(1) If a personal fall protection system for climbing activities is used, it shall permit the employee who uses the system to ascend or descend without continually having to hold, push, or pull any part of the system, leaving both hands free for climbing.
(2) The connection between a carrier or lifeline and the point of attachment to a body belt or harness shall not be more than 9 inches (23 cm) in length.
(3) A personal fall protection system for climbing activities shall be activated within 2 feet (.61 m) after a fall occurs in order to limit the descending velocity of an employee to 7 feet/sec (2.1 m/sec) or less.
(4) Mountings for rigid carriers shall be attached to each end of the carrier and shall have intermediate mountings, as necessary, spaced along the entire length of the carrier to provide the strength necessary to stop employee falls.
(5) Mountings for flexible carriers shall be attached at each end of the carrier. When the system is exposed to wind, cable guides that utilize a flexible carrier shall be installed at a minimum spacing of 25 feet (7.6 m) and a maximum spacing of 40 feet (12.2 m) along the entire length of the carrier to prevent wind damage to the system.
(6) The design and installation of mountings and cable guides shall not reduce the design strength of the ladder.
(7) Ladder safety devices and their support systems shall be capable of withstanding, without failure, a drop test that consists of an 18-inch (.41 m) drop of a 500-pound (226 kg) weight.
(8) All other personal fall protection systems for climbing activities shall be capable of withstanding, without failure, a drop test that consists of a 4-foot (1.2 m) drop of a 250-pound (113 kg) weight.
