Authorities are blaming the huge explosion in Beirut on improperly stored ammonium nitrate fertilizer set off by an careless welder.
I once looked into using AM to open some ponds in the Louisiana marsh, and it had to be mixed with fuel oil about 1 part to 3 parts. And then you needed dynamite to set it off, so I am skeptical of that explanation.
On the videos, it looked a lot like a fuel/air explosion to me.
Anyone with an informed opinion?
