What is the minimum duration of eyewash fluid that must be available for continual use?

• A. 5 minutes
• B. 15 minutes
• C. 25 minutes
• D. 60 minutes

Answer: (B)

Eyewash duration is the critical factor here: the minimum time equipment must provide continuous irrigation is 15 minutes. This length of flow ensures there’s enough time to flush out chemicals or debris from both eyes, diluting and removing the irritant and reducing the potential for ongoing injury before medical evaluation. Shorter irrigation times may not sufficiently cleanse the eyes, while longer irrigation isn’t required by the standard, though nothing prevents using longer rinsing if needed. The 15-minute requirement is a widely adopted safety benchmark to guarantee a meaningful first-aid response after an eye exposure.
