If a chemical spills in the eye, how long should you flush with running water?

• A. 20 minutes
• B. 2 minutes
• C. 60 minutes
• D. 5 minutes

Answer: (A)

Immediate and continuous irrigation is essential when a chemical splashes into the eye. Start flushing with clean running water right away and keep the eyelids open so water can reach all eye surfaces. If possible, direct the flow from the inner corner toward the outer edge to help minimize contamination of the other eye. Continue flushing for about twenty minutes; this minimum duration helps dilute and remove the chemical and reduces tissue damage. After irrigation, remove contact lenses if present and seek urgent medical care, especially if the chemical was strong or irritation persists. If you can check pH, aim for neutral, but don’t delay irrigation to do so. Longer irrigation may be needed for certain substances under medical guidance, but twenty minutes is the standard starting point.
