The climber will fall about the same height h in both cases, but they will be subjected to a greater force at position 1, due to the greater fall factor.. In lead climbing using a dynamic rope, the fall factor (f) is the ratio of the height (h) a climber falls before the climber's rope begins to stretch and the rope length (L) available to absorb the energy of the fall,
Fall history is the strongest risk factor associated with subsequent falls. [28] Older people who have experienced at least one fall in the last 6 months, or who believe that they may fall in the coming months, should be evaluated with the aim of reducing their risk of recurrent falls. [29]
The safe fall distance is a function of the fall factor and the deployment of the "energy absorbers". As a rule of thumb for a factor 2 fall, a fall distance of approx 6 m (20 ft) will be required. This is equivalent to 2 stories of a building. If the fall clearance is less than this the worker may strike the ground before his fall is arrested.
In any fall, the 'lead climber' will fall at least twice the distance of the runout (and sometimes more if the climbing rope has to flex, or if the belayer does not immediately grip the rope tight and lets more rope 'pay-out'). The greater the runout, the greater the total distance in any fall, and the greater the mental pressure on the climber.
The German company Edelrid introduced the first kernmantel rope in 1953, which revolutionized fall prevention. Hemp climbing rope became a thing of the past and rope breakage was greatly reduced. In 1964, Edelrid and Mammut [1] both developed dynamic ropes capable of withstanding multiple falls. These became the forerunner of the modern dynamic ...
The self-arrest is a climbing technique mostly used in mountaineering and alpine climbing where a climber who has fallen and is sliding uncontrollably down a snow or ice-covered slope 'arrests' their fall by themselves by using their ice axe and their crampons.
Rope access or industrial climbing or commercial climbing, is a form of work positioning, initially developed from techniques used in climbing and caving, which applies practical ropework to allow workers to access difficult-to-reach locations without the use of scaffolding, cradles or an aerial work platform.
Falling is the action of a person or animal losing stability and ending up in a lower position, often on the ground. It is the second-leading cause of accidental death worldwide and a major cause of personal injury, especially for the elderly. [4]
