Subject: More Safety Eyewash and Shower Question

How are people dealing with the tepid water requirement of ANSI Z358.1?

Looking on the Web, it looks like its not really being honored.

The temperature range for 'tepid" is defined in Section B6 of 
Appendix B as being from 60 to 100 degrees F.

So some more questions:
*  How do people who have tepid water units verify temperatures? By 
feel? By measurement? If measurements are used, please describe the 
procedure used.

*  Let's say the shower is indoors. Does someone have an idea of how 
long the tepid water lasts before the temperature drops to water main 
or ground temperature?

*  Let's say the shower is outdoors. Are there ways of avoiding water 
temperature extremes without a tepid water unit? Pipe insulation? 
More deeply buried supply lines?

*  Finally, tepid water units are mechanical devices with potential 
reliability issues of their own. Are they reliable? What sort of 
inspection and maintenance procedures do people have for them?

"Inquiring minds want to know."
