Foam -That floats over the solvents and spreads quickly over it to seal off the oxygen supply
Caron dioxide -That displace the oxygen from the scene of fire and extinguish the fire by smothering
Dry chemical powder - propelled by a non-combustible gas, it forms a chemical powder cloud over fire and interrupts the chemical chain reaction and also cuts off the oxygen supply. Fire may rekindle as it does not adequately cool the fire.
Water mist - Though water cannot be used as it is denser than solvent, water mist of particle size about 400 microns are effective. It extinguishes the fire by cooling.
