(2)  
Use only approved fuel servicing equipment in a serviceable condition.

(3)  
Do not disable the fueling shutoff (deadman) controls.

NOTE:  Wire, rope or tools used to disable the deadman control can prevent the immediate shutoff of pressurized fuel.  A disabled deadman control can cause a fuel spill hazard.

(4)  
When you position fuel servicing vehicles, make sure the equipment:

(a)  
Has a clear exit path at all times

(b)  
Does not interfere with access to the aircraft for rescue or fire protection

(c)  
Does not obstruct the passenger evacuation routes

(d)  
Does not obstruct the chute deployment areas.

J.  Ground Equipment and Airplane Servicing Equipment Precautions
(1)  
Obey all separation distance requirements (Table 301).

WARNING:  OBEY THE FUEL SERVICING EQUIPMENT PRECAUTIONS DURING A REFUEL OPERATION.  IF YOU DO NOT OBEY THESE REQUIREMENTS, A FIRE OR EXPLOSION CAN OCCUR.

(2)  
Do not put ground equipment below the fuel system vents at the wingtips.  The fuel tanks are vented through the wingtip vents. An explosive mixture of fuel vapor can exist at these locations.

(3)  
Added fuel weight will compress the landing gear shock struts and lower the airplane. Make sure all stands, ladders, vehicles and equipment that can come in contact with the airplane are removed before the refuel operation begins.

K.  Personnel Precautions
(1)  Personnel that refuel the airplane must be trained in the safe operation of these systems and procedures:
WARNING:  OBEY THE PERSONNEL PRECAUTIONS.  IF YOU DO NOT OBEY THESE REQUIREMENTS, INJURIES TO PERSONS AND DAMAGE TO EQUIPMENT CAN OCCUR.
(a)  
737 fuel servicing operations

(b) 
 Fuel servicing equipment

(c)  
Fuel spill prevention

(d) 
 Emergency controls

(e) 
 Emergency equipment

(f)  
Emergency fuel spill and fire protection procedures

(g)  
Fuel vapor hazard locations (wing tips, engine locations, etc.).

(2)  
Wear eye protection (chemical splash goggles or safety glasses and face shield) during the connection of the fuel hose and during the initial pressurization of the hose after hookup.

(3)  
At some airport locations, a fuel safety person may be needed to oversee aircraft refueling operations.

L.  Fueling Zone
(1)  
Refuel operations must only be done in airport approved areas.  Fire protection, emergency rescue equipment and correct separation distances will be available in these areas.

WARNING:  OBEY THE FUELING ZONE PRECAUTIONS.  IF YOU DO NOT OBEY THESE REQUIREMENTS, A FIRE OR EXPLOSION CAN OCCUR.

(2)  
A fueling zone exists around the airplane anytime an airplane is preparing for or during a refuel operation.

(3)  
Fire and rescue equipment, including approved fire extinguishers, must be available.

(4)  
Within the fueling zone, obey these requirements:

(a)  
Obey the equipment separation requirements (Table 301 and 302).

(b)  
Only authorized persons and vehicles are permitted.

(c)  
Passengers are not permitted.

(d)  
All personnel must assume that a refuel operation is in progress any time a fuel servicing vehicle is in the fueling zone.

(e)  
Limit maintenance activity on the airplane to work that does not increase the risk of igniting fuel vapor.

(f)  
All electrical equipment must be rated for the hazardous location zone where it will operate.

(g)  
Do not keep vehicle engines running unless necessary for aircraft maintenance or servicing.

(h)  
Metal wheels or studded tires are not permitted.

(i)  
Do not approach within 50 feet (15 meters) of the airplane with these items: 1) Open flames 2) Heat sources 3) Lighted smoking material 4) Shoes with metal clips 5) Other potential ignition sources

M.  Adverse Weather Conditions Precautions
(1)  When thunderstorms or lightning are in the area, approximately a 10-mile (16-kilometer) radius, do these steps:
WARNING:  STOP THE REFUEL OPERATION DURING ATMOSPHERIC ELECTRICAL ACTIVITY.  DO NOT CONNECT A HEADSET AND DO NOT TOUCH ELECTRICAL CONNECTIONS TO THE AIRPLANE.  LIGHTNING STRIKES CAN CAUSE INJURIES TO PERSONS, AND A FIRE OR EXPLOSION DURING A REFUEL OPERATION.
