Individual health exposure at the workplace is measured by three factors: the amount of the emission type, the duration of the emission exposure and whether occupational safety and health equipment is worn.These factors are determined by „preVent“.

The system consists of sensor devices that measure emissions, transponders that detect entry and exit into the hazardous area, and sensors on the protective equipment that detect whether it is being worn. These individual data are safely collected on a server, synchronously combined and interpreted for the user only.
