Personal fall-arrest systems — Part 4: Vertical rails and vertical lifelines incorporating a sliding-type fall arrester

This part of ISO 10333 specifies requirements, test methods, instructions for use and maintenance, marking, labelling and packaging, as appropriate, for vertical rails and vertical lifelines which incorporate a sliding-type fall arrester.

When connected to a full-body harness as specified in ISO 10333-1, vertical rails and vertical lifelines which incorporate a sliding-type fall arrester constitute a personal fall-arrest system (PFAS), which will be specified in a future International Standard.

Vertical rails and vertical lifelines which incorporate a sliding-type fall arrester in accordance with this part of ISO 10333 are limited to use by a single person of total mass not exceeding 100 kg.

NOTE 1 Users of PFAS whose total mass (which includes attached tools and equipment) exceeds 100 kg are advised to seek advice from the equipment manufacturers regarding the suitability of the equipment, which may need additional testing.

NOTE 2 PFAS using vertical rails and permanent vertical lifelines inherently limit the user's horizontal movement, whereas PFAS using a temporary vertical lifeline permit significant horizontal movement by the user. Special notice should be given to the req
