A key feature of self-reinforcement is that increasing the external/internal forces intensifies the system's response against these forces. As a result, the driving net force towards precipitating failure is reduced. In many cases, the self-reinforcement mechanisms achieve remarkable reliability increase at no extra cost. Two principal ways of self-reinforcement have been identified: reinforcement by capturing a proportional compensating factor and reinforcement by using feedback loops. Mechanisms of transforming forces and motion into self-reinforcing response have been introduced and demonstrated through appropriate examples. Mechanisms achieving self-reinforcement response by self-aligning, self-anchoring and self-balancing have also been introduced. For the first time, the potential of positive feedback loops to achieve self-reinforcement and risk reduction was demonstrated. In this respect, it is shown that self-energising, fast growth and fast transition provided by positive feedback loops can be used with success for achieving reliability improvement. Finally, a classification was proposed of methods and techniques for reliability improvement and risk reduction based on the method of self-reinforcement.","PeriodicalId":35420,"journal":{"name":"International Journal of Risk Assessment and Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46392331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology illustrated here is composed of three steps: 1) signal identification; 2) signal evaluation and prioritisation and when necessary; 3) assessing follow-up actions for further risk management measures. During signal identification, new information with regard to adverse effects induced by the potential NERC is gathered using various information sources. Based on collected additional information, the causality between chemical exposure and the adverse effect is evaluated and prioritised. Finally, for those NERCs where there is sufficient proof of the causality with an adverse effect or the need for action, an analysis of possible appropriate regulatory risk management options is made. With this approach, NERCs can be efficiently identified with timely recommendations of follow-up steps, to reduce or eliminate the risk of the substance.","PeriodicalId":35420,"journal":{"name":"International Journal of Risk Assessment and Management","volume":"21 1","pages":"248"},"PeriodicalIF":0.0,"publicationDate":"2018-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJRAM.2018.093763","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45874633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The radiography devices are operated manually by rotating the control unit to project the gamma source outside the shielding, in a projection sheath. Deviation from the standard operating procedures or malfunctioning of the gamma radiography equipment may result in potential exposure to occupational workers. Probabilistic safety assessment has been carried out to calculate the probabilities of potential exposure to occupational workers in industrial gamma radiography practice in India. Fault trees have been designed for failure assessment of radiation area monitoring instruments, the functionality of which is crucial to ensure safe industrial gamma radiography operations. Operational procedures leading to the potential exposure scenarios have been sequenced in the event tree. The probability of most severe potential exposure category is calculated as 3.506E-04 for open field radiography operations and slightly lower value of 1.293E-04 for enclosed radiography operations. Assessment results identify the contributory factors to potential exposure, along with their relative contribution. Results indicate that probability of potential exposure can be reduced by adopting safe work practice by operators and responsible attitude of radiological safety officers towards trainees and untrained persons.","PeriodicalId":35420,"journal":{"name":"International Journal of Risk Assessment and Management","volume":"21 1","pages":"232"},"PeriodicalIF":0.0,"publicationDate":"2018-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46162662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It uses a case study approach with a combination of work breakdown structure and fault tree analysis to identify risk factors in repairs and modernisation projects. Fifty two risk factors have been identified. Risk factors such as damage to household goods during shifting, injury to the labourers during shifting household goods, damage to household goods during packing, damage to household goods during unpacking and accidents during shifting of household goods have been found typical for small to micro construction firms involved in repairs and modernisation of residential houses. The suggested risk treatment reflects the lite version of project management and is validated by discussing with construction professionals and owners of small and micro construction firms. Risk retention, risk sharing and risk prevention are recommended for treatment of risks. This study is qualitative in nature and its scope is limited to Indian context only.","PeriodicalId":35420,"journal":{"name":"International Journal of Risk Assessment and Management","volume":"21 1","pages":"184"},"PeriodicalIF":0.0,"publicationDate":"2018-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66700899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whereas the industrial enterprises assume greater controls in managing their internal environs, the evident responsibility of governments is to regulate the business surrounding risks, to optimise the external environments, and to deliver poses that are conducive to business. In such context, this paper presents a specialised approach – Risk Leveling – which embraces a focused risk management concept as well as an explicit risk management methodology. Risk Leveling accentuates upon organised and efficient consumption of available resources to achieve balanced risk postures in the business contagious environment. The ultimate intent of Risk Leveling is not only to cut the risks to business acceptability limits but to also ensure that mutual risk parities are conserved. Such intent is pursued through an organised procedure which employs a mix of analysis tools and philosophies including the AHP and the ALARP. By settling the contextual risks to business acceptability bounds, Risk Leveling aims to facilitate the regimes in regulating the macro business environments for wellbeing of business.","PeriodicalId":35420,"journal":{"name":"International Journal of Risk Assessment and Management","volume":"21 1","pages":"135"},"PeriodicalIF":0.0,"publicationDate":"2018-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43278236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
