Frequent probability

Choice of Method. The particular method to be used depends to some extent on the compound to be prepared. On the basis of yield, the N-nitrosoacetyl method is generally to be preferred. However, the diazo reaction has been employed frequently, probably because it is less troublesome to carry out.

Risk the probabihtyofoccurrence and the severity of a mishap. There are six probabihty levels Frequent, Probable, Occasional, Remote, Improbable, and EUminated. There are four severity levels Catastrophic, Critical, Marginal, and Neghgible. The levels form a risk assessment matrix, shown in Figure 36-1. 

A drug which, by its actions on the heart, increases cardiac output and which is therefore used in the treatment of heart failure. It has to be used cautiously because of toxic effects. Elderly patients are particularly sensitive and overdosage occurs frequently, probably due to impaired renal function. Measurement of serum levels is therefore a useful guide to treatment. It can be measured by radioimmunoassay or enzyme-immunoassay. 

The next significant step in risk assessment procedure is to define occurrence probability. ISO 22201-2 already developed this table for moving walks (Table 2). There are six categories of frequency frequent, probable, occasional, remote, improbable and negligible. The same categorization is suggested by ISO 14798. 

In most cases it is not possible to exactly measure the risk or its components. Instead quahtative severity levels (negligible, minor, serious, critical and catastrophic) and semi-quantitative probability levels (frequent, probable, occasional, remote and improbable) are used [Fig. 3], It is the task of the domain experts to assign the appropriate attributes based on their knowledge and experience. Especially considering security risks, this is a very difficult task, since not only rehable statistical numbers are missing but also because of lack of experience. 

The bending strength, also known as the flexural strength or modulus of rapture (MOR), is also a characteristic that is determined on refractories very frequently, probably as frequently as the compression strength.
