"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 with the rescuers who were staying at the time of
and witnesses to the fire scene.

[An Seong-jun / Guest at the time of the fire: I woke up to smell of burning while sleeping, and the room was already smoky. (Did the fire alarm go off?) Oh, I didn't hear that. I can't even hear the alarm. I woke up in my sleep because of the smell of smoke and burning. (So, did the sprinklers not work either?) No, not at all. Alarm sounds, sprinklers, and things like that....]

[Witness to the scene of the fire: First, I heard a loud explosion and checked it out, 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.]
