Your scenarios are paraphrased and answered as I apologize for the delay in 01. A mixture or solution is neither significantly acidic or basic (pH 7).

We and 3267, versus UN1760. These issues do not seem to be specifically defined in the D.O.T., cannot find any definitive explanation for use of the newer, more specific UN3264, 3265, 3266, significantly acidic or basic, regardless of whether the technical component is an acid or base. For First, we would like an opinion about using UN1760 specifically when pH is not either nother example to consider: If the corrosive components are amines, is the more specific prop lipping name for UN2735 preferred, or if non-hazardous inorganic components are preser swea <<>> 08/01/03 FRI 10:14 FAX 630 305 2986 ENVIRN HITH SFTY 7003 ONDEO Nalco July 31, 2003 Thank you for your prompt response.
