Since the 1980s, video exposure monitoring (VEM)-a method that combines video monitoring with datalogging environmental instruments-has been used to evaluate exposures for workers during job activities that are performed in relatively fixed locations. Over the years, advances in video recorders, video file formats, exposure monitors, and software have increased VEM's viability as a monitoring method. However, one aspect of VEM has not changed: the restriction of its application to fixed work locations. The challenge of monitoring mobile workers-workers who do not have a fixed work location such as a plant or mill, or who do not work inside a cab with an effective air-cleaning system-persists.
