On the substitution for carcinogens in the working environment

The ultimate solution in prevention of occupational cancer risks would be to remove carcinogens from the working environment. Elimination of carcinogenic substances can be achieved by replacement of the carcinogen with non-carcinogen(s) having the same functionality, or by using a different process that produces adequate results without the use of carcinogenic agents. This paper presents selected methods and tools, which have been used for substitution purposes in practice. These are: 1. a strategy for substitution, 2. a tool for creating ideas on how to substitute, 3. a software package, SUBTEC, for solving some technical and industrial hygiene problems, and 4. a proposal for a strategy to deal with organizational and psychological barriers encountered when changes are to be introduced.
