The clinical laboratory generates materials that are considered hazardous and/or biohazardous waste. The handling of and storage of hazardous materials and hazardous waste will be monitored regularly according to University requirements.

The clinical laboratory completes and maintains a "Storage Area Self-Inspection Form" for Hazarous Materials/Hazardous Waste. The form is completed weekly. The form includes: Inspection date, Area free of spills or leaks, Proper secondary containment, Contaminant clean, Containers labeled, Incompatibles segregated, Waste tagged and dated, Waste within storage time, Emergency procedure posting, and Inspectors initials and Comments/Corrective Actions.



Hazardous Waste

Wright stain and Gram Stain washings are considered hazardous waste. The washings are collected in e-tagged (UCSC online hazardous waste program WASTe) leakproof containers and stored until two thirds full or 90 days whichever comes first. They are subsequently picked up by UCSC EHS department.

Leftover reagents from the Beckman Coulter AcT analyzer are sprayed with Cavicide disinfectant to remove any possible biohazardous waste on the outside of the container, then e-tagged and subsequently picked up by UCSC EHS.


Biohazardous Waste

The biohazardous waste the lab generates consists of blood tubes and any visibly bloody tissues, papers or containers. Blood tubes are disposed of in sharps containers and then deposited in the biohazardous waste receptacle located in the lab storage closet. Bloody materials are put in the red bags lining the self closing waste cans under the counters in the lab. The red bags are then deposited in the biohazardous waste receptacle located in the closet.
