Tactical Vent
Even with coordinated tactical ventilation of a vent-limited fire, this occurs until water is applied to cool fire gases.
What is an increase in combustion rate?
Attached to drafting end of hard-suction hose when pumping from static water source
What is an intake strainer?
Methods of fire suppression?
What are
1. Temperature reduction
2. Fuel removal
3. Oxygen exclusion
4. Chemical flame inhibition
This hose transports water from the hydrant or static water source to the pumping apparatus
What is supply hose?
Should be arranged so a minimum of backing or maneuvering apparatus is required
What are fill and dump sites?
This disrupts the ventilation strategy, which loses control of the fire.
What is breaking windows unnecessarily or freelancing? (Will also accept unplanned ventilation.)
Has a floating collar that rises as the tank is filled.
What is a round self-supporting synthetic portable water tank?
Before entering the building or the fire area, the firefighter assigned to the nozzle should
What is open nozzle fully to ensure adequate flow? (extra points for also including checking pattern and bleeding air from hose)
This hose roll leaves only one coupling exposed
What is a Straight Roll?
When heated to its boiling point, water converts into water vapor or steam and expands this much.
What is 1,700 times its original volume?
During ventilation, gases flow from interior to exterior because the heated, less dense gases do these three things.
What is:
1. Become bouyant
2. Tend to rise
3. Move from high to low pressure areas
Protect hose from damage of dragging over sharp corners
What are hose rollers?
Daily Double!
This is indicated by fast air movement in at the bottom and smoke moving out at the top of an entry door.
The best way to load large diameter supply hose
What is a Flat Load?
Melting asphalt, smoke or fire coming from the roof, building systems sagging or leaning, spongy roof.
What are indicators of possible roof collapse?
Primary mode of heat transfer from one compartment to another in structure fire.
What is convection?
Daily Double!!
A disadvantage of this is that it can delay initial fire attack as personnel must remove tools and equipment from apparatus and place them at fire scene before the apparatus proceeds to the water source.
May transition to rollover, flashover, or a smoke explosion at any time
What is smoke?
This must be fully deployed from the hose bed before charging the line
What is preconnected attack hose?
What are smooth bore nozzles?
If vertical ventilation is ordered, the ventilation team should always do these two things.
What is:
1. check the roof before stepping on it
2. continue to check the roof ahead of them as they cross it
In an enclosed stairway, standpipe connections can be done here.
What is the fire floor?
Water is applied directly onto burning fuels until the fire in extinguished.
What is direct attack?
A higbee indicator
What are notches or grooves cut into coupling lugs to identify coupling threads starting/connection points?
This type consists of three overlapping cuts that form a triangle that may provide a better view of conditions beneath a roof.
What is a triangle cut inspection hole?
