Quantitative risk assessments are designed to evaluate the likelihood and consequences of hazardous events quantitatively, focusing on numerical estimates of risk. The process typically involves several components including hazard identification, exposure assessment, and risk characterization.

While site assessments are critical in understanding the context of a risk assessment, they often serve as a preliminary step rather than a direct component of the quantitative risk assessment itself. This is because quantitative assessments primarily focus on the mathematical and statistical analysis of data regarding hazards and exposures rather than on the qualitative aspects of specific locations or conditions. A thorough site assessment may inform the process, but the core quantitative analysis does not require it to be included in the framework of the assessment.

In contrast, hazard identification helps in determining what potential hazards need to be evaluated, exposure assessment analyzes the degree to which people or environments might encounter the identified hazards, and risk characterization synthesizes the findings to provide a clearer picture of risk. Each of these elements contributes directly to the quantitative aspect of the evaluation, making their presence essential in the overall assessment process.
