Which of the following describes the correct performance of portable eyewash stations?

• A. Flow 0.4 gallons per minute for 15 minutes
• B. Flow 0.4 gallons per minute for 5 minutes
• C. Flow 1.0 gallons per minute for 15 minutes
• D. Flow 0.2 gallons per minute for 15 minutes

Answer: (A)

Portable eyewash stations are designed to deliver a continuous flow of at least 0.4 gallons per minute for a minimum of 15 minutes. This combination ensures enough water volume and time to flush eyes and remove irritants effectively. The description matching 0.4 gpm for 15 minutes aligns exactly with that requirement, so it is the correct performance. The option with the same flow for only 5 minutes reduces the rinse duration below the required minimum and wouldn’t meet the standard. The option with 1.0 gpm for 15 minutes technically satisfies the minimum, but the standard specifies a minimum flow of 0.4 gpm for 15 minutes, so the description of the exact minimum is the most appropriate. The 0.2 gpm option falls below the required flow and would not meet the standard.
