In the event of a spill, eyewashes should be used for at least how long?

Explanation:
Rinsing for a sufficient period ensures the contaminant is thoroughly washed away from the eye. The standard guidance is to use an eyewash for at least 15 minutes, giving enough time to dilute and remove residues from both eyes. Shorter rinses, like 5 or 10 minutes, may not clear all irritants, while much longer rinsing isn’t typically necessary for most spills. If irritation persists after 15 minutes, continue rinsing and seek medical attention. While rinsing, keep the eye(s) open and let a steady flow of lukewarm water wash across from the inner corner toward the outer edge to maximize cleaning.
