The conductive foam is only about static when first inserting
the EPROM to the eraser. If the UV light has been on for
some time, it is unlikely to have any static on surfaces exposed
the the UV light. UV erases static just as it does EPROMs.
For static handling precautions always make sure to touch the
surface before picking up or putting down the IC. Although,
it is not desired from a contamination point of view, one
shouldn't touch the leads of an IC, the best Faraday shield
is enclosing the IC in your fist. I've used this method for handling
such sensitive parts as 4051s and 4052s. If your hands are freshly
cleaned, you won't have much oil and salts on your skin.
From a manufacturer point of view, one should only move an
IC from point A to B in a static safe enclosure.
