The risk management process may involve the following steps risk classification, risk-benefit analysis of risk reduction options, implementation of risk reduction measures, and monitoring these measures (Van Leeuwen and Vermeire 2007).

In the following sections, we will discuss the sources of supply chain risks, risk identification and classification, risk prioritization, and risk intervention strategies.

When a block is inside, the entrance panel is closed and the inspection is ready to start. The inside of the stainless steel X-ray tubehead housing is clad in lead with an on/ofT shutter in front of a thin plastic X-ray window. The thin window is to ensure the IP 65 classification. The window is of plastic that is not affected by the cleaning agents. The on/off shutter is interlocked with the entrance and exit panels so X-rays can be kept on at all times without risk of radiation leakage or exposure of the frozen fish blocks prior to the actual inspection.

Substances or preparations requiring to be labelled with the risk phrase R45 (may cause cancer) or R49 (may cause cancer by inhalation) under CHIPS are listed in Table 5.16 after the 5th edition of the Approved Supply List (Information approved for the classification and labelling of substances and preparations dangerous for supply). This list excludes certain coal and oil-based substances which attract the phrase R45 only when they contain a certain percentage of a marker substance (e.g. benzene). 

Flammable solids and organic peroxides having, as tested, explosive properties and which are packed in such a way that the classification procedure would require the use of an explosives label as a subsidiary risk label. Dangerous goods listed in Table 15.9... 

A facility risk review (FRR) is intermediate between a qualitative HAZOP and a quantitative risk assessment (QRA) achieved by broad probability and consequence classifications. Although not a risk assessment, an FRR uses PSA to get optimum risk cost-benefit.

Generally, the slope factor is a plausible upper bound estimate of the probability of a response per unit intake of a ehemieal over a lifetime. The slope factor is used in risk assessments to estimate an upper-bound lifetime probability of an individual developing cancer as a result of e.xposure to a particular level of a potential carcinogen. Slope factors should always be accompanied by the weight-of-evidence classification to indicate the strength of the evidence that the agent is a human carcinogen. Calculational details are presented below. 

Kazarians, Boykin, and Kaplan investigated tlie risk of transporting an acutely toxic and flanunable chemical 400 miles in a specially equipped railroad tank car. During its journey, the tank car clianges trains in three major rail yards. Each change of trains is teclmically described as a classification . The chemical is generally shipped one tank at a time. There are approximately 150 shipments a year. 

Accident frequencies were evaluated separately for the two types of activity mainline transit and rail yard classification. When an accident occurs and the tank car is damaged, the severity of public exposure depends on several factors, including tlie likelihood of a breach in tlie tank car, the severity level of tlie release (i.e., tlie rale or volume of spillage), the likelihood of an explosion, tlie magnitude of tlie explosion, and die dispersion pattern of the unignited vapors. Recall tliat Part II of tliis book deals witli explosions and tlieir effects Part III treats tliis subject of dispersion. Table 21.3.1 smnmarizes tlie transportation risk data for tlie mainline and rail yard segments of tlie tank car journey.

A general illustration of how these criteria impact on the risk classification is shown in Figure 9.6. 

The previous chapter outlined how device classification and the use of standards provide the basis for effective regulation of medical devices, with particular focus on the application of design control standards to the development of devices. In this chapter we look at the process for evaluation and authorisation of devices, and see how the regulatory requirements vary depending on the perceived risk of the device as indicated by its classification. It will be noted that there is considerable variation between the approaches adopted in Europe and the US and that, compared to dmgs, practical harmonisation of requirements still remains to be adopted. 

Brief description of ventilation systems. More details should be given for critical areas with potential risks of airborne contamination (schematic drawings of the systems are desirable). Classification of the rooms used for the manufacture of sterile products should be mentioned.
