Rules and Regs In Germany

[LampTramp]

Hi Blue Room!

First time asking a question so here goes!

I am working on a lighting plan at the moment for an opera season in an amphitheatre in Germany.

It's looking to be a full on LX Rig, having a chat to some collegues, it was mentioned that the Germans have guide lines on rigging and

what units should/can be used for an extended time in the open air.

As this is an opera season the gear could be outside for up to a month so, has anyone heard of the recomendations that they have, or where I should start looking.

There is no option for the equipment to be covered unless we go for movers in domes...

Any help would be cool.

Thanks
