Effect on stopping distance by snow/ice
3-15 times stopping distance vs dry pavement
At what speed can you outrun effective range of sublime warning devices

36,000 lbs
List examples of auxiliary braking system
- exhaust brake
- transmission output retarder
- Engine compression brake
- Electromagnetic retarder
What causes a retarder to lose effectiveness
Higher ambient temperatures
What depth of snow are automatic chains effective at
3-6”
ATC ( Automatic Traction Control) does what
Reduces engine torque and applies brakes to wheels that are spinning
What happens when differential lock is applied
both wheels forced to turn at the same speed

When do you need to have protection form falling objects at a high-rise fire
all personnel within 200 ft of the base
If building is less then 5 floors where does the wagon park reference the truck
Inside the truck
when pumping an FDC how close should the wagon position
as close as possible
Can a hard sleeve be hooked to a hydrant
ONLY if it is designed to withstand the positive pressure
How to minimize kinking when hooking to a hydrant
put a Counter Clockwise Twist in the hose
Dual Pumping
Two wagons and one strong hydrant
-Wagons are hooked together intake to intake so the second wagon gets the extra water that is not used by the first wagon
Tandem Pumping
(Standard Ops) (Relay)
used to boost pressure
Relay Pumping
Used to increase volume of water

Positioning for Wildland Structure Proctection
Position on Leeward side of Structure
How do you position for woodland fire attack?
Position in an anchor point (Natural or man-made) barrier that will prevent the fire from flanking crew
Who does the staging officer report to ?
Planning Section Chief
How much distance does a fully loaded train take to stop?
1-2 miles
How far away from train tracks do you need to keep clear
30 feet

- Quantity
- Distance
- Elevation

- decrease throttle
- open dump line
- disengage pump
What is an open relay
use of drop tanks at each pumper
whats the advantage to use of inline relay valves ?
allows pumpers the ability to join the relay without interrupting the water supply
What is the most common way to create foam
Mechanical Foam
What is Foam solution
water plus foam before its aspirated
Two types of Class B Fuels
Hydrocarbons
Polar Solvents
Hydrocarbon are what
petroleum-based; will float on water
i.e. gasoline
Polar Solvents are what
Mix with water
i.e. alcohol
4 ways foam is proportioned
- induction (educatior)
- injection
- batch mixing
- pre-mixing
How does Class A foam work
Has hydrocarbon surfactant that reduces surface tension of water
What is the Application rate
its the minimum amount of foam solutions that must be applied to a fire per min per SF
What is the shelf life of class B foam
Protein Foam 10 years
Synthetic Foam 20-25 years
How do you proportion low energy foam
use the main fire pump to provide the pressure
List portable low energy foam
- In-line foam educators
- foam nozzle educators
- Self educating master stream nozzles 350 GPM or more
what can a Jet ratio controller provide
rich foam solution to a master stream educator from 3,000 ft away.
Apparatus Mounted Low Energy
- Installed in-line educator
- Around the pump proportioner (Most common)[line from discharge to intake with educator in line, uses onboard tank]
- bypass-type balance pressure proportioner (ARFF)
- variable-flow variable-rate direct injection
High energy/CAFS
Introduces art into solution prior to discharge into hoseline
Foam Application Techniques
- Direct (Class A)
- Roll on
- Bank down
- Rain Down
traits of Durable agents
- Can last 24 hours
- can be rehydrated
