PIMEX
PIMEX is one of the so-called video exposure monitoring methods which are used in occupational hygiene practise since their introduction in the mid-1980s. The name PIMEX is an acronym from the words PIcture Mix EXposure, and implies that the method is based on mixing pictures, in this case from a video camera, with data on a worker’s exposure to some agent. The main idea of the method is to make invisible hazards in the work environment visible and in this manner facilitate the reduction of hazards in workplaces.
