In a rope access system, the worker moves along a work rope.
The ASAP is installed on a safety rope and connected to the A (fall arrest) attachment point of the harness. Its role is to arrest the fall in case the primary belay or positioning system fails.
Under the EN 12841 standard, the ASAP certification was conducted using only EN 1891 type A semi-static kernmantel ropes. The rope diameter that is compatible with each ASAP model is specified in the Instructions for Use for the device.
The use of other ropes has not been tested, and thus falls under the responsibility of the user.
