Laser Safety TrainingCalifornia Campus Radiation Safety Officers Conference
October 2007
Researcher
Laser Safety Officer
Class 1 Incapable of causing injury during normal operation (Almost the same as ANSI class 1)
Class 1M Incapable of injury unless collecting optics are used (Currently included in class 1 under ANSI)
Class 2 Visible lasers incapable of causing injury in 0.25 s. (Same as ANSI class 2)
Class 2M Visible lasers incapable of causing injury in 0.25 s unless collecting optics are used (ANSI visible 3a with expanded or diverging
beam)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
(ANSI visible 3a with small beam & ANSI invisible 3a)
Class 3B Eye hazard for intrabeam viewing (Same as ANSI class 3b)
Class 4 Eye and skin hazard for both direct and scattered exposure (Same as ANSI class 4)
IEC 60825 Laser Classification

Concepts to Work By!
• Researchers do interesting things!
• What is our role in safety?
Training Materials Available• Video
– Laser Safety Primer by LPI (~$350)– Covers the basics– Nicely done
• Power Point– Laser Institute of America– Laser Safety for Student (LPI) – Free– Laser Safety Microcourse (LPI) – Free– Other Institutions – Probably Free– Other Laser Safety Officers – Free
• Computer Based Training– Developed by LLNL and UC
• Used by DOE• Available to the UC campuses• Now available to the CSU campuses through SJSU & CSU East Bay• What about other campuses?
Computer Based Training
• LLNL (Hazards Control Dept) & UC system developed a computer based training for laser safety.
• Available to the UC system with permission from LLNL.
• NOW available to the CSU system on a SJSU server.
• Cost to the UC & CSU campuses – ZERO• Do other campuses need this level of training?
Training Process
• Learner logs onto the sever.• Enter a six digit (control) number to identify
themselves.• Complete the modules.• Take a final examination.• Receive a computerized form stating they have
completed the course and exam.• Submit the form to the LSO.• Training is now completed.
