I happen to be a big yellow bananna. One of the biggest problems in fires are children. For two reasons one that kids don't wake up, the voice detectors are supposed to work, although the detectors that I have also seen work are "horns and strobs". This brings us to another problem kids will often hide when scared, and they find the smallest hiding spots. I fire I was recently in a kid was hiding on a shelf in a closet. He wasn't going to come out for the big thing sounding like Darth. If it wasn't for the Thermal Imaging Cam I would have ever found the kid.
Please if you have kids please get them around fire fighters in gear, the give the loud breathing bananna a hug is great. Also find escape routes, at least three, and go over them with your children. Lastly if you can make sure your bedroom is on the same floor as the kids, at least young kids.

Sorry for the long rant
