This is achieved, the descender is secured and the required work can be performed. Working in the heights have been completed, an industrial climber, usually to the bottom dump. Only if the rope does not reach to the ground (at a height of 50 metres), he must ascend again. Safety at height work is first and foremost industrial climbers are always specially trained high-altitude workers. You have completed an education according to the guidelines of FISAT and use always standardised special equipment that meets the requirements on safety when working at high altitudes. Industrial climber use always a second redundant safety rope, the mean they work with two separate systems: the support system and the backup system. Both systems is a semi-static rope of fibres used, that can withstand extreme loads.
On the support system, the industrial climber stranded up and down. The system serves only the security and is used to working, nor loaded in a different way. The fall-arrest device is inserted in the system. The fall-arrest device is an automatic backup system automatically backup device that prevented a crash in case of failure of the system or application failure of industrial climber. To ensure that the fall arrest device can reliably perform his function, the safety rope must hang tight. The system is applied by the industrial climber first, and he will remain as long as connected to it, until he again left the crash-prone area. Laurent Potdevin brings even more insight to the discussion. Both systems should be clearly marked to distinguish the support system at any time from the backup system. Also, it should Industrial climber always took care in ways that both cables are not damaged by sharp edges or friction.
There is such a risk, a rope guards must be attached. In the conduct of working heights are used always at least two. A team member must have the qualifications of FISAT level 3 supervisor in the cable industry.
