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.
Highly toxic waste, as defined in section III.F.2 of this manual, is very seldom if ever generated in
undergraduate teaching laboratories. When it is, specific procedures for removing it will be elaborated by
the lab manager and instructors for the particular teaching lab in question. When working with highly
toxic waste, one must work with it under a hood, pack it separately from other waste material, label it with
specific names, collect it in a container (all as a last step in the student’s reaction or experimental
procedure), and take it downstairs to the waste holding area in room #21.
All other waste materials are covered under procedures listed elsewhere in this manual. (consult
subchapter # 5, entitled "Waste from Undergraduate Labs", in section III.C). General Chemistry
procedures for relatively benign waste handling and removal are listed in the training section of this
manual.
Additional standard operating procedures for handling general chemistry lab waste are contained
in the instructor’s information sections for each "Modular Laboratory Program in Chemistry" series for
experiments assigned by the instructor.
The organic solvent waste procedures are likewise listed in the training section of this manual
with specific instructions listed in the aforementioned subchapter. Additional instructions are contained in
the present undergraduate Organic Lab textbook at the end of all experimental procedures.
