All the main types of welding produce ultraviolet, visible spectrum, and infrared radiation. Since reflected light can also carry radiation, your eyes can be damaged from the arcs of other welders, too. Ultraviolet radiation (UVR) in particular gets absorbed in the lens and cornea and leads to swollen, painful eyes.

intotwocategories:
 1. The dangers of burns, damage to the eyes,
electric shock and possibly explosion.
 2. Insidious hazard, with possibly both short
and long-term health effects from fumes and
gases. The latter problem is particularly
acute with some types of welding such as
argon arc (TIG), metal inert gas (MIG),
electron beam, resistance, laser and plasma-
arc.
Introduction:

4.  The hazards associated with the welding process depend
on the type of welding, the materials (base metals, surface
coatings, electrodes) to be welded, and the environmental
conditions (outside or in a confined space, for instance).
 The main actinic component of welding is UVB which is
produced mainly by arc welding and to a lesser extent by
gas welding.
 Exposure to UVB has been associated with many ocular
conditions such as cataract, which is the major cause of
blindness in most parts of the world including South
Africa. Acute exposure to UVB results in acute kerato-
conjunctivitis, a condition also known by various names
such as welding flash, flash eye, photophthalmia, arc eye
or actinic ray photokeratitis.

 Thermite welding.
 Gas welding.

Ultraviolet radiation.

10. Safety measures in the
prevention of welding eye
injuries:
 Always wear safety glasses with top
and side protection under your
welding helmet.
 Be sure eye protection devices are
not damaged or missing parts and
be sure they fit properly.
 Use the correct shade of filter in
your welding helmet or goggles.
 Welding areas should be isolated
from other work areas by partitions
or curtains designed to absorb
harmful welding rays.

11. TypesofProtectiveDevices:
 Spectacles (safety glasses).
 Goggles.
 Face shields.
 Welding Helmets and hand shields.

12. CONCLUSION
 Always choose welding helmets and eyewear that meets
the requirements to ensure proper vision protection.
 Maintain welding helmets and eyewear in good
condition—inspect them regularly and replace parts as
needed.
 Clean eyewear as needed according to the
manufacturer's recommendations, and after use by
others.
 Always read, understand, and follow the manufacturer’s
instructions.
 Remember: The eyewear you choose, and wear is your first
line of defense in preventing eye injury and blindness.
