FIELD: chemistry.
SUBSTANCE: to carry out complex deactivation, disinfection and detection of traces of tetranitrotoluene-based explosive substances aerosol spraying on the surface of combined indicator composition, which includes polyhexamethylenguanidine hydrochloride; catamine AB; alkylbenzolsulphonate; methyl alcohol; non-ionogenic surface-active substance (OP-10); citric acid; sodium hexamethaphosphate; dithizine; water, is performed. Polyfunctional composition is applied by irrigation of analysed surface by means of aerosol device from distance 0.1-0.2 m from it from leeward side with consumption 0.6-0.7 l/sq. m. Polyfunctional composition is applied by irrigation of analysing surface due to aerosol device from distance 0.1-0.15 m from it from leeward side with discharge 0.5-0.6 l/m2.
EFFECT: invention realisation makes it possible to carry out deactivation and disinfection after not less than 0,5 h after carrying out processing and realise detection of traces of dinitrotoluene-based explosive substances by appearance of characteristic indication effect - brown colouring on object surface, 4-5 minutes after application of polyfunctional composition, remaining for a long time.
