  • the invention provides a self inactivating aerosol according to the third or fourth aspect wherein the nature and concentration of the antagonist is selected, or means are provided, to ensure that the time required for the antagonist to render the biocide ineffective is longer than the time required for the decontamination agent to be effective to render the contaminant harmless or reducing its ability to cause harm.

  • Another means of reducing the potency of many contaminants which are in the form of very fine particles is to flocculate them so the nebulising of a flocculant could significantly reduce the ability of the contaminant to cause harm.
