Abstract
Disclosed is a composition, a fire extinguishing device, and a use thereof, which can be applied to a product or element with a possibility of heat generation, ignition, and/or explosion during drive, storage, and/or maintenance processes to effectively respond to the heat generation, ignition, and/or explosion. The composition is substantially non-flammable and non-toxic.

A composition comprising:
- a solvent having a freezing point of −10° C. or more under 1 atm;
- and
- ionic compounds having a solubility of 75 g or more in 100 g of water at 25° C., and being non-flammable or having a flash point of 120° C. or more,
- wherein ΔT1 is in a range of 5 to 40, and a ratio ΔT2/ΔT1, is 0.4 or more, ΔT1 satisfying the following Equation 1 and ΔT2 satisfying the following Equation 2:
