(c)  
Make sure that persons that do not know of the hazard areas near the power plant cannot go in these areas.

 S 842-008-C00
 WARNING: ALL PERSONS MUST STAY OUT OF THE DANGEROUS AREAS THAT ARE
_______
 FORWARD OF THE AIR INLET, AND THE SIDES OF THE AIR INLET. ALL
 PERSONS MUST STAY AWAY FROM THE ENGINE SAFETY BARRIER WHEN THE
 ENGINE IS OPERATED. DURING THE ENGINE OPERATION, THERE IS
 SUFFICIENT SUCTION AT THE AIR INLET TO PULL A PERSON INTO THE
 INLET. A FATAL INJURY COULD OCCUR.

 CAUTION: THE SUCTION NEAR THE AIR INLET CAN PULL IN HATS, GLASSES, LOOSE
_______
 CLOTHING AND WIPE RAGS FROM YOUR POCKETS. ALL LOOSE OBJECTS
 MUST BE REMOVED BEFORE YOU WORK AROUND THE ENGINE.

 (2)  
When the engine operates, it makes a low air pressure area in the
 inlet.

 (a)  
This low pressure area causes a large quantity of air to move from the forward side of the inlet cowl and go into the engine.

 (b)  
The air which is near the inlet moves at a much higher velocity than air which is farther from the inlet.

 (c)  
The quantity of the engine suction does not increase slowly and continuously when you go near the inlet.

 (d)  
The suction is small until you get near the inlet, where the suction increases suddenly.

(e)  The engine suction can pull small objects into the engine easier than it can pull large objects.
 S 842-009-C00
 (3)  Before you operate the engine, do these steps:
 (a)  
Make sure there are no tools, unwanted materials or objects in the air inlet.

 (b)  
Make sure the area 40 feet to each side and forward of the power plant is clean.

 (c)  
Make sure the ground which is forward of the engine is strong and solid.

 (d)  
Make sure the suction of the engine will not pull the unwanted material on the ground into the engine.

 (e)  
Make sure that persons with loose objects (such as hats, eyeglasses, loose clothing, or rags) do not go into this area.

 (f)  
When an engine is operated, use an engine inlet guard.

 1)  This will prevent persons from being pulled into the inlet because of air suction from the engine.
 S 842-010-C00
 (4)  
It is recommended that ground persons stay outside of the inlet hazard area for at least 30 seconds after the fuel cutoff signal (start lever placed in CUTOFF position) from the flight compartment.

Engine Exhaust (Fig. 201)

 S 842-011-C00
 WARNING: ALL PERSONS MUST STAY OUT OF THE DANGEROUS AREAS THAT ARE AFT
_______ OF THE POWER PLANT. DURING THE ENGINE OPERATION, THERE ARE HOT GASES AND HIGH SPEED AIR WHICH CAN CAUSE INJURY TO PERSONS AND DAMAGE TO EQUIPMENT.
 (1)  
Figure 201 shows the hazard areas near the exhaust with dangerous
 air conditions.

 S 842-012-C00

 (2)  
When the engine operates, a large quantity of exhaust comes from the aft end of the engine.

 (a)  
The exhaust is hot and moves at high speed.

 (b)  
There are contamination and bad gases which were pulled into the engine by suction.

 (c)  
There are gases from the fuel that has burned or fuel which has not burned.

 S 842-013-C00
 (3)  At high power, the fan and turbine exhaust can blow loose dirt,
 stones, sand and other unwanted materials a distance of 300 feet.

 (a)  The airplane must be parked at an area where injury to persons or damage to equipment or other airplanes can be prevented.
