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 Hazardous 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.

Staff are trained on proper identification, management, handling, transport, and disposal of all hazardous materials and wastes.



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 Sysmex XN-430 analyzer are not considered hazardous and may be diluted with water and disposed of down the drain.

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 on the outside wall of the laboratory. 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.
