Real-Time Assessment of Air Contaminants Using Video Exposure Monitoring Methods and Techniques

Occupational exposure assessment is one branch of exposure assessment and addresses the exposure problems that occur in the workplace. Through exposure assessment, we generally describe and identify the nature and size of the various populations exposed to hazards, the magnitude and duration of the exposures, and the causal factors of exposure. The present study explores the strategy for occupational video exposure monitoring includes video data in the assessment process and aims to establish an association between exposure levels and workplace events and to identify the causal factors. The case studies represent the progression in the development of real-time monitoring of exposure to different types of hazardous materials. Further the current application and development of each part of the assessment system and new ideas for improvement of the VEM system are suggested.
