Recent toxicity data on fluoroiodocarbons.

Type of article: Periodical article

Summary

Fluoroiodocarbons are suggested as replacements for CFCs and Halons in various situations. Toxicity data has raised unnecessary concerns because of inconsistency in presentation. Percentage by gas volume can differ widely from percentage by mass. Data for several fluoroiodocarbons is compared in common form with other materials. In firefighting there are no other candidates for a drop-in replacement to Halon 1301 than those containing trifluoromethyl iodide which is already approved for use in unoccupied areas. Tests indicate that when used in blends with hydrofluorocarbons, improvements can be made in cost, deliverability and toxicity. For refrigeration, trifluoromethyl iodide appears to be not worse than R123. It is reasonable for use as a foaming agent, and is safer than ethanol or 1,1,1-trichloroethane as a solvent. D.W.H.
