METHOD OF SURFACE DECONTAMINATION AT NEGATIVE TEMPERATURE AND DETERMINATION OF DECONTAMINATION FULLNESS Russian patent published in 2002 - IPC

FIELD: medicine, microbiology, veterinary sanitation. SUBSTANCE: contaminated and cooled to formation of strength ice crust test-surfaces are decontaminated by low-freezing solutions of activated and nonactivated forms of potassium fluoride peroxohydrate as antifreeze where one of aliphatic alcohol is added. Consumption norm is 250-750 ml/m² for 15-45 min for spore form of microorganisms and 100-300 ml/m² in exposition for 1-5 min for vegetative form. Method ensures to use disinfecting agent at temperature below +10 C. Invention can be used for decontamination of surfaces of different objects of technological compartments, equipment, devices, tools, adaptors, surfaces, storage containers and for suspension treatment of nonconditioned productions and industrial flows. EFFECT: improved method of decontamination. 3 cl, 4 tbl, 8 ex
