Laser Safety

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

Standard Operating Procedures (SOPs) for Labs

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.

Office of Environment, Health, and Safety

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.

What Happened?

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...

Eye Exposure to Specular Reflection

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...

Eyewear - Protecting Your Eyes Fact Sheet

Office of Environment, Health & Safety
2006

More than 90,000 eye injuries occur each year in the United States. Many of these could have been prevented with proper protective eyewear. The California Occupational Safety and Health Administration (Cal/OSHA) requires that protective eyewear be worn wherever there is the potential for injury from flying particles, hazardous substances, or dangerous light. The eyewear must meet the standards put forth by the American National Standards Institute (ANSI) in Standard Z87.1-1989. Safety eyewear that meets this standard has “Z87.1” imprinted on the frame or lens. Since eye hazards are common...
