A survivor who's house collapsed in the explosion has told us what he experienced during the terrifying industrial accident.
"I woke up as I smelled gas just before the explosion happened. I was sure it was gas. My mother asked me if I wanted to go outside and see what the smell was. That's when I heard a big bang. Then, my house started to collapse. I found it difficult to breathe. Then I saw a light flashed by. I scrambled from my home. I could see vehicles destroyed and some workers hurt.
