The AreaRAE provides real-time measurements and optional alarm signals when exposure exceeds preset limits. The portable multi-gas monitor contains up to five sensors that monitors total VOC via PID, carbon monoxide/oxygen/ammonia via electrochemical sensor, and lower explosive limit (LEL) via catalytic bead sensor. The AreaRAE is currently used at Hanford to provide chemical vapor monitoring to work teams. It will be used to support the Pilot-Scale testing in the same capacity, but with addition of wireless real-time data availability to TFMCS and SAFER Systems. The technical details of the AreaRAE are available here:
In the pilot scale demonstration, the AreaRAE DRIs are placed in the general tank farm areas to track transport from known PBF releases in the breathing zone and any evidence of fugitive emissions.
