Employers must provide eyewash facilities with at least how many minutes of continual rinse fluid?

• A. 5 minutes
• B. 10 minutes
• C. 15 minutes
• D. 30 minutes

Answer: (C)

The important idea here is that an eyewash must run long enough to thoroughly dilute and wash away contaminants from the eyes. Safety standards require a continuous flow for a minimum of 15 minutes, using tepid water, so you have enough time to rinse out irritants or chemicals and reduce the chance of tissue damage. Shorter rinses—like 5 or 10 minutes—may not remove all contamination and can leave irritants behind. A longer rinse, such as 30 minutes, would still meet the requirement, but the essential minimum you must provide is 15 minutes.
