Monitoring exposure to solvent vapour in the workplace using a video-visualization technique
2002
A video-visualization technique, using a combination of a fast-response, direct-reading, personal gas monitor (photo-ionization detector) and synchronized video monitoring (with a standard camcorder), has been applied to assess exposure to solvents in various industries. The objective is to understand how short-term peaks occur and how they can be controlled to minimise both short-term exposure and their contribution to long-term exposure. The technique was employed to identify peaks associated with work activities and their contribution to total exposure arising from use of tetrachloroethene in a dry cleaning establishment. The exposure and video data are simultaneously displayed on computer and the information is disseminated on CD (and video), forming the basis of a detailed occupational hygiene assessment or training material.
