By way of an overview introduction, the chapter will provide an overall summary of the RMP, discuss the hazard analysis requirements to include consequence analysis, describe the prevention program requirements and the emergency response requirements, and finally discuss the risk management plan. 

Flowcharts are used for process overview analysis of causes and consequences, lines of defense, and testing data requirements and review of hazard checklist, schedule, and followup on recommendations. 

From the FIA—MS overview spectrum, speculation that there can be more than just one structurally defined molecule type behind an observable signal i.e. the presence of isobaric compounds, cannot be excluded whenever one signal defined by the m/z-ratio is examined in FIA-MS spectra. Consequently, the information obtained by FIA-MS is quite limited whenever we deal with complex mixtures of environmental pollutants rather than the analysis of pure products or formulations with a known range of ingredients. LC separation is inevitable when mixtures of isomeric compounds should be identified with MS-MS. Therefore, in FIA-MS-MS special attention has to be paid to avoid the generation of mixed product ion spectra from isomeric parent compounds. This would block identification by library search and may lead to misinterpretations of product ion spectra because of the fragmentation behaviour observed. 

Fire hazard analysis (FHA) is the process to determine the size, severity, and duration of a scenario and its impact on personnel, equipment, operations, and the environment. Chapter 5 provided details of performing an FHA. The following paragraphs provide an overview of the FHA process. For example, one scenario could be a seal failure where the material being released is ignited and afire results. In assessing consequences, several questions must be considered ... 

As far as simple modelling of self-assembly is concerned, the treatment of single component lipid molecules given here has probably been pushed as far as it can. The refinement of our theory of self-assembly requires a proper examination of Stern layers, consequences of deviations from liquid-like properties of hydrocarbon chains, head group steric elfects, specific ion adsorption and other effects. While such a more rigorous analysis would undoubtedly provide specific insights into the properties of particular molecules, it is doubtful if a more refined theory will provide a better overview. 

The second chapter is dedicated to properties and sources of radiation suitable for powder diffraction analysis, and gives an overview of the kinematical theory of diffraction along with its consequences in structure determination. Here, readers learn that the diffraction pattern of a crystal is a transformation of an ordered atomic structure into a reciprocal space rather than a direct image of the former. Diffraction from crystalline matter, specifically from polycrystalline materials is described as a function of crystal symmetry, atomic structure and conditions of the experiment. The chapter ends with a general introduction to numerical techniques enabling the restoration of the three-dimensional distribution of atoms in a lattice by the transformation of the diffraction pattern back into direct space. 

Before we discuss a combination of GED with other techniques it is convenient to give a brief overview of the electron diffraction method itself. Therefore, in subsection A we describe the experimental equipment currently in use, followed by the basic equations of GED (B) and structure analysis (C). As a logical consequence. Section III describes the changes in running the GED experiment, while Section IV characterizes those modifications, which are used in a combined structure analysis. 

The size-dependent energy gap may serve as a useful tool when designing materials with well-controlled optical properties, and a much more detailed analysis of this topic is available [62]. Before describing the physical consequences of the size-dependent band gap on the optical and electronic properties, however, a brief overview will be provided of how QDs may be fabricated in practice. 

Perhaps the area of analysis in which electrochemistry has had the biggest impact on society is in biosensors, notably the glucose biosensor [48], Although Volume 9 is concerned with bioelectrochemistry, it is important that this area of electroanalytical chemistry is represented appropriately in Volume 3. Consequently, Schuhmann and Bonsen provide an overview of the physical principles and appKcations of biosensors in Chapter 2.11. A comprehensive overview is given of amperometric, potentiometric, conducti-metric and impedimetric formats for biosensors, and the relative merits of each are fully assessed. Potential new directions are highlighted, particularly connected to miniaturization and multisensor array detection strategies. 

In order to get a complete overview of third party risks in the Netherlands, all pipeline owners are obliged to provide pipeline data to a national risk register (Sant van t 2008). Based on these data and taking into account the new zoning distances, an analysis of the consequences of these new zoning distances for land use planning was carried out. 

The overview of the NMR/LC—MS PDS is shown in Figure 18.2. Through the co-analysis of visualized MS and NMR data with signal amplitude covariation in the NMR/LC—MS PDS spectra, the intrinsic correlation between retention time (t ), mass/charge (m/z), and chemical shift (S) data of the same individual constituent in the LC fractions can be found. As a consequence, the complementary spectral information was obtained from mixture spectra for unambiguous structure identification of individual constituents in crude extracts.
