Nothing like designing for 300% of volume. Also no way to prevent foam from pouring into the unaffected portion of the bldg. probably resulting in the second explosion. Design fail on multiple accounts.
The news clip didn’t reveal the open walled enclosure. It looked like a building with foam coming across the roof which made no sense. Here is another video from a drone, you can see the foam in the adjacent area where there was no initial event. https://www.youtube.com/watch?v=AH5W-BW0w2k Craig L.
