WARNING:_______ STAY AWAY FROM THE HAZARD AREAS IN THE FRONT AND THE REAR OF
 THE POWER PLANT.  IF YOU USE THE ENGINE SAFETY BARRIER, YOU
 MUST STAY OUT OF THE ENGINE SAFETY BARRIER DURING THE GROUND
 OPERATIONS.  THE ENGINE CAN CAUSE SUFFICIENT SUCTION AT THE
 INLET DUCT TO PULL A PERSON INTO THE DUCT AND CAUSE INJURY.
 THUS, WHEN YOU GO NEAR A JET ENGINE, YOU MUST FOLLOW THE
 PRECAUTIONS TO STAY AWAY FROM THE INLET AIRFLOW.  THE SUCTION
 FROM THE INLET CAN ALSO PULL IN HATS, GLASSES, LOOSE CLOTHES
 AND WIPE-RAGS FROM POCKETS.  YOU MUST ATTACH OR REMOVE LOOSE
 OBJECTS BEFORE YOU DO THE WORK AROUND THE ENGINE.  IF YOU DO
 NOT FOLLOW THESE INSTRUCTIONS, INJURY TO PERSONS OR DAMAGE TO
 EQUIPMENT CAN OCCUR.
 WARNING:_______ DO NOT USE THE SERVICE INTERPHONE JACK ON THE ENGINE NACELLE OF
 THE ENGINE YOU WILL START OR WHICH IS IN OPERATION.  IF YOU DO
 NOT OBEY THESE INSTRUCTIONS, THE ENGINE INLET SUCTION OR THE

 EXHAUST BLAST CAN CAUSE INJURY TO PERSONS.
 (1)  
You must be very careful during an engine operation to prevent injury to persons and damage to property. You must stay away from the engine inlet and the exhaust nozzle. The air suction can pull persons or unwanted material into the engine inlet. The hot exhaust gases go out of the exhaust nozzle at high speeds. Also, the speed of the air that goes out of the fan is sufficiently high to cause injury. When the thrust reverser is in the reverse thrust position, the fan air goes out in the forward direction and not the rearward direction.

 (2)  
Make sure you clean and examine the engine compartment, the air inlet, and the work area before the engine operation to make sure there are no unwanted materials.

 CAUTION: DO NOT INSTALL TIES OR STRAPS FROM THE FAN BLADES TO THE FAN
_______ EXIT GUIDE VANES TO HOLD THE ROTOR. IF YOU INSTALL THE TIES OR STRAPS, DAMAGE TO THE ENGINE CAN OCCUR.
 (3)  When it is necessary for the task, use the general safety items that follow to prevent an accident.

 (a)  The hazard areas are made at the wind static conditions of standard sea level.

Exhaust Properties

 S 862-014-N00
 (1)  Velocity
 (a)  At high engine speeds, the air (which flows out of the fan and the engine exhaust) can blow loose dirt, stones, sand and other material at a distance of more than one hundred feet. Thus, you must use caution when you park the aircraft for a high speed operation to prevent injury to persons or damage to property or other aircraft. A blast fence is recommended if you will operate the engines at high power in an area where sufficient space to decrease the speed of the fan and exhaust blast is not available.
 S 862-015-N00
 (2)  Temperature
 (a)  There is high temperature air more than one hundred feet from the exhaust nozzle in some wind conditions. Near the engine, the high exhaust temperature can cause deterioration of the bituminous pavement. Thus, concrete aprons are recommended for areas of a high power operation. When you start an engine which has fuel in the turbine exhaust area, long flames can blow out of the exhaust nozzle. You must examine this possible dangerous condition and keep all flammable materials away.
 S 862-016-N00
 (3)  Toxicity
 (a)  Tests show that the quantity of carbon monoxide in the exhaust is small, but other gases are also in the exhaust. These other gases smell bad and are dangerous to your body. If you are near these gases, they can cause injury to your eyes. But more important, they can cause you not to breathe correctly. Because of these two results, you must not get near the gases, specially in small areas where the concentration is large.
