of supporting the worker. For rescue purposes,
the anchorage point must support a minimum
of 3,100 lbs. (13.8 kN) per attached worker.
Consult local, state, federal and provincial
regulations as revisions occur.
3.2.1 Every anchorage point must be selected with
care. Make sure that there are no obstacles in
the evacuation path and on the landing zone.
Maintain a safe distance from any obstruction
to ensure a safe descent (e.g. electric wires,
glass, concrete reinforcing bars) (
Figure 7
).
3.2.2 Never use an anchorage point which will not
allow the connector keeper to close. Anchor
must be compatible with connector and
must not be capable of causing a load to be
applied to connector keeper. Before each use,
ensure that all connectors are in good working
condition and safely closed, especially the
gates on the snap hook and/or carabiner.
