The course will prepare you to prepare an economic and financial study of a project to prevent accidents or occupational diseases. The course is made up of three modules divided into 19 classes. Module I addresses the concepts of financial mathematics as a preparatory way for module II. Module II addresses the elements and economic indicators for evaluating an investment project. Module III presents a case study, applying the concepts learned in modules I and II to evaluate an investment project in a factory, with the objective of reducing occupational noise and thus preventing hearing loss. With this knowledge you will be able to propose investment alternatives in accident prevention using economic indicators, which is the language understood by decision makers when allocating resources for investment. To consolidate the knowledge acquired in this course, you will need to practice. Therefore, upon completing the course, choose a problem in your company and apply the knowledge acquired to propose solutions and evaluate how viable the proposed investment is. One of the success factors of an economic analysis is collecting data and converting losses and gains into money. If this is not done with discretion and assertiveness, the result of your analysis may not be real. When concluding a proposed investment after an analysis, it is important to revisit the analysis and compare the predicted results with those that actually occurred. This is a way for you to continuously improve your skills.
