Real-time personal monitoring in the workplace using radio telemetry.
NIOSH 1991 Feb; :473-481
The usefulness of radio telemetry for field surveys was investigated at a furniture stripping operation. Using radio transmitters and a base receiver, exposure data from a direct reading instrument can be displayed and stored at a personal computer. More than one worker at a time can be monitored using a multichannel receiver, and multiple exposure curves can be displayed on the computer screen. The system offered advantages over other methods of data collection. Using telemetry, workers under study can enjoy more natural movement than they can by being tied with coaxial cables. Unlike data loggers, radio signals produce instantaneous results. In the case reported here, the worker carried a radio transmitter that was attached to a photoionization air analyzer. Qualitative methylene- chloride (75092) exposures were remotely monitored on a video monitor throughout the day. Increases in exposure levels, due to job tasks, work practices, and emission sources were immediately identified so that corrective action could be taken at that time.
