    $\begingroup$ I'd say many would do better then water, for they evaporate easier and choke the flame with their vapors. We still use water because it is cheap and environment friendly. $\endgroup$ – Ivan Neretin Nov 24 '16 at 5:26

Carbon tetrachloride was once used for this purpose as it has practically no flammability at lower temperatures .
