During a monthly inspection, which maintenance action is specified for portable eyewash stations?

• A. Clean the nozzle
• B. Change the solution
• C. Replace the unit
• D. Recalibrate the flow rate

Answer: (C)

monthly checks are about ensuring a portable eyewash can deliver a reliable, clean stream immediately in an emergency. Portable units have a limited service life and their components can degrade or become contaminated over time. Replacing the unit during a monthly inspection guarantees that the device you’re relying on will provide the proper flow and a fresh, uncontaminated solution path, which is essential for effective irrigation of the eyes.

Cleaning the nozzle helps prevent clogs, but it doesn’t address the overall condition of the container, seals, or the integrity of the flow path, and it may not ensure the solution is fresh and uncontaminated. Changing the solution can be important if the unit uses a replenishable reservoir, but many portable units are designed so that replacement is the safer, more reliable approach to maintain readiness and compliance. Recalibrating the flow rate isn’t typically an option for these portable designs, where the flow is set by the unit’s hardware rather than by user calibration.

So, replacing the unit ensures the eyewash remains ready, compliant, and capable of delivering a proper flush right away.
