Tempered Water for Safety Showers
Tempered Water for Safety Showers
(OP)
Does anyone have any experience with this? I have 10 - 14 PSIG steam and three showers to feed, two of which could be flowing. Everything I find is big, complicated and expensive. Looking for a simple, efficient solution.

Make sure you have the flows and heating capacity required. Safety showers should be able to be supplied with tepid (not tempered) water for up to 15 minutes.

Searching my saved files resulted in an add from www.enconsafety.com.
Searching standards, I am surprised to find no ASTM, NFPA or ASME standards for safety showers. Several DIN and European standards exist.

One has to look at the possible uses of said shower to determine any temperature adjustment. Most of our exposures one would want the coldest water possible. I know very few chemicals that I would want warm or tepid water. In hot area we have continuous water flow within the shower standpipe in very hot areas. We have electric heater on some external showers. These are built in heaters by the supplier.

The temperature is very important due to reactivity. Tepid water is defined as 60F-90F. So within that range, you should be able to find a good temperature. Most mixing valves for the safety systems are preset at 80F.
