TCFP AIRCRAFT RESCUE FIRE FIGHTER
(ARFF) PRACTICE EXAM 1 QUESTIONS
AND CORRECT ANSWERS (VERIFIED
ANSWERS) PLUS RATIONALES 2025
1. What is the primary goal of ARFF operations?
• Rescue of property
• Salvage of aircraft
• Life safety
• Fire containment
Life safety is always the top priority in ARFF operations, above all other
considerations.
2. Jet fuel is classified as which type of flammable liquid?
• Class A
• Class B
• Class B
,• Class D
Jet fuel is a flammable liquid, making it a Class B fuel hazard.
3. What is the flash point of Jet A fuel?
• Below -40°F
• 100°F
• 200°F
• Above 250°F
Jet A has a flash point around 100°F, making it less volatile than avgas.
4. What is the purpose of a twin agent unit?
• To suppress Class A fires
• To combine dry chemical and foam for rapid knockdown
• To cool down hot brakes
• To extinguish Class D fires
Twin agent systems combine dry chemical and AFFF to maximize
effectiveness on fuel fires.
5. The maximum time allowed for an ARFF vehicle to reach any point on the
airfield is:
• 3 minutes
• 3 minutes
• 5 minutes
, • 10 minutes
FAA standards require ARFF vehicles to reach any point on the runway
within 3 minutes.
6. The term "hot brake" refers to:
• A brake under hydraulic pressure
• Overheated aircraft braking systems
• A faulty hydraulic line
• A ruptured brake line
Hot brakes occur when aircraft brakes become excessively hot, often after
landing.
7. The most effective extinguishing agent for a 3D running fuel fire is:
• Water
• Dry chemical
• CO₂
• Halon
Dry chemical works quickly on running fuel (3D) fires by interrupting the
chemical reaction.
8. An ARFF vehicle’s foam proportioning system is designed to:
• Measure water tank pressure
• Ensure the correct foam concentrate ratio
• Limit agent flow
