I hesitated to respond to this, Chuck, because I might be exaggerating a little,
but…
When I started in the Department of Chemistry's NMR Chemistry at Berkeley about
"100 years ago", the probe needed cleaning every week!! I immediately banned
touching the collar to avoid what we termed ‘Kentucky Fried Syndrome”.
The result was that we never needed to clean the probe again for a year. So,
you are right that spinning is not such a deal now, but I would heartily recommend
a ban on touching the collar!
Best!

Does anyone have a rule about spinner housing handling, like picked up only
with a Kimwipe? At U of Utah in the 80’s this was a strict requirement.
The idea was to keep the spinners clean so they would spin, maybe less important these days.

Hi Heike. Great topic!
Basic requirements:
* No eating or drinking in the lab. Water bottles brought in backpacks
can stay in there; others should be left by the door, preferably in the hall.
* No chemical mixing in the magnet rooms. All samples must be capped/sealed
when brough in, and must stay that way until they are taken from the lab.
* We do have an adjacent support lab w/ a hood, bench, eyewash station,
and sink, so people can start reacitons and do titrations there.
* Secondary containers are required for bringing samples in and out of
the lab. I found a resource to supply cheap white plastic flasks that people
can personalize<
https://chemnmrlab.uchicago.edu/community/*safetyflasks>
with craft supplies, and compliance has been high.
Our PPE requirements:
* Safety glasses not required, but OK to wear (safety is on the fence about
this; sometimes they say they’d like to reuire them)
* Lab coats prohibited (unless brought to the support lab and stay there).
This prevents contamination of the lab surfaces, including furniture. People
actually compain to me when they see someone where a lab coat in the NMR lab.
* Gloves worn in their labs are prohibited to stop contamination, but fresh
gloves provided hy the facility are permitted.
* After COVID lockdown’s glove requirement, we found some people
prefer wearing gloves, so we continue to supply them.
* To signal that the gloves are fresh, we only provide *pink* gloves on
our safety cart. As far as I know, none of the labs regularly uses pink
gloves, so if you see someone wearing them at a spectrometer, you can be
assured that they’re fresh from our cart.
* We occasionally have difficulty meshing our requirement with the
institutional “one glove” rule, which enables people carrying
samples between labs to carry samples with a gloved hand but use an ungloved
hand to open doors, push elevator buttons, etc. Sometimes people wear their one
glove into lab and start handling samples and typing without taking that glove
off. I need to remind them to take that glove off right away; I’m working
on signage to communicate that more consistently and visibly.
I have some additional thoughts on safety signage, especially magnet signage,
but maybe I’ll start a separate thread about that.
Thanks for bringing up the topic!
