Container of waterfalls goes boom in a BIG way!

We do a lot of disposal but this takes the cake. A 20 ft container with 441 cases of waterfalls totalling 8661 Kg NEQ (net explosive quantity) We tend to think of waterfalls as being a rather benign firework as it doesn’t go anywhere, it just cascades and looks pretty, it doesn’t explode etc. But in large quantities the mass is becomes quite dense with little airspace and is benign no longer!
