Video filming and pollution measurement as a teaching aid in reducing exposure to airborne pollutants.
A method called PIMEX has been developed for investigation of the causes of exposure to airborne pollutants at workplaces. The method involves measurement of the subject's exposure with a personal, direct-reading instrument. The sampling signal is transmitted by telemetry to a special video mixer. A video camera is also connected to the video mixer. The camera is used for filming the subject. The video mixer's output signal is fed to a monitor which continuously shows how the subject works and how exposure varies. The method has been used for producing two films on the causes of exposure to solvent and effective measures for reducing exposure: one deals with screen printing and the other with surface treatment at wood-processing plants. The films have been shown at a large number of workplaces at discussions about workplace conditions, proving useful tools in efforts to reduce workplace risks and giving rise to concrete measures and increased interest in the workplace environment.
