1、Designation: F 2122 08An American National StandardStandard Practice forTreestand Safety Devices1This standard is issued under the fixed designation F 2122; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision.

2、 A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice provides guidance for providing usersafety devices on treestands.1.2 The values stated in inch-pound units are to be

3、regardedas standard. No other units of measurement are included in thisstandard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and det

7、 nsystem that is assembled for thepurpose of arresting an accidental fall of its user. A FASconsists of a full body harness, lanyard, anchorage means, andconnecting.3.2.5 full body harness, ncomponent with a design ofstraps that is fastened about the person in a manner so as tocontain the torso and

8、distribute the fall arrest forces over atleast the upper thighs, pelvis, chest, and shoulders, with meansfor attaching it to other components or subsystems.3.2.6 handclimber, or climbing aid, ndevice to assistclimbing with a climbing treestand. A structure that allows theuser to support his weight w

(The laddertreestand may be secured to the tr

(The user usually ascends the tree by some meansand then lifts the treestand to

11、 the desired position and securesit for use.)3.2.10 platform, nhorizontal structural area of a treestandon which the user stands and/or places his feet.3.2.11 suspension relief device, ndevice to allow relief ofa persons weight on the lower extremities if suspended in aharness. The device is to help

Summary of Practice4.1 This practice provides guidelines for the selection,availability and placement of user safety devices on treestandsand climbing sticks particularly for quality assurance andadequacy of auxiliary safety including:4.1.1 Use of instructions in

14、anticipation of user error ormisuse.4.1.2 Availability of instructions in case of their loss.4.1.3 User fall protection (fall arrest system).4.1.4 Interconnects (two piece units).4.1.5 Auxiliary security.1This practice is under the jurisdiction of ASTM Committee F08 on SportsEquipment and Facilities

Significance and Use5.1 T

17、his practice is provided to develop and maintainuniformity in practices for availability, use, and selection ofsafety devices on treestands and climbing sticks, particularlywith regard to quality assurance and safety.5.2 It is emphasized that the use of these practices will notalter the validity of

18、data determined with specific tests, butprovides guidance in the interpretation of test results (valid orinvalid) and guidance in the selection of a reasonable generalprovision in those instances where no standard exists today.6. Procedure6.1 It is recommended that manufacturers follow the meth-ods

19、of safety provisions so described herein. When unusual orspecial conditions require auxiliary safety devices, means ormethods not covered herein, the manufacturer shall be respon-sible for their development to assure adequate availability forthe user.6.2 Selection of Safety Devices:6.2.1 User instru

20、ctions shall be supplied with each indi-vidual unit and shall be in accordance with Practice F 2123.6.2.1.1 Instructions shall contain detailed information on theproper set up, use and safety precautions for the unit.6.2.2 Labels and warnings shall be placed on the unit inaccordance with Practice F

21、2121.6.2.2.1 Notice of availability of instructions will be identi-fied on the unit as a part of required label information as givenin 6.2.2.6.2.3 A fall arrest system that meets Test Method F 2337shall be provided with each treestand as standard equipment.The fall arrest system capacity shall not b

22、e less than the ratedcapacity of the treestand, except for a two person treestand (see6.2.3.3).6.2.3.1 The fall arrest system shall have provision to besecured to the tree that the user climbs. It shall be soconstructed that the user is able to adjust and minimize thefree-fall length.6.2.3.2 In the

23、case of climbing treestands, the features of thefall arrest system shall include allowing the user to have itsecured to the tree while in the process of climbing the tree.6.2.3.3 For two person treestands, there shall be a fall arrestsystem provided for each person, that is, two FAS. The fallarrest

24、system rated capacity shall be a minimum of 300 lb.6.2.3.4 Ladder treestands shall include means to stabilizethe ladder from pivoting about the ladder axis and secure it tothe tree prior to use. Crisscrossing rope, straps, or othermethods to secure the ladder treestand to the tree to preventpivoting

25、 prior to climbing is an example of such means.Instructions shall include proper installation and use.6.2.4 Two-piece climbing treestands (those without integralseats) specifically, those involving a “stand-up/sit-down” modeof ascending or descending a tree, shall include a flexibleinterconnecting d

26、evice to secure the upper and lower piecestogether and prevent them from separating.6.2.4.1 A cable, rope, strap or other similar interconnectingmeans, shall be configured such that it will not encumber theuser while climbing while prohibiting the lower part fromfalling if the lower part were to bec

27、ome disengaged from theuser.6.2.4.2 The use of a device to secure the upper piece (seat)whenever the user removes the load (standing) is highlyrecommended. An elastic cord, rope, strap, etc. should be anintegral component of the upper piece and its use explained inthe unit instructions.6.3 Auxiliary

28、 safety devices shall be provided where addi-tional safety precautions can be made to further protect theuser. Examples include: anti-slip platform surfaces, backbarlocking devices or tie-offs (for climbing treestands, use ofhandclimbers for locking means, balance bars, etc.).6.3.1 For special cases

29、 or non-typical units, specific safetydevices shall be provided where applicable.6.4 Ladder treestands and tripod stands shall include meansto secure all vertical platform support sections together suchthat inadvertent separation of the sections during use cannotoccur. The use of pins, bolts, clips,

30、 etc. through each joint (orother coupling device) to prevent sections/columns from sepa-rating if subjected to tension loads is an example of suchmeans.6.5 A suspension relief device shall be provided completewith instructions. This device shall be capable of allowing theuser to relieve the load on

31、 the users lower extremities ifsuspended in a harness to help maintain circulation in the legsand help prevent suspension trauma (blood pooling). Thecapacity rating of the suspension device shall equal the FASrated capacity.7. Keywords7.1 backbar; climbing stick; platform; treestand; tripodF2122082A

Criteria has been developedfor certification of treestands and this practice is an integralpart of the certification. However, a treestand conforming

33、 tothis practice alone does not constitute certification and thosemanufacturers desiring certification must meet all applicablestandards as a minimum requirement.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this st

34、andard.
