[R-390] Maybe OT Tungsten Disulfide issues

[KR4HV]

Here is the MSDS Data Sheet.

I am no chemist or doctor but from the MSDS sheet it doesn't appear
generally to be a life threatening compound from minimal casual exposure
when handled with, say the same procedures as for painting.

Cautions on the sheet are about the same as any other household type
chemical, even less stringent.

I'm open to any real experience and knowledge dealing with this substance.

It is worse than radioactive materials!  Although I can see it, I have not
been able to handle it without major cleaning issues.

It spreads all over the place, and this isn't even the nano version.

I try to "contain" it, but it always spreads.

I do not have a glove box.

What has everyone been doing to avoid it going everywhere and getting
tracked all over.

I've been using paper towels soaked with alcohol, nitrile gloves, use Q-Tips
to dip in alcohol then the powder.  It is loose.

Help!
