High-risk applications

This type of caution approach is essential in high risk applications since only certain plastics can be used as the basis for such applications. This chapter has been concerned with the problems of the product in use under the types of environments and potential abuse that may be encountered, and how the designer can prevent premature product failure which is one of their major responsibilities. 

It is necessary to screen out as many potential high-risk applicants as possible. It s important to imderstand that you have total control over who you hire. 

Inherently high-risk applications, which should be avoided or undertaken with caution and full understanding of the risks. 

ASME PCC-2 Article 4.1, Non-metaUic Composite Repair System for Pipehnes and Pipework High Risk Applications, 2006. 

ASME PCC-2 doesn t define any repair class but has two different articles about nonmetallic composite repairs. Article 4.1 talks about high-risk applications and Article 4.2 talks about low-risk applications. 

PROBLEM DEFINITION. This is achieved through plant visits and discussions with risk analysts. In the usual application of THERP, the scenarios of interest are defined by the hardware orientated risk analyst, who would specify critical tasks (such as performing emergency actions) in scenarios such as major fires or gas releases. Thus, the analysis is usually driven by the needs of the hardware assessment to consider specific human errors in predefined, potentially high-risk scenarios. This is in contrast to the qualitative error prediction methodology described in Section 5.5, where all interactions by the operator with critical systems are considered from the point of view of their risk potential. 

Electroconvulsive therapy (ECT) is the application of prescribed electrical impulses to the brain for the treatment of severe depression, mixed states, psychotic depression, and treatment-refractory mania in patients who are at high risk of suicide. It also may be used in pregnant women who cannot take carbamazepine, lithium, or divalproex. 

As discussed in Chapter 4, some risk-based decision making can benefit by the development of tolerance criteria for the various types of risk to which building occupants may be exposed. When identified risks are higher than what can be deemed tolerable, they should be eliminated or reduced to control the company s risk exposure. The process of risk identification and evaluation, comparison to tolerance criteria, and elimination or reduction of intolerably high risk is known as risk management. Figure 6.1 illustrates this process. Application of these tolerance criteria helps protect building occupants and ensure that resources are appropriately applied. 

Genetic applications of molecular technologies have different concerns than routine clinical laboratory testing because results are used in a predictive manner (e.g., the probability that a gene is present and, if present, whether it will be expressed and to what extent of severity). Therefore, validation procedures may differ, depending on whether the test will be used in high-risk situations or in the general population. 

Scalability of the systems is a must and the use of low MOI strategies is obligatory if the goal is the industrial application. Complex feeding strategies must be avoided since they impose high risks, and costs, to the overall process. 

Superficial skin infections are treated without antibiotics. Local hygiene and disinfection with alcohol prevents spread of furunculosis. Local application of gentian violet in water (1%) is effective for impetigo. All pus collections must be drained by puncture or incision. Antibiotics are required only when systemic signs of infection are present or in patients with a high risk of complications (e.g. to prevent bacteraemia in a patient with prostheses or intravascular devices). 

The many worst-case assumptions built into cancer risk assessments are there because of policy decisions, not because of scientific ones, and they confuse attempts to allocate money effectively for public health. For example, EPA estimates of synthetic pesticide residues in the diet have used the theoretical maximum human residue that is anticipated under the most severe field application conditions, which is often a large overestimate compared to the measured residues in food. Despite the EPA s estimated high risks from exposures to several pesticides, the U.S. Food and Drug Administration detected no residues of those pesticides in the food samples in its Total Diet Study.59...
