Probably any commercial or government organization of any size or mandate to provide service 24/7 like a hospital still has backup ICE engines on site to provide power to continue operations in case of loss of power from commercial power sources. Doubtful if anybody positions those engines inside a populated building without a suitable exhaust system.
