Definition Of

Osbra pipeline (Oleoduto Sa˜o Paulo – Brasi´lia), about 1000 Km long, is one of the main pipelines of Petrobras Transportes S. A. - Transpetro and its function is to carry gasoline, diesel oil, aviation kerosene and liquefied petroleum gas throughout the Center-West region of Brazil. As it crosses several states of Brazil (Sa˜o Paulo, Minas Gerais and Goia´s) and Federal District (Brasi´lia), the process of renewal of the environmental license at the federal level required a series of environmental studies. Accordingly, a new study is being performed, considering, in addition to the already consecrated Quantitative Risk Assessment, a new methodology for recognition and analysis of the vulnerable environmental elements along the pipeline right-of-way in what concerns oil spill. This study intends to present the aforementioned methodology according to the following topics: Characterization of the undertaking and of the surrounding region; identification of the notable points; identification of the sensitive environmental elements in the hydrographic basins; Preliminary Hazard Analysis; definition of accident scenarios; dimension of possible leaks along the pipeline right-of-way and their consequences (physical effects); calculation of frequencies; calculation and evaluation of risks (social and individual); classification of environmental sensitivity; contingency actions analysis and conclusions. Development of this work brings as a result a more detailed knowledge of the consequences of an occasional accident arising from pipeline related activities, to the end of preventing and protecting the vulnerable elements (man and environment) along the pipeline right-of-way.

Assessment Techniques

One of the components of the General Agreement on Tariffs and Trade Sanitary and Phytosanitary agreement that will have far-reaching effects on International trade in foods and food products is the requirement for countries to provide risk assessments as part of the process of resolving disputes that involve food safety issues. Risk assessment is a means of evaluating the likelihood and impact of hazards. It provides a framework for systematically considering available data, providing rationales for assumptions, and identifying areas where additional information is needed. While the application of quantitative risk assessment techniques to microbial food safety has been limited, recent studies have increasingly demonstrated its feasibility. Quantitative risk assessment is particularly well suited for use with the hazard analysis critical control point and appears to have potential as an approach for comparing the equivalence of international food safety programs and inspection systems.

The Impact

One of the goals of any oil terminal is to make a business while avoiding hazardous events and harmful effects for both humans and the environment. This can be achieved by creating a safe working place as well as by performing safe and acceptable activities regarding the impact on surrounding objects, including residential and industrial areas. The aim of the hazard analysis of the oil terminal is to assess the risks related to hazardous events or phenomena and to evaluate whether the assessed risks are acceptable. The hazard analysis and assessment of risk are also used for risk reduction while examining and limiting hazardous scenarios that, for instance, involve the loss-of-containment of flammable or combustible material. In this paper, the authors aim to contribute to risk research by providing a comprehensive methodology of risk assessment for oil terminals with case study results and discussion on features of the methodology, risk aggregation, its applicability for risk reduction, and industrial interests. The performed study considered the “Klaipedos Nafta AB” (an operator of the Klaipeda Oil Terminal, Lithuania) case study regarding hazardous materials that might be released from various tanks, devices, and associated pipelines. The performed quantitative risk assessment has enabled the determination of the probability regarding whether releases would ignite and, for instance, cause explosion. In the case study, the estimate of probability, i.e., the frequency, and the possible consequences of the hazardous events were evaluated, and both mitigation and risk reduction measures were also considered.

The Impact

Based on the tunnel environment and the characteristic of flammability and explosion of liquefied petroleum gas (LGP), the leak of LPG tanker can induce heavy casualties and property loss in the tunnel. In order to study quantitative risk of LGP transportation in road tunnel, the data of 599 accidents and 659 accidental vehicles are collected. From these data, the proportion of LGP tanker accident in the total accident vehicles and million vehicles kilometer (MVK) tanker accident rates are obtained. By analyzing the leakage scene of LGP tanker, the possible accident types of the LGP transportation were analyzed, such as boiling liquid expanding vapor explosion (BLEVE), vapor cloud explosion (VCE), flash fire and jet fire, etc. The impact of leak time to various ranges of injury is studied in the condition of LGP continued leakage. The slight injury, serious injury and death radius of LGP leakage accidents are calculated in tanker loaded with different LGP quantity. In view of the accidental analysis, the countermeasures will be proposed to reduce the risk of LGP transportation in road tunnel.

The Impact

We developed a quantitative microbiological risk assessment (QMRA) of haemolytic uremic syndrome (HUS) associated with Shiga toxin-producing Escherichia coli (STEC)-contaminated beef (intact beef cuts, ground beef and commercial hamburgers) in children under 15 years of age from Argentina. The QMRA was used to characterize STEC prevalence and concentration levels in each product through the Argentinean beef supply chain, including cattle primary production, cattle transport, processing and storage in the abattoir, retail and home preparation, and consumption. Median HUS probability from beef cut, ground beef and commercial hamburger consumption was <10−15, 5.4x10-8 and 3.5x10-8, respectively. The expected average annual number of HUS cases was 0, 28 and 4, respectively. Risk of infection and HUS probability were sensitive to the type of abattoir, the application or not of Hazard Analysis and Critical Control Points (HACCP) for STEC (HACCP-STEC), stx prevalence in carcasses and trimmings, storage conditions from the abattoir to retailers and home, the joint consumption of salads and beef products, and cooking preference. The QMRA results showed that the probability of HUS was higher if beef cuts (1.7x) and ground beef (1.2x) were from carcasses provided by abattoirs not applying HACCP-STEC. Thus, the use of a single sanitary standard that included the application of HACCP-STEC in all Argentinean abattoirs would greatly reduce HUS incidence. The average number of annual HUS cases estimated by the QMRA (n = 32) would explain about 10.0% of cases in children under 15 years per year in Argentina. Since other routes of contamination can be involved, including those not related to food, further research on the beef production chain, other food chains, person-to-person transmission and outbreak studies should be conducted to reduce the impact of HUS on the child population of Argentina.

Safety is a high priority for any rail system, and there are several safety concerns associated with operating passenger and freight trains on shared-use rail corridors. Adjacent track accident (ATA) is one of the most important concerns. ATA refers to train accident scenarios where a derailed equipment intrudes adjacent tracks, causing operation disturbance and potential subsequent train collisions on the adjacent tracks. Other ATA scenarios include collisions between trains on adjacent tracks (raking), turnouts, and railroad crossings. Limited literature is available that addressed the risk of ATA for shared-use rail corridors. The research described in this paper presents a comprehensive risk assessment to identify factors affecting the likelihood and consequence of adjacent track accidents. A discussion on how these factors affect the probability, consequence, and how individual factor relates to each other are provided. A semi-quantitative risk analysis is developed to investigate various factors affecting train accident rate, intrusion rate, and accident consequences. This research intends to depict a high-level overview of adjacent track accidents and provides a basis for future quantitative risk analyses and risk mitigation implementations.
