Tripping and Sliding Around
If a liquid spills on the floor or there's some item of outerwear lying around, someone could end up as the stick figure in the very right picture. What if the person was holding a scissors, or even worse, a knife? They'd probably not end up in the best condition. They could hit their head on the edge of the table or tumble into someone holding something dangerous. That something "dangerous" could be a sharp item or a chemical that's bad for you. Neither would be very nice to land on, right?
