Lasers are devices that optically amplify and emit coherent beams of electromagnetic radiation usually in the ultraviolet, visible, or infrared regions of the spectrum, it is a type of non-ionizing radiation. Even though radiation from them is non-ionizing, it can still be dangerous – severe eye damage, skin burns, or internal organ damage can occur as a result of overexposure to non-ionizing radiation.

All Class 3b and Class 4 lasers must be registered with EHS and must comply with safety guidelines of the American National Standard for Safe Use of Lasers in Research, Development, or Testing (ANSI Z136.8-2012). To register a Class 3b or Class 4 laser, please complete a Laser Equipment Registration Form and submit to EHS.

All users of Class 3b and 4 lasers must receive Laser Safety Training prior to working with these devices in the laboratory.

For additional information on ionizing or non-ionizing radiation safety programs, or to request training or assistance, please contact the Radiation Safety Officer.
