Read full description

Know when and where workers were exposed to dangerous conditions and gain visibility into unsafe worker behaviors using iAssign® Technology and the Ventis® Pro Multi-Gas Monitor. iAssign® Beacons and iAssign® Tags make it easy to automatically track what’s happening on a worksite and interpret gas detection data without the need for wireless connectivity. iAssign Beacons automatically assign site names to Ventis Pro monitors based on proximity, helping safety managers to make sense of datalog information. Using Bluetooth technology, iAssign Beacons provide an added layer of safety and security by alerting users when they have entered restricted or dangerous areas. iAssign Tags allow workers to manually “tap in” and “tap out” of a location which allows anyone reviewing the data to easily see who had the instrument and where the operator was using it, making the information more actionable.
