Aircraft Rescue and Fire Fighting Flashcards
what is the ARFF index based on
the length of the most demanding aircraft serving the airport and the number of average daily departures. the single most important indicator of the potential size of an aircraft emergency is the largest passenger aircraft serving the airport
what are the indexes
A: less than 90 ft
B: at least 90ft, less than 126
C: at least 126, less than 159
D: at least 159, less than 200
E: at least 200
a holder of a class III airport operating certificate may comply with this section by providing a level of safety comparable to index A that is approved by the administrator. Such alternate compliance must be described in the ACM and must include:
- pre arranged firefighting and emergency medical response procedures, including agreements with responding services
- means for alerting firefighting and emergency medical personnel
- type of rescue and firefighting equipment to be provided
- training of responding firefighting and emergency medical personnel on airport familiarization and communications
what are the primary aircraft fire extinguishing agents to be used on airports
Aqueous Film Forming Foam (AFFF), Fluoroprotein Foam (FP), Film Forming Fluoroprotein (FFFP), and Protein Foam
how does an extinguishing agent work
by smothering the fire to prevent oxygen from mixing with the hydrocarbons, suppressing the release of fuel vapors, separating the combustible materials; or lowering the temperature of the fire through a cooling effect
smothering, suppressing, separating combustibles, lowering temp
what is the most common extinguishing agent
AFFF: it can seal and suppress the release of fuel vapors, provide a cooling effect, separate combustible materials, and resists breakdown from other chemical agents
why are dry chems (potassium bicarbonate, and potassium chloride) used?
they “knock down” the fire. they smother a fire by replacing oxygen. once the chemicals dissipate to opportunity for flashback may occur. Foam is a needed backup on large fires
What is an effective fire suppression around engines?
halon 1211, it has been discontinued because it depletes the ozone
what is an acceptable alternative to halon 1211
Halotron 1: distersed as a liquid it turns into a gas at the fire, and robs oxygen. it is considered a clean agent
what is a clean agent
something that does not leave residue when it is sprayed, favored for engine and break fires, and used around flight instruments or computers
When is ARFF required
15 min on either side of the takeoff or landing of an air carrier aircraft
how long does ARFF have to respond
one vehicle within 3 min, the rest by 4 min after an incident/accident
Index A must carry….
500lbs sodium-based dry chem, halon 1211, or clean agent, OR
450lbs of potassium-based dry chemical and water with a commensurate quantity of AFFF to total 100 gal for simultaneous dry chem and AFFF application
Index B must carry…
one vehicle carrying 500lbs of sodium based dry chem, halon 1211, or clean agent and 1,500 gal of water and the commensurate quantity of AFFF for foam production
OR
two vehicles. one with the requirements of A, with another carrying an amount of water and the commensurate quantity of AFFF so the total quantity of water for foam production carried by boeth vehicles is at least 1,500 gal of water
Index C must carry…
three vehicles. one carrying the requirements for A, and two additional carrying an amount of water and the quantity of AFFF so the quantity of water for foam production carried by all three vehicles (at least 3,000 gal)
OR
two vehicles. One carrying requirements for index A, and one additional carrying the amount of water and the quantity of AFFF so the total quantity of water for foam production is at least 3,000 gal
