What type of radiation can cause damage to the eyes from an electric welder's arc?

Infrared light
Invisible radiation
Ultraviolet radiation
Sensible light

The correct answer is: Ultraviolet radiation

Ultraviolet radiation is the type of radiation that can cause significant damage to the eyes from an electric welder's arc. When welding, the intense light produced can emit high levels of ultraviolet rays, which are invisible to the human eye yet capable of causing a condition known as "arc eye" or photokeratitis. This condition is akin to having a sunburn on the cornea and can lead to pain, blurriness, and increased sensitivity to light. In the context of welding operations, proper eye protection, such as specialized welding goggles or face shields that filter out UV rays, is essential to prevent eye injury. Understanding the specific hazards associated with welding activities, including the emission of ultraviolet radiation, is a crucial aspect of maintaining safety in such environments.
