Thought you may like some pics of trenches, and why trench boxes are required. At Dulles, we enforced VERY heavily the use of trench boxes in ANY trench over 3' deep. The only reason to step outside one was to pick up that last paycheck, cause if you stepped out, it would be your last. We did have a tunnel collapse while I was there, a bit different than a trench cave in, but a life was lost none the less.
You can see the type of soil we were dealing with, called fractured, or degraded rock. I've had people argue it was Class A soil just after they dug the hole, while we were arguing, the wall would collapse, END of argument.
