Abstract: Accidents with leaks of industrial toxic gases such as hydrogen sulfide, a chemical agent found in oil refineries, are increasingly a concern of enforcement agencies. Accidents with hydrogen sulfide leaks can expose workers and the community to direct contact with the agent, leading to mild respiratory irritation and even death. Thus, the responsibility on the part of the companies with the handling of the same is the guideline of several studies to avoid accidents. Using as a method, simulations to evaluate and qualify possible risks of leakage in refinery installations. The study resulted in the classification of scenario simulations regarding the hazard it offers and the consequence analysis with gas cloud modeling performed by the ALOHA 5.4.4® software. These data were also treated in STATISTICA 8.0 software with a focus on predictions using determinant variables at the time of the leak.
