WARNING NOTICES REQUIRED?

[Brunel]

In the flats where I live, we have an electrical cupboard. It is where the main supplies enter the building.
We have a 415 Volt 3 phase supply plus all the usual fuse terminations etc.
All the electric meters are here as well.
It is just a large cupboard, with a door that can be locked.
Should the door be marked with any warning signs?

Thanks .

It isn't necessary but you can put one in place might be handy for the emergency services.
