Re: Decon of old rusty material
Mark,
Depending upon how old, rusty and contaminated the object is there are
different methods available.
The most conservative as one of our colleagues has suggested is to
decon the material in a tent or glove bag. Provided such a control is
in place, with adequate negative ventilation, you can feel free to
utilize the electric drill with a wire brush. Without the ventilation
controls I would not approach it with such a method.
Something that has worked very well for me is "elbow grease" applied
to a "3M" green scrub pad and a liberal application of decon foam
(soap and water). There are numerous suppliers out there with decon
foams available that may suit your application.
The one thing I strongly warn against is disturbing the layer of
corrosion with a high speed drill or sander. You have no way of
knowing what is under the corrosive layer, nor how the materials may
disperse due to the air currents generated.
Respectfully,

One of my sites in northwestern NY is
contaminated with uranium. I'm going up there
week after next to try a test decon of metal
machinery.
My plan is to use a wire brush attached to a
hand drill. My plan is to use the brush with
some soap and water.
I was wondering if any of the more experienced
people out there had any "pearls of wisdom"
with this method and could offer some advice.
Also if someone has some better ideas please
tell.
