Big tanks DO blow out from their ends.  This BLEVE (Boiling Liquid 
Expanding Vapor Explosion) occurs when the "safety valve or pressure 
relief valve" malfunctions, and won't allow pressure building up in the 
tank escape, or escape fast enough.

As far as the tank's proximity to the ground rods, do yourself a favor:  
Ask the company who will install, fill, maintain this tank what you 
should or shouldn't do..  You'll sleep better at night knowing you did 
the right thing.  If no joy, email me direct, I'll try to get some 
research to you through NFPA..
