I lost the original posts to reference regarding glassblower's eye
protection, the effects of long-term glassblowing on the eyes, and
handling/working with mercury in repairs..so I'll just add my
comments.

Effects of Long-term Glassblowing on the Eyes:
In addition to cataracts, Glaucoma is another main concern for glassblowers.
The test for it is quite simple and should be added to the glassblower's
annual eye exam.

Handling/Working with Mercury:
 -Inhaling Mercury Vapors: Mercury has no odor. It should be handled in
a well ventilated area, preferably a hood. One air change every 10 minutes
is the *minimum* ventilation necessary. When covered with water at room
temp., mercury emits no toxic vapor.
 - Mercury Spills: Poisoning can be caused by absorption through the
skin. In addition to thoroughly washing hands and face, there should
be no smoking or eating in the area. If hot mercury is spilled, the
area should be evacuated immediately until the mercury has had time to
cool.
 - Repairs: When at all possible, avoid working on mercury contaminated
glass. When it cannot be avoided, a few precautionary rules should
be followed. Due to the very toxic effects, no glassblowing by mouth
should ever be undertaken. Glassblowing may be accomplished by
using a squeeze bulb method instead of blowhose.


Just my 2 cents...
