DEFINITION

Classification: 588/205

ORGANIC SUBSTANCE DESTROYED:

(under the class definition) Process for destroying or converting hazardous or toxic waste which contains either two atoms of carbon bonded to each other, one atom of carbon bonded to an atom of hydrogen or halogen, or one atom of carbon bonded to at least one atom of nitrogen by a single or double bond into a substance or substances which is environmentally safe.

(1) Note. Certain substances falling under the above definition are excluded from this and indented subclasses. Their destruction and conversion are classified in the subclasses below, to wit; hydrocyanic acid, cyanogen, isocyanic acid, cyanamide, cyanogen halides, isothiocyanic acid, fulmenic acid, and metal carbides.

(2) Note. The substance(s) that is destroyed maybe a mixture of hazardous or toxic waste with nonhazardous or nontoxic waste. Either component of the mixture being destroyed is sufficient for classification in subclass 205. Mandatory XR (cross-reference) into subclass(es) for the actual hazardous or toxic substance (component) destroyed in noted.

(3) Note. If the hazardous or toxic material is destroyed and a purified compound or composition is recovered search the appropriate compound or composition class.
