Explosives case study

The following case study illustrates the use of SCREEN. In this example we analyze a fire incident that occurred at a wood preserving facility. The incident involved a fire and explosion of six cylindrical vessels containing creosote and pentachlorophenol. Refer to Figure 15. [Pg.335]

In this section, three examples of blast calculations of BLEVEs and pressure vessel bursts will be given. The first example is designed to illustrate the use of all three methods described in Section 6.3.2. The second is a continuation of sample problem 9.1.5, the BLEVE of a tank truck. A variation in the calculation method is presented instead of determination of the blast parameters at a given distance from the explosion, the distance is calculated at which a given overpressure is reached. The third example is a case study of a BLEVE in San Juan Ixhuatepec (Mexico City). [Pg.292]

In this case study, one of the strongest blast-generating BLEVEs to occur in the Mexico City incident (Section 2.4.3, Pietersen 1985), will be investigated. This BLEVE occurred a few minutes after the initial vapor cloud explosion and probably involved two 1600-m spheres. The spheres were probably 50% full at the time of the accident. [Pg.308]

A CASE STUDY OF GAS EXPLOSIONS IN A PROCESS PLANT USING A THREE-DIMENSIONAL COMPUTER CODE... [Pg.363]

The present work will apply one of the above mentioned 3D codes, namely the EXSIM code, to a case study of gas explosions in a process plant. The scenario was specified by Mancini for use in a workshop at a recent conference arranged by the Center for Chemical Process Safety of the American Institute of Chemical Engineers (CCPS/AIChE 1991). [Pg.365]

The preceding case studies have shown that gas explosion calculations inside realistic process plant layouts are possible, using the state-of-the-art 3D computer model, named EXSIM. The peak pressures found in the four chosen calculation cases are summarized in the following table ... [Pg.380]

Finally, CCPS is grateful to Dr. B. H. Hjertager, Telemark Institute of Technology and Telemark Innovation Centre, Porsgrunn, Norway, for preparing A Case Study of Gas Explosions in a Process Plant Using a Three-dimensional Computer Code (Appendix F). [Pg.397]

Insights into the human causes of accidents for a specific category of process plant installations are provided by the Oil Insurance Association report on boiler safety (Oil Insurance Association, 1971). This report provides a large number of case studies of human errors that have given rise to boiler explosions. [Pg.23]

This case study concerns the events leading up to the hydrocarbon explosion which was the starting point for the Piper Alpha offshore disaster. It describes the investigation of the incident using the sequentially timed events plotting (STEP) technique. Based on the STEP work sheet developed, the critical events involved in the incident are identified and analyzed in order to identify their root causes. [Pg.293]

The case study has documented the investigation and root cause analysis process applied to the hydrocarbon explosion that initiated the Piper Alpha incident. The case study serves to illustrate the use of the STEP technique, which provides a clear graphical representation of the agents and events involved in the incident process. The case study also demonstrates the identification of the critical events in the sequence which significantly influenced the outcome of the incident. Finally the root causes of these critical events were determined. This allows the analyst to evaluate why they occurred and indicated areas to be addressed in developing effechve error reduchon strategies. [Pg.300]

To identify this set of final feasible solutions, X e 1, with low scores, we developed a greedy search procedure, S (Saraiva and Stephanopoulos, 1992c), that has resulted, within an acceptable computation time, in almost-optimal solutions for all the cases studied so far, while avoiding the combinatorial explosion with the number of (x, y) pairs of an exhaustive enumeration/evaluation of all feasible alternatives. The algorithm starts by partitioning the decision space into a number of isovolu-... [Pg.125]

A study investigated the effects of HMX in 24 male munitions workers who were also exposed to cyclotrimethylenetrinitramine or RDX. Although air levels of RDX were measured (0.28 mg/m ), levels of HMX were not. Compared with an unexposed control group of 237 men, there were no differences in various hematologic, renal, and hepatic indices. Another study in a group of 558 male and female munitions workers examined the immunologic effects of explosives. The study was prompted by the occurrence of three cases of lupus erythematosus at one munitions plant in 2 years. The workers were exposed to HMX and RDX, either alone or in combination... [Pg.383]
