Precautions for the laser
This function performs processing mainly with infrared light lasers.
These infrared lights are invisible laser light sources and are classified as Class 4
according to International Electrotechnical Commission (IEC) 60825-1:2014 ' Safety of
laser products - Part 1: Equipment classification and requirements.'
Class 4 lasers are considered dangerous if the skin or eyes are directly exposed to a
laser beam even momentarily, and even diffuse reflected light can harm the skin or
eyes. There is also a risk of fire. Always keep out of the processing room during
processing.
This function also uses Class 2 red laser pointer light to indicate the processing
position.
Class 2 lasers are considered safe lasers because danger can be avoided by an
aversion reaction of the eyes (blinking). However, there is deemed to be a potential
risk when observing a direct laser beam with optical instruments.
Use facilities that comply with the Safety Standards for Laser Beams (IEC 60825-1).
Note that Yaskawa does not guarantee the safety of facilities that comply with the
Safety Standards for Laser Beams (IEC 60825-1). Make the final decision regarding
the safety of your facilities after considering them carefully.
Description of laser classes
Class Description of the degree of risk
Class 1 Safe under any reasonably foreseeable operating conditions.
Class 1M Same as Class 1, except for an increased risk when using
optical instruments.
Class 2 Low power. Normally safe due to the protection afforded to the
eyes by aversion reactions (e.g., blinking).
Class 2M Same as Class 2, except for an increased risk when using
optical instruments.
Class 3R Increased risk with direct intrabeam exposure.
Class 3B Always dangerous with direct intrabeam exposure.
Class 4 High power. Even diffuse reflection is dangerous.
