During welding, exposure to ultraviolet light can lead to which condition?

During welding, exposure to ultraviolet (UV) light can indeed lead to both welding arc eye and skin burns, making “Both welding arc eye and skin burns” the most comprehensive and correct choice.

Welding arc eye, also known as photokeratitis, is an eye condition caused by overexposure to UV light, which can occur during welding. This condition is similar to a sunburn but affects the cornea, resulting in pain, redness, and blurred vision. It often occurs when a welder does not use proper eye protection such as masks or helmets equipped with suitable filters.

Similarly, skin burns can occur from the UV radiation emitted during the welding process. The skin can suffer from burns if exposed to intense UV light without adequate protective clothing or barriers. Welders are at risk of developing second-degree burns or even more severe damage if protective measures are not taken.

This dual risk emphasizes the importance of safety practices in welding to protect both the eyes and skin from harmful UV radiation. Hence, the comprehensive nature of option C accurately reflects the potential dangers associated with UV exposure during welding activities.
