After several incidents or accidents, the most serious case being the one who struck the complex Skikda liquefied natural gas (GL1 / K) on January 19, 2004, the group Sonatrach sensitive to the incident has taken further steps along the lines of prevention safe knowing that the business risk is an integral part of the business industry and it is about health, safety, and environmental protection. These factors will be taken into account in the process of management and decision making at all levels. This study tries to find the causal factors of the explosion of 19 January 2004 (GL1 / K) and to develop a fault tree and assess the risks arising from these factors, why our research is based on interviews: at first, with an industrial safety engineer (Health, Safety, and Environment (HSE) Department, General Direction of Sonatrach), an executive director of insurance, a department head of insurance, an insurance consultant, a department head of downstream activity and two financial executives; secondly, a poll at the general direction with insurance adjusters and engineers in industrial safety; and finally a report may visit the complex which has been made (the report) 15 days before the explosion. The cause-effect diagram is used which is a cause-effect method both upwards (search for causes of failure) and down (search for consequences of failure) that can not only identify risks system and the detailed analysis, but also can describe the form of a single graph, both the normal operation of a system. The default trees developed show that all the risks assessed are located in areas: acceptable, undesirable, and intolerable, which requires the development of an action plan providing control measures at all sensitive points.
