About Tempered Water

In the morning before hopping into the shower, you may overestimate how low your body temperature is and turn the shower dial to the hottest that it will reach. You then step your entire body into the water and react to the scalding hot water by stepping away from the water, and turning the dial to a lower temperature. Unfortunately in an emergency situation, you are not given the chance to adjust the temperature of flowing water. Emergency eyewashes and emergency showers can be the solution to mitigating an injury while on the job. But if the equipment produces water that is either too hot or too cold and does not comply with ANSI Z358.1, the injury could possibly be made worse.

Water temperature should range from 60° to 100° F (15.5° C to 37.7° C) throughout the entire 15 minute drench or irrigation cycle. When showering at your home shower, the temperature should rest around 105° F (40.5° C). Room temperatures range around 68° F to 70° F (20 °C to 21.1°C), so it is important to consider victim comfort when running water temperature in an emergency shower or eyewash. If the temperature should fall around the lower range of the ANSI requirement, the victim may not feel comfortable through the duration of the cycle. A thermostatic mixing valve that regulates temperature spikes is fitting in making sure temperature stays controlled.

The victim is the number one priority in emergency situations, and you want the victim to abide by flush requirements in order to alleviate the injury. If the temperature is uncomfortable to the victim, the victim will feel pressure to leave the shower which may exacerbate the injury. We want the victim to feel comfortable, and once the victim does find comfort, he or she is more likely to remove contaminated clothing to boost the wash objective. Tempered water is a crucial factor to consider for victim comfort. Avoid legal repercussions and test your emergency shower and eyewash's temperature regularly!
