EXALGO. Flammable organic solvents that are safe in low exposures, such as ethanol, methanol, and acetone can often simply be burned outside for disposal, as most often their combustion products are simply carbon dioxide and water. To dispose of these chemicals, place the containers in a box lined with a plastic bag, tape the top of (USCG, 1999). Before neutralizing them, always dilute the acid first, to limit splashing or boiling the acid. Water soluble. WebHazardous decomposition products:Zinc or zinc oxides. Mineral acids and bases should be neutralized to pH5.5 to 9 range before disposal, following approved procedures. Many compounds of chromium, especially chromium(VI), are poisonous and carcinogenic.
