BLT and Safety
Our tests for human performance are vital tools for ensuring safety in dangerous workplace environments. Used with good shift management and scheduling the BLT test provides another level of protection against fatigue and human impairment.

We have entered the smart phone/tablet world with an application that runs on both the iOS and Android platforms. Please see: Alertometer.

The tests are graphic, non-linguistic exercises designed to be enjoyable. They have been rigorously researched in clinical and field trials.

All BLT systems are patented. Research is funded by the CDC through National Institute for Occupational Safety and Health (NIOSH) and the National Institutes of Health (NIH).
