Abstract

LOPEZ-MOLINA, Antioco; VAZQUEZ-ROMAN, Richart  and  DIAZ-OVALLE, Christian. Learning from the Accident in San Juan Ixhuatepec-Mexico. Inf. tecnol. [online]. 2012, vol.23, n.6, pp.121-128. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642012000600013.

The Dow fire and explosion index and the quantitative risk assessment methodology are applied to analyze one of the most unfortunate accidents in Mexican history: the explosion of gas storage tanks at the San Juan Ixhuatepec plant in Mexico. Additional calculations of over-pressure and thermal radiation are carried out to further explain the domino effect produced as a consequence of the accident. The results give evidence that facilities in San Juan Ixhuatepec had a moderate risk level which is in disagreement with people’s perception of the Pemex company, proprietary of the plant. This study concludes that the accident was mainly due to human error, as well as the inappropriate location of the plant.

Keywords : explosion; risk assessment; Dow fire and explosion index; overpressure.
