[Chapter 2] Section 5

1. Measures for moving up and down and passing through, etc., and use of peripheral equipment

(1)Fall arrest equipment is mandatory during work. Passing through and moving up and down (including the case of moving up and down while confirming the soundness, etc. of equipment for moving up and down.) are fundamentally different concepts from work.
If it is extremely difficult to use fall arrest equipment, such as when there is no place to attach the hook, etc. of the fall arrest equipment (as when tree trimming, etc.) then alternative measures such as wearing a safety helmet must be taken.

(2)A fall arrest function is not required when moving up and down using a vertical main rope, safety block, or vertical rail. In addition, when directly linking between the connector provided on the chest, etc. of the full harness type and a vertical main rope, safety block, or vertical rail, via a subrope and slide-type device for fall arrest, as recognized by ISO standards, the pertinent subrope and slide-type device for fall arrest fall within the scope of the lanyard of the full harness type among the types whose safety can be confirmed through appropriate fall testing, etc.

(3)Movement ropes used in construction work, etc. on power transmission towers are not lanyards, and are treated as main ropes.
Also, if the movement rope and the full harness type are directly linked to each other with key-lock type safety device, etc., and the movement rope is equipped with a shock absorber, the key-lock type safety device, etc., falls within the scope of the lanyard of the full harness type.
In this case, the shock absorber of the movement rope has a function conforming to a Type 2 shock absorber.
