“Safety fan” applies only to rifle and pistol firing ranges. The safety fan of a firing range consists of three parts: the direct fire zone, the safety zone, and the ricochet zone. The direct fire zone is that area into which all shots are fired during the normal course of shooting. This zone includes all directions and angles of fire used on a firing range while shooting at a specific target, either stationary or moving, from a specific firing point. The length of the direct fire zone extends to the maximum range of the ammunition and firearm used on the firing range, but can be shortened by physical barriers or other devices which reduce the maximum distance of a bullet’s trajectory. The safety zone extends 10 degrees to the left and right of the direct fire zone and protects against errant bullets caused by cross fire or accidental discharge of a firearm. The ricochet zone is that area 45 degrees to the left and right of the firing line, and extended a certain distance dependent on the type of firearm and ammunition allowed on the range (i.e., 85 yards for air guns, and up to 1,200 yards for high-powered rifles). The line is then extended parallel to each side of the safety zone downrange to the intersection of a line extended from the terminus of the direct fire zone through the outer corner of the safety zone."

Thank you!

I finally found the section you posted, here, under 10.22.050 Definitions.
