Laser
work and similar operations create intense
concentrations of heat, ultraviolet, infrared, and reflected light
radiation. A laser beam, of sufficient power, can produce
intensities
greater than those experienced when looking directly at the sun.
Unprotected
laser exposure may result in eye injuries including retinal burns, cataracts,
and permanent blindness. When lasers produce invisible ultraviolet,
or other radiation, both employees and visitors should
use appropriate eye protection at
all times.
Determine the maximum power density, or intensity, lasers produce when workers are exposed to laser beams. Based on this knowledge, select lenses that protect against the maximum intensity. The selection of laser protection should depend upon the lasers in use and the operating conditions. Workers with exposure to laser beams must be furnished suitable laser protection.

When selecting filter lenses, begin with a
shade too dark to see the welding zone. Then try lighter shades
until one allows a sufficient view of the welding zone without
going below the minimum protective shade.
