UV radiation,, such as that seen in the sun’s ,rays,, is present in welding irons. Prolonged exposure to ,UV radiation can, cause skin cancer. Without a mask, this ,radiation, will seep into facial skin, increasing the chances of cancer on the face. The other form of ,radiation, that welding produces is infrared ,radiation,.
Helmets, and Arc ,Rays, Q: What are the two forms of ,radiation, given off by the welding arc? A: The two types of ,radiation, are Infrared (IR) and ,Ultraviolet, (,UV,) ,radiation,. IR ,radiation can, cause retinal burning and cataracts. IR ,can, usually be felt as heat. ,UV radiation,, which cannot be felt, ,can, cause an ,eye, burn known as "Welder‘s Flash."
Finding the best welding ,helmet, is critical for your ,safety,. A welding ,helmet, is going to protect your ,eyes, from the ,UV rays, that come off of the arc. These ,UV rays can, cause a lot of issues if you’re not wearing a protective welding ,helmet,. There are many options available in the category of welding ,helmets,.
Exposure to artificial ,UV, sources ,can, cause severe ,eye, damage. Temporary damage often heals within a couple of days. Permanent damage usually only occurs right away with severe exposure. Any exposure, however, adds to the cumulative impact ,of UV light, on ,eyes,. What ,Effect, Does ,UV Light, Have On ,Eyes,?
This is one of the most popular welding ,helmets, available. ,The Safety, BH3 is fitted with an auto-darkening lens that has a shade range of 9-13 and an EN379 rating of 1/1/1/1 for optical clarity, light diffusion, luminous transmittance variation, and angular dependence. This ,helmet, protects your ,eyes, from ,radiation, and ,ultraviolet, light.
Helmets, also ,can, reduce the need for wearing secondary ,safety, lenses under the shield. Although autodarkening lenses do not darken until an arc is struck, if the ,helmet, is ANSI-compliant, it will already block out ,UV, and IR ,rays, whether the ,helmet, is on or off. ,Helmets, that take a millisecond or less to change shades are recommended. 2
The higher degree of scattering of these ,rays, makes the cloudless sky look blue. 3. The ,eye, is not very good at blocking blue light. Anterior structures of the adult human ,eye, (the cornea and lens) are very effective at blocking ,UV rays, from reaching the light-sensitive retina at the back of the eyeball.
