Laser Operator and SLSO Restart Requirements

On Thursday, September 24 there was a laser accident resulting in an injury to a laser operator. Following the accident, a stop work order was issued for all Class 3B and Class 4 lasers in SLAC research laboratories.  Information on the accident and restart criteria for Class 3B and Class 4 lasers at SLAC is provided at the internal Sharepoint site  https://slacspace.slac.stanford.edu/sites/esh/rp/laser/09restart.  The restart criteria require laser operators and System Laser Safety Officers (SLSOs) receive additional training and be re-approved.  Important training information for these personnel to restart work with 3B and 4 lasers follows.

QLO approval to restart laser work following the 9/24 laser injury accident requires:

1. Attendance at 9/25 Mandatory QLO meeting; or if the QLO missed this meeting, s/he must review the 2 files listed below and meet with LSO to discuss (suggest this be done after completion of the course in item 3).

   • 25sep09_AccidentSummary.pdf

   These are available at the Sharepoint site, https://slacspace.slac.stanford.edu/sites/esh/rp/laser/09restart

2. Complete new 253PRA course, which has 2 parts and is provided by the SLSO -- a common practical training which takes about 45 minutes and site-specific training.
3. Complete the new class “Laser Accident-Lessons Learned”.

SLSO approval requirements for laser facility restart:

1. ESH 130 Laser Supervisor Safety course.  This course is generally offered once per month, but a special course time will be held:
   • Friday 10/2  2:00-4:30 PM in the Kavli Auditorium

   Course catalog information for this course is at https://www-internal.slac.stanford.edu/esh-db/training/slaconly/bin/catalog_item.asp?course=130

   PowerPoint slides with course material is available at  https://slacspace.slac.stanford.edu/sites/esh/rp/laser/Training

2. The SLSO will meet individually with the LSO to review readiness to return to safe operations with adequate safety supervision for laser personnel.
3. SLSOs must get re-approval authorization from the LSO, program manager and ALD.

The ESH 130 course is required for SLSOs but is also recommended to people who have supervisory roles for laser personnel or facilities.
