    Study Notes

    General Procedures

    • A clean work area is essential for a safer and more efficient operation in aircraft ground servicing.
    • High standards of cleanliness must be maintained to prevent the accumulation of oil, hydraulic fluids, grease, or fuel.
    • Personnel should not be subjected to increased risk when catching servicing fluids.

    Aircraft Fluids and Fuels

    • The servicing of aircraft jet fuels, hydraulic fluids, and lubricants presents a potential fire or explosion hazard.
    • Flammable mixtures can be formed by the vapors from JP-4 fuel, or from a spray or mist from a pressurized leak.
    • The flash point temperature of JP-4 fuel is -10°F, and its flammability limits are 1.3% to 7.0% by volume.
    • JP-8 fuel has a higher flash point and is relatively safer to use, with a flash point of +100°F.
    • Special care is required for JP-5 and JP-8 fuels, as they can be used as a heat sink in some aircraft.

    Refueling

    • Pressurized refueling operations present a potential hazard for pressure leaks in equipment, pipes, and hoses.
    • Ignition sources must be eliminated to prevent fires, including metal tools being dropped on concrete, sparks generated when grounding or bonding equipment, static electricity, and hot surfaces.
    • JP-4 fuel vapors can be ignited by a very small energy spark, while JP-5 and JP-8 fuels require direct contact with an ignition source to ignite.

    Hot Surfaces

    • Hot surfaces are a common ignition source during refueling operations, including hot brakes, bleed air ducts, hot engines, and APU surfaces.
    • Any heated metal object that glows is an ignition source, and fire-fighting equipment must be immediately available.

    Servicing Supervisor

    • The servicing supervisor is responsible for ensuring that all safety precautions and technical order requirements are taken during fuel servicing operations.
    • The supervisor must demonstrate a thorough knowledge of all equipment and systems involved in the servicing operations and be qualified/certified in accordance with command directives.

    Fuel Servicing Safety Zone (FSSZ)

    • The FSSZ is the area within 50 feet of a pressurized fuel carrying servicing component, and 25 feet around aircraft fuel vent outlets.
    • Active ignition sources must be removed from the FSSZ during fuel movement.
    • The FSSZ is established and maintained during pressurization and movement of fuel.

    The Aircraft Being Serviced

    • Non-essential aircraft electrical systems should not be activated during servicing operations unless absolutely required.
    • Aircrew members may operate UHF/VHF cockpit radios during servicing.

    Adjacent Aircraft

    • Aircraft parked in the FSSZ shall not be involved in engine starts or engine trim operations, radiating electromagnetic energy, or using NDI or welding equipment.
    • Maintenance, including pre/postflight inspections, may be performed on adjacent aircraft, but no spilled flammable liquids should be present.

    Servicing Constraints

    • Only personnel required for the operation should remain in the FSSZ during servicing.
    • Smoking is not allowed within 50 feet of any aircraft or servicing operation.
    • Aircraft radar and HF radios should not be operated in the transmit mode within 300 feet of servicing operations.

    Additional Safety Precautions

    • Servicing operations should not begin or continue during certain conditions, such as lightning storms, high winds, fires in the vicinity, or In-Flight Emergencies (IFE).

    • Personnel should not wear footwear with exposed spark-producing nails or metal plates on the walking surfaces.

    • Certain types of clothing should not be worn during fuel servicing operations, and matches or lighters should not be handled or removed from pockets.

    • Laptop computers, pagers, cell phones, and other devices can be operated in the FSSZ, but battery changes or charging operations are not allowed.### Defects and Fire Protection

    • Defects in aircraft servicing operations include defective emergency shutoff switch, shift linkage or gear shift indicator, tank vent valves, air pressure below 90 psi, engine backfires, fuel filter pressure exceeding maximum authorized differential pressure, deadman control valve, and nozzle.

    Fire Protection

    • Fire protection is essential during aircraft servicing operations, and personnel involved must be trained in the operation of fire extinguishers and installed fire suppression equipment systems.
    • In the event of a fire or fuel leak, servicing personnel are the first line of defense in protecting Air Force assets until the fire department arrives.
    • Notification of the fire department is critical, and available fire extinguishers or other equipment must be used until they arrive.

    Fire Extinguishers

    • The 150-pound, Halon 1211 fire extinguisher is the primary flight line fire extinguisher.
    • Fire extinguisher requirements are outlined in applicable paragraphs of this technical order and are summarized in Table 3-1.

    Installed Fire Suppression Systems and Vehicle Standby

    • Certain aircraft servicing operations require a greater level of fire protection awareness and standby posturing, such as hot refueling operations, which require modular or installed fire suppression equipment employing AFFF.
    • When such systems are not available, fire protection is provided by standby fire fighting vehicles and crews.

    Fire Department Standby Requirements

    • Table 3-1 lists various fire protection requirements for Aircraft Rescue and Fire Fighting (ARFF) vehicles.
    • During emergency situations, the fire chief or SFO directs standby vehicles to emergencies, and ARFF vehicles are pre-positioned along the runway when an emergency landing is anticipated.

    Fire Protection Policy

    • Concurrent Servicing Operations (CSO) during Combat Sortie Generation may continue fuel servicing until the present CSO is completed, but no fuel servicing portion of a new CSO may begin unless authorized by the wing commander (or senior local operational commander) until the ARFF vehicle has returned to a standby posture.
    • Two 150-pound Halon 1211 extinguishers must be located on each side of the aircraft, and servicing personnel must be trained in their use.
    • Maintenance, fuel servicing, and aircrew personnel must exercise extra vigilance during this time period.
    • When the fire chief releases the ARFF vehicles from the emergency scene, they will reservice as necessary and return immediately to a standby posture.

    Ceasing Operations

    • Certain operations must cease during emergency situations, including all aircraft hot refueling operations, concurrent fuel servicing of aircraft with passengers onboard, fuel servicing of medical evacuation flights with passengers/patients onboard, defueling when an aircraft has a fuel leak, is damaged from fire or impact, defueling into open containers or drums, or defueling where safe distance criteria cannot be met or static grounding points are not available.

    Fire Chief Determination

    • The fire chief or SFO is the primary individual for determining standby posturing requirements and ARFF vehicle standby locations for various aircraft operations.
    • The fire chief's goal is to not take away from other critical firefighter duties while still maintaining a heightened state of alert for aircraft involved in the listed operations.

    Fire Protection Equipment Requirements

    • Table 3-1 summarizes fire protection equipment requirements for various types of operations, including concurrent fuel servicing, aircraft outside of hangar or shelter, alert aircraft, and cargo aircraft with nuclear weapons aboard.

    General Procedures

    • A clean work area is essential for a safer and more efficient operation in aircraft ground servicing.
    • High standards of cleanliness must be maintained to prevent the accumulation of oil, hydraulic fluids, grease, or fuel.
    • Personnel should not be subjected to increased risk when catching servicing fluids.

    Aircraft Fluids and Fuels

    • The servicing of aircraft jet fuels, hydraulic fluids, and lubricants presents a potential fire or explosion hazard.
    • Flammable mixtures can be formed by the vapors from JP-4 fuel, or from a spray or mist from a pressurized leak.
    • The flash point temperature of JP-4 fuel is -10°F, and its flammability limits are 1.3% to 7.0% by volume.
    • JP-8 fuel has a higher flash point and is relatively safer to use, with a flash point of +100°F.
    • Special care is required for JP-5 and JP-8 fuels, as they can be used as a heat sink in some aircraft.

    Refueling

    • Pressurized refueling operations present a potential hazard for pressure leaks in equipment, pipes, and hoses.
    • Ignition sources must be eliminated to prevent fires, including metal tools being dropped on concrete, sparks generated when grounding or bonding equipment, static electricity, and hot surfaces.
    • JP-4 fuel vapors can be ignited by a very small energy spark, while JP-5 and JP-8 fuels require direct contact with an ignition source to ignite.

    Hot Surfaces

    • Hot surfaces are a common ignition source during refueling operations, including hot brakes, bleed air ducts, hot engines, and APU surfaces.
    • Any heated metal object that glows is an ignition source, and fire-fighting equipment must be immediately available.

    Servicing Supervisor

    • The servicing supervisor is responsible for ensuring that all safety precautions and technical order requirements are taken during fuel servicing operations.
    • The supervisor must demonstrate a thorough knowledge of all equipment and systems involved in the servicing operations and be qualified/certified in accordance with command directives.

    Fuel Servicing Safety Zone (FSSZ)

    • The FSSZ is the area within 50 feet of a pressurized fuel carrying servicing component, and 25 feet around aircraft fuel vent outlets.
    • Active ignition sources must be removed from the FSSZ during fuel movement.
    • The FSSZ is established and maintained during pressurization and movement of fuel.

    The Aircraft Being Serviced

    • Non-essential aircraft electrical systems should not be activated during servicing operations unless absolutely required.
    • Aircrew members may operate UHF/VHF cockpit radios during servicing.

    Adjacent Aircraft

    • Aircraft parked in the FSSZ shall not be involved in engine starts or engine trim operations, radiating electromagnetic energy, or using NDI or welding equipment.
    • Maintenance, including pre/postflight inspections, may be performed on adjacent aircraft, but no spilled flammable liquids should be present.

    Servicing Constraints

    • Only personnel required for the operation should remain in the FSSZ during servicing.
    • Smoking is not allowed within 50 feet of any aircraft or servicing operation.
    • Aircraft radar and HF radios should not be operated in the transmit mode within 300 feet of servicing operations.
