Video technology has been utilized for the production of training films focusing on occupational hygiene topics for at least two decades. These films have mainly been produced in a traditional way with some basic story told, illustrated with video pictures and accompanied by a speaker voice. The introduction video exposure monitoring technologies as PIMEX have made it possible to develop the use of video by adding additional information to the video picture about, at the same time occurring exposure to e.g. air contaminants. This technology has meant an important advance what concerns improved understanding of the link between occupational exposure and the situation in the work place and worker behaviour. The improved possibility to involve the worker and supervisors in the search for effective control measures is perhaps the most important characteristic. This technology is now used in several countries and the experiences from its use prompts for continued development and widened use. The development of video technology, especially digital video and the possibilities to do professional editing in standard computers implies a fantastic possibility and challenge for the occupational hygienist. Digital video cameras, computers with video editing as standard and possibilities to produce ready products on built in CD or DVD burners are now common products on the consumer market which implies that the price level has gone down drastically. With those tools is it therefore possible now to produce advanced reports and especially effective, visualized training materials. This way of using the technology is already in use in different countries for production of exposure study reports as CD-ROMs including text as well as video illustrations. At the Swedish Institute for Working Life has training videos using visualization methods as PIMEX been produced for many years. In recent year has this production been developed in many ways to make a wider and more effective distribution of knowledge possible? One example is the production of an extensive training material focusing on control of occupational exposure to dust. This product is also produced in html-code, which means that it can be used in most standard computers and that it is prepared for distribution on Internet. The duplication of such a product is not expensive and the possibility to distribute via Internet makes a wide knowledge spread possible. Other examples have focused on hazard control in wood industry and the organisation of a systematic work environment management system. The today available technology based on digital video and computer technology has made it possible for non-professional video producers to produce and distribute training material which are much more effective to get the message across. This possibility may be compared to the introduction of word processing technology which today makes it possible for any hygienist to write professionally looking reports. It is now time for occupational hygienists to utilize the new possibilities for production of effective training tools.
