<h3>Statement of Lessons Learned</h3>
<pre>On Monday, May 15, 2024, an employee and two post-doctorates initiated the procedure to energize lasers to perform helium polarization. Following the procedure, the laser keys were locked in the lock-box and the interlock system was placed in a "safe-state." In this state, no laser light was supposed to be able to enter the enclosure. However, while the laser enclosure was being monitoring for illuminated discharge plasma, a small background current was identified. This meant that some light was still present even though the enclosure was opened. (Opening the enclosure would normally trip the interlock and prevent the laser from operating.) While running tests to determine the source of the background current, the employee looked into the enclosure exposing the back of their head to 1mW of 1083 nm laser light. 

The employee went to the on-site Occupational Medicine clinic for an eye exam where it was determined they had possibly been exposed to reflection (there was no direct staring at the beam or optics). The employee felt no ill effects, and there was no change from the initial baseline eye exam.</pre>
<h3>Discussion of Activities</h3>
<pre><img src="https://misportal.jlab.org/ll/lessons/1201/show_attachment_content?attachment_id=7248
" width="500px">

In the system, three laser modules are powered by two similar power supplies. The two power supplies have identical cables (see photo above), but serving different purposes, (The modules were a low-power 1083 nm seed laser; a broadener, that expands a laser-line wavelength to cover the pumping line; and an amplifier, that increases the power of the broadener's laser-light between 0.1 to 10 W in the pumping laser system.)</pre>
<h3>Analysis</h3>
<pre>It was found that during a recent equipment reconfiguration the power supply cables had been switched, causing the low-power seed laser to disregard interlock or key status safety protocols resulting in a fail-unsafe condition. 

The employee contacted the manufacturer to discuss any possible administrative remedies, such as better labeling of the power supply cables or physically altering the connectors to make it impossible to plug them in incorrectly. The power supplies were manufactured in France, and it was acknowledged that the cords could easily be switched, but there was no acknowledgement that it was a flaw in the design as it met French regulations.</pre>
<h3>Recommended Actions</h3>
<pre>The employee labeled the cables and altered the pins to prevent future occurrence.

Engineer a control on the seed laser power connector and the broadener power supply cable to only allow the corresponding lead to connect to the item it belongs to.

Engineer a control to the interlock system to control instances when the interlock is broken/tripped to inhibit the laser system from working.

Review all seed laser systems to determine whether they fall prey to the same issue with mixing up the power leads.</pre>
