FYI a better design is this one. The graduated volume marking and powered pump make it easy to use and empty. Remember in addition to the monthly flush a periodic flow test is needed that measures rate of water delivery (20 gpm).
The other problem with the bag / shower curtain type testers is that you cannot measure the diameter of the spray pattern easily. It needs to be 20 in diameter at 5 ft. from the floor. With a rigid system it's possible to set the funnel at that fixed height and observe the over spay to verify the spray pattern diameter.
Just some suggestions.

They do make safety shower testing kits, on wheels even. See http://www.enconsafety.com/en/parts-and-accessories/testing-equipment/mobile-shower-test-assembly/stu1,%20stu2/, though I prefer that the chute have a rod on it because I am short.

Our renovated building came on line last year and regular eyewash flushing didn't start until this fall. It's a small department (8 labs and 4 prep rooms) and the eyewash configuration is such that flushing is not convenient. The facilities crew configured a wheelbarrow with various hoses attached to catch the water but it's still a pain, and now they are struggling to find enough people-hours to complete the task on a weekly basis. There is talk of it becoming part of the CHO position (that's me...)
I will say that the water coming out of the new units was disgusting (gunk and smell) for a while. I think it's improving with regular flushing, but it gives one pause when considering putting one's face in there.

Hmmm... just curious, how do you do weekly flushing of eyewashes as per ANSI standard? And the shower flushing and flow testing?
We did not do flush units on a new science building that came online 3 years ago. This is all new to me.

Subject: [DCHAS-L] Shower/Eyewash Station Audible and Visible Alarms
During a recent lab renovation, the contractor presented to us wall mounted shower/eyewash stations that have both an audible alarm and visible strobe when activated. The unit also has the ability to communicate back tot he BMS system upon activation. While this all sounds fine and dandy, it has raised a few questions on my end.
1. Is this a new standard being used for installations? I definitely see some practical purposes for this in order to alert others that an emergency has occurred, but I have not come across this before.
2. This raises some design dilemmas on our end.
A. We are installing these as flush mounted systems, so the units strobe and audible alarms would be above the drop ceiling (or we would have to relocate the alarm indicators).
B. For obvious reasons, the contractor was originally spec-ing out installation on walls without electrical just for cost and ease of plumbing. If alarms are necessary, power must be ran to the units, thus increasing scope and cost.
In general, I was just curious as to what kind of new installs other universities were currently putting in place.
