Which maintenance item is specified as part of upkeep for portable eyewash stations?

• A. Replace the filter
• B. Recalibrate the meter
• C. Change the solution
• D. Replace the nozzle

Answer: (C)

Keeping the solution fresh in portable eyewash stations is essential because over time the liquid can become contaminated or lose its effectiveness, reducing its ability to properly rinse the eyes during an incident. Replacing or refreshing the solution helps ensure the unit delivers clean, effective irrigation and meets safety guidelines or manufacturer recommendations. Other maintenance tasks listed aren’t typically part of standard upkeep for portable units—there aren’t filters or meters to recalibrate in most designs, and replacing the nozzle is only necessary if it’s damaged or obstructed, not as a routine requirement. Regular inspections should still verify that the unit is unobstructed and functioning when activated, with the solution updated according to the manufacturer’s schedule.
