In the factory, they sometimes seem to just explode randomly when the pieces next to them are just fine. It might be some anomaly of how they got quenched and/or temperature changes, though. I remember it mostly happening in winter for whatever reason, so maybe a cold breeze got them? There's probably quite a contrast between the furnace and the cold air coming in around the loading docks.
