SPECIFIC PROCEDURES FOR SAFE REMOVAL OF HIGHLY TOXIC WASTE
Consult with your research advisor concerning proper methods for packaging and storing extremely
hazardous waste. Research usually involves working with selective types or classes of chemicals. Prepare
brief summaries in this section for handling spent chemicals peculiar to your lab.
The following common laboratory organic solvents can be collected in a waste container, labeled
NON- SULFUR, NON-HALOGENATED ORGANIC SOLVENTS and be poured into one of the two 55
gallon waste drums located in the solvent room, #20, assuming they are not overly contaminated with acids
or large amounts of toxic or odoriferous sulfur compounds. Each chemical should be recorded by name
and amount.
acetone methyl ethyl ketone pump oil
benzaldehyde mineral spirits tetrahydrofuran
benzene motor oil toluene
cyclohexane naphtha xylenes
ethyl ether paint thinner ethyl alcohol, (and,
ethyl acetate petroleum ether low-molecular weight alcohols,
The methylene chloride and chloroform must be collected in a well-labeled waste bottle and can be poured
into labeled 20 liter empty white polyethylene containers kept next to the large 55 gallon steel drum on the
floor in the wide yellow spill tray in the solvent room, #20. Sulfur containing compounds, complex
heterocyclics, corrosives, organic acids, lachrymators, etc. (i.e. thiophene, pyrrole, acetonitrile, etc.)
should be collected into well-labeled waste bottles and taken to the metal surface in the solvent room, #20.
Consolidate compatible inorganic solids in a well-labeled waste container, organic solids in another.
These can be placed on the metal surface table in the solvent room #20. Non-compatible solids should
naturally be packaged separately.
Typical waste streams originating from Dr. Noftle’s research lab are as follows:
Organic Solvents (Non-Halogenated)
Ethyl Acetate, Hexanes, Acetone
Diethyl Ether, Methanol, Ethanol
Tetrahydrofuran, Toluene, Pentane
Cyclohexane, Benzene, Acetonitrile, and occasionally Nitrobenzene
Halogenated Solvents
Methylene chloride, chloroform
Acetone, with:
tetrabutylammonium perchlorate tetrabutylammonium hexafluorophosphate
tetrabutylammonium trifluoromethanesulfonate
copper(II) perchlorate hexahydrate copper(II) trifluoromethanesulfonate
copper(II) acetate monohydrate copper(II) chloride
zinc(II) perchlorate hexahydrate zinc(II) trifluoromethanesulfonate
N2-(2-pyridylmethyl)-3-thienyl carboxamide
N2-(2-pyridylmethyl)-3-thenyl carboxamide
N2-(2-pyridylmethyl)-5-(3-thienyl)-butyl carboxamide
N2-(2-pyridylmethyl)-trans-3-(3-thienyl) acrylamide
