System Risk

There is no conclusive evidence that moderate, long-term use of cannabis causes lasting damage to physical or mental health. However, it is probable that frequent inhalation of cannabis smoke over a period of years will contribute towards bronchitis and other respiratory disorders and possible cancers of the lung and parts of the digestive system. Risks are greater if cannabis is smoked with tobacco.

Risk analysis has been proven to retain the flexibility necessary to make it a useful model system for addressing the countless issues that are found to be associated with plant-derived pharmaceuticals (Wolt and Peterson, 2000). Over the past few years, a great deal of information and experience has steadily accumulated with respect to risk analysis of pharmaceuticals that are currently produced in bacterial and aifimal cell bioreactor systems. Risk analysis has also been performed on transgenic crops used for food production as well as for other applications. As a result, elements from each of these disciplines can be incorporated into the design of optimal production and testing policies and practices. Risk analysis has been employed to cover a series of important issues regarding the large-scale manufacture of plant-made biopharmaceuticals, and will continue to present serious issues for researchers in the academic, corporate, and public health arenas to address (Miele, 1997 Ciliberti and Molinelli, 2005). 

Summary Assessment of the Safety, Health, Environmental and System Risks... 

For network implementation purposes, the first decision is whether the network is considered an open or a closed system. The open/closed system issue will drive the technological and procedural controls that need to be considered during the system implementation, and that need to be addressed as part of the system risk analysis. 

Software development is one of the most risk-prone management challenges. Risk factors can negatively impact the development process and, if ignored, can lead to project failure. To counteract these factors, system risk must be actively assessed, controlled, and reduced on a routine basis.1... 

Risk is defined as the probability of an undesirable event occurring and the impact of that event if it does occur. The result of this analysis will influence the degree to which the system development, implementation, and maintenance activities are performed and documented. By evaluating the system risk analysis, the system owner may uncover potential problems, which can be avoided during the development process. The chances of a successful, if not perfect, system implementation are improved.

Renewable energy resources have special attractive attributes. Renewable resources are more modular, even when developed in a centralized situation. Most biomass and geothermal plants are less than 100 MW. Wind turbines are physically separated and thus stand as separate risks. Fifty MW of wind turbines in one wind farm cover a large area. The loss of a single turbine has minimal impact on the system, and there is no fuel supply delivery system risk. 

Limited local inhibition of these transporters by using polymeric inhibitors could reduce such systemic risks and side effects. Efflux pump modulating polymers and surfactants mentioned in this review have been distinguished between nonionic, ionic and thiolated polymers.

In addition to the main document, a number of additional guidance documents have been published during recent years. These include an article in Pharmaceutical Engineeringf about a risk-based approach to computer validation. The article starts from the risk assessment given in GAMP 4 and provides a model for a system risk assessment based on the risk level of the business process supported by the system and the system vulnerability. As an outcome of this assessment, it summarizes which validation activities are appropriate for which risk level. 

The system risk assessment is seen by the authors as one step of risk assessment when the system produces electronic records. The second part would be an assessment of the risks to the records stored in the system. Very recently, a new guidance document on a risk-based approach to e-records and signatures was published, focusing more on the risks related to records and signatures once they are maintained electronically, and proposes risk mitigation strategies for several types of records based on their risks.

It is remarkable that no cardiovascular complications were recorded in this study. Medical publications report that when a person is exposed rapidly to a sulEcient quantity of phenol (in general, 3-4 g of phenol applied quickly to the face), abnormal heart rhythms may occur. These abnormalities appear 15-20 minutes after the beginning of the peel and are often rapidly reversible. If any arrhythmia had developed during these cases of poisoning, it would no doubt have occurred rapidly and disappeared again by the time the patient arrived at the hospital. This argues in favor of the autonomous reversibility of arrhythmias with phenol. The authors cautiously conclude The absence of serious toxicity and major chemical burns in this series does not eliminate concern with the corrosive and systemic risks of phenol poisoning .

The training of professional personnel in the risk assessment process is an ongoing activity at EPA. However, classroom training is only a partial answer to EPA s risk assessment dilemma. It lessens, but has not eliminated, the pressure of EPA to review technical reports with less experienced professional personnel. The development of a computer software system, Risk Assistant, to assist environmental personnel in conducting risk assessments and reviewing assessments generated by contractors, represents a complementary approach to increasing the technical quality and consistency of risk assessments.

As we mentioned in the previous chapter, its approach used a codification system (Risk Phrases) that was based on toxicological evidence of harm arising from exposure to substances. Criteria for codification were set out in Annex VI to the Dangerous Substances Directive (67/548/EEC) as amended by its Seventh Amendment (92/32/EEC). Annex I to the Dangerous Substances Directive included risk phrases (R-phrases) for all substances with an agreed hazard classification in the EU. This information was reproduced in the UK in the Approved Classification and Labelling Guide (Third Ed.) whilst specific substances and their R-phrases were listed in the Approved Supply List. If any substance supplied to a workplace within the European Community was not listed in Annex I to the Directive, the supplier was required to consider whether a hazard classification was appropriate and if so, based on the classification criteria, apply the appropriate R-phrases as well as other information. 

The TCR, published by ERA in 1989, requires all public water systems to monitor for the presence of coliforms (measured as total coliforms ) in their distribution systems. Coliforms serve as indicators of many enteric pathogens, and are therefore useful in determining the vulnerability of a system to fecal contamination. In reviewing microbial risks with a federal advisory committee, ERA determined that the available data on distribution system risks warranted further analysis. Potential revisions being considered m lead to the establishment of requirements to address the quality of finished water in distribution systems (ERA, 2004d).

Most accidents in well-designed systems involve two or more low-probability events occurring in the worst possible combination. When people attempt to predict system risk, they explicitly or implicitly multiply events with low probability— assuming independence—and come out with impossibly small numbers, when, in fact, the events are dependent. This dependence may be related to common systemic factors that do not appear in an event chain. Machol calls this phenomenon the Titanic coincidence [131]. ...
