"Sprinklers and alarms don't work"... "Even the popping sound."

[Anchor]
While the investigation by police and fire authorities remains to be seen a little longer, some guests said their sprinklers or fire alarms were not working when the fire broke out today.

Witnesses also said there was a big fire when they heard a 'pop' explosion.
Let's continue with the interview of rescuers and witnesses

[Ansan shopping mall fire rescuer: (Like a fire alarm)]It didn't ring. (What about sprinklers?)) I didn't. The smoke kept coming in, and everyone in the other room couldn't breathe, so they coughed a lot, and the next room was swearing, screaming, and getting angry, so they broke all the glass....]

[Ansan shopping mall fire scene witness: At first, I heard a loud explosion and checked, and the fire started really loud outside. The explosion sound is like three times at first? It wasn't very loud. I think it's because I'm in the store now. I didn't know what it was at first.]
