LASER HAZARD CLASSES
Lasers are classified according to the level of HAZARD that is possible during normal operation.
اسلاید 10 :
LASER CLASSIFICATION SUMMARY
Class 1 Incapable of causing injury during normal operation
Class 1M Incapable of causing injury during normal operation
unless collecting optics are used
Class 2 Visible lasers incapable of causing injury in 0.25 s.
BAR CODE SCANNERS
Class 2M Visible lasers incapable of causing injury in 0.25 s
unless collecting optics are used
Class 3R Marginally unsafe for intrabeam viewing; up to 5 times the class 2 limit for visible lasers or 5 times the class 1 limit for invisible lasers (RED LASER POINTERS)
Class 3B Eye hazard for intrabeam viewing, usually not an eye
hazard for diffuse viewing (MEDICAL LASERS)
Class 4 Eye and skin hazard for both direct and scattered exposure
MOST MEDICAL LASERS
