ANSI/IFSEA Z358.1 requires weekly testing.
4.6.2 Plumbed emergency showers shall be activated weekly for a period long enough to verify operation and ensure that flushing fluid is available.
5.5.2 Plumbed eyewashes shall be activated weekly for a period long enough to verify operation and ensure that flushing fluid is available.
B7. Weekly Activation for Plumbed Emergency Eyewash and Shower Equipment
The intent of the weekly activation to be conducted on plumbed emergency eyewash and shower equipment is to ensure that there is a flushing fluid supply at the head of the device and to clear the supply line of any sediment build-up that could prevent fluid from being delivered to the head of the device and minimize microbial contamination due to stagnant water. The duration of this test is dependent on the volume of water contained in the unit itself and all sections of pipework that do not form part of a constant circulation system (also known as “dead leg” portions). Water in these sections is stagnant until a flow is activated by opening a valve. The goal is to flush out stagnant water in the dead leg completely. Where mixing valves are used, both the hot water and cold water supplies to the valve must be considered.

We have integrated eye/shower stations. Our facilities staff inspects the eye washes weekly and the showers are monthly. I’ve never noticed them timing the test. Also, I’m not aware of an inspection test time requirement. If there is one, please let me know where to find it.
Thank you,

Trying to get the best practices here.
How does your institution interpret ANSI 358.1-2014 and safety shower testing?
I know eyewash stations are 5 minutes per week.
What is the frequency you use for testing showers and the duration?
Thanks in advance.
