Minimum performance criteria for harnesses and energy absorbing lanyards in arresting a fall after exposure to electric arcs are included for workers who may be exposed to thermal hazards of momentary electric arcs or flame.1.2 Equipment may fall within one of the following categories:1.2.1 Fall (Travel) Restraint—Prevents a user from reaching a fall hazard (allow 0 fall distance).1.2.2 Work Positioning—Allows a 2 ft maximum free fall distance.1.2.3 Fall Arrest—Allows a 6 ft maximum free fall distance with a maximum arrest force of 1800 lb.NOTE 1: Under certain conditions and with the use of equipment designed for such conditions, a 12-ft free-fall distance with a maximum arrest force of 1800 lb is allowed.1.2.4 Suspension—Allows 0 free-fall distance while supporting the user’s weight.1.2.5 Fall Restriction—to prevent or limit free fall from a work position or while ascending/descending a wood pole.1.3 Three types of climbers, (Types A, B, and C) and two types of climber straps, Types (A and B) are covered.1.4 Two types of body belts, (Types A and B) are covered.1.5 Eight types of work positioning devices: three positioning straps, (Types A, B, and C), three adjustable-positioning lanyards, (Types A, B and C) and two nonadjustable positioning lanyards, (Types A and B) are covered.1.6 Two types of WPFRD, (Types A and AB) are covered.1.7 Arborist saddle, (Type A) Work Positioning and Suspension are covered.1.8 Two types of harnesses, (Types A and B) are covered.1.9 Two types of energy absorbing lanyards, (Types A and B) are covered.1.10 The values stated in United States customary units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.11 The following safety hazards caveat pertains only to the test method portions, 9.2, 10.3, 11.2, 14.1.4, 15.3, 15.4, 16.2, 17.2, 18.4, 21.2, 22, 23, and 25 of this standard: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.12 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
