The most common type of radiation burn sustained by the cornea is due to excessive exposure to ultraviolet (UV) light. The UV radiation spectrum ranges from 100 to 400 nm. 

Most ultraviolet radiation is blocked by Earth s atmosphere, but some solar ultraviolet radiation penetrates the ozone and aids in plant photosynthesis and the production of vitamin D in humans. Too much ultraviolet radiation can burn the skin, cause skin cancer and cataracts, and damage vegetation. 

A. Ultraviolet (UV) Radiation (180 - 400 nanometer (nm), UV-A, B, C). The primary hazards from this wavelength range are damage to either the lens or the cornea of the eye. Long term low level and short term high level exposures can cause corneal and lens opacities (cataracts) or inflammation of the eye. UV radiation can also cause photokeratitis, which is sunburn of the cornea. The threshold for ultraviolet radiation skin burns is similar to that of the cornea.

Generates ultraviolet radiation causing a particular type of burn similar to severe sunburn. Molten metal resulting from arcing can penetrate, burn and lodge in the flesh. Ultraviolet radiation can also cause damage to sensitive skin and to eyes, e.g. arc eye in metal arc welding. 

Burns of the eye may result from chemical splashes and exposure to ultraviolet radiation as can occur with electric welding. It is vital that chemical burns be treated at once by irrigation with copious quantities of running water. 

The non-electrical safety precautions comprise protective clothing for the operator to prevent burn injuries from arc sputter and the ultraviolet and infrared radiation produced by the arc. A visor is used to protect the face, with an aperture fitted with a filter glass through which the operator observes the area. It is usually necessary to provide extract ventilation to remove fumes, and opaque or filter screens, arranged around the operator, to protect other people in the vicinity from ultraviolet radiation (see Fig. 16.2).
