Fire trucks

Last night, an unit around my apartment fired, i was wondering how it started.
I didn't hear any alarm rang, luckily that time still not too late, it was around 9 something, some people realize the incident happen so they were trying to shout loud to get all the residents went out from the building.

After awhile, the '1st' fire truck arrived and the fireman start to fight with the fire, just a few minutes the fire is under control already.

I know this is nothing worth to mention, but there are something more interesting to share about this incident.

After 10 minutes, there 2 more fire trucks came at the same time, then after about 10 minutes again, the 4th fire truck arrived, I was wondering why so many fire trucks come but there just only one room get fire, so I just went in to my house for about half an hour, when I came out again, there already 5 fire trucks here. See, how helpful is our Malaysia Bomba. No lah, just a praise to them only, I think because too many people report at the same time, so the efficient call-centre abit messy lo.
