A safety device 2 for use in a fall arrest or safety system comprises an energy absorber which is a resilient element (such as a tolerance ring 4) providing an interference fit between first and second components of the device. The first and second components may be a shaft 5 and a safety line drum 3. In the event of a fall the first and second components effect movement relative to one another, the interference fit being overcome, and the tolerance ring 4 acts to resist the relative movement thereby absorbing energy. |
