Hi Ken,
Been through some major renovations but none that were this messy. I would
consider moving the magnets for this. In particular, if there is another
large-enough room closeby that has a flat floor accessing it, and can be
separated by high quality air filtering, then roll the magnets live into
that room. Have the work done in the main lab, and roll magnets back in
after the work is done there. Moving the magnets live of course isn't
without risk, but if the floor is flat and door frame issues can be
removed/minimized then this may be better than having wrapped up magnets
living in a really dusty work zone.
I'd just consider this. Makes me queasy thinking about it. But I've moved
magnets live and those managed ok.
You might also consider carpeting the lab instead of redoing the old painted
surface. We did this in Madison using high quality carpet squares and that
worked (and looks) great.

> Subject: [AMMRL] AMMRL: Grinding up resin floor in NMR facility
As part of the restoration of the basement in our building post flooding, it
has been decided to redo the floors in all of the labs. The labs are painted
with a heavy-duty resin based paint. This floor pain was cracking and
chipping before the flood and its decay has been accelerated post flood.
Most labs are empty pending replacement equipment, but the magnets in our
facility survived the flood (the consoles, chillers, etc did not). We have
had 3 systems installed since the flood. So, they plan to grind up the
floor as close to the magnets as possible and move the consoles, chillers,
etc.as necessary. The whole thing terrifies me a bit.
Concerns:
1.
While there will be significant dust mitigation, including 1) heavy duty
vacuum systems attached to the grinders and 2) the magnets, consoles, etc,
will be wrapped in plastic, I am concerned not only about the dust, but also
tiny metal dust from the grinder disc getting into the magnets. Does anyone
have any experience or recommendation about this part?
2.
They've asked if they can use the handheld grinders closer to or under the
magnets. I am not sure if this is a good idea. A high rpm spinning metal
disk under the magnet??? How close is safe?
Any advice, suggestions, etc?
