Hi Kenny & All -

We had a discussion on this a couple of months ago, which you may want to
dig out of TechNet archives.  Realize that the rules prohibiting eating,
drinking or use of tobacco in production areas evolved back in the 1950's,
and perhaps before.  The rules were implemented to protect both the product
and the employees, and they are not necessarily peculiar to the electronic
industry.

There are several issues involved with "drinking water" on the production
line:

First, the purity of the water itself.  I've had the experience of having a
number of water samples analyzed over the years, ranging from tap water to
the purchased "pure mountain spring" water.  Have found quite a number of
interesting organic and inorganic things that I wouldn't pour on an
electronic product.  This becomes even more important if you're running a
"no clean" operation and trying to protect the product from being
contaminated in your shops.

Second, the risk of ingestion of contaminated fluids.  A lot of folks don't
have too great a sense of personal hygiene, in spite of having been schooled
in the subject since they were toddlers.  It's tough enough to get them to
"Wash Hands Before Eating" that mid-morning break Twinkie, or whatever.
I've seen some of those bottles get pretty grimy, including the mouthpiece.
Have also seen folks snap the drinking cap open with a grimy hand, then
stick it in their mouth.  Drinking fountains in or near the area are a whole
lot better solution - protects the people and the product.

Third, things like this have a habit of creeping into other things.  Two
weeks ago, I was working an assignment for one of our small local shops that
allows bottled drinking water to be consumed on line.  I happened to notice
an oddly colored bottle of water and asked the young lady who was drinking
from it just exactly what it was.  She proudly showed me the label which
read, "Peach Water".  Turns out this stuff had a fair load of sugar,
flavoring and some, as yet unidentified, bacterialogical stuff.

While I'm strongly in favor of realistic work rules, I continually remind
myself that the rules also have to protect the primary goals of running a
factory: efficient production; reliable output; and profitability.  The
rules also have to protect the health and safety of its employees.

In another post, someone raised the question of people with a Walkman
plugged in both ears, oblivious to their surroundings.  Here's my nickles
worth on that item:  Ever see one of these folks just continue to sit there
when the Plant PA system blares out a warning for a tornado, fire or gives
other significant information?  Ever stop to consider how much of their
concentration is on the product, vs. how much is on the entertainment?  Ever
seen one of these folks obviously keeping time to the music beat with the
movements of their soldering iron tip?   My vote has to be "No" on the
Walkman, as well.

Regards - Kelly
