Yes it means danger, ridiculously long web link ahead....:-)

Sorry, Brian. I couldn't find a way to shorten it.

The icon is roughly square, with a diagonal line from bottom left to top
right, dividing it into two halves. In the top left segment there is a
symbol of sun with "rays" radiating from it. The bottom right segment is all
black, like an arrow head pointing south-east.

It symbolises a solar farm - and indeed on the satellite photo on Google,
there are rows of the solar panels covering a large area. It is situated
between two motorways (M49 that goes over Severn Bridge, and M5 from Exeter
to Birmingham) north west of Bristol, in a fairly insalubrious area of
sewage works, industrial estates and trading estates, close to the Severn
Estuary.
