Did firefighters make West, Texas, fertilizer plant fire worse?

Breitbart.com’s Brandon Darby is in West, Texas, after a fertilizer plant explosion yesterday evening.

According to Darby, first responders sprayed water on the fire, likely making the fire worse.

I did use facts. That's the error they made. Explosion likely would've occurred anyways, but they used water. @PumpJackSally

A flight medic on the scene. Now you're both blocked. "RT @featherchick @brandondarby @PumpJackSally Cite source who told you used water?"

The first responders were likely volunteers and did not know to use avoid water on plant. @Researchagain

As far as we know, this still hasn’t been confirmed by local officials, but others are hearing the same thing:

“It was a small fire and then water got sprayed on the ammonium nitrate, and it exploded just like the Oklahoma City bomb,” said Jason Shelton, a clerk at the Czech Best Western Hotel in West.

According to CDC, one should never direct water straight at anhydrous ammonia http://t.co/E4w9FB8rMw #westexplosion
