Disposal of Unwanted Equipment through Surplus Sales

Equipment Requiring Special Decontamination Procedures

• If isotopes were used with your equipment, please request a radiation decontamination clearance from EH&S before decontaminating the unit. If your unit shows signs of radiation contamination, follow EH&S's instructions on how to decontaminate and safely prepare the unwanted unit for disposal.
• If ethidium bromide was used with your equipment:
  1. wash all surfaces with warm soapy water
  2. Wear appropriate PPE (lab coat, gloves, safety glasses) and collect all materials used in clean-up (all liquid, gloves, paper towels) as hazardous waste.
  3. Tag the clean-up material and have EH&S pick it up

Steps to Dispose of Unwanted Equipment

1. Request radiation decontamination clearance (if applicable)
2. Clean and decontaminate equipment. This means to scrub away visible, dried up spill/chemical residue with warm soapy water, and wipe all surfaces with freshly made 10% bleach.
3. Email greentag@biology.ucsd.edu for a ‘green tag’ to indicate that the equipment is free of contamination
4. To request a Surplus Sales pick-up and to make adjustments to the faculty’s equipment inventory, please see instructions on how to submit a Surplus Sales Transfer Request (STR).
