Prevent Heat Stress Before It Starts: MX3 Hydration Testing

Heat stress doesn't show up all at once — it starts small, with fatigue, dehydration, or dizziness, and turns serious fast if it's not caught early. That's why NAFECO partners with MX3 Diagnostics to bring real-time, field-ready hydration testing to your job site. Using a simple saliva-based test, MX3 delivers instant, objective hydration readings in seconds, so you know who's ready to work before they clock in — not after symptoms appear. The technology has been tested by the U.S. Air Force against $25,000 lab equipment and found to be highly accurate, and it's trusted by major industrial contractors, professional sports teams, and every branch of the U.S. military.

Beyond individual testing, the MX3 portal lets you track and analyze hydration trends across your entire workforce at no extra cost, giving supervisors real-time visibility to spot patterns, change behavior, and make data-driven safety decisions. Companies like Brown and Root and Clean Harbors have used MX3 to go entire seasons without a reported heat-related incident, and the data trail also supports compliance with OSHA's National Emphasis Program on heat illness prevention.

As a family-owned safety partner, NAFECO is proud to bring proven tools like MX3 to the people who protect our communities every day. Contact your NAFECO rep to learn how MX3 hydration testing can help keep your team safe this season.
