Chapter 10: Laser Safety

The purpose of this program is to mitigate the hazards posed by optical lasers, which operate at wavelengths between 180 nanometer and 1 millimeter. High-power lasers (Class 3B and Class 4) are used at SLAC in research and accelerator operations. The primary hazard associated with their operation is potential eye damage; other potential hazards include skin burns, electrical currents, explosions, fires, toxic material, laser-generated air contaminants, collateral radiation, noise, and ultraviolet light. Low-power lasers (Class 2 and Class 3R) include laser pointers and alignment lasers; they are safe when used as intended, but require some controls.

This program covers the setup and operation of high-power lasers, including the approval of laser controlled areas (LCAs) and of qualified laser operators (QLOs) and system laser safety officers (SLSOs). It also covers the operation of low-power lasers. It applies to workers who use low-power lasers, operate high-power lasers, or may access labs where such lasers operate; their line management, supervisors, points of contact, and ESH coordinators; and laser lab program managers, SLSOs, the laser safety officer (LSO), associate laboratory directors (ALDs), and Occupational Health and Purchasing.
