  1. DANGER ! Laser Safety Officer Workshop August 3-5, 2005 LLNL National Ignition Facility Host: Ken Barat

  2. LLNL Laser Safety Officer Workshop • Laser audits • DOE laser accidents • Implications for FEL

  3. Laser Audits LEADING INDICATOR IS : HOUSEKEEPING

  4. LAB AUDITS: 6 major criteria • Work control documents in place • Complete Hazard analysis • Adequate Hazard controls • Is training tailored • Is there adequate oversight:management and LSO • Medical

  5. Training Issues • Universal training • Refresher training • Alignment training • Student mentoring

  6. Medical • Victims must be transported “sitting up” in order to minimize further injury to the eye.

  7. Laser Accidents • 6 eye injuries since 2001 • Of note: • No eyewear worn during injury • 4 of the 6 injured were STUDENTS

  8. Root Causes • Inadequate Training: lack of understanding of the hazards • Inadequate LSO prescense : inadequate authority and training • Inadequate internal oversight by line management • Failure to wear eyewear

  9. Los Alamos Laser Accident: Scene • 20 year old student on the job less than 2 weeks, No experience with lasers, not an authorized laser user • PI was 5 time R&D 100 award winner, mentored over 30 students • non-nuclear, low hazard facility • Laser lab not inspected by LSO • PI’s at risk behavior raised by co-workers, but ignored

  10. Events leading up to incident • Experienced laser technician normally conducted alignment but was not on site • Work to be done was not covered by existing LSOP • PI and student not wearing eyewear

  11. Aftermath • Student suffered permanent loss of central vision in one eye • PI instructed student to sign off on LSOP after the accident

  12. Consequences • PI terminated • Student has permanent vision loss • Extended Shutdown of operations at Los Alamos • Recognition that a formal mentorship program is needed

  13. Issues for Jlab • Alignment training • Formal mentorship of students • Eye injuries: victim should be transported “sitting up” to minimize further damage to the eye. • Housekeeping

  14. FEL UV Lab

  15. FEL LAB 1

  16. Take Home Message • A complete hazard analysis of the laser system is necessary • Line management involvement and LSO oversight must happen and should be documented. • Personal responsibility for working safe: be aware of procedure details and wear eyewear. Report those who do not. • Good housekeeping is a leading indicator of how safe your lab is perceived to be.

  17. Upcoming Laser Audit Goals • Review DOE lessons learned • Be able to prove that safe work is happening: • Know procedures • CLEAN UP!!!!
