What is an appropriate first aid measure for arc eye?

• A. Cover eyes, seek medical care, avoid further exposure
• B. Rinse eyes with water for several minutes
• C. Continue welding and monitor
• D. Apply ointment to the eyes

Answer: (A)

Arc eye is caused by UV radiation from the welding arc, so the immediate goal is to limit further light and heat exposure to the eyes while getting proper medical evaluation. Covering the eyes with a clean, loose shield or dressing protects the cornea from additional irritation and reduces pain from light sensitivity, rubbing, and wind. This protection helps prevent more damage until a clinician can assess and treat the injury. Moving away from the welding area stops further exposure, and seeking medical care promptly ensures appropriate treatment and monitoring. Avoid continuing to weld because that would worsen the exposure. Ointment is not used as first aid for arc eye because it can blur vision and complicate examination; evaluation by a professional is the priority. If there were a chemical splash, irrigation with clean water could be helpful, but the key action remains shielding the eyes and obtaining medical care.
