Is the a need for safety shower water heaters to be feed from a secure source?

why would a safety shower need a water heater in the first place?

the worst thing that happens is the guy gets cold when he uses the shower. I am not seeing a safety issue here.

OSHA requires the water to be heated for most required showers but as far as I can tell searching the manual thy do not require emergency backup of the heating system. Other documents may and it could be dependent on the type of hazard being exposed to.

How do you keep the pipes from freezing?

I have never seen a safety shower with a water heater before and I have seen hundreds of them. Granted most were inside, so maybe the OSHA rule another poster claimed requires heated water for safety showers only applies to outside showers.

I don't think the actual OSHA rules require a specific water temperature, but there is an ANSI standard that requires "tepid" water and that standard is enforceable under the general duty clause.

I'm not sure about the temp. either, but I know there has to be enough tepid water for a long duration.

That always results in a very large tank, or an instantaneous heater.

That's not good. Inside or out, there is a requirement for a certain duration of tepid water. And the flow rate used for the calculation is always really high.
 
Yes its for outside showers, there are instant water.. I just need to be sure there it doesnt required to be feed from a secure source/emergency panel

What is tepid? Is it defined?

One safety magazine says this:

In 2009, the International Safety Equipment Association published the revised ANSI standard (Z358.1-2009) for emergency eyewash and shower equipment to incorporate a delivery of tepid potable water at a temperature range of between 60° F and 100° F. Although tepid water has been discussed for years, this was the first time it was placed in the ANSI standard. However, the wide range in temperature should be closely scrutinized by each employer. I doubt anyone would last 15 minutes in a shower that is running at 60° F. Even the upper range might be too uncomfortable depending on the type of exposure or injury. Narrowing the range down to between 80° F and 90° F might be more practical when determining the precise temperature range to consider
