(b) Definitions.
(1) Absolute Filter. A filter capable of
						retaining 99.97 percent of a mono disperse aerosol of 0.3 micrometer
						particles.
(2) Authorized Employee.
						An employee whose duties require him to be in the regulated area and who has
						been specifically assigned by the employer.
(3) Chief. The Chief of the Division of
						Occupational Safety and Health, P.O. Box 420603, San Francisco, California

						entry from, a shower room when shower facilities are otherwise required by this
						section.
(5) Closed System. Any
						operation involving a carcinogen where containment prevents release into
						regulated areas, nonregulated areas or the external environment.
(6) Decontamination. The inactivation of a
						carcinogen or its safe disposal.
(7) Disposal. The safe removal of a
						carcinogen from the work environment.
(8) Emergency. An unforeseen circumstance or
						set of circumstances resulting in the release of a carcinogen which may result
						in exposure to, or contact with, the carcinogen.
(9) External Environment. Any environment
						external to regulated and nonregulated areas.
(10) Isolated System. A fully enclosed
						structure, other than the vessel of containment of a carcinogen, which is
						impervious to the passage of the carcinogen and which would prevent the entry
						of the carcinogen into regulated areas, nonregulated areas or the external
						environment should leakage or spillage from the vessel of containment
						occur.
(11) Laboratory Type Hood. A
						device enclosed on three sides and the top and bottom, designed and maintained
						so as to draw air inward at an average linear face velocity of 150 feet per
						minute with a minimum of 125 feet per minute; designed, constructed and
						maintained in such a way that an operation involving a carcinogen within the
						enclosure does not require the insertion of any portion of any employee's body
						other than hands and arms.
(12)
						Nonregulated Area. Any area under the control of the employer where entry and
						exit is neither restricted nor controlled.
(13) Open Vessel System. An operation
						involving a carcinogen in an open vessel which is not in an isolated system, in
						a laboratory type hood or in any other system affording equivalent protection
						against the entry of a carcinogen into regulated areas, nonregulated areas or
						the external environment.
(14)
						Protective Clothing. Clothing designed to protect an employee against contact
						with, or exposure to, a carcinogen.
(15) Regulated Area. An area where entry and
						exit is restricted and controlled.
