DU Counterweights Sample MSDS



For those radsafers interested,

As was noted, not all DU aircraft counterweights have
the cadmium coating (or are used in the procured 
manufacturers form--if so 'cladded', actually not
much more than a layer of paint).

Since the older they get, the more likely they will
be machined/reshaped/divided (and hopefully repainted!),
the following sample MSDS precautions should be noted
(remembering that every manufacturer of counterweights
may have differences in their specific MSDSs):
