Clean up & Waste Disposal

Estimated Total Time: 10 minutes

Summary: Many people use the lab. Good lab hygiene is a must!


Electrical

Cleanup:

  • Resistors and capacitors can be thrown in the trash - they sell for less than a $0.01; It would be more problematic finding the wrong component in a drawer.

  • Return all semi-conductors: LEDs, diodes, and active components (op-amps, voltage regulators, etc), 

  • Wires can be thrown in the trash; however, if you have a locker in the lab, you may wish to save the wires for later use.

  • Return all equipment (eg. power supplies & soldering irons) and breadboards.


Chemical & Biological

SAFETY: Wear appropriate PPE at all times. You are handling waste.

 

Cleanup:

  • Put all equipment and extra supplies in their designated locations (Locations on General Inventory List).

  • Remove all labeling tape from glass/plasticware.

  • Wash all glassware and containers used, and hang them from the racks above the sinks.

  • Replace all reagents in their proper locations.

  • Wipe down all used surfaces with a 70% Isopropyl Alcohol Solution.

  • Dispose of waste, hazardous and non-hazardous.  

  • Consult Lab Staff if unsure about any of the above.

 

The Waste Pathway:

The laboratory disposes of waste in many separate ways. Each type of waste is classified by the risks it poses, and is disposed of in a manner commensurate with said risk. Therefore, this is what you do:

Waste Materials

Disposal Containers

Chemically or Biologically contaminated Glass or Plastic that can be perceived as Sharp. Non-Liquid, Non-sharps that are biologically contaminated – For instance, agar plates.

 

Paper wrappers, such as for pipettes, do NOT belong here.

Red Biohazard Containers

Broken glass

White Glass Disposal Boxes (please contact lab staff first)

Liquid Waste

Consult Lab Staff


  • GLOVES, PAPER TOWELS, KIMWIPES, PAPER WRAPPERS, MAY ALL GO INTO THE REGULAR TRASH.

  • GELS FROM ELECTROPHORESES MUST BE WRAPPED IN SARAN WRAP, WHEREUPON THEY CAN BE THROWN INTO THE TRASH.

  • IF IN DOUBT, ASK!
