A. Safety Precautions
(1) The Nano engraves and cuts materials by the means of a
high-energy diode laser beam.
The hazards associated with a high-energy diode laser beam include
the possibility of fires, generation of hazardous and/or irritating
toxic fumes, but more importantly damage to eyes and skin.
(2) Laser engravers are divided into several internationally valid
classes based on their performance and the risk of injury. The Nano
falls into the Class IV (Class 4 IEC standard focus on the American
FDA classification).
Laser class
Class Definition
Class I
Class I laser radiation is not considered hazardous.
Class IIa
Class IIa laser radiation is not considered hazardous if viewed for any
period of time less than or equal to 1x10
3
seconds but is considered
a chronic viewing hazard for any period of time greater than 1x10
3
seconds.
Class II
Class II laser radiation is considered a chronic viewing hazard.
Class IIIa
Class IIIa laser radiation is, depending upon the irradiance, either an
acute intrabeam viewing hazard or chronic viewing hazard. If viewed
directly with optical instruments, Class IIIa laser radiation is classified
as an acute viewing hazard.
