Lab Inspections

Lab Safety General Lab Safety Inspection Program

EH&S safety professionals inspect research labs with hazardous materials, hazardous operations, or biological materials. During inspections, EH&S safety professionals help researchers stay up to date on current safety requirements by providing consultations, support, and resources. Example inspection topics include, but are not limited to: training, chemical...

Laboratory Safety Self-inspections

Each year, EH&S initiates and tracks the completion of lab safety self-inspections, which are conducted by principal investigators or their delegates. The topics covered are designed to supplement inspections conducted by EH&S in order to facilitate safety awareness and ownership within the lab.To promote this effort, please complete your self-inspection in advance of your General Lab Safety inspection. EH&S recommends you complete your self-inspection 3 to 6 months relative to the General Lab Safety inspection.

The self-inspection questionnaire can be...

What happened?

A researcher was diagnosing a power loss from a Spectra Physics 3900 Ti-Sapphire (oscillator) that is pumped by a Spectra Physics Millennia eV DPSS laser. During this procedure, they noticed some leakage in the form of a slight green diffuse light being emitted from the end of the metal tube connecting the DPSS pump laser to the Ti-Sapphire laser. The researcher attempted to re-adjust the beam tube to eliminate the leakage to improve the beam tube alignment. As he touched the beam tube, it became dislodged from its mounting, striking the 532 nm laser beam as it fell, causing...

What happened?

A researcher walking towards an optical table was exposed to a laser beam that reflected off a hex ball driver tool. Another researcher at a nearby bench was installing an optical component on a breadboard when the hex ball driver he was using inadvertently moved into an active beam path. The hex ball tool had a reflective surface.

Office of Environment, Health, and Safety
Previously, updates to personnel approved to conduct research on a BUA were made on Labs At Berkeley (L@B), the web application used to manage lab roster and training information. There is no longer a need to make BUA personnel changes in L@B. BUA personnel changes can now only be made in RSS BUA.
