After a factory worker’s eyes are splashed with a strong acid and sterile saline is not available, which action is correct?

• A. Mix baking soda with water and irrigate his eyes
• B. Flush both eyes with an alcohol-based solution and transport
• C. Irrigate both eyes continuously for 20 minutes with plain water
• D. Neutralize the acid chemical in his eye with an alkaline chemical

Answer: (C)

Immediate, continuous irrigation of the eyes with clean running water for about 20 minutes is the best course of action when a strong acid splashes the eye and sterile saline isn’t available. The aim is to quickly dilute and wash away the chemical to minimize tissue damage, and plain water keeps irrigation safe and readily accessible in most settings.

Avoid attempting to neutralize the acid with another chemical, such as baking soda, because the neutralization reaction can generate heat and worsen injury. Also, do not use alcohol-based solutions, which can irritate the eye and are not appropriate for chemical splashes. If a contact lens is present, remove it only if it’s safe to do so during irrigation. After irrigating for the full 20 minutes, seek urgent medical care and continue to protect the eye from further injury.
