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.
Anchor point requirements
EN The anchor point shall be able to sustain a minimum load of 12 kN (2700 lbs). Refer
to EN 795:2012 or CEN/TS 16415:2013.
ANSI The anchor point shall be able to sustain a minimum certified load of 3600 lbs
(16 kN) or 5000 lbs (22.2 kN) in the absence of certification. Refer to ANSI Z359.14-
2012 CLASS B.
CSA The anchor point shall be able to sustain a minimum load of 5000 lbs (22.2 kN).
Refer to CSA Z259.15 CSA Z259.13, CSA Z259.15
Note: If multiple fall arrest systems are attached to the same anchor point the strength
requirement shall be multiplied by the number of personal fall arrest systems.
Lanyard
Always use an energy absorbing lanyard or retractable type fall arrestor that complies with the
relevant standards within the country of use. In some harness variants, side attachment points are
included. These attachments are only to be used for a suitable work positioning lanyard.
