What is a potential hazard when using ultraviolet lights for inspection?

Using ultraviolet lights for inspection poses a significant risk of eye damage. Ultraviolet radiation can lead to various eye injuries, including photokeratitis, also known as "welder's flash," and long-term effects such as cataracts. This risk is particularly pertinent in liquid penetrant testing, where the intensity and duration of UV exposure can be substantial.

Safety measures, such as wearing proper protective eyewear that can filter out UV radiation, are essential to mitigate this hazard while ensuring that inspectors can perform their tasks without compromising their vision. Other risks, such as electrical shock or skin burns, while they may exist in certain scenarios, are generally not as directly associated with UV light specifically used for non-destructive testing applications. Fire hazards could be more related to the materials being inspected or the presence of flammable substances but are not inherent to the use of UV light itself.
