7.3 Escape route

0011461408

It is intended that the service crane hatch in the rear end of the nacelle can be used for escape.
For escape through the hatch, the use of a descent device is necessary.

It is also possible to escape through the hatches in the spinner cover.

There is one descent device in the nacelle. A descent device can lower one or two people at the
same time. It is recommended to have 1 descent device for every 2 persons working in the
nacelle. If more than two people are present, more descent devices should be available, (that is,
additional descent devices should be brought to the wind turbine).
