Areas Of Responsibility; Responsibilities Of The Operating Company - Trotec Speedy 400 Operating Manual

Class 2 (US: class II)
The accessible laser radiation of Class 2 (US: Class II) laser systems does not pose any hazard for the skin. Diffuse
reflections as well as any short-term irradiation of the eyes (exposure time max. 0.25 seconds) also pose no risk due to
the low output power.
However, it is possible to suppress the natural eyelid closure reflex and stare into the class-2 laser beam for a time long
enough for the eyes to get injured.
Class 4 (US: class IV)
Class 4 (US: class IV) high powered lasers (visible or invisible) considered to present potential acute hazard to the eye
and skin for both direct and scatter (diffused) conditions.
Also have potential hazard considerations for fire (ignition) and byproduct emissions from target or process materials. It
is the responsibility of the operator of the machine to take appropriate measurements to eliminate any dangers such as
fire or explosions through the laser beam.
