This report describes the process of performing a Helmet-CAM Respirable Dust Survey and the Enhanced Video Analysis of Dust Exposures (EVADE) software program, Version 1.0, that is designed for analyzing dust exposure in the mining environment at surface mines through the simultaneous use of video and real-time dust concentration data. The Helmet-CAM procedure, developed by researchers at the National Institute for Occupational Safety and Health (NIOSH) for personal sampling of respirable dust, is a technique that uses a video camera worn by the worker to provide a visual record of the worker's activities concurrently with data collected by a real-time datalogging aerosol monitor also worn by the worker. The EVADE software program merges the video file and dust concentration data file, allowing the user to use a computer to view them at the same time to identify potential dust exposure sources. This report defines the input file types and provides instructions for installing and operating the EVADE software. A step-by-step procedure is included to aid the user in conducting an analysis for identifying respirable dust exposure sources.
