Section 4.5.6; B6 of the Z358.1 requires delivery of tepid water. Alan mentioned that the definition of tepid water was in the Appendices, however I saw somewhere that the temperature range was moved to (or included in) the Definitions section. I don't have a copy of the standard so I will defer to him on that. I assume that the word "tepid" appears in the Standard itself either way, is that right, Alan?

The 2003 and later versions of the International Plumbing Code (IPC) require the use of ANSI/ISEA Z358.1 compliant equipment when eyewash or showers are required (around caustic or corrosive materials).. See, for example, https://safetyequipment.org/wp-content/uploads/2015/05/EWS-Guide-Feb_2015.pdf So this incorporates the tepid requirement. And even if your state has not adopted the IPC, it is obviously a best practice issue when you think about potential liability.

Most state and local governments have adopted the IPC but, based on personal experience. less than 5% of people who purchase eyewash or shower units from us opt for the the thermostatic mixing valve even though their local codes would apparently require it. TMV's can cost more than the eyewash unit itself so I understand why people balk, but I've also seen people try to keep stating under a safety shower in the wintertime with ice cold water pouring over them when they are in shock or are injured.

For code adoption see https://www.iccsafe.org/wp-content/uploads/Code_Adoption_Maps.pdf and click on IPC.

I have a question about eyewashes.

Do you have to regulate the temperature on the eyewash? We are in California, and we are installing a new eye wash.

I thought there were some recommendations/codes?

Thank you so much.,,,,,

Eric et al,

I am a voting member of the ISEA (International Safety Equipment Association) EWS (Eyewash and Shower) Product Interest Group who periodically (every 5 years) revise the ANSI/ISEA Z38.1 Standard. We will be meeting on November 18, 2019 to go over the final potential changes to the Z358.1 2019 revision..

The issue of activation and testing is frequently brought up by those who utilize the Standard.

If you have results from the D-CHAS group, I'd like to receive them before the morning of November 18, 2019 so that I can bring them to the attention of the Revision Committee.

Trying to get the best practices here.

I know eyewash stations are 5 minutes per week.

What is the frequency you use for testing showers and the duration?

Thanks in advance.
