Lasers are classified for safety purposes based on their potential for causing injury to humans' eyes and skin. For visible-beam consumer lasers, there are four main classes. Class I A Class I laser is safe under all conditions of normal use. This means the maximum permissible exposure (MPE...
Class 3R laser systems like laser pointers and laser scanners pose a higher safety risk than previous classes, but they’re still considered safe when handled carefully. Eye injuries may occur if you directly view the beam—especially when using optical instruments. But generally speaking, a brief...

SLAC National Accelerator Laboratory has developed a Laser Alignment Practical Training Course as one of its core laser safety classes. The course is taught to small groups of up to three students and takes 1-3 hours to complete. This practical course is not a substitute for site-specific On-...
There are four main classes for visible-beam lasers: Class 2, Class 3R, Class 3B and Class 4. The first two are relatively safe for eye exposure; the last two are hazardous. The chart below shows that the eye injury hazard increases as the laser’s power increases....
Laser Safety Regulations Laser Categories According to ANSI Z136.1 and EN 60825-1 Lasers are categorized into seven hazard classes based on accessible emission limits (AELs). These limits indicate the hazard class of the laser and are listed in the American National Standards ANSI Z136.1 for Safe...
