Quantitative assessment, of risk

CEFIC Views on the Quantitative Assessment of Risks from Installations in the Chemical Industiy, European Council of Chemical Manufacturers Federations, Brussels, Belgium, April 1986. 

Different techniques are currently available in human and ecological risk assessment to help in assessing the risks of the 4 mixture types. These techniques are indicated in Figure 5.11. Ecological techniques are placed in the upper left part of the diagram, and human techniques in the lower right part. Distinction is made between techniques that are used to derive safe levels and techniques that are used for quantitative assessment of risks. The techniques are discussed in more detail in the following sections.

Hazard Analysis. Recognizing that no plant can be perfectly safe, modem safety engineering has turned to techniques for the formal or quantitative assessment of risk [58]. Many techniques for formal analysis now exist [59,60]. They differ widely in scope and intention, and the Center for Chemical Process Safety [59] tabulates for each of them ... 

The approach described in this chapter is developed from extant practice and can provide the nanomaterial user an initial framework from which to develop responsible risk management strategies. Likewise, insurance carriers can use the framework as an informational tool for developing policy analyses and for assessing potential clients. The combination of the framework with decision analysis tools such as MCDA can provide quantitative assessments of risk amidst significant uncertainty.

Risk assessment considers the consequences of potential hazards, faults, failures, and accident scenarios. In particular, it provides a quantitative assessment of risk in contrast to other approaches (e.g., a HAZOP study) that provide qualitative assessments. Because industrial processes are complex and interconnected, risk assessment determines overall failure probabilities from those of individual components. For example, the failure... 

The extent to which chemical containment may contribute to a risk target being met is usually technically demanding and quantitative assessments of risk are difficult. Alexander McKinley consider how a conservative approach can be used to ensure that the presumed impacts on risk are defensible. They describe how chemical containment was taken into account...
