Ergonomics, safety, and resilience in the helicopter offshore transportation system of Campos Basin
Get PDFBACKGROUND: Air transportation of personnel to offshore oil platforms is one of the major hazards of this kind of endeavor.Pilot performance is a key factor in the safety of the transportation system.
OBJECTIVE: This study seeks to identify the ergonomic factors present in pilots’ activities that may in some way compromise or enhance their performance, the constraints and affordances which they are subject to; and where possible to link these to their associated risk factors
METHODS: Methodology adopted in this project studies work in its context. It is a merging of Activity Analysis (Guerin et al. 2001) of European tradition with Cognitive Task Analysis (CTA - www.ctaresource.com) articulated with the recent approaches to cognitive systems engineering developed by Professors David Woods and Erik Hollnagel. Fifty-five hours of field interviews provided the input for analysis.
RESULTS: Sixteen ergonomic constraints were identified, some cognitive, some physical, all considered relevant by the research subjects and expert advisers
CONCLUSIONS: Although the safety record of the personnel transportation system studied is considered acceptable, there is low hanging fruit to be picked which can help improve the system’s safety
Assessing risk in sustainable construction using the Functional Resonance Analysis Method (FRAM)
No full textTraditional tools found in occupational risk assessments are a preliminary hazard analysis and checklists,
both based on the isolation of a particular activity from the entire process and created for application in
specific environments of manufacture. This strategy makes the results of such evaluations distant from real situations. Construction is a complex endeavor and can involve multiple contractors and groups working under each contractor. Work occurs under constant change and varying demands. In this context, as workers move through their daily journey, their health and safety are often are threatened by activities carried out by other contractors or groups. The study utilizes the Functional Resonance Analysis Method (FRAM), which aims to describe how function couplings may be combined in such a way that variability of performance, rather than failure or poor functioning, creates an occupational risk. The study also contributes to the evolution of FRAM, by proposing the application of the analytic hierarchy process, to investigate the relative importance of the criteria and alternatives for the identification of phenotypes of performance variability, as well as the aggregation of variabilit
The meetings of disaster victims as a space for developing community resilience
Get PDFThe objective of this study is to analyze how the collective meetings held inMãeLuiza community have helped in increasing community resilience after a disaster. This is a case study related to the disaster in MãeLuizacommunity due to the heavy rains that hit the city of Natal in June 2014. The disaster was a landslide that culminated in a huge crater affectingaround200 families. The method was based on the community ergonomics framework. The meetings realized by community members after the disaster were followed and mediated by ergonomists to understand how the community deal with disaster management issues. It was found that the meetings become an important space for the disaster victims helping then for different purposes, such as: to get information about the real situation that they were; in clarify conflicting information; obtain guidance; identify and organize their real demands; discuss and decide on the strategies to be adopted; bring government officials and technicians to the community to clarify, discuss and resolve their; involve community leaders; schedule a public hearing in the municipal parliament; be represented in front of authorities and the media; establish alliances with sectors of society; experience the
collective participation, reflect and learn from their own experiences, and; monitor the decisions and actions taken by the authorities. We conclude from these results that the involvement and participation of the residents affected by the disaster in the meetings, following the decisions that needed to be taken in response to the disaster contributes to increasing the community resilience, as well as contribute to the development skills and to improve the interaction among individuals from the community
Study of photon attenuation coefficient in brine using MCNP code
Get PDFIn petroleum industry, multiphase flows are common and the relative salt content of the water component depends on the location of oil extraction. The salt present in the water component causes incrustations in the pipeline and may interfere in the flow measurement. This paper presents an elaborate model using MCNP code to simulate a narrow beam gamma ray source, a brine sample and a NaI(Tl) detector, with beam energies ranging from 59,54 keV to 662 keV. Through this model, we can relate the photon attenuation coefficient to the salinity of water. This model can be experimentally reproduced, and used to measure the salinity in situ without affecting the medium
Use of virtual simulator for agent training in radiation protection actions in major events
Get PDFWith the proximity of the events of the Olympic Games, Brazil can become a great place of visibility for running dirty bombs or any other radiation mode proliferation by terrorists. Aware of these problems, the government and the organizations created managements of emergencies to ensure that these events elapse in an orderly and safe manner. The management of emergency situations at an event is a complex problem, which involves dynamic, unforeseen and unintended situations, emphasizing the potential complexity of the contexts in which organizations operate and, as a consequence, the people involved in the execution of multiple tasks from activities that require intense cognitive effort, are often challenged to adapt dynamically to maintain the productivity of the organization at satisfactory levels of performance usually impedes these people reflect on the results of their actions and learn from them. Therefore, it is extremely important to create tools that address the methods and techniques of Cognitive Task Analysis (CTA) to assist in the previous training of the security agents, for example, detection and approaches of people who carry radioactive elements. One of the possible ways to accomplish this training is through the use of virtual reality. Virtual environments bring some advantages like reducing costs and risks. The aim of this paper is to present a virtual simulator to evaluate the use in training agents in major events. As a case study, the Maracanã and the agents of the National Nuclear Energy Commission (CNEN) was chosen
