A Thermostatic Mixing Valve (TMV) that is used on eyewash stations and deluge showers blends hot and cold water together so that outlet temperatures are safe and prevent scalding from hot water. A thermostatic mixing valve (TMV) ensures that when an eyewash or shower is used, the injured person stays in position for the 15 minute time needed to flush or wash off the contaminant, chemical or particles that are causing damage to the eyes or body.
With the new ANSI 2009 standard, the requirement is now that the water used in emergency eyewashes and showers has to be between 60 and 100 degrees fahrenheit. A thermostatic mixing valve designed for eyewashes can be purchased separately and added to your current safety shower or eyewash and can be purchased as a package with your eyewash or shower.
