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...

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.

Eye Exposure to Specular Reflection

July 31, 2015
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...

Laser Eye Exposure from a Specular Reflection

June 17, 2024
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.
