Considerable interest has been generated in hazard identification and risk analysis techniques, which provide a systematic means to help reduce and manage chemical process risks. CCPS has undertaken a series of Guidelines covering many aspects of the subjects to provide the latest information and useful techniques for the engineer in the...

In addition to an overview of government regulations, the book introduces the resources of the AICHE Center for Chemical Process Safety library. Guidelines are offered for hazard identification and risk assessment. The book concludes with case histories drawn directly from the authors experience in the field. 

In order to understand the use and intent of the various immunotoxicology regulatory guidelines and guidance documents, the difference between two concepts familiar to toxicologists should be emphasized. Hazard, identification refers to a method which is essentially qualitative that is, it is designed to detect the ability of a test article to produce a certain (in the context of toxicology) adverse effect, without reference to exposure issues. Risk assessment, on the other hand, takes into consideration method, dose, and duration of exposure, condition(s) of the exposed population, and concurrent... 

As mentioned previously, there are no test guideline methods for respiratory irritation. Good data, often clearly related to exposure levels, can be obtained on respiratory and mucous membrane irritation, from well-designed and well-reported inhalation studies in animals. Also the Alarie test (Alarie 1973, 1981), an experimental animal test assessing the concentration that results in a 50% reduction of the breathing frequency, may provide useful information on sensory irritation of the upper respiratory tract and the results may be used for hazard identification. 

The approach to hazard identification in the proposed revision of the cancer risk assessment guidelines (EPA, 1996a) differs from the...

The project s risk assessment effort followed ERA methods and established agency policy as outlined by the National Academy of Sciences (NAS, 1983) and established in final risk assessment guidelines (ERA, 1986). It involved four steps (1) hazard identification, (2) determination of dose-response relations, (3) evaluation of human exposme and, finally, (4) characterization of risks. 

The US government s new approach (2000) to health assessment of agents involves the iterative interaction of four major components basic scientific research (hazard identification), science-based toxicity/risk assessment (dose-response assessment), exposure assessment, and risk characterization (Figure 2). This section relies heavily on the US EPA guidelines for the health assessment of suspect developmental toxicants which describe how the government uses, and plans to use, developmental toxicity data as part of their weight-of-evidence approach to both the hazard identification and the dose-response assessment components of risk assessment.
