Ammonia is a toxic compound and has many toxic effects on humans and the environment. This study was designed to model the consequences of ammonia leakage in an industrial slaughterhouse. Given the potential hazard of ammonia, only the toxic dimension of this gas was evaluated. The scenarios were evaluated in the worst possible condition and in the case of the complete rupture. Findings showed that in case of a catastrophic rupture scenario in reservoir 1 in the first and second 6 months of the year, the distances of 920.37 and 569.38 m from the reservoir in the wind direction were at Emergency Response Planning Guidelines, level 3 (ERPG3), respectively. In reservoir 2, in the first and second 6 months of the year, the distances of 699.58 and 384.86 m from the reservoir were at the ERPG3 level, respectively. In reservoir 3, in the first and second 6 months of the year, the distances of 203.48 and 748.28 m from the reservoir were at the ERPG3 level, respectively. Examination of the probit values showed that in reservoirs 1 and 2, the probit values were more than 4.28 up to 100 m from the reservoirs, and in the reservoir 3, the mortality rates were lower. The findings revealed that the catastrophic rupture of ammonia reservoirs in the studied slaughterhouse and the release of ammonia could lead to the fatality of large numbers of people in ERPG2 and ERPG3 areas. Therefore, it is necessary to take control measures to reduce the vulnerability against such accidents.

“…A complete list can be found on the Support Center for Regulatory Air Models, US EPA (2012e). The type of model appropriate for a particular use depends on the scale of the problem, on the level of detail of the information available as input to the model, on the level of description desired for the model output and on the waiting time available to finish the model computations (Beychok, 1994;Dandrieux et al, 2006;Doury, 1988).…”

“…Although much work [3][4][5][6][7][8][9][10][11][12][13][14][15] for hazardous dust and gases was conducted, the study of dedusting effects in confined workplace using finite volume method was seldom used. In this paper, the concentration of dust flow, which mixes with SiO 2 and air, is calculated using three different dedusting methods.…”

This paper aims to the study of dedusting effects in confined workplace using finite volume method. First, the diffusion phenomenon of dust flow is described by discrete phase model, and the numerical results are compared with the experimental data. Second, the concentration of dust flow, which mixes with SiO2 and air, is calculated by three different dedusting methods, such as the exhaust fan method, the window ventilation method and the humidifying spray method. In terms of comparison results, the exhaust fan method has the best dust removal effect in confined workplace, and the humidifying spray method has the worst effect. The paper provides a technical support for dedusting design of confined workplace in the occupational hazards prevention field.
