What is the building type? Industry? location? Building age? Number of persons? Surrounding industry? Surrounding buildings? Handicap access? Handicapped residents? Level of training on hand? EMT? HazMat? Fire Suppression???????

The correct level of preparedness for a factory is vastly different than that for a bio-tech lab wich is different than that needed for a single story office building with software geeks within which is different than that needed for a High-rise office with a Data-Center housing a Mainframe and other Electronics posing a fire hazard.........

It's easy to say you need

1) FAK
2) ToolBox
3) Flashlight

but if you are in an old building with "historic" fire systems you might want a large Fire Extinguisher on the wall at every corner. If you are in a building that also houses some industry dealing with bio - chem hazmat stuff you might want to look into modifications to the ventilation systems to provide for positive pressure containment.

Provide some details and we can get this ball rolling! I'm sure that there a bunch of helpful suggestions just waiting to land once we know the target.
