K.3.1.5 Descend carefully and slowly, controlling the speed of descent by means of the descending device, the precise method depending on the type of descending device used. Never lose control of the free end (the tail) of the working line leaving the descending device. Always lock the descending device to the working line during stops in the descent. Where the back-up device is used with a device lanyard, ensure it is managed so that there is minimum slack in the device lanyard.
