and occupancy

• Fire flow requirements

• Lead time required

• Fixed suppression equipment

• Personnel available

• Coordination required

Selection of Hoseline and Nozzle for Fire Confinement

• Size of hoseline

• Length of hoseline

• Type and size of nozzle

Positioning of Hoseline to Support Fire Confinement

• Support search and/or rescue

• Confine fire to prevent further destruction

• Coordinate with ventilation

Fire Confinement Tactical Action Plan

• Hoseline(s) and nozzle(s)

• Hoseline placement(s)

• Support required

• Personnel and equipment required

• Coordination required

• Safety concerns

• Task assignment(s) for crews

FIREEXTINGUISHMENT

TACTICS

Fire Extinguishment--Purpose

To bring burning materials below their ignition temperature to stop flame production

Sizeup for Extinguishment

• Location and extent of fire

• Risk vs benefit

• Access and egress

• Classification of building construction and occupancy

Nozzle Selection

• Flow must exceed heat being produced

• If unsure, select largest flow

• Select appropriate nozzle pattern

Hoseline Selection

• Size of hoseline to match nozzle

• Long enough to reach seat of fire plus 50 feet

Positioning of Hoseline

• Areas of access and egress

• Attack from unburned side

• Select position for backup line and communicate to crew

Coordinate fire extinguishment with other Tactical Assignments

• Ventilation

• Entry

• Laddering

• Lighting

Safety

• Has Safety Officer been designated?

• Risk vs benefit

• Accountability system

• Has IC been informed of location of extinguishment team?

Fire Extinguishment TacticalAction Plan

• Hoseline(s) and nozzle(s)

• Hoseline placements(s)

• Required support

• Required personnel and equipment

• Required coordination

• Safety concerns

• Task assignment(s)

SUPPORTING AND USINGFIXED FIRE PROTECTION

EQUIPMENT

Automatic Sprinkler

• System of piping, valves, and water discharge heads

• Highly effective in confining or extinguishing fires

Standpipe System

• System of piping and valves to provide water supply at fire floor

• Provide 2-1/2” connection with 500 gpm at 65 psi

INSERT SLIDE #3-48

Pre-incident Planning

• Normal water supply for system

• Fire pump

• Control valves

• Fire department connection

Connecting to a FireDepartment Connection

• One of first alarm companies must connect to system

• Check for debris in connections

• Connection may have only one water supply intake

Pumping into automatic sprinkler systems

• Once pressure from a fire department pump exceeds normal water pressure, the normal supply valve will close.

• Pump operator should observe flow meters, can be a clue as to how many heads hav opened

Connecting Attack Line toStandpipe Connection

• Standpipe kit

• Stretch hose up stairs past fire floor

• Use Wye for smaller attack lines

• Look for fire pump activation (pressure surge)

• Coordinate pressure with pump operator

Insert Slide #54 Module 3

Coordination

CO given a tactical assignment to confine and/or extinguish a fire must coordinate their efforts with all other tactical assignments

Coordinate with Other Tactical Assignments

• Other hoselines

• Water supply

• Ventilation

• Laddering

• Air supply

• Other support functions

Safety Considerations

• Can risks be managed?

• Coordination

• Keep IC informed

• Be aware of time and structural conditions

• You are the safety officer for your crew

Supporting and Using Fixed FireProtection Tactical Action Plan

• Supply line size

• Required personnel and equipment

• Connect to system at right pressure

• Connect standpipe hose

• Required support

• Required coordination

• Safety concerns

• Task assignments(s)
