Processing industries safety risk

In this sub-Section a concise overview will be presented of safety indicators commonly used in current chemical process industry. Safety Indicators in this Chapter are restricted to the safety related risk indicators present in an organization. The Sis defined here are present in the chemical process industry in the form of operational data, and in the form of results from (safety) tools. In both cases the Sis aim to indicate the safety status, or risks, Marono (Marono et al., 1998). To retrieve the risk coverage area of commonly used Sis, both the tools, as well as the data they are based on have to be known. The relations between data, tools, and indicators are depicted graphically in Figure 10.

The purpose of hazard analysis and risk assessment ia the chemical process industry is to (/) characterize the hazards associated with a chemical facihty (2) determine how these hazards can result in an accident, and (J) determine the risk, ie, the probabiUty and the consequence of these hazards. The complete procedure is shown in Figure 1 (see also Industrial hygiene Plant safety).

A leader in applying PSA to other parts of the chemical process industry has been the AlChf. s Center for Chemical Process Safety. A major difference between PSA for nuclear power and PSA for chemical processing has been the lack of government regulations that require risk analysis for chemical processes. A primary impetuous has been the Occupational Safety and Health Administration s (OSHA) PSM rule that defines the application of PSA to the chemical industry for ihc proteciion of the public and workers. In addition, the Environmental Protection Agcrii, . (EPA) regulates waste disposal. 

I am a physicist who switched to nuclear engineering for my Ph D. My introduction to PSA was as an original participant in the Reactor Safety Study in 1972. Material for this book was first gathered in 1974 for a workshop on what to expect in WASH-1400 (the results of the Reactor Safety Study). Materials were gathered over the years for EPRI, Savannah River Laboratory, and other workshops. A culmination was in 1988 with "Probabilistic Risk Assessment in the Nuclear Power Industry" with Robert Hall as coauthor. This book updates these materials and adds material on PSA in the chemical process industry. I prepared the material for printing using a word processor... 

It was not nndl the 1950s that detonation flame arresters made of crimped metal ribbon elements were developed and began to be used more freqnendy (Binks 1999). The major impetus for die use of crimped metal ribbon detonation flame arresters in the US was the enactment of clean air legislation (Clean Air Act of 1990) which inadvertently created a safety problem by requiring reductions in volatile organic compound (VOC) emissions. To do this, manifolded vent systems (vapor collection systems) were increasingly installed in many chemical process industry plants which captured VOC vapors and transported them to suitable recovery, recycle, or destruction systems. This emission control requirement has led to the introdnction of ignition risks, for example, from a flare or via spontaneous combustion of an activated carbon adsorber bed. Multiple...

Accident precursors pro-active identification of safety risks in the chemical process industry / by Patrick Maria Wilhelmus Korvers. - Eindhoven Technische Universiteit Eindhoven, 2004. - Proefschrift. 

With the developed concepts, a number of field experiments were conducted in the chemical process industry. A first experiment was carried out in a small company in The Netherlands. From this first trial, it was evident that the concepts of precursors, the model of the organisational control process and the structure of these concepts had to be adapted to obtain better and more reliable results. The improvements led to the development of a structured protocol of seven clearly defined stages. By applying this 7-stage protocol to the data of the small company, safety risks could pro-actively be identified and the accidents which the company had already experienced, could be explained. 

The research described in this thesis deals with safety management in complex and high-risk organizations. Companies in the chemical process industry handling hazardous substances are chosen as the subject of study. In particular this thesis will focus on the current safety indication process, and how this safety indication process works and its shortfalls. An unreliable indication process, leads automatically to wrong reactions and measures to prevent possible accidents. Increased understanding of this process helps in providing a better basis from which effective measures to prevent accidents can be derived. 

Today there is still a problem indicating safety in high potential risk organizations such as the chemical process industry. Chapter 1 showed an example of how an accident could occur in the chemical process industry even though all safety measures... 

The risk matrix will be used to find a possible link between Sis and accidents which have occurred recently and attempt to establish why in spite of the presence of so many Sis accidents still occur in the chemical process industry. Therefore, in the next sub-Section, the most commonly used Sis are discussed and the data (events) they are constructed from are displayed in the risk matrix. Subsequently, this leads to the first risk coverage area, that of events Sis use to indicate safety.

Impurities in drug substances and drug products continue to be a source of great concern, discussion, debate, and research. " These concerns and debates typically center on the potential safety risks associated with impurities due to contamination and the setting of acceptance criteria. However, the bulk of the work being performed in the pharmaceutical industry, with respect to impurities, is focused on the isolation, identification, qualification and quantification of impurities that are found as a result of the manufacturing process or through chemical decomposition. On the...
