Summary of Practice4.1 This guide is based in part upon recommendations of the

19、CPSC, the American Association of Pediatrics, the NationalCenter for Injury Prevention, and the American MedicalAssociation. It also incorporates certain provisions of theAPSPModel Barrier Code for Residential Swimming Pools, Spas andHot Tubs (ANSI/APSP-7).4.2 The CPSC recommends the use of barriers

20、 and othersafety devices to create “layers of protection.” PerformanceSpecifications F1346 and F2286 and Guide F2518 describevarious other layers that should be used in conjunction withthis guide to reduce the risk of drowning for children under theage of five in residential swimming pools, hot tubs

21、, and spas.5. Significance and Use5.1 This guide sets forth minimum standard requirementsfor use in local codes and ordinances relating to residentialoutdoor swimming pools, hot tubs, and spas.5.2 This guide does not have the effect of law, nor is itintended to supersede local codes and ordinances o

22、f a morerestrictive nature.5.3 Studies, as listed in Annex A1, have been referenced asthe bases for certain recommendations in this guide and willassist those who intend to provide protection against drowningsand near-drownings by restricting access to children under theage of five years in resident

23、ial swimming pools, spas, and hottubs. This would include, but not be limited to, state and localgovernments, model code organizations, building code groups,and consumers. It is understood that the format will varydepending upon the specific use and local conditions.6. Requirements6.1 HeightThe top

24、of the fence shall be a minimum of 48in. (1219 mm) above grade measured on the side of the fencethat faces away from the swimming pool. If the fence ismounted on top of an above ground pool, the top of the fenceshall be a minimum of 36 in. (914 mm) above the top of thepool structure, provided the to

25、p of the pool structure is aminimum of 48 in. (1219 mm) above grade (see 3.2.2 fordefinition of grade specific to this guide).6.2 VisibilityThe fence on top of an above ground poolshall be so designed and constructed that it has at least a 65 %open area to allow visibility from a designated supervis

26、ing areaoutside the pool area to inside the pool area.6.3 Ground Clearance The maximum vertical clearancebetween grade and the bottom of the fence shall be 4 in. (102mm) measured on the side of the fence that faces away fromthe swimming pool. Where the top of the pool structure isabove grade, such a

27、s an above ground pool, the fence may beat ground level or mounted on top of the pool structure. Wherethe fence is mounted on top of the pool structure, the spacebetween the top of the pool structure and the bottom of thefence shall be no greater than 4 in. (102 mm) in any direction.6.4 Solid Barrie

28、rs that do not have openings, such asmasonry or stone walls, shall not contain indentations orprotrusions except for normal construction tolerances andtooled masonry joints. Such indentations shall not be deeperthan 0.375 in. (10 mm).6.5 Horizontal and Vertical Members Where the fence iscomposed of

29、horizontal and vertical members and if thedistance between the tops of the horizontal members is lessthan 45 in. (1143 mm), the horizontal members shall not extendmore than 0.375 in. (10 mm) outside of the enclosure, and thespacing between the vertical members shall not exceed 134 in.(44 mm) (see Fi

30、g. 1). If the distance between the tops of at leasttwo consecutive horizontal members is 45 in. (1143 mm) ormore, the spacing between the vertical members shall notexceed 4 in. (102 mm) (see Fig. 2). Where there are decorativecutouts, the spacing within the cutouts shall not exceed 134 in.(44 mm).6.

31、6 Chain Link FencesMesh opening for chain link fencesshall be a nominal 114 in. (32 mm) measured between theparallel sides of the mesh, and a maximum of 134 in. (44 mm)measured horizontally between the corners of the installedmesh, as illustrated in Fig. 3 (see Note 1), unless the fence isprovided w

32、ith privacy slats (see Note 2) fastened at the top orthe bottom, in which case no opening in the mesh shall exceed134 in. (44 mm).NOTE 1If the tolerance of 618 in. (3.2 mm) indicated in Specifica-tions A392, A491, F668, F1183, and F1345 is rigidly applied to anordered nominal mesh size of 114 in. (3

33、2 mm) measured between theparallel sides of the mesh, the result could be a dimension exceeding thespecified maximum of 134 in. (44 mm) measured horizontally between theFIG. 1 If Horizontal Members are Less Than 45 in. Apart, VerticalSpacing Shall Not Exceed 134 in.F1908 08 (2018)2corners of the ins

34、talled mesh. The degree of tension applied to the fabricduring installation could also affect this horizontal dimension. In all cases,the horizontal opening between the corners of the fabric mesh aftertensioning shall not exceed 134 in. (44 mm).NOTE 2Caution Regarding Privacy SlatsPrivacy slats wher

35、e usedshall not violate the requirements of 6.2 regarding visibility.6.7 Diagonal Members:6.7.1 Where the fence is composed of diagonal members,such as in a lattice fence, any opening created by the diagonalmembers located less than 48 in. (1219 mm) above grade shallbe a maximum of 134 in. (44 mm) m

36、easured in its largestdirection.6.7.2 Diagonal bracing members extending from one side tothe opposite side creating a ladder effect on all styles of fencesand gates are not permitted where spacing of vertical membersin any area between posts exceeds 134 in. (44 mm).6.8 Access Gates:6.8.1 Double Leaf

37、 access gates shall comply with therequirements of 6.1 6.6 and shall be equipped with a padlockor other key-operated locking deice that must be locked whenthe gate is not in use.6.8.2 Single Leaf access gates shall open outward awayfrom the pool, shall be self-closing, and shall have a self-latching

38、 device. Where the release mechanism of the self-latching device is located less than 54 in. (1372 mm) abovegrade, the release mechanism shall be located on the pool sideof the gate a minimum of 3 in. (76 mm) below the top of thegate and the gate and fence shall have no opening greater than12 in. (1

39、3 mm) within 18 in. (457 mm) of the releasemechanism when the gate is in the fully closed position (seeFig. 4).6.9 The fence shall completely surround the pool structurewhen practical. Where a building or dwelling or portion thereofmust be utilized as part of the pool enclosure, and if theexterior w

40、all or walls of that portion of the building containsdoors, windows, or other openings refer to PerformanceSpecifications F1346 and F2286 and Guide F2518 to installand ensure the proper layers of safety.6.10 Above-Ground Pools or On-Ground Pools:6.10.1 Pool WallAn above-ground or on-ground pool wall

41、itself may be the barrier if the pool structure is on grade and thewall is at least 48 in. (1219 mm) in height. Other types ofbarriers can be mounted on the pool structure or can surroundthe pool at ground level. Where the barrier is mounted on theFIG. 2 If Horizontal Members are Equal to or More Th
