<h2 style="white-space:nowrap">Statement of Lessons Learned</h2>
<pre>Maintained safety configurations when making system modifications. Consult with a Subject Matter Experts (SMEs) prior to making modifications and after, to determine if a safety systems inspection is required.</pre>
<h2 style="white-space:nowrap">Discussion of Activities</h2>
<pre>Modifications made to a laser enclosures resulted in less than adequate containment of hazardous laser emissions. </pre>
<h2 style="white-space:nowrap">Analysis</h2>
<pre>On July 15, 2019, a worker observed a green flash of light from an adjacent part of the building where a Class 4 laser was operating. Following the flash, the worker went to the Occupational Medicine facility for evaluation. No injuries were identified.
Following the incident a safety walk-down was performed. It was discovered that the enclosure around the laser work area, intended to keep the laser system in a Class 1 mode, had been modified without proper review or discussion with the Laser Safety Officer (LSO). New holes had been made in the enclosures and were sealed with panels that neither interlocked nor required a tool for access.
The result of these modifications was that the enclosure no longer contained all the hazardous laser emissions. During subsequent operations , one of the modified panels had dislodged allowing diffuse laser light to escape into adjacent work areas.</pre>
<h2 style="white-space:nowrap">Recommended Actions</h2>
<pre>The event emphasizes the need to continuously evaluate safety envelopes as work evolves. This especially applies to hazardous work when mitigated to a non-hazardous level.
1. Continually question changes outside the scope of the approved work plan. Encourage consultation with SMEs for guidance.
2. Request an SME evaluation when any modification is made to a device or equipment setup. Even if previously inspected and approved.
3. Consider disassemble and reassemble of a system to be a modifications. Ensure that the rebuilt system continues to meet the required safety guidelines. Request an SME evaluation prior to continuation of work. </pre>
<h2 style="white-space:nowrap">JLab Preventive Measures</h2>
<pre>Jefferson Lab has determined that working with Class 3B and Class 4 carries an unmitigated Risk Code > 2. At a minimum all tasks requiring these lasers are discussed with the supervisor prior to commencement of work. A Laser Operational Safety Procedure (LOSP) is written for work considered to be Risk Code >2 in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process. ES&H Manual Chapter 6410 Appendix T1 Laser Operational Safety Procedure (LOSP) has been developed to ensure hazard issues are identified through a Task Hazard Analysis, are adequately addressed, and appropriately mitigated before activities involving lasers are approved or commence.
Only Qualified Laser Workers are authorized to work with Class 3B and Class 4 Lasers. Training requirements include: "SAF114O Laser Orientation" and "MED02 Eye Exam for Laser Safety."
