A new set of effective, environmentally safe, nonflammable, low-toxicity refrigerants, solvents, foam blowing agents, propellants, and firefighting agents is disclosed. The agents are clean, electrically nonconductive, and have short atmospheric lifetimes, zero ozone-depletion potential, and low global warming potentials. The agents comprise at least one fluoroiodocarbon agent satisfying the general formula CaHbBrcCldFeIfNgOh, wherein a is between and including 1 and 8; b is between and including 0 and 2; c, d, g, and h are each between and including 0 and 1; e is between and including 1 and 18; and f is between and including 1 and 2, either neat or mixed with additives selected from the group consisting of: alcohols, esters, ethers, fluoroethers, hydrocarbons, hydrofluorocarbons, and perfluorocarbons.

A method of using a solvent to clean a surface of an article, comprising the steps of providing a solvent to an applicator, and applying the solvent from the applicator to a surface of an article to remove a contaminant from the article surface, wherein the solvent comprises a blend of at least one fluoroiodocarbon of the formula CnHbBrcCldFcIfNg, wherein a is between and including 1 and 8, b is between and including 0 and 2, c, d and g are each between and including 0 and 1, e is between and including 1 and 17, and f is between and including 1 and 2, with at least one additive selected from the group consisting of alcohols, esthers, ethers, fluoroethers, hydrocarbons, hydrofluorocarbons, ketones, and perfluorocarbons, the blend comprising 5 to 75 mol percent of the fluoroiodocarbon and 25 to 95 mol percent of the additive, and being nonflammable and electrically nondconductive, the fluoroiodocarbon having an ozone depletion potential less than 0.02 and a global warming potential less than that of chlorofluorocarbons, and the additive being nonreactive with the fluoroiodocarbon and not adversely affecting said properties of the fluoroiodocarbon, with the provision that when a is 1, the fluoroiodocarbon is selected from the group consisting of fluoroiodomethane, difluoroiodomethane, difluorodiiodomethane, bromodifluoroiodomethane and chlorodifluoroiodomethane.
