The need for industrial hygiene practitioners in developing countries is immense, and the global industrial hygiene community is now at a crossroads: either seize the opportunity and grow, or maintain the status quo and wither away through attrition and competition. For growth, we must stimulate more occupational hygiene education/training efforts, especially in developing countries, in addition to developing and maintaining intermediate-level and professional-level certification programs. This session will discuss the needs, opportunities and models for the implementation of training and certification programs that can be recognized by all IOHA occupational hygiene associations and certifying bodies. The goal is to facilitate growth of occupational hygiene practice around the world, especially in developing countries that have no professional bodies or degreed occupational hygiene programs, while ensuring quality and consistency in knowledge and skills among these practitioners. Perspectives from several large corporations that have implemented programs internally will be shared.
