Mr Ashraf had been checking the building an hour before he was due to finish his shift, when he smelled fumes, said the 26-year-old, who works every Friday and Saturday night at the firm.
"It was really bad, I had popped my head outside and smelled it there too, then it was difficult to tell if the smell was coming from inside or outside the building."
Within seconds he was felled by the force of the explosion.
After he escaped two men from a nearby firm came to his aid and took him to their cabin, he said.
"It was awful, it was like we were in hell. The flames were 200ft high. We could see them growing."
"One minute everything is fine, the next minute everything just crumbled, and you really don't know what's happened, what's going to happen and you just try, you're hoping it's a nightmare and you're going to wake up out of it."
