To provide an industrially and environmentally more preferable nonflammable liquid composition having a fluorine compound reduced, as compared to previously known nonflammable liquid compositions.

A liquid composition is used, which includes a flammable liquid and a fluoroiodoalkane represented by the following formula (1):

##STR00001##

(in the formula, X each independently represents H or F, and n represents an integer of from 0 to 5), and which is characterized in that the total amount of the above-mentioned flammable liquid and the above-mentioned fluoroiodoalkane is from 95 to 100 wt % of the entire amount of the above-mentioned liquid composition.
