Tepid Water Systems
A Tepid water system is used to supply clean warm water throughout a plant for safety showers and eye wash stations. Potable water is brought into the skid and stored in a stainless steel vessel equipped with a steam heat exchanger.
The water is continuously circulated throughout the plant using two centrifugal pumps and a UV sterilizer prevents the growth of bacterial in the water. The skids can be sized to accommodate most any demand.
Is your sites Emergency Eyewash and Shower Equipment in compliance with the latest ANSI Z358.1 standards?
Many sites are not complaint with the revised 2014 standard stating water temperature should be tepid and delivered at 60F to 100F to the emergency shower and eye wash equipment. In order to comply, it is necessary for sites to install updated equipment. This is where it makes sense to select a partner who can help design a system to meet your sites specific needs and take into consideration other codes such as NSF (National Sanitation Foundation), UPC (Uniform Plumbing Code) and IPC (International Plumbing Code) based on your local requirements.
Tepid water equipment
Tepid water equipment must be designed to delivery water at 20gpm for 15 minutes at each shower/eye wash station. Typical tepid water skids include a stainless tank, pumps, strainers, pressure relief valves, tank level and pressure switches, mixing valve, immersion heater, expansion tank, and control panel. Options can include freeze protection, UV treatment, steam heating options. Tanks and pumps are designed according to how many shower/eye wash stations are on a circuit and based on how many showers could be activated at the same time and include a study of the piping system length, elevations, and pressure drop for the circuit. Systems should be corrosion resistant with stainless steel being typical.
Having emergency shower and eyewash stations is not enough.
In addition to training on their use, per ANSI Z358.1-2014, emergency showers and eyewashes are to be activated weekly with a more thorough evaluation on an annual basis. With some sites having hundreds of shower and eyewash stations, many will use a third party service, but it can make sense to have multiple site personnel trained to do weekly checks so testing can be done quickly, make facility maps, and hold recurring training classes.
To ensure your site is in full compliance with various codes, standards, and best practices, make sure to select a partner who can go beyond just providing part of the puzzle.
