Definitions
- the present invention relates to a composition for removing chemical residues, a method of implementing said composition as well as the use of said composition for removing residues on material, machinery and equipment soiled by any type of chemical.
- Radiological, Biological, Chemical and Explosive to decontaminate equipment soiled by war gases or toxic products such as DES'DEC® Solution R2D2 / R2D4 from Ouvry or Easydecon DF 200®.
- DES'DEC® Solution R2D2 / R2D4 from Ouvry or Easydecon DF 200®.
- decontaminants are only marketed in the military environment and are not effective for decontaminating corrosive products which are very present in industry, such as acids or bases.
- fluoride-based compounds such as hydrofluoric acid
- a person skilled in the art must face an even more important problem. Indeed, in addition to eliminating the dangerousness linked to the corrosiveness of the chemical, it must also guard against its toxicity. Fluoride poisoning can occur following skin, digestive and / or inhalation exposure. It results in bone, respiratory and heart disorders that can lead to death. The potentially lethal dose is 5 mg / kg body weight.
- a chemical decontaminant for special material hydrofluoric acid and derivatives is LeVert HF.
- the latter decontaminates the surface of soiled equipment by reducing the pH of the contaminating chemical to between 5.5 and 9 and by fixing the fluoride ions. It is considered that the decontamination is effective when the threshold of non-dangerous concentration of fluoride ions of 1.5 mg / L is reached in the decontaminant-fluorinated chemical mixture.
- Those skilled in the art must use an external means (fluoride ion measuring strips, ionometer) to verify that this limit of 1.5 mg of fluoride ions per liter of waste is indeed reached.
- Le Vert HF chemical decontaminant is limited to hydrofluoric acid and other chemical compounds containing fluoride ions and therefore does not allow effective neutralization of basic chemicals. Such compositions are therefore not versatile and do not indicate the end of the decontamination operation. In addition, such compositions have a high concentration of NaCl salt, which corrodes metals.
