LASERs

The term LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. Light can be produced by atomic processes which generate laser light.

Depending on the class and wavelength of the laser, the biological hazards can include: eye damage, thermal damage, and UV damage to the skin. Other hazards include: chemical hazards, explosive hazards, non-beam radiation hazards; collateral radiation electrical safety hazards and flammability of laser beam enclosures.

This subject area describes the procedures and guidelines for working with lasers at Brookhaven National Laboratory (BNL). The subject area describes typical hazards associated with using lasers, delineates responsibilities, and identifies control measures. The procedures primarily address lasers and laser systems rated as Class 3b and 4.

The Subject area describes the procedures and guidelines for working with lasers at Brookhaven National Laboratory (BNL), according to the requirements established in the American National Standards Institute (ANSI), American National Standard for the Safe Use of Lasers, ANSI document: Z136.1-2000. This document contains procedures for conducting the safety hazard analysis, developing documentation on laser controlled areas, using class 2 and 3a lasers, and installing laser equipment. This subject area replaces ES&H Standard 2.3.1, Lasers.
