I can't speak for Sweden but living in Ireland every time I've gone to a museum and wanted to handle something I would generally just ask a passing worker "Hey could I maybe get a closer look at that?" and depending on what the item is they'd either just pop the case open, fetch a pair of gloves and take me to a back room, or politely refuse.

Hes not just reaching into display cases and trying on age old artifacts.
The things he's putting on are the replicas put out specifically for the public to try on. Hence some of them being chained to tables and what not so people don't walk away with them.
A lot of museums do this so that people who come through can get a feel for what they're seeing instead of just looking through glass boxes.
