I sprung for a new Zip-Loc bag. The plastic bag is important. The organic vapor cartridges don't particularly care if you are breathing the air that is passing through them, or if they are just grabbing any contaminants drifting their way. With the advent of Richard Wolbers's new methods in the cleaning of paintings, I find myself using UV light examination even more frequently during a cleaning. Since we make our collective livings from our eyes, protection of our organs of sight should be a priority.
Ultraviolet radiation damages the eye's lens and retina.
Using an ultraviolet light in the dark tricks the iris into dilating, admitting lots of UV into the eye. In my fit of health consciousness, I added a couple of pairs of UV-absorbing goggles to my respirator cartridge order. Oddly enough, since mailing off that order, I have heard fewer complaints from my liver and common sense. If you have been thinking about your health and safety, and have had any good ideas, let me know.
