ABSTRACT:
A safety shower adapted for reliable operation under all weather conditions is provided with strategically located bleed means for draining water from the shower, at least one of such bleed means including a temperature sensitive valve which permits limited flow of supply water upon the occurrence of predetermined ambient temperature conditions.
In temperature zones the temperature sensitive valve will be one responsive to near freezing temperatures, in equatorial zones the temperature sensitive valve will be one responsive to dangerously high water temperatures, and in intermediate and temperate zones both types of temperature sensitive valves may be employed.
Other bleed means is preferably employed to facilitate draining of water from portions of piping beyond the shower activating means when the shower is not in use.
