“…A HazOp report may review all possible deviations, as well as their causes and consequences and proposes mitigation and active or passive protection (Labovský et al, 2007). According to Schüller et al (1997), the soundness of the methodology is a function of the extent of the known interactions evaluated and the detail level of the analysis, and the depth of study of the identified consequences.…”

“…A limitation of HazOp is that this approach is inherently qualitative (a "diagnostic tool") (Crawley et al, 2000). Moreover, there is the difficulty to estimate the time required for a complete HazOp study (Dunjó et al, 2010;Freeman and Mcnamara, 1992;Khan and Abbasi, 1997) as well as a lack of risk acceptability criteria and international standards, as discussed by Rouhiainen & Gunnerhed (2002) and Labovský et al (2007).…”

Explosives are widely used in extraction of ores, melts and fuels and in the safe and economical demolition of structures. These applications demonstrate the value of explosives to society and the reason why they are manufactured worldwide despite the hazard of their preparation. Hence, this paper focuses on the manufactory of the military explosive Hexogen (also known as RDX). The characteristics of the process are described by the analysis of a specify manufactory plant. The chosen analysis tool is the Hazard and Operability Study -HazOp. Historically, this methodology has been applied at chemical industries and is used in industrial process operability analysis. This study analyses seven critical nodes in the RDX manufacturing process, identifies several deviations, and causes and consequences. From these results, improvements in the units are suggested and actual conditions discussed. It is important to remark that this work is an initial approach to analysis of the manufacturing process of RDX using the HazOp methodology.

“…Lawley [8] defined and delineated the principles needed to carry out operability studies and hazard analysis due to the increasing complexity of new processes that could not be examined thoroughly using the then-conventional approaches based on equipment-oriented practices. Indeed, the requirement for having process-oriented methods [161][162][163][164][165][166] 3.6 of examination was the reason for the generation of HAZOP. Lawley's paper defines the planning, execution, and treatment of the operability study.…”

“…Is this decrease continuous at some rate? Answers to these questions may be obtained by an appropriate mathematical model (Švandová et al, 2005a;Švandová et al, 2005b;Labovský et al, 2007a;Labovský et al, 2007b). In such a model approach, the extent of the deviations may be easily incorporated and possible consequences can be investigated.…”
