Ah, that makes sense. It's too bad they can't drill into it to relieve pressure without destroying the integrity of the tank (not that I'd want to be anywhere close to it either).

If they didn't have to worry about it imminently exploding I wonder if they could somehow wrap it with reinforcement (e.g., wrap some high strength metal around the tank to prevent it from deforming when drilled into) and then drill into it to extract the liquid?

One of my other less serious ideas was to helilift a Chernobyl style containment structure around it, but I imagine they don't have one of those just sitting around waiting to be used.

Wrapping metal around it sounds like one of those mythbusters episodes where they did not get as much shrapnel as they wanted.
