First of all, with all the hazardous chemicals in an electronics
manufacturing shop, your subcontractor allows water to be consumed in their
shop???? Even with a pseudo "sports bottle"??? For employee health and
safety issues, I would strongly recommend that this practice be stopped.
Hazardous materials can be ingested, inhaled, and absorbed by the skin.
ANSI/IPC-A-610, in section 3.4.1, as a guideline, indicates that "There must
not be any eating, drinking, or use of tobacco products in the work area."
In ANSI/J-STD-001, in section 3.7, "Eating, drinking, and/or use of tobacco
products shall be prohibited in the workarea." for operating in a class 3
environment. While the hardware might not be damaged or effect reliability
by these practices, accidents with food and drink will happen which will
damage the hardware. Therefore it is a cause for concern which should be
remedied.
From a historical perspective, documents like MIL-STD-2000 prohibited
eating, drinking, and/or use of tobacco products from the workarea, citing
potential material contamination issues.
If I was your subcontractor, I would get all the food and drink off the
shop.

Subject: [TN] Drinking Water
As long as Steve has brought up the touchy subject of safety glasses I
thought I'd throw in the touchy question of drinking water on the line.
We work to J-STD-001 and flow that down to our subcontractors. We have a
subcontractor that has always allowed their operators to have a jug of
water at their bench. The containers they use are ESD safe and have a straw
out the top so they don't have to touch the top of the container where they
drink (unlike a sports bottle with a pop up top) .
Two questions, what is the problem with this approach and when the spec
refers to "drinking" does it mean water and why? (woops I guess that's
three questions)
Thanks,
Ken Bloomquist
