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?
