retracting lifeline to the designated tie point

Fall Protection Equipment
(not provided)
Safety Devices
1-
Attach a rope to a self-retracting lifeline hook for easy retrieval from base level.
2-
Using the designated tie point (fi g. 2.5) on the motorized unit, secure the fall protection
equipment. Tie points are designed to resist to a maximum arrest force of 5000 lb (2268 kg)
and can be used by workers to tie themselves to the unit (not more than one worker per
tie
point).
3-
Attach the body harness to the self-retracting lifeline before climbing or descending the
mast.
When climbing or descending the mast
The use of fall protection equipment is
recommended
when climbing or descending
the mast when the height of lift is over 10' (3 m) above base level and is
mandatory
for
climbing or descending the mast when the height of lift is between 30' and 69' (9 m and
21 m). It is not recommended to climb or descend the mast when the setup is at heights
over 69' (21 m) because of the time and effort required to reach such heights. The use
of alternate equipment compliant with local regulations, such as a rapid mast climber, a
transport platform system, or a conventional scaffold stair system will prove to be more
effi cient. Refer to local regulations for more information.
Cross-arm anchorage strap
(not manufactured by Hydro Mobile)
Fall arrest bracket
When moving planks
1-
Using the designated tie point (fi g. 2.5) on the motorized unit, an optional fall arrest
bracket installed on two guardrails (fi g. 2.8) or a cross-arm anchorage strap tied to
two guardrails (fi g. 2.9), secure the fall protection equipment. Tie points are designed
to resist to a maximum arrest force of 5000 lb (2268 kg) and can be used by workers to
tie themselves to the unit (not more than one worker per tie point).
2-
Move planks in front of each mast to pass a tie level or modify the planking confi guration.
The use of fall protection equipment is
mandatory
when moving planks – for example,
when moving planks away from in front of the masts to pass a tie level or to modify the
planking confi guration.
