Removing a dangerous item

I have a question concernig dangerous items. Next to my house there is a broken cardboard box lying on the ground. I wanted to drive over it in a car, so I decided to check whether it’s empty. This is a box that’s completely broken and folded, and it’s lying on the ground in two layers. There is one place where there are three layers, and this is the part that I lifted up to check if there’s anything inside; I only lifted up the top layer. Now, my question is: is this box considered a “hole” (“bor”), since this can potentially cause damage (maybe it’s slippery)? Is it possible that when I lifted up the box, I lifted it more than three handbreadths (about a foot), and thus acquired it? Does that make me responsible for it? I must state, that when I lifted a part of this box, it remained attached to the box, and most of the box remained on the ground. So, maybe this is not considered lifting the box at all?     

You did not acquire the box. However, whenever you find in a public domain an item that’s considered a “bor”, that is, an item that could potentially cause damage, you should remove it, to prevent others from being endangered by this item.
