  • Methods and data sources for identifying members of a regulated community
    • Authors: William C. Pittman; Zhe Han, Brian Z. Harding, Jiaojun Jiang, Camilo Rosas, Alba Pineda, M. Sam Mannan
      Abstract: The Ammonium Nitrate explosion that shook West, Texas in April 2013 revealed deficiencies in the current regulatory enforcement system used for chemical safety and security in the United States. This cannot be said to be a failure of existing regulations. Rather, it is a failure in enforcement as federal regulators either had not inspected the site in decades—as with OSHA—or had not been aware of its existence at all, as with Department of Homeland Security (DHS). Regulations cannot be effective if they are not enforced and cannot be enforced unless the regulator knows who the members of the regulated community are. Methods for identifying the regulated community and moving past the voluntary reporting and compliance system currently in place have become topics of acute interest and paramount importance. This article discusses existing data sources at federal, state, and local levels that could be exploited immediately to help DHS and other regulators identify regulated facilities and begin more concerted outreach programs. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • Dow learnings and actions from the deepwater horizon accident
    • Authors: John Champion; Kenan Stevick, Karen Study, Sheila Van Geffen
      Abstract: The Deepwater Horizon drilling rig explosion on April 20, 2010, killed 11 workers, injured 16 others, and resulted in an offshore oil spill in the Gulf of Mexico that is considered the largest accidental marine oil spill in the history of the petroleum industry. As with all major incidents in industry, there are lessons to learn from systemic failures that resulted in the tragic loss of life, insult to the environment, and the equipment loss. Many companies, including The Dow Chemical Company, followed the subsequent investigation closely to determine which lessons could be leveraged to strengthen internal programs. Risk identification and management systems in Dow's Process and Occupational Safety programs are robust. Dow management systems are intended to meet or exceed Industry Standards with respect to design, operation, and layers of protection. The prevention of large scale accidents like Deepwater Horizon depends on an acute awareness of worst‐case scenarios and an unfailing vigilance to ensure that essential protection layers are not compromised. Dow management system reviews in 2011 on the same management systems involved in this incident identified opportunities for improvement and/or action plans in several areas. This article will focus on three programs that resulted from those management system reviews. The three programs are: a targeted High‐Consequence Emergency Response Drill program, a High Potential Process Safety Near Miss Program, and technology‐specific Process Safety Cardinal Rules. For each of the three programs, a description of the content of the program and how it was implemented at the company level is provided. Specific examples of how these programs were implemented at a facility level are included. Each of these programs play a key role in preventing a catastrophic event and have been a part of Dow's continuing process safety performance improvement over the last several years. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • Probabilistic modeling of business interruption and reputational losses
           for process facilities
    • Authors: Seyed Javad Hashemi; Salim Ahmed, Faisal Khan
      Abstract: This article presents probabilistic models to estimate business losses due to abnormal situations in process facilities. The main elements of business loss are identified as business interruption loss and reputational loss. The business interruption insurance approach is used to model business interruption loss. The subelements of business interruption loss are modeled based on expert knowledge using Program Evaluation Review Technique, which are then integrated using the Monte Carlo simulation approach. The reputational loss is considered as Weibull distributed, and the parameters are estimated by applying a scenario‐based approach. Copula functions are then used to develop the distribution of the aggregate loss, considering the correlation between business interruption and reputational losses. The application of the loss models is demonstrated using a distillation column case study. The models presented here provide a mechanism to monitor process facility's business performance, with associated uncertainties, and to make swift operational and safety decisions. This will help to improve process facilities safety performance and optimal allocation of resources where they are needed the most. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • A method for barrier‐based incident investigation
    • Authors: Robin Pitblado; Tony Potts, Mark Fisher, Stuart Greenfield
      Abstract: Incident investigation is a formal requirement for high hazard facilities with the aim to learn from each incident and to prevent future recurrences. There are many published investigation methods, with most driving to the management system root cause and some applying newer barrier‐based methods. However, these methods either do not link tightly to the facility risk assessment or are very difficult to apply, and lessons from incidents that might reveal weaknesses, especially relating to major accidents, can be missed. This article describes a novel method for incident investigation (Barrier‐based Systematic Cause Analysis Technique) that combines the ideas of barrier‐based risk assessment with a well‐established systems‐based root cause analysis method (Systematic Cause Analysis Technique). The method described is efficient and can be applied by properly trained supervisors, and this potentially allows every incident or near‐miss event to be assessed in a consistent risk‐based format. The method clearly establishes links back to the facility risk assessment and thus identifies risk pathways that are potentially too optimistic (i.e., the risk is higher than predicted), and this can be due to initial optimism or degradation of safety barriers (human or hardware). © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • Using alarms as a layer of protection
    • Authors: Todd Stauffer; Peter Clarke
      Abstract: Alarms and operator response to them are one of the first layers of protection used in preventing a plant upset from escalating to an incident. This article discusses how to evaluate the risk reduction (or the probability of failure on demand) of this layer when it is considered as part of a layer of protection analysis. It examines key factors such as time to respond, operator training, human factors, alarm system performance, and the reliability of the hardware used to annunciate the alarm. Recommendations will be drawn from the ISA‐18.2 standard “Management of Alarm Systems for the Process Industries.” Analogy will be drawn with techniques used to analyze safety instrumented functions. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • Suppression effect of explosion in linked spherical vessels and pipelines
           impacted by wire‐mesh structure
    • Authors: Shangfeng Zhang; Zhirong Wang, Qingqing Zuo, Juncheng Jiang, Changde Cheng
      Abstract: A series of experiments are conducted to study suppression effect of multilayer wire‐mesh structure on methane‐air mixture explosion in linked vessels. Explosion suppression effect is analyzed for explosion suppression structures with different layers and meshes. The most reasonable multilayer wire‐mesh structure is obtained. The multilayer wire‐mesh has a greater impact on explosion intensity in the big vessel than that in the small vessel. The combination of different layer number and mesh number has different explosion suppression effect on explosion. Mesh number has little effect on explosion pressure in both vessels when the layers are few. When the layers are more, the explosion pressure in both vessels is greatly impacted by mesh number. Under the condition of the same mesh number, the more the layers are, the better the explosion suppression effect. 5 and 7 are the critical explosion suppression layer number for 40‐mesh and 60‐mesh wire‐mesh structure, respectively. Compared with 5‐layer 40‐mesh wire‐mesh structure, the effect of 7‐layer 60‐mesh wire‐mesh structure on explosion suppression is better. So, in actual explosion protection design, the optional explosion suppression structure should be decided by taking into account of the comprehensive effect of layer number and mesh number. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • A call to action—next steps for vision 20/20
    • Authors: Jack McCavit; Scott Berger, Cheryl Grounds, Louisa Nara
      Abstract: Process safety protects and enhances our individual health, our company's success, and our region's business economy. Companies that handle toxic, flammable, and explosive materials understand the importance of process safety and risk management. So do regulators. So should the community and other stakeholders. Individually, these stakeholders have been working for years to improve process safety performance. Accidents continue to occur. It is time to leverage our resources, knowledge, and skills to all strive for a common goal of great process safety performance. CCPS's Vision 20/20 describes that vision, which calls for effort from individual companies and effort that goes well beyond any individual company, indeed beyond the industries. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • CFD‐based simulation study on producer gas explosion in an
           electrostatic precipitation
    • Authors: Kai Yang; Qiang Li, Zhijiang Ding, Lichun Xiao
      Abstract: Gas explosion is one of the most serious problems in the operation of electrostatic precipitation (ESP) which is applied to purify producer gas. Simulation study on the producer gas explosion in ESP has been conducted with computational fluid dynamic method. Producer gas explosion was studied experimentally in a closed rectangular vessel to validate simulation results. Numerical results were proved to be reliable and reasonable which could meet the engineering needs. The factors of flame propagation and pressure variation have also been analyzed. Furthermore, the effects of those explosion parameters such as premixed oxygen concentration, operating conditions, and local gas clouds with high oxygen content were discussed. The results show that maximum explosion pressure rises sharply with the premixed oxygen concentration increasing. Meanwhile, maximum explosion pressure increases with the operating pressure boosting, but decreases while the operating temperature elevates. Explosion pressure of local gas cloud with high oxygen content is a linear function of its volume. For this model, the critical diameter of gas clouds is 1.2 m with the oxygen concentration of 20%. The volumetric ratio of gas clouds in this model is 0.04. This study gives a reference for the optimization of oxygen monitoring‐feedback system response, and can provide theoretical guidance for the design of explosion protection. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • Lessons for effective integrity management from the San Bruno pipeline
    • Authors: Jan Hayes
      Abstract: In September 2010, eight members of the public were killed when a gas transmission pipeline ruptured at San Bruno, California. This article describes the causes of this serious organizational failure with a view to learning by other organizations that operate hazardous facilities. The rupture occurred when a longitudinal seam weld failed. The weld had been poorly made at the time the pipeline was fabricated and installed in 1956. The line had not been inspected or tested since that time. While the details are specific to the case at hand, organizational lessons are valid for other organizations operating complex sociotechnical systems that face the problem of sleeping or latent faults that can remain dormant for many years. This analysis focuses on the organizational arrangements that led to such ineffective integrity management, in particular how the potential for an event such as the one that occurred was systematically ignored by the operating company for many years. The key to effective management of the potential for disaster is to ensure that risk management does not become a “fantasy” but remains grounded in the reality of the dangers that the assets pose to workers, the public, and to the organization itself. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • Maintenance of fire sprinkler systems based on the dynamic assessment of
           its condition
    • Authors: José Sobral; Luis Ferreira
      Abstract: Safety is one of the major concerns of process safety engineers in most industrial facilities all over the world. To this scope, some events play an important role once the effect of their consequences can be assumed as totally undesirable. One of these events refers to the occurrence of a fire. Such event can result in catastrophic consequences for life, equipment, and continuity of activities or even leading to environmental damage. A fire protection equipment with low reliability means that this equipment are often unavailable and thus the risk of a fire increases. Maintenance of fire protection equipment is very important because this kind of systems is mostly in a dormant mode, which gives uncertainty about their operability when demanded in a real situation of fire. This article outlines the importance of tests, inspection, and maintenance operations in the context of a fire sprinkler system and proposes a methodology based on international standards and supported by test/inspection reports to correct the frequency of these actions according to the level of degradation of the components and regarding safety purposes. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • Analysis of a blast due to inadvertant mixing of ammonium sulfate and
           sodium hyplochlorite
    • Authors: Graeme W. Norval
      Abstract: Ammonium sulfate and sodium hypochlorite are common industrial chemicals, often used together in water treatment. The consequences of mixing hypochlorite (chlorine) solution with ammonia solutions are well understood within the chlorine industry; detonable chloramines are produced. This knowledge is not well known in other industries; fortunately, few locations have both chemicals on site. These products were inadvertently mixed, resulting in an explosion, at a water treatment facility in Kitchener, Ontario on April 2, 2014. The chemistry of the incident is presented and discussed. Facilities that handle both chemicals, such as the water treatment industry need to have heightened sense of understanding of this particular reactive chemical hazard. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • ASTM E2931: A new standard for the limiting oxygen concentration of
           combustible dusts
    • Authors: Ashok Ghose Dastidar
      Abstract: The National Fire Protection Agency (NFPA) has a standard on explosion protection systems, NFPA 69, which provides guidelines on effective inerting to prevent explosions. The standard specifies that for inerting to be effective the oxygen concentration must be kept below the Limiting Oxygen Concentration (LOC). It then goes on to specify that the ASTM International standard E2079 be used to establish the LOC. The shortcoming of this approach is that ASTM E2079 only applies to combustible gases and vapors and not combustible dusts. As a result of this deficiency ASTM International has just introduced a new standard, ASTM E2931, Standard Test Method for Limiting Oxygen (Oxidant) Concentration of Combustible Dust Clouds. This paper discusses the nuances of this standard and compares experimental results between the 20‐L chamber and the 1‐m3 chamber. Differences in the test results between the vessels and between test methods may have safety ramifications to the end user of the data. The large variation present in the repeatability and reproducibility of the LOC means that the current common practice of using a 2% safety margin for particle inerting (the least stringent of the inerting methods) may be insufficient to ensure dust cloud explosion mitigation. It is possible that additional study and improved laboratory proficiency as the test standard matures will bring down these repeatability and reproducibility errors. Additionally, if LOCs are reported in Safety Data Sheets without accompanying information regarding the test method or test vessel size used, the mitigation strategy may not provide adequate protection. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • Process safety in the classroom: The current state of chemical engineering
           programs at US universities
    • Authors: Sean J. Dee; Brenton L. Cox, Russell A. Ogle
      Abstract: The role of process safety in the undergraduate and graduate curriculum is a critical component of preparing chemical engineers for their future careers. In 2011, the Accreditation Board for Engineering and Technology (ABET) amended the requirements for Chemical, Biochemical, Biomolecular, and similarly named Engineering Programs. The change added a clause, indicating that the curriculum of said programs should not only include the engineering application of chemistry, physics, and/or biology to the design, analysis and control of processes, but also the hazards associated with those processes. Departments were then compelled to adjust their curricula to meet the new requirement which would go into effect during the 2012–2013 Accreditation evaluations. Herein, we present findings related to the major milestones and challenges associated with updating the chemical engineering curriculum to include process safety components at both the undergraduate and graduate level. First, a survey of publicly available information regarding curriculum requirements, course syllabi, and program developments at US universities will be discussed. Next, insights from evaluating the challenges associated with adding new content to an already overloaded curriculum will be discussed. Lastly, recommendations for continued improvement in the process safety education provided to undergraduate and graduate students will be presented. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • Infiltration hazards for building siting studies
    • Authors: Jeffrey D. Marx; Benjamin R. Ishii
      Abstract: Facility siting studies have been a requirement for many years, specifically for facilities that must comply with OSHA's PSM program. Facility siting is frequently interpreted as performing a building siting study which adheres to the guidance given in API RP 752. Many of the siting studies conducted for large facilities over the past few decades have focused on explosion overpressure impacts to occupied buildings, with more simplistic evaluations for fire and toxic gas impacts. Toxic gas impact analyses often only evaluate the potential exposure of a building location, to a specific gas concentration, and do not evaluate the level of infiltration into the building where occupants may be impacted. Infiltration of flammable gases has largely been ignored in most building siting studies. Despite this oversight, this hazard is one which should be addressed when following the guidance found within API RP 752. Through the use of dispersion modeling and infiltration analyses, the hazards associated with flammable or toxic gas infiltration can be incorporated into a building siting study. This article outlines the process of conducting a building siting study in accordance with API RP 752, with specific emphasis on the consequence analysis for infiltration analyses. © 2015 American Institute of Chemical Engineers Process Saf Prog, 2015

  • Safety improvements in a Methanation reactor
    • Authors: Mike Walton; Tony Southerton, Paul Sharp
      Abstract: A 35‐year‐old Methanator vessel required replacement due to High Temperature Hydrogen Attack (HTHA). The opportunity was taken to upgrade the over temperature protection system to meet the requirements of IEC 61511. An additional Layer of Protection was added to reduce demand on the High Temperature Trip system. © 2009 American Institute of Chemical Engineers Process Saf Prog 2009
