titleLaser Safety Meeting 7 December 2023

Meeting Minutes: 

 We had our first laser safety meeting with Mike Woods and these slides were presented: 231130 first laser safety meeting.pptx

    • We should look at commercial products to see how they are doing interlocks
    • Important things that our system should have:
      • Key
      • Emission Indicator (red/green)
      • interlocking
      • (optional) Emergency OFF button
    • The box should have 2 redundant interlocks in series
    • If the box is made up to specs we will not need a separate laser area and will not need eye protection to operate
    • Box material can be 80/20 Aluminum
    • For the feedthrough we should think of having an elbow to avoid direct line of sight
    • We have to take into account the fiber bend radius
    • SOP is not enough, we will need a separate approval to operate
    • People working on the assembly of this will need:
      • 253
      • 131
      • T53
    • People only operating will need only a simpler laser safety basic course
      • ???
    • Mike gave us permission to buy the laser

Next Steps: 

    • Mike Woods asked for a component list
    • Norman Picker asked us to start a Hazard list with Mitigation (All the risks will be Extremely low)
