Et al,

At the most recent meeting of the ANSI/ISEA Z358.1 Standard committee meeting, we had represenatives from D-CHAS and CSHEMA make presentations. Most informative.The Standard is in its usual 5-year review process. The most recent one is 2014.

Issues that come up are testing that water can come out of a fixed plumbed facility and to flush bacterial and other sludge out. While bacteriology might be used, it seems difficult and not cost effective. Potable water is "water suitable for drinking" which means in testing by many state Health Departments to be <1 E. Coli colony forming units.

So, opening the taps and seeing that water flows and it is not visibally full of gunk might do. One or twice a year, the full Flushing should likely be done. That would mean for emergency showers, 15 minutes at 20 gallons/minute (note that floor drains are not part of the Standard as they are in plumbing codes for various jurisdictions).

This is not professional advice, but a bit of common sense (the least common thing in the world).

I would consult with a PhD, CIH or a Safety Engineer to get a professional opinion.

We have started using a system from Bradley (Menomonee Falls, WI) which has a self-contained reservoir mounted on a wheeled receiver cart. The water is filtered and changed out on a two-week basis (I think) by the company. It=E2=80™s a service we pay for, but that's industry for you. I don't know the purchasing details. These may be available from safety supply houses and there may be other brands.

The mobile station gets around the risk of debris coming from the pipes, water overshoot in the eyewash fountains onto the floor, and the frigid water we have most of the year in Wisconsin. Of course, that last bit won't be a problem in San Antonio. The cart can be rolled and placed near the work so that an affected person doesn't have to wander around the lab blindly, trying to remember where the nearest eyewash station was.

Subject: [DCHAS-L] Question about eyewash / safety shower testing

Greetings,

I have a quick question about eyewash/safety shower testing. I live in San Antonio, Texas. On occasion we have water restrictions. Has anyone come up with a way to reduce, reuse, or recycle the eyewash/safety shower water? I am curious to know how the Universities in California handle this.

Best,
