Safety and environmental information is needed to provide a basis for implementation of further program components such as operating procedures and hazards analysis. Specific guidelines as to what information is needed are contained in API RP 141. 

An application of transport and compartment-type models to hazard analysis is described in the paper by Honeycutt and Ballantine (19). The compound CGA-72662 running off from agricultural areas into surface waters was modeled in order to set safe application procedures consistent with the protection of aquatic environments. Patterson, et al (2 0) have adapted the UTM model to a software package that is generally applicable to fate assessments of toxic substances in air, water, soil and biota. Their work, now in working draft form, is being used by Dr. William Wood and Dr. Joan Lefler in the Office of Toxic Substances of the U.S. Environmental Protection Agency. 

Partial what-if analyses for the two example processes described in Section 4.0 are shown in Tables 4.9 and 4.10. Although for actual, more complex analyses, the what-if tables for each line or vessel would be separate, for these examples, a single table was developed. A preliminary hazard analysis (PHA) would identify that the intrinsic hazards associated with HF are its reactivity (including reactivity with water, by solution), corrosivity (including carbon steel, if wet), toxicity via inhalation and skin contact, and environmental toxicity. The N2 supply system pressure is not considered in this example. The specific effects of loss of containment could be explicitly stated in the "loss of HF containment" scenarios identified. Similarly, the effects of loss of chlorine containment, including the reactivity and toxicity of chlorine, could be specified for the second example. 

A full-scale Design Project would include an operability study followed by appropriate hazard analysis. For the purposes of this examination, candidates are only required to make recommendations to minimize environmental pollution during operation of the plant.

Specify the toxic or nontoxic character of the main chemicals involved in the process. Information on toxicity and hazard effects can be found on the websites of agencies for public environment and health, such as for example the US Environmental Protection Agency (EPA) and the European Environmental Agency. A good introduction to environmental engineering is the book of Allen and Shon-nard [4]. In the field of process safety, the book of Crowl and Louvar [5] is still popular. The book of Kletz [6] covers the topics of hazard and operability, as well as hazard analysis.

Recently, SPME has provided many improvements as the cleanup step of complex samples, particularly for the analysis of volatile compounds by headspace techniques [8]. SPME is a solventless extraction and concentration technique which has advantages as a simple and economic technique that reduces health hazards and environmental issues. 

Human loudness perception depends in a complex manner on both frequency and the overall loudness of sound. (For example, bass is more difficult to hear in music played at low volume than in the same music played at high volume.) To capture this behavior, two weighting scales have been developed for use in sound hazard analysis. The most common of these is the A weighting scale, which is commonly used to assess occupational and environmental noise. The A scale weights sounds in the 1000-6000 Hz range much more heavily than low-frequency sounds. The A-weighted intensities (dBA) of some common sounds are listed in Table 5. By contrast, the C weighting scale is used for very loud sounds and is a much flatter function of frequency.

The engineering aspect regarding environmental protection and safety are specialised topics that cannot be treated properly here. As general introduction in environmental engineering we recommend the book of Allen and Rosselot (1996). In the field of process safety the book of Growl and Louvar (1989) is very popular. The topics of hazard and operability (Hazop), as well as hazard analysis (Hazan) are covered in a book due to Kletz (1992). A concise presentation of these issues sufficient for a student project may be found in Coulson Richardson vol. 6 (Sinnott, 1993). 

Hierarchical Approach is a simple but powerful methodology for the synthesis of process flowsheets. It consists of a top-down analysis organised as a clearly defined sequence of tasks grouped in levels. Each level solves a fundamental problem as, number of plants, input/output structure, reactor design and recycle structure, separation system, energy integration, environmental analysis, safety and hazard analysis, and plantwide control. At each level, systematic methods can be applied for the synthesis of subsystems, as chemical reaction, separations, or heat exchangers network. 

SWIFT, as with many hazard analysis methods has its origins in industry and manufacturing. The guidewords originally conceived lend themselves to the management of raw materials, environmental release of chemicals, etc. In HIT the technique holds true but guidewords need to be modified. Card, Ward and Clarkson propose an alternative set of guidewords for SWIFT [1] ...
