Abstract
The safety structure comprises temporarily deployable safety bars that can be attached to a support member associated with at least one of a wind turbine hub, a wind turbine blade, a wind turbine root section, a wind turbine yaw mechanism, a wind turbine tower base, a wind turbine foundation, and a wind turbine nacelle. The bars can be coupled with each other and the structure may comprise at least one inflatable portion. The safety bars are first attached to the support member surrounding a wind turbine portion and then coupled to each other defining a fence structure.
