It’s a standard casement window, just with a weird aspect ratio. If you twisted the handle a different way it would only crack open from the top, letting you vent the room.
I live in a ranch style house on a completely flat property, there are no steps on it. Golden showers don’t come raining from above when there’s no above.
In our neighbourhood it was customary to celebrate Christmas on the open balcony of one of the high-rises. Children would climb to the highest floor and set off fireworks from the balcony. The railing was high, but the danger was still present.
They mounted a wrong window type. You can get one that doesn’t open fully, from the bottom edge. Usually they are mounted in corpo buildings due to liability issues
