Which type of eye wash station must be checked and flushed most often

Eye wash stations, regardless of type, should be checked and flushed regularly to ensure they are functioning properly and provide effective emergency eye irrigation. However, the frequency of flushing may depend on the specific type of eye wash station. The two main types are plumbed (connected to a water source) and self-contained (contain their flushing fluid).

1. Plumbed Eye Wash Stations:

• These are connected to a continuous source of water.
• They should be activated weekly to flush out sediment and prevent the buildup of contaminants.
• ANSI (American National Standards Institute) recommends a weekly activation for plumbed eye wash stations.

2. Self-Contained Eye Wash Stations:

• These units contain their own flushing fluid, often in sealed cartridges or containers.
• They should be checked regularly to ensure the fluid has not expired.
• Flushing should be done according to the manufacturer's guidelines, which may vary but often includes a monthly activation.

In summary, while both types of eye wash stations require regular checks, plumbed stations typically need more frequent weekly flushing to prevent stagnant water and sediment buildup. Always follow the manufacturer's recommendations and relevant safety standards for maintenance procedures.
