Flammable liquid fires, such as those involving jet fuel or aviation
gasoline, require a Class B extinguisher because it is designed to
suppress flammable liquid fires.
2. What is the minimum distance that grounding and bonding cables
must be attached between the aircraft and the fuel truck during
fueling operations?
A. After fuel hose connection
B. Before any fuel transfer begins
C. After initial flow of fuel
D. Only if static is observed
Grounding and bonding must be in place before any fuel transfer to
prevent static discharge and potential ignition during fueling.
,3. A fueling technician observes a strong odor of fuel near a parked
aircraft. What is the most appropriate initial action?
A. Continue fueling until complete
B. Notify passengers of delay
C. Stop fueling and investigate the source
D. Increase airflow in the hangar

7. What is the primary hazard associated with static electricity during
fueling operations?
A. Battery drain
B. Ignition of fuel vapors
C. Slower fuel flow
D. Equipment corrosion
Static electricity can create sparks that ignite fuel vapors, presenting
a serious fire hazard during fueling.
8. Which of the following personal protective equipment (PPE) is
REQUIRED for fueling technicians?
A. Steel-toe boots only
B. Gloves only
C. Eye protection, gloves, and hearing protection
D. Respirator only
