While working in the upper reaches of the tower, rescue can be almost impossible from the ground by conventional methods. Self rescue, personal evacuation and easy to use casualty evacuation equipment is a necessity for personnel working on wind turbines.
- The essence of evacuation or rescue is speed. Rapid descent, available for multiple users in the event of fire or complete mechanical failure is an absolute must for personnel constructing or maintaining the wind turbine.
- Self rescue and casualty evacuation could be needed at any point along the tower, including the Nacelle at the top.
- All rescue and evacuation equipment should be quick and easy to use. Non-installed, or temporary equipment will need to be lightweight and quick to use in relatively confined areas.
