Use
The ISC Rocker is a multi-use rope access and technical rope rescue back-up device. Examples of its potential
uses are:
• Back-up device in a twin line rope access type
system
• Fall arrester on a vertical flexible line
• Rope adjustment in a work restraint system
• Rope grab in a hauling or tensioning system
It is the user's responsibility to ensure that any items of PPE or other equipment used with the Rocker are
compatible and do not interfere with the safe function of any other component. Any item of equipment used must
comply to the relevant standard(s).
Note:
The information in this guide meets the requirements of the EU PPE Regulation 2016/425 . It is not comprehensive
and cannot be substituted for the correct training, which can be provided if required. If in any doubt, contact ISC
using the supplied information.
Do not alter or repair the product in any way.
Any component subjected to a dynamic loading should be examined and discarded if there is any sign of defect,
or any doubts about its safety.
Safety
The safety provided by the Rocker is dependant on the scenario, the anchors used and the skill of the user. The
strength and suitability will be reduced through factors such as, but not limited to, age, wear & tear, abrasion, cuts,
high impact loads, tight/sharp edges, knots, some chemicals (e.g. strong alkalis), UV exposure, environment (damp
or icy conditions), failure to store & maintain as recommended, etc.
The Rocker will perform differently when used outside of normal climatic conditions.
The user should keep any fall factor and lanyard length to a minimum at all times.
An appropriate connection method must always be used between the harness and the anchor or system.
The user must consult the instructions for any other components used in a fall protection or fall arrest system and
must pay attention to information including fall clearance distances, etc.
When used under the EN358:2018 Standard, this device must not be used for fall arrest, however, it is specifically
designed for fall arrest under the EN12841:2006 and EN353-2:2002 Standards.
Fall clearance distance = 2x length of lanyard (FF2) + height of operative + slip (max 0.75m) + rope elongation +
safety factor (1.0m)
A rescue plan should always be in place prior to any work at height.
