only.
Activating self-rescue
During a descent it may be possible to land on a lower part of a structure, this is not recommended
as it may cause slack in the system and provided potential for a secondary fall.
• Following a descent, internal components of the Latchways PRD descender device may become
hot. Allow to cool before opening the backpack.
• After a descent, the Latchways PRD descender device must be withdrawn from service and
details recorded on the periodic examination log.
Periodic examination
The Latchways PRD descender device is a key component in an emergency rescue plan. To
assess functionality periodic examinations shall be completed at least every 12 months, from
the date of first use, in accordance with MSA instructions. Local requirements, environmental
conditions or frequency of use can dictate more frequent examination. The periodic examination
shall be recorded in the periodic examination log. Harnesses shall be examined in accordance
with the manufacturers' instructions.
Periodic examination instructions, P/N 68201-97PE, may be downloaded from MSAsafety.com.
The service life of the Latchways PRD descender device, based upon its textile elements, has
been evaluated to be up to 10 years. Factors such as (but not limited to): environmental conditions
(eg contact with chemicals, exposure to temperatures >140ºF (>60ºC), incorrect storage and
frequency of use may reduce the service life.
Basic cleaning, storage and transportation
To remove light soiling the Latchways PRD descender device exterior may be cleaned, with warm water
(max 40°C /100°F) and pure soap or a mild detergent. Care should be taken to a avoid getting soap
or detergent into adjuster and quick release buckles. After cleaning, rinse thoroughly with fresh clean
water then remove excess water with a dry cloth. Allow to dry naturally, away from direct heat, then
examine fully before storing or returning to use.
