How Often Does OSHA Recommend Flushing Eyewash Stations?

Activate permanently plumbed eyewash units weekly to ensure proper operation.

OSHA recommends flushing plumbed eyewash stations on a weekly basis to ensure that they are in proper working condition and ready for immediate use in case of an emergency. This weekly flushing should be conducted using the manufacturer's instructions to ensure that the eyewash station is providing a sufficient flow of water and that the water is clean and free of contaminants. Self-contained or portable eyewash stations only require visual inspection and do not need to be activated weekly. 

In addition to the weekly flushing, OSHA also recommends activating the eyewash station monthly to ensure that it is working properly and to prevent stagnation of water in the system. During the monthly activation, the water should flow for at least three minutes to flush out any sediment or buildup that may have accumulated in the pipes.It's important for employers to document these regular flushing and activation procedures and to keep records of any maintenance or repairs performed on the eyewash station. Regular maintenance and inspection of eyewash stations are critical to ensure that they are functioning properly and in compliance with OSHA regulations.
