The employer shall ensure that each affected employee uses eye protection that provides side protection when there is a hazard from flying objects. Detachable side protectors (e.g. clip-on or slide-on side shields) meeting the pertinent requirements of this section are acceptable.
Selection of shade numbers for welding filter. Table E-1 shall be used as a guide for the selection of the proper shade numbers of filter lenses or plates used in welding. Shades more dense than those listed may be used to suit the individual's needs.
Table E-1 - Filter Lens Shade Numbers for Protection Against Radiant Energy
|Welding operation||Shade number|
|Shielded metal-arc welding 1⁄16, 3⁄32, 1⁄8, 5⁄32-inch diameter electrodes||10|
|Gas-shielded arc welding (nonferrous) 1⁄16, 3⁄32, 1⁄8, 5⁄32-inch diameter electrodes||11|
|Gas-shielded arc welding (ferrous) 1⁄16, 3⁄32, 1⁄8, 5⁄32-inch diameter electrodes||12|
|Shielded metal-arc welding 3⁄16-, 7⁄32-, 1⁄4-inch diameter electrodes||12|
|5⁄16-, 3⁄8-inch diameter electrodes||14|
|Atomic hydrogen welding||10-14|
|Torch brazing||3 or 4|
|Light cutting, up to 1 inch||3 or 4|
|Medium cutting, 1 inch to 6 inches||4 or 5|
|Heavy cutting, over 6 inches||5 or 6|
|Gas welding (light), up to 1⁄8-inch||4 or 5|
|Gas welding (medium), 1⁄8-inch to 1⁄2-inch||5 or 6|
|Gas welding (heavy), over 1⁄2-inch||6 or 8|
Employees whose occupation or assignment requires exposure to laser beams shall be furnished suitable laser safety goggles which will protect for the specific wavelength of the laser and be of optical density (O.D.) adequate for the energy involved. Table E-2 lists the maximum power or energy density for which adequate protection is afforded by glasses of optical densities from 5 through 8. Output levels falling between lines in this table shall require the higher optical density.

|Intensity, CW maximum power density (watts/cm2)||Attenuation|
|Optical density (O.D.)||Attenuation factor|
