The objective of this research was to determine by means of a computational model the degree and area of affectation implied by the release of a toxic ammonia cloud from a 1000 Kg storage tank. The SCRI-Fire simulator of the company Dinámica was used. Heuristics feeding it with meteorological data from the city of Los Mochis, Sinaloa, physicochemical properties of ammonia and characteristics of the tank. The simulation was carried out in the summer and winter scenarios. As results of the simulation, in case of an ammonia leak, at a distance of 1038.67 meters there would be a concentration of 2500 ppm, which could produce the obstruction of the airways in people and at a distance of 818 meters there would be 5,500 ppm of ammonia, which is fatal to people for an exposure time of 30 minutes. Good management of dangerous substances such as ammonia is necessary, to avoid damage to the health of exposed people and negative effects to the environment, constant training of personnel who handle this dangerous substance is required, and that companies that handle ammonia are They are far from residential areas, and places with a lot of people.

Abstract: (spanish)
El objetivo de esta investigación fue determinar mediante la realización de un modelo computacional el grado y área de afectación que implica la liberación de una nube toxica de amoniaco de un tanque de almacenamiento de 1000 Kg. Se utilizó el simulador SCRI-Fuego de la empresa Dinámica Heurística alimentándolo con datos meteorológicos de la ciudad de Los Mochis, Sinaloa, propiedades fisicoquímicas del amoniaco y características del tanque. La simulación se realizó en los escenarios de verano e invierno. Como resultados de la simulación, en caso de una fuga de amoniaco, a una distancia de 1038.67 metros se tendría una concentración de 2500 ppm, lo cual pudiera producir la obstrucción de las vías aéreas en las personas y a una distancia de 818 metros se tendría 5,500 ppm de amoniaco, lo cual es fatal para las personas para un tiempo de exposición de 30 minutos. Es necesario un buen manejo de sustancias peligrosas como es el amoniaco, para evitar daños a la salud de las personas expuestas y efectos negativos al ambiente, se requiere la capacitación constante del personal que maneje ésta sustancia peligrosa, y que las empresas que manejen amoniaco se encuentren alejadas de zonas habitacionales, y lugares de mucha concurrencia de personas.
