What is the correct first aid treatment if only one eye has received a chemical burn?

When treating a chemical burn to the eye, it is essential to flush the affected eye properly to remove the irritant and minimize damage. Flushing the eye outward from the eye is the correct approach because it helps prevent the chemical from entering the unaffected eye, reducing the risk of cross-contamination and further injury.

In a chemical burn situation, the objective is to wash away the chemical quickly and effectively. Flushing outward ensures that any harmful substances are directed away from the other eye, protecting it from exposure. Typically, a gentle stream of clean water or saline should be used for an extended period—usually at least 15 to 20 minutes.

Other options provided do not align as effectively with best practices for this situation. For example, flushing inward toward the nose could risk introducing the chemical to the other eye. While using saline solution is a good practice, it is crucial to ensure that the flushing direction prioritizes safety for both eyes, making outward flushing the preferred method. Applying a bandage may not be appropriate immediately after a chemical burn without proper washing first, as bandaging can trap the irritant against the eye.
