What is the danger of being exposed to ultraviolet light given off by arc welding?

Exposure to ultraviolet (UV) light during arc welding can lead to both flash burns to the eyes and burns to exposed skin. This is due to the intense UV radiation emitted during the welding process. Flash burns, often referred to as "arc eye" or "welder's eye,” is a painful condition where the cornea becomes inflamed after being exposed to UV light, leading to symptoms like redness, discomfort, and tearing.

In addition to eye injuries, the skin can also be harmed. Welders frequently experience burns on any unprotected skin due to direct UV exposure, which can lead to temporary skin irritation and can increase the risk of long-term skin damage with repeated exposure.

Therefore, the correct answer encompasses both the potential for eye damage and skin burns, highlighting the multifaceted risks of UV exposure during arc welding. Understanding these dangers is essential for implementing effective safety measures, such as wearing appropriate protective gear like goggles and protective clothing designed for welders.
