Tepid water made easier with new Speakman Safe-T-Zone® thermostatic mixing valves
Every day, about 2,000 employees experience an eye injury that requires medical attention, according to the Centers for Disease Control (CDC). In an emergency, water temperature matters. When not delivered at an appropriate temperature, water can cause severe damage. In the event of chemical exposure, water that is too hot or too cold can even intensify injuries. Speakman’s all new Safe-T-Zone® thermostatic mixing valves (TMVs) are engineered to regulate water temperature whenever an eyewash or emergency shower is activated, making tepid water easily available, resulting in equipment that performs to all required industry safety standards.
Speakman’s Safe-T-Zone® TMVs include high quality materials and improved performance. All Speakman Safe-T-Zone TMVs feature solid brass, lead free construction and are available in high capacity STW-350 (62.5 GPM), medium capacity STW-362 (38 GPM) and low capacity STW-370 (9.7 GPM) options. The new Speakman Safe-T-Zone® TMVs are available with optional accessories that include stainless steel flush or surface-mount cabinets for corrosion resistance with integrated locks and mounting brackets. Additional features include:
- Solid brass construction
- Lead-free bodies
- Installation flexibility with top or bottom inlet positioning depending on water supply location
- Adjustable set point to allow customization with water temperature

Tepid water tips
- ANSI/ISEAZ358.1 requires emergency eyewashes and showers deliver sprays that are tepid in temperature
- Tepid water is defined as between 60˚F and 100˚F
- Too cold - sprays below 60˚F can cause hypothermic shock
- Too hot - sprays above 100˚F can increase chemical reactions
- Tepid water is more comfortable and therefore more likely to be used properly to minimize the damage inflicted by harmful contaminants
- Tepid water helps the user keep the chemical burn or exposed area in the water stream for the recommended 15-minute flushing period.
