A propane tank by itself has no explosive force. Propane will only burn when mixed with oxygen. However you can create what they call a BLEVE from a propane tank (boiling liquid expanding vapor explosion). Basically you would heat up the propane tank (example house on fire, etc) and a reaction would occur causeing the tank to burst. There are other ways to do it but it gets really technical. Research BLEVE and you will fand many references about blast effects and fireball radius, frag radius etc. The following link gives you safe separation distances:

A 20-pound propane tank typically contains about 4.7 gallons of propane, which is equivalent to about 90,630 BTUs. This is enough energy to create a significant explosion if the tank were to rupture and ignite, potentially causing damage in the surrounding area.
