List,

After your experience with the Pepsi bottles that
is a reasonable thought.

However, I still have several pounds of WS powder
stored in ordinary zip lock bags which have shown no degradation since I
purchased it many months ago.

It is inherently safe with ordinary precautions.  I filled many small zip 
lock bags with it and
I did get some on my fingers but it washed off easily with soap and water. 
Most
of the time I used cheap latex gloves as I was measuring out many bags.

The reason one doesn’t want to breathe it is the
same reason ones doesn’t want to inhale coal dust or fine cotton particles.

If any of the above gets into your lungs it stays
there.  Enough over a long period of time
will lead to a form of “Black Lung” problems.

Because of the fineness of the particles, when I
was lifting it out to the smaller bags, was that I would get almost vertical 
side
walls when lifting it out with a tiny spatula.

Yes, if you’re going to have a big sneeze or a
fast airflow that is not good around WS powder.  But it is perfectly useable 
without a respirator.

One uses alcohol as a delivery system that
evaporates leaving the WS on the part one wants lubricated.

Reasonable care of use yes, fear no.

Regards,

Perrier
