LASER SAFETY

  

The 

GA70

 utilises a Class II laser that emits low levels of visible radiation (i.e.  

  

wavelengths between 400 and 700 nanometres) which are safe for the skin but  

  

not inherently safe for the eyes. The Class II emission limit is set at the    

  

maximum level for which eye protection is normally afforded by natural aversion  

  

responses to bright light. Accidental eye exposure is therefore normally safe,  

  

although the natural aversion response can be overridden by deliberately staring  

  

into the beam, and can also be influenced by the use of alcohol or drugs.

‰

‰

‰

WARNING!

‰

DO NOT

 look or stare into the laser beam as permanent eye 

damage could result. 

‰

8

‰

DO NOT

 direct the laser beam at any person’s (or animal’s) eyes as eye damage 

could result. If the beam is obstructed by a person during use, release the 

contact switch immediately.

‰

8

‰

DO NOT

 use the equipment while under the influence of alcohol, drugs or whilst 

on medication.

‰

9

‰

Be aware that reflections of the laser beam from mirrors or other shiny surfaces 

can be as hazardous as direct eye exposure.
