Unwanted, minor currents or voltages in an electrical system.

Nominal Hazard Zone

Abbreviated NHZ.  The space within which the level of the direct, reflected or scattered radiation may exceed the applicable MPE. Exposure levels beyond the boundary of the NHZ are below the appropriate MPE.

Non-beam Hazard

A class of hazards that result from factors other than direct human exposure to a laser beam.

[box]Examples: electrical, resistive heating, collateral and plasma radiation, fire, robotic mechanical hazards, etc.[/box]
