At Dow in the 70s, reactions running unattended (day or night) had to run failsafe. ... Jim

When I was a graduate student in Cambridge 1991-94 any apparatus left running overnight needed to be inspected by a technician and display a signed and dated placard during overnight operation. I believe the inspections focused on making sure there was adequate cooling, pressure relief, and secure clamping etc. Labs were closed to personnel after 12 midnight.

If you have developed a formal system that serves this purpose, I would appreciate it if you would share an URL to the form or a PDF copy of the form. I'll provide a list of what I receive to the list later this week.
