16、 recommendations in this guide and willassist those who intend to provide protection against injuries orfatalities associated with anticipated thrown or hit balls andbats as well as passage to or from a ballfield or other sportsenvironment, thus restricting and deterring passage. Thiswould include,
17、but not be limited to, state and local govern-ments, model code organizations, building code groups, andconsumers. It is understood that the format will vary dependingupon the specific use and local conditions.5.4 Articles and studies have noted that fencing for baseballor softball sports, or both,
18、should exist for baseball and softballsports outfields, player seating, and sidelines.6. Dimensions and Materials6.1 Permanent Outfield Fence:6.1.1 HeightThe top of the fence shall be a minimum of96 in. 2.4 m above grade measured on the side of the fencethat faces away from the ballfield (see 3.2.3
19、for the definitionof grade specific to this guide). The height is to be such thatplayers in the outfield can safely attempt to catch a fly ballwithout impaction on the kidneys, back, or head. However, incircumstances where it is necessary to protect people or objectsoutside the fences, the height sh
20、ould be increased accordingly.Top rail padding systems may also be used. A mid rail is notneeded, in accordance with Specification F 668.6.1.2 Ground ClearanceThe maximum vertical clearancebetween grade and the bottom of the fence shall be no morethan a 1 in. 25.4 mm reveal or space, measured on the
21、 side ofthe fence that faces the ballfield, to avoid entrapment of feet.6.1.3 PanelsSolid barriers and safety padding that doesnot have openings, such as plastic, plywood, or canvas, shallnot contain indentations or protrusions, except for normalconstruction tolerances and joints. Such indentations
22、shall notbe deeper than 0.375 in. 9.5 mm and should be flush facingthe ballfield.6.1.4 Horizontal and Vertical MembersWhere the fence iscomposed of horizontal and vertical members, the structuralmembers shall be located on the side opposite of the playenvironment to prevent encountering the member.
23、The spacingbetween the vertical or horizontal members shall not exceed134 in. 4.44 cm. If of a lattice design, the members shall bediagonal.6.1.5 Diagonal Members:6.1.5.1 Where the fence is composed of diagonal or otherangular positioned members, such as in a lattice fence, anyopening created by the
24、 diagonal members shall be a maximumof 134 in. 4.44 cm measured in its largest direction, to preventtoe holds. Such members should be on the side away from theballfield.6.1.5.2 Diagonal bracing members extending from one cor-ner to the opposite corner, creating a ladder effect on all stylesof fences
25、 and gates, are not permitted where spacing of verticalor horizontal members in any area between posts exceeds 134in. 4.44 cm, in order to prevent climbing into the ballfield.6.1.6 Fabric or MeshMesh opening for chain-link andother fence fabrics shall be a minimum of 2-in. 5-mm mesh,9 gauge. All cha
26、in-link fabric shall have a knuckle and knuckleselvage and shall be selected from chain-link fabric in accor-dance with Specifications A 392, A 491, F 668,orF 1345.Other materials shall have blunt edges.6.2 Portable Outfield Fence:6.2.1 Portable outfield, and often sideline, fencing is gener-ally us
27、ed when it is necessary to reconfigure the playing fieldboundary for games in which the classification will change orwhen the field is to have multiple uses. The potential for injurycaused by an outfielder colliding with a fence that does notmeet resiliency, break away, or fall-down requirements iss
28、ignificant. The added criteria that must be considered is thestability of the cross or horizontal pieces, supports, the panelfabric opening, the vertical pieces and their give away, and theheight. Portable fence systems made of specially formulatedpolymers in approximate 10-ft 3.05-m lengths with br
29、eak-apart connections and stable support should allow panels torelease and fall down in sections when impacted. The collaps-ibility feature should prevent cartwheeling over the fence andallow the outfielder to be lowered to the ground in a fall. Thedowned panel should quickly and easily return to it
30、s originalposition and be snapped into place.6.3 Wood Outfield Fence:6.3.1 HeightThe top of the fence shall conform to heightfor other fence types.6.3.2 Ground Clearance The clearances shall conform toprior appropriate sections to eliminate foot entrapment.6.3.3 PanelsThe panels should conform to pr
31、ior appro-priate sections with the flush side inside the playing area andshall be covered with a wall padding.6.4 Foul Line Fencing:6.4.1 HeightThe top of the fence shall be a minimum of96 in. to 8 ft 2.44 m above grade measured at the side of thefence from the ballfield where any sideline obstructi
32、ons exist orwhere objects such as other activity areas, parking lots, and soforth have to be protected.6.4.2 Ground Clearance The clearance shall conform toprior appropriate sections to eliminate foot entrapment.6.4.3 PanelsThe panels should conform to prior appro-priate sections.6.4.4 Horizontal an
33、d Vertical MembersThe horizontaland vertical members shall conform to prior appropriatesections.6.4.5 Diagonal MembersThe diagonal members shallconform to prior appropriate sections.6.4.6 Fabric or Mesh The fabric or mesh shall conform toprior appropriate sections.6.5 Spectator Protective Fencing:6.
34、5.1 HeightThe top of the fence shall be a minimum of8 ft, 0 in. 2.44 m above grade or of a greater dimension thatensures protection of spectators from a fouled line drive orrelated trajectory.6.5.2 Ground ClearanceThe clearance shall conform toprior appropriate sections to eliminate foot entrapment.
35、6.5.3 PanelsThe panels shall conform to prior appropriatesections.F20000626.5.4 Horizontal and Vertical MembersThe horizontaland vertical members shall conform to prior appropriatesections.6.5.5 Diagonal MembersThe diagonal members shallconform to prior appropriate sections.6.5.6 Fabric or MeshThe f
36、abric or mesh shall conform toprior appropriate sections.6.6 Player Bench Protective Fencing:6.6.1 HeightThe top of the fence shall be a minimum of72 in. (6 ft) 1.83 m abovegrade measured at the side of theplay side of the fence.6.6.2 Ground ClearanceThe space from the fence bottomand ground shall c

38、.7 Backstop Fencing:6.7.1 Backstops provide a containment of pitched, thrown,and batted balls. It should delineate the spectator area from theplayfield. It most often consists of three panels; one panelcentered behind home plate with the other two panels locatedat the end of the center panel at an a
39、ngle of 45 to the centerpanel and parallel to the foul lines.6.7.2 Backstops should be of a protective mesh of eitherchain-link or synthetic net materials of a 2 in. 5 mm mesh toprevent climbing.6.7.3 Backstop center panels should be no less than 25 ft7.62 m behind home plate. The side panel should
40、be no lessthan 25 ft from the foul lines.6.7.4 The backstop height and width may vary dependingon the type of ball being played, the size and height of thespectator area around it, and other structures or objects thatshould be protected from foul balls, passed balls, wild pitches,and overthrows. The
41、 minimum height for backstops should be16 ft 4.88 m. The height should be determined by the extentof protection of the spectators while standing behind it at thehighest level of seating. The minimum width of the panels isdependent upon the structural design supporting the chain-linkor net fabric.6.7
42、.5 The backstop overhang panels should be installed atthe top of the center and wings of a design that meets heightregulations of the game played.6.8 Access Gates:6.8.1 Double-leaf access gates shall comply with the re-quirements of prior appropriate sections and shall be equippedwith a padlock devi
43、ce.6.8.2 Single-leaf pedestrian access gates shall open outwardaway from the play environment, shall be self-closing, andshall have a self-latching device. The release mechanism shallbe located on the side opposite of the play environment or thegate. It shall be of a height to facilitate egress/acce
44、ss below thetop of the gate. The gate and fence shall have no openinggreater than12 in. 13 mm within 18 in. 457 mm of therelease mechanism when the gate is in the fully closed position.7. Location7.1 Outfield FenceThe outfield fences are located by aradius measurement from home plate. The radius dis
45、tance isdetermined by the level and type of ball play expected on thefield and in conformance with the efforts of ASTM CommitteeF08 for classification of field systems. There should be nophysical obstructions between the backstop and the outfieldfence, light poles, and foul ball markers, and other e
46、quipmentshould be located outside the playing field fence.7.2 Foul Line FenceThe foul line fence is designed toprotect the fielder from obstructions and other sideline objects,to contain the ball and prevent spectators from intruding ontothe field. The fence shall be offset to the entire foul line f
47、roma point opposite the first and third bases toward the outfieldfence. The minimum distance between the foul line and thefence at the outfield fence shall be 10 ft. 3.05 m. Theminimum distance between the foul line opposite the bases andthe fence line shall be 25 ft. 7.62 m. The fence line may runa
48、t an angle between the two points but in a straight andunbroken line to prevent unanticipated encounter by a playerwith the fence that is angled closer to them along the foul line.See Figs. 1-3.7.3 Spectator Protective FenceThe spectator fence shallbe located where spectators will congregate to watc
49、h the gameor in front of bleachers of an 8 ft height or of a sufficient heightto protect spectators at the highest point of the bleachers.7.4 Player Bench Protective FenceThe player benchfence shall be located in front of all player benches ofa6ftheight.7.5 Backstop FenceThe backstops shall conform to priorappropriate sections applicable to backstops.7.6 GatesThe gates shall be placed to provide emergencyand maintenance access to the field as well as for officials useand player use.8.
