Is there a way to destroy water? End the cycle. No turning into any other element, just gone.

At work they tell us not to throw the cooling thermite (boutet process of welding rail) into water because the water will absorb heat, 970+ BTUs of heat, convert to steam, then separate into its two parts, and create a hydrogen explosion. 

 I don’t really understand the Hydrogen explosion bit, but that’s what they told me. I thought it was just a steam explosion from the rapid 1000x expansion of steam, but idk.   

Never done this because I don’t want to throw a grenade anywhere near myself.    

But the water doesn’t really go anywhere. It just makes a state change to steam. (And maybe undergoes a few quick chemical reactions from the sudden increase in temperature. Can heat of thermite really separate the Ha and Os like electrolysis?)

Please, scientifically literate people expand on this and educate me.
