I have been getting ready for the annual safety inspection in the past 2-3 days.
Meaning cleaning up and disturbing the status quo on the floor mostly under the optical tables and their surroundings.
For example: pd power supplies, He/Ne laser ps. and their positions.
BNC cables and ac power line positions can be different.
The new rule: no electronic equipment on the floor.
All electronic equipment were moved-placed into a plastic dish or tray.
