2.2.1.1 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 sec) 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 beam for

a time long enough for the eyes to get injured.

2.2.1.2 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.

2.2.1.3 Precautions when dealing with a class 4 (US: class IV) laser machine

When dealing with class 4 (US: class IV) laser machine follow the following precautions:

- According to BGV B2 „Laser Emission“, a competent laser safety officer has to be appointed

in writing to evaluate potential hazards and to ensure that appropriate control measures are

implemented.

- The laser controlled area shall be posted with appropriate warning signs or warning lamps and

the area shall be defined to contain the laser radiation.

- The laser controlled area must be protected against unauthorized access.

- The operator of class 4 (US: class IV) laser systems always has to wear appropriate safety

glasses.

- An indicator (typically a light) to provide a warning of laser emission in advance of and during

the emission time.

Compliance with the points above does not absolve the operator from meeting the relevant standards

and guidelines for the operation of a class 4 (US: class IV) laser system.
