Assess Chemical Reactivity Risks

To the degree that chemical hazards are identified and understood (Sections 4.2 to 4.4), and to the extent that the facility has been designed or is currently operational, facility-specific risks can be analyzed. 

in this context, is a combination of the likelihood and the severity of losing control of chemical reactivity hazards, taking prevention and mitigation safeguards into account. 

The goal of assessing risk is to build on the knowledge of chemical reactivity hazards, to understand how the hazard properties may lead to loss scenarios in the facility context, and to determine whether existing safeguards are adequate. Therefore, the assessment of risk can be performed at any stage of facility design, development, operation, or alteration. Of course, the more that is known about the facility and its equipment and operation, the more detailed the risk assessment can be. Methods used to determine chemical reaction risks are varied, as are their objectives and data requirements. 

Consequence Assessment/Appropriate Design Basis Determination 

Consequence assessment for the purposes of establishing design basis differs from consequence assessment in the context of a risk analysis study (see Qualitative and Quantitative Methods, below). A qualitative, or semi-quantitative (order of magnitude) consequence severity estimate may suffice for the latter.
