    Emergency means an unforeseen circumstance or set of circumstances 
resulting in the release of a carcinogen addressed by this section that 
may result in exposure to or contact with the material.
    External environment means any environment external to regulated and 
nonregulated areas.
    Isolated system means a fully enclosed structure other than the 
vessel of containment of a carcinogen addressed by this section that is 
impervious to the passage of the material and would prevent the entry of 
the carcinogen addressed by this section into regulated areas, 
nonregulated areas, or the external environment, should leakage or 
spillage from the vessel of containment occur.
    Laboratory-type hood is a device enclosed on the 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 addressed by this section 
within the hood does not require the insertion of any portion of any 
employee's body other than his hands and arms.
    Nonregulated area means any area under the control of the employer 
where entry and exit is neither restricted nor controlled.
    Open-vessel system means an operation involving a carcinogen 
addressed by this section in an open vessel that is not in an isolated 
system, a laboratory-type hood, nor in any other system affording 
equivalent protection against the entry of the material into regulated 
areas, non-regulated areas, or the external environment.
    Protective clothing means clothing designed to protect an employee 
against contact with or exposure to a carcinogen addressed by this 
section.
    Regulated area means an area where entry and exit is restricted and 
controlled.
