Laser Safety

Ensuring the safe use of lasers, laser systems, and non-ionizing radiation sources.

Workplace Safety

California state regulations require every employer to establish, implement and maintain an effective Injury & Illness Prevention Program (IIPP). In August 2017, the University adopted a campuswide Workplace Safety Program that serves as the University’s central IIPP for creating a safe and healthful work environment. Having one program for the whole University helps to improve access, consistency, and usability across all departments. EH&S is the responsible department for overseeing the campuswide Workplace Safety Program. The campus Workplace Safety Program is based on the Injury...

Laser Free Day - November 9, 2022

December 7, 2022
Laser Free Day Information Two laser safety presentations were held on Wednesday, November 9; 10:00am - 12:00pm and 2:00pm - 4:00pm. Both presentations were identical and were held in-person at 290 Hearst Memorial Mining Building and virtually via Zoom. Laser Use Principal Investigators (PIs) were encouraged to attend the session that worked best with their schedules. Online option

Those unable to attend in-person were encouraged to attend the virtual Zoom session. Those who were unable to attend in-person or virtually are encouraged to watch the following...

Laser Shutdown & Safety Day - November 9, 2022

October 28, 2022
The following message was sent to Laser Use Principal Investigators (PIs) on October 28, 2022. Laser Free Day - November 9, 2022 After nearly 20 years without any reported laser injuries and only a few laser incidents on the Berkeley campus, there have been 5 laser exposure incidents within the past 15 months. One incident led to minor, but permanent, retinal damage in a student. For each incident, there were violations of Standard Operating Procedures (SOPs) and/or failure to adhere to campus regulations on laser use.

In response to this uptick, I am...

Job Safety Analysis

Job Safety Analysis or JSAs 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.

Getting Started with Job Safety Analysis (JSA)

How do I write or find a JSA? The objective of providing this library is to:

Improve safety awareness among staff Decrease injury rates Make effective JSA resources available to the entire UC Berkeley campus

Labs At Berkeley (L@B)

Labs At Berkeley (L@B) is a web application, created by Berkeley EH&S, that allows any campus laboratory member to view and edit information about researchers in their lab.

Getting started with L@B

Log into L@B using your CalNet ID and you will see your lab’s roster. If you belong to more than one lab, select the name of the lab you wish to view or update from the pull-down list in the upper left corner of the page. To add or remove members,...

Laser Eye Exposure from a 1 Watt Class 4 Laser Beam

January 5, 2022
What happened?

A researcher was exposed to a 1 watt continuous wave beam from a Ti-Sapphire (852 nm) laser while visually inspecting a non-linear crystal on the optical table with a dielectric mirror. The researcher was unaware that the beam was present and it was directed into their right eye. The researcher was not wearing laser eye protection because they thought the laser was off.

Shortly after finishing the visual inspection, the researcher noticed a spot in their field of vision and realized that they had been exposed to the 852 nm laser beam. The researcher was seen at the...

Standard Operating Procedures (SOPs) Laser Template

Lasers-Class 3B or 4
Standard Operating Procedure

This Standard Operating Procedure (SOP) outlines requirements to be considered by an authorized user of the Type of Laser(s) or experiment as well as describes the normal operation of the laser and any hazards that may be encountered during normal operation. Finally, the SOP explains how to minimize any hazards and how to respond in an emergency situation. This document is to be reviewed one year from the date of approval or as conditions warrant, whichever is the shorter time period.
