This isn't an easy accident to dissect. I don't think anybody has the answer yet.

Ordinarily, violations occur on a regular basis. On any inspection, you'll find some. This is not a very huge mine. As the numbers grow in volume, it's something management has to address.

To deal with the problem, it takes manpower and constraints on the production track.

There's a lot of questions we can't answer yet, because we don't know. We just don't know.

Mark my words, my friends: Tom was here before the river and the trees; Tom remembers the first raindrop and the first acorn. He made paths before the Big People, and saw the little People arriving. He was here before the Kings and the graves and the Barrow-wights. When the Elves passed westward, Tom was here already, before the seas were bent. He knew the dark under the stars when it was fearless - before the Dark Lord came from Outside.

It's probably the most vulnerable part of this whole equation. We don't have an easy answer for this,
