We will be having a meeting of the ISEA (International Safety Equipment 
Association) group on emergency eyewashes and showers next week in the 
DC area.  Some of these temperature issues will likely come up.  What 
advice to the DCHAS members have for me as member of this focus group?

This draft ANSI standard will refer not to industrial fixed-facility 
eyewashes/quick-drench showers but rather to those used either 
in/outside a hospital or in a HAZMAT/Toxic Terrorism scenario in the 

I can use any and all input.

There are supposed to be further meetings about eyewashes/showers in the 
industrial settings.  I can use any and all input into this as well.

  We have mixing valves on our most recently installed drench hoses and 
  eyewashes; I have not checked the actual temp, but it feels pleasant.  
  However, I have run into a problem with  the mixing valves-on my 
  monthly checks I found some with low flow rates which I reported to 
  maintenance. The person who fixed that said the mixing valves are 
  to clogging, partly from lack of use, and need to be checked weekly, 
  allowing them to run for several minutes.  Of course, that is still 
  preferable to having an injured person refuse to rinse as long as 
  necessary because of the ice cold water.

  I'm not sure about safety showers and will check ASAP.
