One of possible ways to reduce the volume of the use of hydrofluorocarbons (HFCs) as gaseous fire suppressants is studied in the paper. Extinguishing mixtures of HFCs and some fluoroiodocarbons are investigated. It is theoretically predicted that fluoroiodohydrocarbons are effective inhibitors of conversion of fluorinated alkanes in a flame. Special experimental equipment allowing to measure fire extinguishing concentration of gaseous fire suppressant having high boiling point is described. Experiments show that fluoroiodohydrocarbons are effective means of reducing the use of gaseous fire extinguishing agents based on fluorinated alkanes, which are greenhouse gases: in the presence of insignificant addition of iodized substance the volume of fluorinated alkanes required for the extinguishing decreases several times. Creation of mixtures with the content of iodized components higher than 5 mass. is impractical because in this case the iodine-containing substance will exceed safe level of its use from the point of view of toxicity
