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.
