The contributors propose a new technique of cleaning overalls in galvanic shops from crystalline natrium cyanide (NC) and alkaline solutions. The technique includes washing in hot 0.05% syntamide-5 solution for 4-5 min., double rinsing and centrifuging. The remaining quantity of NC on washed overalls does not exceed 0.02 mg/m2 (evaluated in hydrocyanic acid). Subsequent contaminations of the overalls with NC do not entail the accumulation of NC residual content. The physical and chemical characteristics of this type of overall washing are more preferable as compared to those attained through soaking in ferric sulfate solution.
