Pre-use checks and requirements
Risk assessment and rescue planning
The Latchways PRD forms part of a fall protection system and it is
therefore recommended that before undertaking work at height and
at regular intervals during the period of work, a risk assessment is
carried out. The risk assessment should cover, but is not limited
to, descent height, descent path, suitability of landing areas,
unprotected edges and rescue.
A rescue plan shall be in place to deal with any emergency that may
arise.
The Latchways PRD is designed, primarily, as a self-rescue system
and will assist with rescue planning. In the event that the User is
unable to initiate self-rescue a secondary release means is provided
on the right-hand shoulder area. This is a red and black rubberised
loop (figure 3a) which can be pulled by a Rescuer, by hand or
with the aid of the Latchways PRD Rescue Pole (figure 3b) or by
other means, to activate the descent. A telescopic pole assembly
is available (Latchways part number 68099-00) for this purpose.
Secondary release by a Rescuer should be taken into account in the
risk assessment.
