General
Where do I find general information on hazardous waste?
EH&S HazMat has a dedicated portal that outlines: (a) the main waste streams generated at USC, (b) proper waste management and disposal, and (c) environmental compliance.
Find more information at https://ehs.usc.edu/hazmat-mgmt/ and the Hazardous Waste Management Manual.
How do I request a hazardous waste pick-up?
Visit the Request a Hazardous Waste Pickup website for details. Research and non-research areas can submit requests via online forms.
Once a pickup request is submitted, when will EH&S remove the waste items? Do I need to be present when the pickup occurs?
Allow 3 to 5 business days for processing the request and removal of the waste.
If the waste is in an established waste accumulation area (WAA), then it is not required for someone to be present.
Waste storage locations other than WAA that are locked during normal business hours need to have representatives present when EH&S HazMat arrives. Contact hazmat@usc.edu or (323) 442-2200 to re-schedule a pickup if personnel will not be available.
What waste containers does EH&S provide?
EH&S provides the following containers:
- Poly safety cans for flammable/combustible and halogenated solvent recycling
- Bio red bags and poly containers
- Red sharps containers
- Green sharps containers (for chemically-contaminated sharps)
- Pharmaceutical and Chemotherapy containers
- Pathological waste containers
- Fiber drums
- Poly bags
- Used battery containers
To request supplies, follow instructions in the EHSA SOP Waste Pickup + Supplies document (only for EHSA users) or by completing the Waste Supply Request Form on the EH&S Hazmat Website.
EH&S DOES NOT provide the following:
- Clean broken glass boxes or sturdy cardboard boxes
- Secondary containers/containment for stock chemicals, reagents, or waste storage (see Hazardous Waste Prep and Staging Guide Sheet)
- All other containers not supplied by EH&S.
Refer to the Hazardous Waste Guide Sheet for additional information on proper disposal.
Does USC have a recycling program for labs?
Recycling programs for labs at USC are in development. However, below are a few viable options for labs.
Pipet Boxes
- Ensure that pipet boxes are autoclavable and decontaminate for reuse/redistribution.
- Store small tools/items.
- Offer the decontaminated boxes to:
- Department of Animal Resources (DAR) to house lab mice
- Other groups/departments
- Schools in the area through USC’s community partners
- Recycle the boxes through the original manufacturer(s). (cost associated)
- Polycarbin – accepts any brand
Chemicals Exchange
- Share chemicals that are no longer needed with peer researchers.
- Donate chemicals to area schools.
What do I do in case of a hazardous spill? Who do I notify?
Follow instructions at the Spill Response and Clean-Up web page. For notifications, follow steps here: Spill Notification Procedure.
Does EH&S assist with relocating chemicals to a new lab space?
EH&S does not relocate chemicals if labs are moving to a new building on campus. Labs should contact their schools and/or contract with external vendors to assist with the move. However, Hazmat can assist with any hazardous waste that needs to be discarded prior to or after the move. In some instances, if your lab is moving to a new space within the same building, Hazmat may be able to assist. In all cases, please fill out the Lab Closeout Request Form to initiate the dialogue with Hazmat and Research Safety teams.
Hazardous Waste
How do I dispose of tissue samples stored in liquid PFA?
Option 1: Decant PFA into a separate labeled hazardous waste container. Discard the tissue in an approved bio container – see Hazardous Waste Disposal Guide Sheet.
Option 2: Treat the samples as chemical waste – see Waste Hierarchy. Note on the hazardous waste label that the container has bio tissue.
How do I dispose of paints and art supplies if I’m not affiliated with a research lab?
Non-research facilities/labs can request a pick-up of certain hazardous materials (visit the Universal Waste web site for the list) by completing and submitting the Universal Waste Supply Request Form.
How do I dispose of silica gel?
Labs that generate substantial quantities of silica gel waste can use fiber drums with poly bag liners supplied by EH&S HazMat.
What is the proper way to dispose of mixed glass with free flow liquid (i.e., tubes, ampules)?
Sealed tubes and ampules that contain liquids are placed in Ziploc/sealed bags (double bag if heavy) with a proper chemical waste label. DO NOT place these tubes/ampules with liquid in the sharps container.
Do I need to have lab waste removed prior to an EH&S Safety Inspection?
It is NOT urgent to remove waste containers from your lab prior to the inspection. Ensure that expired/unwanted waste is properly labeled and submitted for disposal before the inspection. Consult the Hazardous Waste Prep and Staging Guide Sheet for more information.
EH&S safety inspectors will request proof of submission during the inspection.
How do I dispose of old lab coats?
- If the lab coats are soiled with biohazards:
- Option A: Discard them directly into the solid biohazards bin with red bag.
- Option B: Launder them through USC’s vendor-provided laundering services and then discard in regular trash.
- If the lab coats are contaminated with chemicals:
- Option A: Discard them as hazardous waste directly into a labeled poly bag. Request a hazardous waste pickup.
- Option B: Launder them through USC’s vendor-provided laundering services and then discard in regular trash.
Waste Containers
What waste containers do I use for long stem pipets?
- Bio-contaminated glass pipets – red bio sharps container
- Bio-contaminated plastic pipets – bio red bag/polycontainer
- Chemical-contaminated glass pipets – non-infectious green sharps container
- Non-contaminated glass pipets – clean broken glass box
- Non-contaminated plastic pipets – poly bag for solid waste
Can disposable gloves go into regular trash?
- Uncontaminated disposable gloves may be placed in regular trash.
- Bio-contaminated gloves are placed in bio red bag/polycontainer.
