1. When you are near any aircraft the "Circle of Safety" must be adhered to. The "Circle of Safety" is an imaginary line around any aircraft ten (10) feet outside the nose, wing tips and the tail. If the motors are not running you must maintain at least the Circle of Safety around the aircraft.
IF THE MOTORS ARE RUNNING ON ANY AIRCRAFT YOU MUST APPROACH ONLY FROM DIRECTLY BEHIND THE TAIL OF THE AIRCRAFT, WITH AT LEAST THESE DISTANCES BETWEEN YOU AND THE AIRCRAFT TAIL:

Military

C-130  -- 100 feet
C-141  -- 200 feet
C-5A   -- 300 feet
KC-10 -- 300 feet

Civil Reserve Air Fleet. (CRAF)

707, 727, 737 -- 150 feet
747 -- 300 feet

WHEN IN DOUBT, INCREASE THE DISTANCE BETWEEN YOU AND THE TAIL OF THE PLANE.

2.) When loading or unloading the aircraft:

a.) wear leather gloves
b.) remove your rings, watches and bracelets
c.) bring and wear ear and eye protection - the dust and noise of these large
aircraft are dangerous.
  3.) Remember personal safety measures.

                    a.) Do not wear your hat or loose clothing around aircraft engines that are
                         running.  They can easily be sucked into the engines.

                    b.) Do not stand on the ramp of the aircraft unless the ramp of the aircraft is
                         touching the ground.

 c.) If you have to move from the forward to the aft part of the aircraft, try to
     use the cabin space. If the motors are not running, you may walk around
     the wing tips to the tail section.

d.) All personnel boarding the aircraft must have an ESCORT between the
     holding area and the loading area of the aircraft.

                     e.) There is no smoking on flights of less than 6 hours.
