The Use of Real-time Monitoring to Characterize Temporal and Spatial Activity-Exposure Relationships

This technique involves simultaneous collection of real-time exposure data from direct-reading instruments and video recording of worker activities, then combines exposure graphics with the activity video to provide a composite video illustrating exposure as a function of worker location and activity. The composite video shows which activities contribute to exposure, and the exposure data show the relative importance of each activity to overall exposure. Activities can then be ranked in order of importance and prioritized in terms of control needs. This technology can be used to evaluate and compare the efficacy of different control strategies. The information derived from this method also has potential use as a worker training tool.
