Primary Boundary Characteristics
ANY physical boundary can be a primary fire boundary (FB)
Generally set at fire zone bulkheads or watertight subdivisions.
Minimum fume-tight for Main Space Fire.
All six sides of affected space: Bulkheads, overhead and deck closest to the fire.
Primary emphasis must be on vertical boundary
It should be the repair party leader’s decision to man fire boundaries with charged hoses.
Actions taken by primary boundarymen
Remove ALL combustibles away from boundary
Cool
To prevent rapid steam build-up and increased risk of steam burns, the firefighter should use initial bursts of water which may be as short as 1-2 seconds
Close All accesses, maintain Zebra
May be manned by a single person with a 1 1/2 inch hose
SCBA worn by boundarymen as required
Secondary Boundary Characteristics
Next bulkhead, overhead and deck outside the primary boundary.
Manned when fire spreads past primary boundaries
Smoke Control Zone
Area between primary and secondary smoke boundaries
when the access to the fire space is opened by the attack team, smoke will be trapped in the smoke control zone.
Breathing device required here
OSL Characteristics & Responsibilities
In charge of firefighting at the scene
Normally located outside the primary fire boundary
Communicates with the Repair Party Leader
Sizes up the fire
Determines method of attack
Determines protective clothing requirements
Determines if active desmoking is required
Monitors hose team reliefs
Directs electrical isolation
Hose Handling Requirements
One person can operate an 11/2 inch hose in initial attack
Sustained operation requires a minimum of 2 hose handlers in addition to the nozzleman (requirements increase based on hose length and number of turns)
Two people can operate a 21/2 inch hose in initial attack
Sustained operation requires a minimum of 4 hose handlers in addition to the nozzleman (requirements increase based on hose length and number of turns)
Firefighting Patterns: Straight Stream
Used in direct attack.
Also good to penetrate and break up burned Class (A) material for overhaul. (100 feet at 100PSI)
Firefighting Patterns: Narrow Angle
(30 Degrees) General firefighting pattern. Good for providing a “push” to flame fronts. (50 feet at 100 PSI)
Firefighting Patterns: Medium Angle Fog
Medium Angle fog / (60 Degrees) Used to interrupt the thermal layer in the roll over stage of a fire
Firefighting Patterns: Wide Angle Fog
Wide angle fog / (90 Degrees) Good heat absorption, used for personnel protection. (5-10 feet at 100 PSI)
F/F Attack Techniques
Direct Attack
Fog Attack
Indirect Attack
Venting Options
Direct Attack
Direct Attack - Preferred method
Short bursts (several seconds) of water with a narrow angle fog or straight stream nozzle pattern onto the seat of the fire.
Fog Attack
Fog Attack (to gain control of fire)
Used when:
–Overhead gases are burning (Rollover).
–Seat of fire is obstructed.
–Multiple seats of fire present.
–Delay or prevent flashover during growth stage.
Indirect Attack
–When heat or other conditions deny access to space.
–May improve condition to permit reentry for direct attack.
–To cool space, apply water fog into space from a cracked open access or hole cut in the deck.
–Follow immediately with direct attack.
Venting (Attack Method)
–Additional option to consider when topside or in large area that opens to weather.
Cut hole in access above fire.
–Minimum of 12in x 12in
–Must be wearing full Firefighting Ensemble including SCBA.
Active Desmoking authority
OSL requests
RPL approves
When should you actively desmoke?
–If the initial attack is unsuccessful.
–If likely that the fire attack will go on for an extended period of time.
If smoke or heat is spreading to spaces beyond the fire space impeding the attack on the fire.
What is the goal of desmoking?
The goal in desmoking is to replace 95% of the smoke-laden air with fresh air. This will require approximately 4 complete space volume changes in a compartment.

flashover
Simultaneous ignition of all contents of the compartment.
Normally occurs when the upper gas layer reaches 11000F.
