Management of Waste Containers
The integrity of waste containers shall
be checked frequently. Containers that are not in good conditions
shall be transferred to stable containers. If the transfer of the
contents is not feasible, place the entire bottle and content in a
cleaning chemical residue from labware and reagent bottles, use the
appropriate solvent, and collect all rinsate for waste disposal.
The organic rinsate can be consolidate into 5-gallon containers with
other solvents. Make sure there is less than 15% by mass water in
the organic waste stream.
rinsate waste can be consolidated with the laboratory solvents if they
are compatible. Do not collect oxidizer rinsate with
- When triple
rinsing use as little solvent as necessary to minimize the amount of
waste being generated by this process. As a rule of thumb, 25 ml
should be sufficient. Allow container to dry then dispose
of them as ordinary refuse.
residues can be rinsed with water and poured through limestone before
discharging down the sanitary drain. Rinsate from chromic acid
should not be poured down the drain but collected in glass bottles and
disposed of as hazardous waste.
- N.B. These empty containers will be removed by custodial services.
New Waste containers
5-gallon waste containers are located in the closet
next to Room 151 in the Chandler Building. The closet is open during business
hours so that laboratory may retrieve waste containers. Chemical waste labels are also stored in the closet.
Laboratory clean out Procedures
termination of a research project or completion of a
thesis, or the vacating of a laboratory space, the Chemistry department
shall notify EH&S to arrange for the safe storage and disposal of
the chemicals. Once notification has been received, all chemicals
within the laboratory or work area shall be removed. Each
investigator shall identify any waste material before his or her
departure. Unidentified materials will be treated as extremely
hazardous. Unidentified materials cannot be removed for disposal
until it is properly classified.
- In an effort to minimize the quantity and cost of waste generated by the University,
other laboratories will be given an opportunity to procure much-needed
chemicals for their use. Chemicals left over will then be
processed for disposal.
surfaces shall be decontaminated. Once the space has been cleared
for occupancy, the Safety officer will notify the chemistry Department.
