If chlorine enters the eyes, how long should you flush with running cool water?

In the event that chlorine or any caustic substance gets into the eyes, it is crucial to flush them with running cool water promptly and thoroughly to minimize damage and irritation. The recommended duration for flushing the eyes is at least 15 minutes. This duration allows enough time for the water to help dilute and remove the chlorine from the eye surfaces, reducing the risk of serious injury or lasting effects.

Flushing the eyes effectively involves using a gentle stream of cool water, which helps to soothe the eyes and rinse away the irritant. Although shorter or longer flushing times may be suggested in different guidelines, 15 minutes is a widely accepted standard in emergency response practices, aligning with occupational safety recommendations. This recommendation ensures that the chemical is thoroughly washed away, providing adequate time for relief and minimizing potential harm to the eye tissues.
