Managing jobsites with dozens or hundreds of workers can be a headache for site supervisors, and getting workers to report every small injury or safety incident is a challenge for safety managers. To meet this need, Triax Technologies, Norwalk, Conn., has launched Spot-R, a small, belt-mounted sensor that automates safety reporting on the jobsite.

A construction worker wears the discreet sensor unit on a belt clip, and a wireless system tracks their movements and logs their activity data, similar to popular fitness-tracking wearable devices. But the Spot-R is able to track more than jogging, using an accelerometer, gyroscope and altimeter to instantly recognize when and where a worker has fallen or stumbled.
