A JSA describes job tasks in step-by-step fashion, identifies associated hazards at each step, and outlines proper hazard controls that minimize the risk of injury or illness to the individual(s) performing that task.
The University of California, Berkeley is committed to providing a safe and healthy working environment for the campus community. Faculty, students, and other personnel in laboratories and other academic settings may work with hazardous materials, equipment, and processes. With regard to safety and environmental protection, this teaching, and research work is governed by state and federal regulations and University policies.
A standard operating procedure (SOP) is a set of instructions for performing experiments or processes that involve hazards (chemical, physical, biological, radiation). SOPs are lab-specific and include documentation of the people who have received training for that procedure.
New students and employees working in your lab should be provided with hands-on training for hazardous materials and operations that are covered by the SOPs for your lab.

In April 2003, the Non-Ionizing Radiation Safety Committee (NIRSC) informed the laser research community that a serious laser eye injury had occurred on the UC Berkeley campus. The campus Laboratory Safety Officer (LSO) performed an investigation of the incident. The following information and lessons learned are based on the LSO’s investigation of the incident.
The incident involved a short pulse, Class 4, invisible (1064 nm), Nd:YAG laser in a multi-user laser laboratory. During alignment of the laser's Nd:YAG beam, a graduate student was struck in the...
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...
