Static Dissipating Screen Overlays

Commercial conductive overlays may be used to drain CRT screen static in nonhazardous locations. The ground connection on such overlays must be made secure to prevent shocks. 

Note Powder is a generic term for subdivided solid material, comprising pellets, granules and dust. Pellets have a diameter greater than 2 mm (U.S. No. 10 Standard Sieve) and typically above 3 mm. Granules have a diameter between 0.42 and 2 mm, although granular powders typically contain dust. Dusts have a diameter less than 0.42 mm and as low as I pm. Suspensions of particles smaller than I pm are known as fumes.
