Yep, there it is. Wall collapsed and pinned the guy on the wall knee deep or so. You can see his boots in the hole they dug him out of.
Need wall plates below 5-6 ft depth IIRC.
I have violated this rule in a *much* deeper trench in the middle of winter in Wyoming -riding in the bucket down 15 ft it so to inspect archaeology in the walls - I was young & stupid.
@FireMonkey Trenches are treacherous and proper shoring is a lifesaver! Glad they got the guy out, hope they're OK.
