In recent times in many countries there have been moves to increase safety through the use of safety harnesses.
They do not prevent but can arrest falls and are therefore seen necessary as the last resort.
As it is often only possible to attach the anchoring point at foot level, falls happen which can both harm and possibly kill.
And contrary to popular belief the majority of fatal falls occur below the height of 5m where harnesses are often ineffective.
Harnesses, by their nature also restrict movement, which not only slows down the work process but also in itself can be dangerous.
There are many scaffolders who owe their lives to the fact that they have been able to move quickly out of a position that suddenly has become life threatening.
Even while wearing a harness it is obvious that the Scaffolder is still in danger before the guardrails are in place while building, and after they are removed while dismantling.
