in case of accidental contact with chemicals, how long should the eyes be flushed at the eyewash station?

In case of accidental contact with chemicals, the eyes should be flushed at an eyewash station for a minimum of 15 minutes. This flushing should begin immediately after exposure and continue thoroughly to dilute and wash away the chemicals. For some chemicals, longer flushing times may be needed—such as 20 minutes for more severe irritants and up to 60 minutes for certain penetrating corrosives. It is also important to hold the eyelids open and roll the eyeballs during flushing to ensure thorough irrigation. Medical attention should be sought promptly after flushing. These practices are consistent with safety guidelines provided by occupational safety organizations and emergency protocols.
