EVAC the building and do the urban renewal method, surround and protect the exposures. The picture says it all. To search the building will take to long and you will need 50 FF just for that. It will take 50 more to protect exposures for at least 36 hours maybe. If you showed up with 6, go to people first and get them moved away and to safety.
