    Was also thinking of the guy in the small truck which scooted in front at 1:05. At 1:20, the shop floor turned into the surface of an active volcano. So much for the quiet chat he was having with a co-worker!

    I noticed the driver was out of the vehicle before it came to a complete stop. Shop floor safety may not be Job Number One here. Maybe a 20/20 hindsight observation, too, but walking the floor below the surface level of a vessel of molten metal seems not Best Practice from the git go.

    What, exactly, was the vessel sitting on the platform supposed to do when the crane operator was tugging on it laterally? I'm assuming not that.

    It looked to me as if he was lowering the yoke to horizontal so further lowering of the crane hook would disengage the hook from the yoke. He didn't get it low enough and as he moved the crane laterally the hook was still pulling on the now horizontal yoke and that tipped the crucible.

    At 30-45 seconds, a guy walks out and does something on each side of the crucible where the yoke is attached. I was assuming they were supposed to disconnect the yoke. It appears there are moulds off to the right, possibly to make ingots. As Marv mentioned the crane operator was not attentive enough.

    Clean up on aisle #4 ...
