Last November, a researcher in a BSL2 lab was centrifuging stocks of a Risk Group 2 biological agent when the centrifuge experienced a catastrophic failure. The researcher heard a loud pop in the middle of the cycle and went to open the lid. The researcher determined the aerosol tight rotor bucket had cracked and carried it to the tissue culture room across the lab, not realizing the conical tubes inside were also broken. Since the biological agent spilled has an aerosol transmissible route of exposure, personnel present in the lab during the incident were advised to seek assistance from Occupational Health.

After nearly two years of effort, the campus-wide chemical inventory tagging project is wrapping up—and the results are remarkable. Since February 2024, our partners at Triumvirate Environmental have visited almost every lab and hazardous materials area on campus, placing barcode tags on chemical containers and logging them into the RSS Chemicals database. In total, the team has tagged more than 200,000 containers, creating one of the most comprehensive chemical inventories UC Berkeley has ever had.

A researcher was soldering on an open bench for extended periods of time over two days. The work was quite small and included soldering many wires to connectors. The researcher was exposed to soldering fumes resulting in irritation to the respiratory system. Symptoms experienced included watery eyes, coughing, chest tightness and dry nose & throat.
