For the puZ~poses of the process according the invention,

preferably an aqueous solution is sprayed in the 'form of -a mist, in particular when sealed rooms have to be deconta- minated. Sut~befor this purpose ax6, ,for example, spray cans with or ~without propellent, hand spray equipment and, 'tquipment formning an intenziv;e smoke cloud, p.e. a club- shaped cloud after a short spray.' However, the solution ca.,n

also be applied as such to contaminated articles or-persons by means o~f brush cloths or o~ther equipment, and that 1.0 prevents further gasification of the irritants which are frequently.-in liqui4*fcrm and, gt the j~fpe time, the decon- Otamination is effected. 04 000
