For fixed grounded equipment I believe the relevant standard for leakage current ("touch current") is IEC 60950-1 and allows up to 3.5mA.

Whether that is safe or not depends on further details we are lacking.

As you said this, yeah. Looks like some extremely outdated garbage even with no recess for a plug, not to say earth connection. I don't think anything like this can be possibly legal these days. Electrician most likely won't be able to do anything with this as cable in the wall most likely does not contain an earth conductor. And therefore cannot be fixed without doing total rewiring.

On other thought I googled for Danish plug and it uses an earth prong unlike a usual Schuko socket. However plug in the video seems to be a usual Schuko. Therefore socket may actually have an earth contact but a wrong plug was used so there is no earth connection.

I think what we're looking at is one of these on the right:


Conveniently takes a CEE 7/4, 7/6, or 7/7 while providing no earth contact. There's a reason I regard that entire series as a fatal mistake.

lots of stuff doesn't have or need earth, as long as you only use Danish plugs in Danish sockets something that has a ground pin won't fit in a socket without ground

Unfortunately, lots of equipment comes with non-Danish plugs, does not have an earth pin, and will fit readily into those sockets.

This is also not the only scenario in which the CEE 7 series allows a dangerous combination. But it will happily prevent you plugging a non-earthed plug into an earthed socket!
