What can IR cause?

What can IR cause?

• A. Retinal burning and cataracts
• B. Only warmth on skin
• C. No health effects
• D. Taste changes

Answer: (A)

Infrared radiation from welding arcs can cause serious eye injuries in addition to just warming the skin. IR penetrates tissues and can heat and damage the retina, leading to permanent vision problems, and long-term exposure can contribute to cataract formation in the eye lens. That’s why retinal burning and cataracts are a real hazard from IR. While you might feel warmth on the skin, the eye risks are the critical concern, and statements claiming no health effects or unrelated effects like taste changes don’t fit. Proper eye protection that filters IR and avoiding staring at the arc are essential safeguards.
