In 2002 a lady in our plant was opening boxes of pink poly bags and then
noticed that she had a tingling on the ends of her fingers, then a rash
to her first knuckles, second, third, wrists, elbows, shoulder!!  We had
to send her to E.R.  EHS quarantined ALL pink poly bags we were buying
from about 6 or 7 suppliers and gave us a sample of the bag type that
affected her and samples of all the rest. Using FTIR we were able to
separate the sheep from the goats, as it were.  Two or three types of
bags were using a particular amine additive as the hydroscopic material
to induce the formation of the thin layer of water molecules on the bag
that acts as the actual static charge deterrent. 

We purged all those bags and she never had a problem again.  And, no, I
do not know the name of the company that produced the bags.

Subject: [TN] ESD Cap Plugs

Dear TechNet:

There has been discussion on the use of "pink poly" for ESD prevention
on flight hardware. An expressed concern has been the chemicals added to
the surface of pink poly can potentially contaminate our products with
the residue pink poly leaves behind. I have posted a picture of one of
our boxes which have both the pink poly and black ESD style of cap
plugs. What are any of your experiences with contamination associated
with using pink poly? As always, thanks,
