WORK POSITIONING and RESTRAINT

Diagram 2. EN 358: 2000 harness for work positioning and restraint

These attachment points are designed to either hold the user in position at the work-post (work in suspension: work positioning), or to prevent the worker from entering a zone where a fall is possible (leash

principle: travel restraint). These attachment points must only be used to attach to a restraint or work positioning system, maximum fall height: 0,5 m.

These attachment points are not designed for fall arrest use and it may be necessary to supplement work positioning or restraint systems with collective fall arrest systems (e.g. safety nets) or personal fall

arrest systems (e.g. an EN 363 fall arrest system).

When used in a fall arrest system in accordance with the EN 363 standard, use a TOP or TOP CROLL chest harness in conjunction with your seat harness.

Ventral attachment point

The EN 813: 1997 standard concerns seat harnesses that are used in work positioning,

restraint, and rope access systems when a low attachment point is necessary.

Use this ventral ring to attach a descender, positioning lanyards or progression

lanyards.

This attachment point should not be used to attach fall arrest systems.
