If you connect via stripped wire, fork or ring tongues, the banana plugs are bare on the top. You can stick two fingers in them. If you connect via banana jacks, the termination becomes safer.
I recall the banana plugs from previous versions shipped with plastic inserts that would prevent probing fingers. Of course those inserts can always be popped off quite easily.
Banana jacks are safer but not completely safe. Someone can come along, pull them out and contact them. A locking banana may be the answer (see link). https://www.nbhifi.nz/product/1649707
