This cheerful little advertising film purports to be an educational feature showing how to be a good do-bee and not a bad don't-bee while working in a mine. Remember, no smoking when underground because of all those nasty explosive gasses you know. However the sub text always seems to be -look how attentive to the safety of the miners the mine management is. For Kieslowki's part he seems to be interested in the way things are done - the nuts and bolts of just who the thing is done, in this case the actual mining of copper. Implicitly however there is the feeling that all of this is for show, and probably the mine, like every other state business enterprise in Poland, and every other mine in the world, is operated with the first priority to cost effectiveness and productivity, with actual worker's safety well down the list, letting chance, whatever the rules might say, dictate the actual survivability of the work. Whatever, this must have been satisfactory to the mine's managers as they gave him another project.
