If you have a high rise or respond on mutual aid to a high rise district, do you know if they are marked for floor identification? If so, do you know how they corresspond with the interior labels? High rise buildings are marked differently, if at all. In our area the windows are typically marked with a reflective sticker, one on every fifth floor. Where this gets tricky is when the interior floors are labeled differently.
This high rise has red circle on the corner on the fifth floor window and the 15th floor window. You can see them in the top right hand corner of the windows on the right side. Now, some places will actually put numbers on the windows, but we are going to just address this one method. If you count the windows you will notice that it doesn't add up.
This building has eliminated the 13th floor, thus making the floors on floor off if counting. This is where preplanning comes in.
It is important to know how the outside corresponds with the interior. In some of these buildings the ground floor may be labeled as "Ground" or "Lobby" and not the first floor. In addition, if there are penthouse units at the top they may be labeled as such and not given a numerical label on the elevator panel. On this building the 13th floor has been eliminated. It goes from floor 12 to 14. On the photo below you can see that there is no 13 on the panel.
We need to get into these buildings and be familiar with the labeling of floors. The last we want to do is deploy to the wrong floor or take an elevator to close to the fire floor. It is also important when searching for victims, knowing what floor is reported and how the occupants will report floor numbers.
This is by no means the only marking systems, just one method. Get out, know your system and train with it.
