Risks falling

For risks falling below the line, efforts might be made to further reduce the risks so that they are as low as reasonably practical (ALARP). In other words, activities with risks in the ALARP region are candidates for further risk reduction to the extent such risk reduction can be justified by the additional resources required to achieve it. Figure 4.1 implies that for Higher risk activities in the ALARP region (those closer to the intolerable level), it may be appropriate to expend, proportionately, more resources for risk reduction than for those with lower risks. At some point, the risks become... 

NMR-associated risks fall into three categories (1) magnetic fields, (2) cryogens and (3) sample-related risks. If you re picky, then you could also add things like risk from electrical shock, etc., but I m sure that you re not ... 

Begin with cycles that use small investments to tackle issues that represent high project risk. Typically, these risks fall into two categories requirements and technical architecture. More resources can be fed into successive cycles as confidence is gained. The idea is fractal a big project s single cycle can be composed of several smaller cycles of sub-projects. 

Assumed Risk— A risk that has been identified, analyzed, and accepted at the appropriate management level, unanalyzed or unknown risks fall under oversight and omissions by default. 

Fig. 15.1 Hazard and risk. The tiger behind bars is the hazard, as it could lead to harm. The risk is the probability that an adverse outcome will occur in unit time, or for some other specified denominator, such as per caged tiger. The perceived risk is the man s intuitive estimate of the risk. He may express it (more dangerous than crossing the road ) or reveal it, by avoiding the tiger s cage, even if he risks falling into the penguins pool.

Once agreement has been reached on the severity and probability classifications, an idea of the risk can be obtained. A matrix approach is usually used to do this. An example is shown in Figure 4. An organisation may decide, as a matter of policy, to devote resources to addressing risks falling in the medium and high categories. 

In general it has been suggested that, in medical cases, concern ceases when risks fall below about 1 in 100000 so that the procedure then becomes regarded as safe. In such cases, when disaster occurs, it can be difficult indeed for individuals to accept that they deliberately accepted a risk they feel it should not have happened to me and in their distress they may seek to lay blame on others where there is no fault or negligence, only misfortune (see Warnings). 

In most of the world, HBV is the most common cause of acute viral hepatitis. As with HAV, most infections in children are clinically silent. An estimated 30% to 50% of adolescents and adults with acute HBV infection develop jaundice. The outcome in acute HBV infection is strongly influenced by age and immune status. In healthy adolescents and adults, an estimated 1% to 3% of cases will progress to chronic infection. In a person with immunosuppression, the likelihood of chronic infection increases to 10%. Neonates infected with HBV have a 90% likelihood of chronic infection, and the risk falls gradually over the first 5 years of life. 

Successful delivery is verified against the success criteria within the risk management plan. Several stakeholders may need to confirm this verification. The site owner or developer will wish to know that the proposed management of the site is acceptable and that any new site valuation can be supported. The regulator may have to confirm that residual risks fall below regulatory thresholds. Finally, but most importantly, site occupants need to know that any risks to them have been reduced adequately. 

The notion of de minimis risk is similar to that of ALARP. A risk threshold is deemed to exist for all activities. Any activity whose risk falls below that threshold value can be ignored— no action needs to be taken to manage this de minimis risk. The term is borrowed from common law, where it is used in the expression of the doctrine de minimis non curat lex, or, the law does not concern itself with trifles. In other words, there is no need to worry about low-risk simations. Once more, however, an inherent circularity becomes apparent for a risk to be de minimis it must be low, but no prescriptive guidance as to the meaning of the word low is provided. 

The calculated risk falls below the risk value applicable for death in the Netherlands for the individual risk at a distance of 8-9 m. This value is 1.0 X 10 a and applies for a duration of stay of 24 h (in reality it is therefore a location risk limit). The short range of 8-9 m justifies the choice of a pipe section of 10 m length initially made. 

In Figure 8 the acceptance criteria for the SR are shown. The range between the upper and lower tolerable level is the ALARP zone the risks falling in this region are considered as acceptable only if their reduction is not possible or cost effective. 

With the above mentioned data, the Level of Individual Risk falls, as shown in Figure 9 in the acceptable region (3.325E-11 fatalities/(passengers-km-year). 

Risk falling in between that stated previously for which duty-holder has to use judgment to reduce to ALARP. 

Risk assessment is not only concerned with injuries in the workplace but also needs to consider the possibility of occupational ill-health. Health risks fall into the following four categories ... 

Once risks have been identified and assessed, however, managing each of the risks falls into one or more of the following categories ... 

Wandering is also known as walking. It s not problematic unless risking falls, absconding or interference with other patients care. Allow wandering with a 1 1 nurse, who can gendy distract from potential risks. Use of restraints or bedrails may cause injury. 

If the degree of risk is 15-20, the safety officer needs to review the work procedure immediately, use appropriate safety measures to reduce the risk to a low level. Supervision by a competent person is also required. If the degree of risk falls in the range of 5-14, the safety officer needs to review the work procedure within a reasonable time. He needs to formulate safety measures to reduce the risk to a low level. If the degree of risk is within the range of 1, workers need to foUow in-house safety rules and statutory requirements. Nevertheless, if the control measures are unable to reduce the risk to a low level, the method statement shall be reviewed by the engineer. There should be re-assessment of risks according to the revised method statement and procedures.
