YOUR WORKERS STEP ON SITE. Safety risk reduction begins the second workers step on site and continues in real-time until they go home.  FIRST, CLOCK-IN. When workers arrive on-site, they take the AlertMeter test on company tablets or their own smartphones.  It takes 10 initial tests for the AlertMeter to recognize each user's normal level of alertness and individual cognitive behavior. After that, the test will accurately identify when they're outside their normal range of alertness.  THEN, GET NOTIFIED. The designated supervisor or manager on-site will be automatically notified if a worker is outside of his normal range of alertness, or is behaving unusually. FINALLY, REDUCE RISK. The designated supervisor or manager will meet with the worker face-to-face, discuss a way to remedy their alertness, and determine whether they will need to be reassigned to a non-safety sensitive task until their alertness level is normal.      ![Canva Design DAEKyjF-Pck](https://www.predictivesafety.com/hs-fs/hubfs/Canva%20images/Canva%20Design%20DAEKyjF-Pck.png?width=2000&height=1125&name=Canva%20Design%20DAEKyjF-Pck.png "Canva Design DAEKyjF-Pck") ### YOUR PLAN TO  REDUCE SAFETY RISK TODAY Getting the AlertMeter® Into Your Company Is as Easy as 1-2-3!
