Rock scaling is usually the first approach to any slope work and it may be all that is needed to make a slope safe. Highly trained rock remediation technicians should be used for this type of work, especially when working near private or public utilities, infrastructure or buildings. Slopes should always be scaled from the top down. Manual rock scaling is performed on ropes. Rope access technicians use pry bars, inflatable air bags, air tools and nonexplosive rock breaking methods. Rope access technicians can bring down dangerous overhanging boulders, slabs and loose rock structures. Protection of structures, roads and utilities below the scaling area is the most important for planning for future scaling work sites. Manual scaling should be performed even on slopes that will be covered by drapes or pattern bolted in order to protect the rope access technicians during work on the slope. Loose rock can be dislodged during work activities and become extremely dangerous for the rope access technicians and can damage ropes and equipment.
