The US Chemical Safety Board (USCSB) recently released a video describing the refinery explosion in Superior WI in which a large HF release nearly happened. This resulted in the evacuation of 25 thousand residents in an area about 24 miles downwind from the refinery. (Think how many people are within that distance of the Torrance Refinery).
Again, the accident occurred because the operators did not take into consideration all the possible scenarios. And we can see the consequences.
