Fire Stream Mangmt Flashcards
Five tactical reasons for hose line
Size, placement, speed, mobility, and supply
When making a decision on what size stream to apply…
Select the size required based upon current and anticipated fire conditions as well as type of occupancy
2 1/2 maybe necessary on multi family due to
Fire extended to hallway, multiple units, or a chance of wind driven
Booster line attacks
Small fire outside buildings, trash fire, auto fire, grass or brush fire
Initial attack line for working commercial fire?
2 1/2
Rule of thumb estimating required flow on the fireground
Square footage of area involved (L x W)/3
The 1st line is placed between
The fire and any persons endangered
When no life is endangered, the first line is placed between?
The fire and the most severe exposure
Primary responsibility of 2 person backup line equal to or greater than attack line?
Protect above, below, and behind fire attack line
Backup line should only be put in use
If attack line becomes overwhelmed by the fire or experience a catastrophic event such as structural collapse or flashover
In cases of confirmed rescue situations, efforts should be made to
Confine instead of extinguish
What is a critical component of supporting rescue activities and confinement
Protecting avenues of egress for civilians and FF
Defensive ops are accomplished with ____ that require a large water supply and are difficult to move
Appliances
Offensive attacks are accomplished with ____ that are in place quickly and are very mobile in operation
Hand lines
Consider these 3 factors before placing hose line
Size, speed, mobility
___ ___ tips provide more penetration, reach, and striking power
Smooth bore tips
___ will not push smoke or fire l, have steam production, and less nozzle reaction
Smooth bore tips 1 3/4 160gpm 7/8
185 gpm 15/16
2 1/2 260gpm 1 1/8, 330 1 1/4
More gross gear absorption and steam expansion, less reach. Air entrainment within the stream May push fire gases when the nozzle widens
Fog nozzle 1 3/4 150gpm, 2 1/2 250 gpm
It is the responsibility of each ___ ___ to provide for an uninterrupted, adequate water supply
Engine company
Success of the first hose line depends upon all engine companies…
Assisting in establishment of a reliable water supply
The ___ ___ is expected to provide the initial water supply whenever any smoke or fire is showing
First arriving engine
Lay in lines over 300’ May require —
—- to take over the hydrants supplement water supply pressure
Additional engines
Initial water supply can be accomplished by
Forward lay, reverse lay, connecting to hydrant directly, assigning specific engine on alarm to supply
Residential occupancy no smoke or flame showing
First arriving can go to address and have next due standby hydrant
