What safety concern is associated with looking into a black light during penetrant inspection?

• A. Temporary clouding of vision after exposure
• B. Permanent blindness
• C. No hazard
• D. Immediate eye pain

Answer: (A)

Looking directly into a black light during penetrant inspection can produce temporary visual disruption. The UV-A light from these lamps can overwhelm the eye briefly, causing afterimages or a foggy/cloudy vision that lasts for a short time after exposure. This is why the safety concern is described as temporary clouding of vision after exposure. It’s not typically permanent from a brief exposure, and while eye pain can occur with more severe or prolonged UV exposure, the common, expected hazard in this context is the transient loss of clear vision. Avoid direct viewing and use proper eye protection to prevent this temporary impairment.
