Some mistranslations are just amusing, while others could have rather more serious consequences.
I saw this on a hand drier in one of the toilets at UBD:
The advice to 'place your hands in and out of the machine' sounds potentially lethal!
In contrast, this advice elsewhere on the same notice is not quite so dangerous:
The trouble with this one is that 'hang down' is an intransitive verb – it cannot take an object, so, for example, you cannot *'hang down your clothes in the wardrobe'. In consequence, as 'things' cannot be the object of 'hang down', the instruction must be that you should not yourself hang down from the machine. I guess people are not really likely to try and do that!
