Safety Precautions
1)The RAY5 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 RAY5
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 1x103
seconds, but is considered a chronic
viewing hazard for any period of time
greater than 1x103 seconds.
Class IIa Class II laser radiation is considered a
chronic viewing hazard.
Class II
Class IIIa laser radiation is,
depending upon the irradiance,
either an acute in- trabeam viewing
hazard or chronic viewing hazard. If
viewed directly with optical
instruments, Class IIIa laser
radiation is classified as an acute
viewing hazard.
Class IIIb
Direct Class IIIb laser radiation is
considered an acute hazard to the
