Deductive risk analysis methods

This type of hazards analysis can be either deductive or inductive. A deductive (top-down) analysis is one that first defines an undesirable event, and then considers what events and chains of circumstances are needed to occur before the overall undesirable event occurs. A deductive approach is used by detectives to solve crimes. A widely used type of deductive analysis in process risk analysis is the fault tree method, described in the next chapter.

Methods of formaldehyde analysis include the iodometric, sulfite [31], and mercurimetric [32,33] methods. The sulfite method measures only the formaldehyde present, whereas the iodometric method can also estimate the methylol groups. Another method is based on the partition of formaldehyde between water and isoamyl alcohol [34]. Estimation of the formaldehyde in the alcohol phase of a mixture of an aqueous solution of the resin and isoamyl alcohol allows deduction of the amount of free formaldehyde. This procedure has the advantage that no risk of reaction arises between free formaldehyde and the resin components. 

Method for Error Deduction and Incident Analysis (MEDIA) is a newly developed taxonomy based HOE risk quantification technique (Ahmad et al. 

In this section, the Method for Error Deduction and Incident Analysis (MEDIA) methodology is applied to human and organizational factors assessment. A combination of Failure Mode, Effects and Criticality Analysis (FMECA) and MEDIA will be presented for pigging operations. Risk quantification of this assessment is based on the results of statistical analysis of past accidents as explained in section 2.
