"Embedded laser" means an enclosed laser with an assigned class
				number higher than the inherent capability of the laser system in which it is
				incorporated, where the system's lower classification (Class 1, 2, 3a or 3b) is
				appropriate due to the engineering features limiting accessible
				emission.
"Enclosed laser" means a laser that is contained within a
				protective housing of itself or of the laser or laser system in which it is
				incorporated.

"FDA" means the Food and Drug Administration of the United
				States Department of Health and Human Services.
"Fire-resistant material" means a material that is not
				combustible when used for its intended purpose in conjunction with a laser
				system.
"Incident" means an event or occurrence that results in a real
				or suspected intentional or accidental exposure to laser radiation that caused
				or has the potential to cause biological damage.
"Irradiance" means the radiant power incident on an element of
				a surface divided by the area of that element, expressed in watts per square
				centimeter (W cm-2).
"Joule" or "J" means a unit of energy: 1 joule = 1 watt
				second.
"Laser" means any device that can produce or amplify
				electromagnetic radiation at wavelengths greater than 180 nanometers but less
				than 1 millimeter, primarily by the process of controlled stimulated
				emission.
"Laser installation" means a location or facility where laser
				systems are produced, stored, disposed of or used for any purpose
				[420 ILCS 56/15
				].
"Laser radiation" means an electromagnetic radiation emitted
				from a laser system and includes all reflected radiation, any secondary
				radiation or other forms of energy resulting from the primary laser beam
				[420 ILCS 56/15
				].
"Laser safety officer" means any individual, qualified by
				training and experience in the evaluation and control of laser hazards, who is
				designated by the registrant to have the authority and responsibility to
				establish and administer the laser radiation protection program for a
				particular laser installation.
"Laser system" means a device, machine, equipment or other
				apparatus that applies a source of energy to a gas, liquid, crystal, or other
				solid substances or combination thereof in a manner that electromagnetic
				radiations of a relatively uniform wave length are amplified and emitted in a
				cohesive beam capable of transmitting the energy developed in a manner that may
				be harmful to living tissues, including but not limited to electromagnetic
				waves in the range of visible, infrared or ultraviolet light. Such systems in
				schools, colleges, occupational schools, and State colleges and other State
				institutions are also included in the definition of "laser systems". [420 ILCS
				56/15]
"Maintenance" means the performance of those adjustments or
				procedures by the user to keep equipment in its intended operating condition.
				Maintenance does not include operation or service as defined in this
				Section.
"Maximum permissible exposure" or "MPE" means that level of
				laser radiation to which persons may be exposed without adverse biological
				change in the eye or skin.
"Medical laser" means a laser system that is a medical device,
				as defined in
				21 USC
				321(h), and is manufactured,
				designed or intended for laser irradiation of any part of the human body for
				the purpose of diagnosis, surgery or therapy (see
				21 CFR
				1040.10(b) ).
"Operation" means the performance of tasks required for the
				equipment to perform its intended functions. It does not include maintenance or
				service tasks as defined in this Section.
"Operator" is an individual, group of individuals, partnership,
				firm, corporation, or association conducting the business or activities carried
				on within a laser installation [420 ILCS
				56/15 ].
"Optical density" or "OD" means a logarithmic expression of the
				optical attenuation afforded by a material.
OD
=
log10
incident power
transmitted power
"Optical fiber communications system" or "OFCS" means a system
				consisting of one or more laser transmitters, each of which is coupled to an
				individual optical fiber and is used for the transmission of information, e.g.,
				voice or data.

				company, partnership, firm, association, trust, estate, public or private
				institution, group, agency, political subdivision of this State, any other
				state or political subdivision or agency thereof and any legal successor,

				that are designed to prevent human access to laser radiation above the
				applicable MPE level.
"Pulse duration" means the time increment measured between the
				half-peak power points at the leading and trailing edges of a pulse.
