ARFF study guide
Aircraft Rescue Fire Fighting Study Guide
ARFF CRASH TEST
1. Key To Remember when inspecting ARFF Apparatus: be systematic
2. Three common requirements when driving ARFF: Federal State laws, Fire Dept. Laws, NFPA Requirements.
3. Reasons for preventative maintenance: Ensures reliability, lessens out of service time, lessons cost of repairs.
4. CTIS is used when: apparatus is moving or stationary.
5. How long for handline nozzle test 30 sec.
6. The purpose for the manifold on the center console is to: regulate air pressure of SCBA mask.
7. When performing turret ground pattern test disregard: ½ inch
8. ARFF test record for overall performance: Yearly
9. To accruatly perform the foam-solution concentration test, you must first obtain refraction readings from: water, foam solution, foam concentrate.
10. Color of hold positions: Yellow
11. Three things on you need to know on all foam tests: Pressure flow, systems operational, piping flushed
12. Periodic Basis: 4-12 months
13. Fuel oil milage be updated: as determined by the authority having jurisdiction.
14. Two guidelines for numbering a runway: Letters L, R, numbered by compass guidelines
15. When planning an ARFF Response: identify height, weight & width of apparatus
16. Three steps to take when performing a confined space turnaround: Do not cross lines, use both mirrors, visual contact with spotter.
17. Three advantages of balance pressure foam prop system: no water intake pressure, water foam simultaneously charge, various percentages of foam can be discharged from multiple outlets.
18. Serpinine exercise: drive forward and reverse between markers.
19. Civilian aviation fuel has lower flash point than jet fuel, hypergolic presents a hazard
20. 2 defensive driving exercises: straight line driving, lane change
21. Extinguish base of the fire: use extendable turret
22. Ramp temp is: 25-45 degrees hotter
23. Substance that spontaneous ignites in contact with others- Hypergolic
24. Low energy foam proportioning system: direct injection, balanced pressure
25. Highest flashpoint, slowest flame spread: Kerosene
26. Extinguish a peripheral fire: Handline
27. Resupply foam from: overhead gravity, 5 gallon, transfer from tanker.\
28. Extinguish class d fires: dry powder
29. Onboard water supply lasts: 1-3 min
30. Postion on: nose or tail
31. non air aspirating provide better reach and penetration
Daily Checks - Pump drive control, pumping instruments, agent tanks, winterization system, fuel tank, fire suppression system, Battery, wheels/Tires
Weekly Checks - Pump Intake strainers, pump gearbox, packing glands, pump pressure control device, foam transfer pump.
Incab checks Mirrors, parking brake steering wheel, sterring column, equipment, seats/seatbelt, brakes
Control Tower Lights Steady Green ( ok to cross), Steady Red (Stop), Flashing Red (Clear runway), Flashing White (Return to starting point), Alternating Green/Red (Use extreme Cautiion)
Downwind- landing approach,
Base Leg Before final Approach
Final Approach Landing
Left Turn: Activate turn signal, check sideview mirror, move into left lane, check side road clear, make left turn
Sight on control Max distance in which you can see an obstruction and safely stop
Extinguishing Agents- A Combustibles, B Fuels, C Electrical, D Metals
Auxillary p Dry Chem, Dry Powder
212 degrees water boils
Fuel for aircraft AvGas, gas & kerosene, kerosence
Kerosene Flashpoint: 100-115, Flame Spread: 100 ft per min
Blends FP: -10 , FS 700 to 800 ft per min
AvGas FP 49, FS 700 to 800 ft per min
Aircraft fuel spills should be blanked with foam more than 10 ft in any direction
50 sq ft in area
1. The Apparatus may have a steering problem if the steering wheel can be rotated more than 10 degrees
2. To determine if the air filter needs to be changed check the restriction indicator
3. Foam Transfer pump should be operated for 10 seconds
4. CTIS is used for adjust tire pressure
5. Prior to performing the ground pattern test make sure tank is full , proportioner is set for normal operations, full of foam concentrate
6. Steps for turret ground pattern test Discharge 30 secs, place markers, disregard ½ inch, plot graph paper, measure distance.
7. Handline nozzle test analyzes foam pattern from nozzle
8. Expansion ratio if lower than 70 degrees add 0.1 unit
9. Drainage time subtract 0.1 unit
10. Periodic inspections Flush pump tank, cooling system hoses, power saws
11. Test that uses a refractometer Foam-solution-concentration test
12. 3 reasons for inspection reports insurance, data refrence, replacement
1. Dry chemicals are compatible with AFFFs
2. Dry chem. Only used on class a , b , c
3. halogenated agents do not work on self-oxidizing materials
4. to find the nozzle application rate nozzle gpm by square foot of fire
5. Primary uses of water in ARFF cooling, forcing fuel away, extinguishing class A
6. Dry powders most effective on combustible metals
7. Auxillary agents must be compatible with primary, must be used on a specific class of fire
8. foams most commonly used to extinguish fuels low expansion
9. 3 ways foam works to extinguish separate, cools, smothers
10. Two laws that apply to water law of specific heat, law of latent heat
11. three characterisitics of fuel spills more than 10 ft in any direction, continuous, 50 sq feet in area
12. Using 3 % solution you must mix 3 gals of foam with 97 gal of water
13. high-expansion foam proportioning air injected into foam solution
14. 3 low energy foam proportioning systems batch mixing, installed inline eductor, balanced pressure
15. Getting water from static source drafting
16. Roof turret discharges 500-1500 gpm
17. It is best to discharge from uphill
18. Control phase of exterior- Insulate & isolate occupied portions of aircraft
19. Arff should always be positioned upwind
20. distance extinguishing agents projected reach
21. aspirated nozzles produce- greatest expansion of foam
1. When driving ARFF do not begin in high gear
2. FD should have ops procedures for Speeds. Crossing intersections, use of emergency lights
3. Painted X on runway closed to aircraft and vehicles
4. ILS Instrument landing system, yellow ladder marking, no vehicle/aircraft allowed
5. When traveling on an airfield follow airfield jurisdiction
6. When driving downgrade RPM should read below redline
7. When driving through a restricted horizontal/vertical obstacles Judge how much space is nessecary to clear both horizontal/vertical obstructions
