Check the swivel too, not just the latch. Had a hook spin on me once when the load shifted, and the latch popped open from the twist. Now I give it a tug and a quick visual on the whole assembly.
Tugging the latch is a smart move. It only takes a second to make sure everything is secure, and it can prevent a bad accident. I've seen gear fail when people skip that simple check. Little habits like that make the whole work area safer. Plus, it becomes automatic after a while, so you don't even have to think about it.
