   2. (2) The fueling or defueling of an aircraft is prohibited while an engine or engines of the aircraft are operating.
   3. (3) The operation of any electrical appliance in an aircraft is prohibited when the aircraft is being fueled or defueled.
   4. (4) During the fueling or defueling of an aircraft, the aircraft fueling and defueling equipment (such as hoses and funnels) shall be electrically grounded or bonded.
   5. (5) When a fuel spill occurs at or near a fuel delivery device, the Administration shall be notified immediately. Valves and dome covers shall be shut down and the fueling vehicle shall remain in place until the arrival of fire department vehicles. If the engine of the fueling vehicle is running at the time of the fuel spill, it shall remain running until orders otherwise are issued by the fire department incident commander at the scene. Conversely, if the engine of the fueling vehicle is shut down at the time of the fuel spill, it shall remain shut down until the fire department incident commander at the scene orders the vehicle removed. Fueling or defueling operations may not resume following a fuel spill until all affected areas are thoroughly cleaned.
   6. (6) Only fueling/defueling personnel, and other personnel expressly authorized by an air carrier in accordance with approved operating procedures, are permitted within 50 feet of an aircraft during fueling and defueling operations. Fueling operators shall possess an Oil Operator's Certificate issued in accordance with COMAR 26.10.01.
   7. (7) A person may not be aboard an aircraft during fueling or defueling unless a cabin attendant is present at or near the cabin door and unless a passenger boarding ramp or bridge is in place at the cabin door.
   8. (8) During fueling or defueling, the use of any material which may cause a static spark is prohibited.
   9. (9) Fueling or defueling operations may not begin unless fire extinguishers are within ready reach.
   10. (10) Starting the engine of an aircraft when there is any flammable or combustible liquid on the ground in the vicinity of the aircraft is prohibited.
   11. (11) It is prohibited to fuel or defuel an aircraft with any equipment or apparatus which is not in a safe, sound, and nonleaking condition.

2. B. The fueling and defueling of aircraft and the maintenance of an aircraft fueling system may not be conducted within 50 feet of any hangar or other building, except as conducted in compliance with:

   1. (1) NFPA 407 Aircraft Fuel Servicing; and
   2. (2) NFPA 410 Aircraft Maintenance.
3. C. Parking fueling vehicles in areas other than those assigned by the Administration except for the accomplishment of minor adjustments or repairs necessary to move the vehicle to a designated storage or repair area is prohibited. Fuel trucks, empty or otherwise, are not permitted within any building at the Airport unless the building is properly designed and equipped for fuel truck repair purposes. Fueling or defueling aircraft in any building is strictly prohibited.
4. D. An operator may not back a fueling vehicle anywhere on the Airport unless an attendant is present outside the fueling vehicle to assist.
5. E. Fueling operations shall be stopped when a fire is detected within 300 feet.
6. F. The operation or ground testing of airborne radar equipment is prohibited except in areas approved for that purpose. Aircraft radar directional beams may not be operated near another aircraft, fueling operations, fueling trucks or flammable liquid storage when the high intensity beam emitter is within a 300-foot radius or the low intensity beam emitter is within a 100-foot radius.
