Video Exposure Monitoring is a technique that allows the identification of specific tasks which contribute most to a worker's occupational exposure to hazardous agents. This technique, developed over the past 15 years, has undergone many changes. This presentation will discuss the current state-of-the-art methods and possible future directions for development of Video Exposure Monitoring. Video Exposure Monitoring uses direct reading instruments and video recordings to tie worker exposures to job activities, identifying activities that impact a worker's overall exposure. Changes in direct reading instrumentation over the years have made Video Exposure Monitoring easier, by providing more reliable monitors with many useful features, such as integrated data loggers. Video equipment has also dramatically improved, becoming smaller and easier to use, while improving image quality. A final product of this technique is a video recording combining the graphical representation of the worker's exposure with the job activities being performed. These video recordings can be used in training, demonstrating how activities can affect the worker's exposure. The hardware needed to overlay the exposure data is relatively inexpensive and simple to use. The software generating the graphical representation of the exposures was written specifically for this application. In addition, data collected through this technique can help predict the impact of a particular control, allowing safety and health professionals to prioritize control efforts to make the best use of scarce control resources. As technology changes, many aspects of Video Exposure Monitoring may be impacted. Direct reading instruments are continually improving, with smaller, more specific instruments becoming available. The move to digital video offers opportunities for improvements, allowing many of the video overlay functions to be carried out on a personal computer. As these changes progress, Video Exposure Monitoring should gain acceptance and be used by more occupational safety and health professionals practicing in non-research roles.
