When Scaffolding is Needed The very short answer is: when a risk assessment outlines it is necessary! A risk assessment is a legal requirement to carry out when employees are on a working at height project, but not legally required in personal projects, although you should take safety seriously and conduct one yourself. Six randomly distributed broken wires in one rope lay or three broken wires in one strand in one rope lay.
