Abstract: The Brazilians educational institutions need a large energy demand for the operation of laundries, restaurants and accommodation of students. Much of that energy comes from steam generated in boilers with wood fuel. The laboral activity in boiler may present problems for the operator’s health due to exposure to excessive heat, and its operation has a high degree of risk. This paper describes an analysis made the conditions of thermal environment in the operation of a B category boiler, located at a Higher Education Institution, located in the Zona da Mata Mineira The equipments used to collect data were Meter WBGT …of the Heat Index; Meter of Wet Bulb Index and Globe Thermometer (WBGT); Politeste Instruments, an anemometer and an Infrared Thermometer. By the application of questionnaires, the second phase consisted of collecting data on environmental factors (temperature natural environment, globe temperature, relative humidity and air velocity). The study concluded that during the period evaluated, the activity had thermal overload. Show more

Abstract: Many authors studied work situations and, mainly, ergonomics projects concerning the financial benefit point of view. At the same time seems to be little information available concerning these financial benefits in manufacturing companies’ processes. The aim of this article is to identify if there enough information available within a company to quantify the financial benefits of an ergonomic project. The study was applied on two manufacturing companies, one in Brazil and other in Portugal. A literature review based checklist and a manager interview was applied on each company in order to identify if the information was available and how were …been used. The two companies have revealed a good quantity of available information regarding ergonomics benefit calculation. The interviews showed that managers are not aware of the financial savings possibility with investments in ergonomics projects. Show more

Abstract: In Human Factors and Ergonomics Science (HFES), it is difficult to identify what is the best approach to tackle the workplace and systems design problems which needs to be solved, and it has been also advocated as transdisciplinary and multidisciplinary the issue of “How to solve the human factors and ergonomics problems that are identified?”. The proposition on this study is to combine the theoretical approach for Sustainability Science, the Taxonomy of the Human Factors and Ergonomics (HFE) discipline and the framework for Evidence-Based Medicine in an attempt to be applied in Human Factors and Ergonomics. Applications of ontologies are …known in the field of medical research and computer science. By scrutinizing the key requirements for the HFES structuring of knowledge, it was designed a reference model, First, it was identified the important requirements for HFES Concept structuring, as regarded by Meister. Second, it was developed an evidence-based ergonomics framework as a reference model composed of six levels based on these requirements. Third, it was devised a mapping tool using linguistic resources to translate human work, systems environment and the complexities inherent to their hierarchical relationships to support future development at Level 2 of the reference model and for meeting the two major challenges for HFES, namely, identifying what problems should be addressed in HFE as an Autonomous Science itself and proposing solutions by integrating concepts and methods applied in HFES for those problems.

Abstract: The purpose of this paper is to present an ergonomic evaluation of a situation of co-exposure to solvents and noise in a flexible packaging printer. We discuss how such an approach carried out in the field of printing industry work has made it possible to highlight serious shortcomings in the effectiveness of the prevention actions that are supposed to protect workers from chemicals risks and noise. The ergonomic analysis identified a strain working conditions. Indeed, some jobs expose to noise and toxic risk. Lamination operations, winding and cutting are purveyors of noise. Some physical and spatial factors contribute to amplify …the toxic risk. The not wearing of personal protective equipment (PPE) by the operators maybe explained by the fact that it doesn’t any possibility to do “otherwise”. Indeed, operators adopt a compromise to achieve the objectives of production to the detriment of their health and safety. These constraints are causing gene and psychosocial factors. The interviews revealed a state of psychosis in the workshop, which was accentuated by the reclassification of an operator which has created a climate of panic and anxiety especially for older operators who have more than 20 years exposed to handling of toxic and more exposure to high noise level.

Abstract: Infrared imaging has been used to visualize superficial temperatures in industrial employers standing and working in an indoor environment at 22°C. Temperature distributions and changes have been recorded digitally and analyzed. Mean skin temperatures determined by this method have been compared with superficial temperatures obtained with a probe thermocouple. During working hours, surface temperatures were higher over extensor muscles than over other structures and their spatial distributions differed dramatically from those observed before working hours. The authors also analyzed the cold water immersion of the hands during work. This paper showed that working generates different thermal effects on human skin …that reflect physiological and pathological occupational conditions and can be monitored by infrared imaging.

Abstract: The Authors make a detailed analysis of the introduction of the OCRA Methodology in Brazil that started in August 2008 with the launching of the “OCRA Book” translated to Portuguese. They evaluate the importance of the assessment of the exposure of the upper limbs to the risk due to repetitive movements and efforts, according to the national and international legislation, demonstrating the interconnection of the OCRA Methodology with the Regulating Norms of the Ministry of Labor and Work (NRs – MTE), especially with the NR-17 and its Application Manual. They discuss the new paradigms of the OCRA Method in relation …to the classic paradigms of the ergonomic knowledge. They indicate the OCRA Method as the tool to be used for the confirmation or not of the New Previdentiary Epidemiologic Nexus NTEP/FAP. The Authors present their conclusions based on the practical results the “participants certified by the OCRA Methodology” achieved in the application on different laboral activities in diverse economic segments, showing the risk reduction and the productivity of the companies.

Abstract: Work-related musculoskeletal disorders (WMSD) are common in computer professionals worldwide. Studies have shown that there is an association between the working posture and the development of musculoskeletal disorders. The IT professionals are exposed to different awkward posture while working. Therefore, it is expected that workers may develop different kinds of musculoskeletal discomfort/pain. This study aimed at to find out the relationship between the musculoskeletal discomfort and the postural score. RULA was used for postural analysis. Results of the postural analysis revealed that 30% of the participant’s posture need to “modify soon” and 15% need to modify “immediately”. 78% of the …participants were using computer for more than 8 hours in a day. The major workstation risk factors were reported as improper keyboard height and mouse tray height (32%), improper monitor height (27%) and improper chair height (12%). Results also revealed a significant association between the regional body pain and the RULA score. Musculoskeletal pain was significantly associated with workstation keyboard/mouse surface (r=0.55) and duration of computer use (r=0.64). Intervention programme was recommended for the participant to modify the workstation and the working posture. Show more

Abstract: Goal - remote online ergonomic assessment in the office environment as compared to face-to-face ergonomic assessment and examination of the applicability of remote online ergonomic assessment to office workers. 40 employees from a large Israeli hi-tech company were ergonomically assessed per the University of California computer usage checklist, according to the two assessment types (face-to-face and remote). An additional Ergonomist “assessor 2” examined the credibility of the process. Results: Research hypothesis 1 was verified: 21 out of 22 questions (95.45%) from the checklist indicated compatibility between “assessor 1” to the “Gold Standard” at an 80% level. Research hypothesis 2: examining …the credibility between the assessors with regard to remote assessment. This hypothesis was partially verified, the correlation between the assessors was measured at 0.54. Research hypothesis 3: examining the extent of deviation of natural posture between distal body parts assessment (distant from the center of the body) and proximal body parts (close to the center of the body). This hypothesis was clearly verified. It has been proven that there is statistical significance between the results. Conclusions: The current research has proved that there is an additional method to assess musculoskeletal disorders risk factors remotely online at office environment. Show more

Abstract: The measurement of performance is a current topic in the management of people in companies, used as a parameter of effectiveness of processes and operations of production. The methods and models of the indicators of current use in the production have concentrated in the assessment of people's performance as determinative resource of the organizational success in the search for the competitiveness. Associated with the classic indicators of performance assessment of the production proceeding, other indicators are used in the assessment of risks and hazards, however with methods focused in the tasks, without connection with the real work activity. The present …article explores literature on the models of performance measurement in use in companies and a field research to understand how companies interpret and use indicators that relate health and work, to direct future studies on the subject. Regarding the literature review, one can see that health indicators can be basically divided into two major groups: the legal and managerial indicators. When conducting case studies, it can be realized that companies do not have precisely the concept of health indicator, or were unable to define which of the indicators could be considered indicators of health, considering that absenteeism was the indicator mentioned by the four companies.

Abstract: This paper presents our reflections on the issue of behavioral change according to energy conservation constraints and on the status of sustainability in the design of ambient interactive systems at home. We point out how ergonomics contributes to the study of human factors underlying energy consumption. Relating to situated cognition and human computer interaction, our approach relies both on the ergonomic evaluation of feedback consumption displays and on the modeling of domestic activities in order to identify household concerns in real settings. We present empirical results to illustrate this global approach. The results of those studies allow the design of …interactive systems: informative and pedagogical systems as well as pervasive and adaptive ambient systems. In our approach, sustainability is taken into account as a design criterion, as security could be, whereas the main design purpose is to aid households in their daily life in order to build a “sustainable situation”.

Abstract: With the advent of the deep economic crisis in Argentina on 2001, the recovery of companies through to the creation of the Cooperatives Working Self-Management or Factories Recovered by its workers was constituted as one of the ways in which the salaried disobeyed the increasing unemployment. When the companies turn into recovered factories they tend to leave of side practices that have been seen like imposed by the previous organization and not understanding them as a primary condition for the execution of his tasks. Safety and ergonomics are two disciplines that are no longer considered relevant to the daily work. …Therefore this investigation aims to revalue, undergo semantic to give back to a place in every organization analyzed. This research developed a self-diagnostic tool for working conditions, and the environment, present in the recovered factories. Show more

Abstract: The development of ergonomics’ recommendations, guidelines and standards are attempts to promote the integration of ergonomics into industrial contexts. Such developments result from several sources and professionals and represent the effort that has been done to develop healthier and safer work environments. However, the availability of large amount of data and documents regarding ergonomics does not guarantee their applicability. The main goal of this paper is to use a specific case to demonstrate how ergonomics criteria were developed in order to contribute to the design of workplaces. Based on the obtained results from research undertaken in a tire company, it …was observed that the ergonomics criteria should be presented as design specifications in order to be used by engineers and designers. In conclusion, it is observed that the multiple constraint environment impeded the appliance of the ergonomics criteria. It was also observed that the knowledge on technical design and the acquaintance with ergonomic standards, the level of integration in the design team, and the ability to communicate with workers and other technical staff have paramount importance in integrating ergonomics criteria into the design process.

Abstract: As demanded at Collective Employment Agreement (CEA), three Ergonomic assessment of work (AEW) where made into an airport from a big Brazilian city (in particular, at the flight tower), with a 2 years interval between them. The objective was to produce a report pointing out problems and solutions. At the third time (2010), were verified that the work conditions where almost the same from 2006 and 2008, although all recommendations made in the reports. This work presents how the AET Team worked with this situation. At the third AEW, due the lack of real changes and the necessity of a …report, the strategy was to know how workers where dealing with the complains and constraint detected at the previous reports, and how it interfere in abnormal or danger situations. Trying to explain this organizational phenomenon, we resort to Resilience Engineering to understand how those f/actors played to achieve its objectives. Show more

Abstract: Malnutrition is a major problem for rural areas of Sub-Saharan Africa. Technology such as the maize mill, which alleviates the burden of pounding grain, also introduces opportunities and new challenges for improved nutrition. While there have been many technical studies of grain mills, and maize mills are in operation in hundreds of locations throughout Sub- Saharan Africa, the maize mill has not been studied from a socio-technical system perspective. This paper reports on the first phase of a study grounded on the hypothesis that mills can improve nutrition by exploiting their function as a social gathering point and providing both …instruction and enjoyable healthful products. The objective was to identify those products that could be made available that customers at the mill would be willing to buy. Following observation of food availability, preparation, and consumption preferences within daily work routines, sample products were prepared and presented for cooking and consumption, along with some discussion at a district center mill owned by a local woman. The responses of customers and the mill owner were positive. Strategies for local manufacture and distribution of these products for sale and roles of the mill owner and the mothers are questions for future study. Show more

In Spain there are experiences since 1995 and an important development and this paper is to investigate the actions required for a more widespread use in trials. Consensus methods such as the Delphi survey technique are being employed to help enhance effective decision-making in the future development of Ergonomics Forensics. The Delphi survey is a group …facilitation technique, which is an iterative multistage process, designed to transform opinion into group consensus. It is a flexible approach, that is used commonly within the health and social sciences, however, there is little use and practice of ergonomics as a technique to facilitate the participation of all experts involved: judges, lawyers and expert ergonomists Show more

Abstract: The growing need in Algeria to develop ergonomics knowledge and practice in industry was behind the initiative to develop a training and research project within the ergonomics laboratory at Oran University. Since 2005 the laboratory team is running an academic option master in work design and ergonomics. The evaluation of the academic master in 2010 revealed the acute need of the local industry for professional competences in ergonomic and work psychology. A professional training master program in “ergonomics & work psychology” was then developed in partnership with local industry, five European Universities and six Universities from three Maghreb countries. Research …projects were initiated around the two training programs, in conjunction with a number of ergonomics dissemination and promotion activities. Preliminary results of the project are presented and discussed in relation to the local context, and in the light of similar cases in Industrially Developing Countries. Show more

Abstract: During the last five years, several research review studies have revealed insufficient or even no proof that courses in manual material handling (MMH) are effective at preventing musculoskeletal disorders (MSD). These revelations are placing the current daily practice of MMH trainers under scrutiny. This study analyses how the MMH courses are organised in practice. A web-based questionnaire was developed for trainers. Only trainers giving MMH courses on a regular basis were included. The questionnaire focussed on general characteristics of the courses, content issues and organisational aspects. The results clearly indicated that the MMH courses can only be considered as a …means of making employees aware of good manual handling. Not all content issues that should be addressed in effective MMH courses, are looked at in practice. This is mainly due to time restrictions that trainers experience, often imposed by the company. In conclusion, these organisational restrictions might explain the ineffectiveness of the MMH courses and should therefore be resolved. Show more

Abstract: The present study was developed based on the analysis of workplaces in the engineering industry, particularly in automotive companies. The main objectives of the study were to evaluate the activities present in the workplace concerning manual handling, using assessment methodologies NIOSH Ergonomic Equation [1] and Manual Material Handling [2], present in ISO 11228 [3-4], and to consider the possibility of developing musculoskeletal injuries associated with these activities, an issue of great concern in all industrial sectors. Similarly, it was also shown the suitability of each method to the task concerned. The study was conducted in three steps. The first step …was to collect images and information about the target tasks. As a second step proceeded to the analysis, determining the method to use and to evaluate activities. Finally, we found the results obtained and acted on accordingly. With the study observed situations considered urgent action, according to the methodologies used, and proceeded to develop solutions in order to solve the problems identified, eliminating and / or minimizing embarrassing situations and harmful to employees.

Abstract: The Brazilian commercial aviation industry has grown strongly in the last decades, increasing passenger capacity and operational safety. While several studies focus on flight safety and passenger comfort, few are dedicated to the manual transport of loads. Although apparently this sector has low relevance, every year nearly 9% of their workers are injured. It is estimated that these injuries cost more than 10 million dollars a year to the companies involved. This study assesses quantitatively the risk of injury on employees. NIOSH method was used to evaluated the possibility of injury in different tasks. Factors such as the pace of …activity, horizontal and vertical displacement, and asymmetries were evaluated during loading and unloading of luggage. This study showed that the frequency of repetitions of loading was excessive in all cases analyzed. However, the use of conveyors reduced the risk of employee injury, reducing this possibility to acceptable levels. The study shows that simple measures can help reduce the number of injuries and hence the cost that this entails. Show more

Abstract: The goal of this study was to use a pressure sensor to measure the force distribution and contact area of the hand when gripping, pushing, and pulling a cylinder. Data was collected from 10 subjects with no hand impairments and from 1 subject with rheumatoid arthritis (RA). Subjects grasped an aluminum cylinder wrapped with a Tekscan pressure sensor and performed each trial at 25%, 50%, and 100% maximum voluntary exertion. A relationship was found between increasing exertion and increasing hand area with increasing hand contact area. The force distribution maps showed the thenar region of the hand exerts the most …force during pushing while the metacarpal joint line exerts the highest force during pulling. The third and fourth phalange were found to exert the highest phalange force during gripping. The force distribution maps from the RA subject showed higher thumb forces and distal phalange forces, relative to the entire phalange, compared to the non-impaired subjects. This suggests that the RA subject compensates for the lack of phalange function with the regions of the hand that still function. Future studies should sample individuals with a larger hand area range and sample more individuals with RA. Show more

Abstract: Conducting field research facilitates understanding human daily activities. Cognitive Chrono-Ethnography (CCE) is a study methodology used to understand how people select actions in daily life by conducting ethnographical field research. CCE consists of measuring monitors’ daily activities in a specified field and in-depth interviews using the recorded videos afterward. However, privacy issues may arise when conducting standard CCE with video recordings in a daily field. To resolve these issues, we developed a new study methodology, CCE Lite. To replace video recordings, we created pseudo-first-personview (PFPV) movies using a computer-graphic technique. The PFPV movies were used to remind the monitors of …their activities. These movies replicated monitors’ activities (e.g., locomotion and change in physical direction), with no human images and voices. We applied CCE Lite in a case study that involved female employees of hotels at a spa resort. In-depth interviews while showing the PFPV movies determined service schema of the employees (i.e., hospitality). Results indicated that using PFPV movies helped the employees to remember and reconstruct the situation of recorded activities. Show more

Abstract: The Ergonomic tridimensional Analysis (ETdA) was developed to be used as an auxiliary tool on the ergonomic intervention. It was specially designed for commercial areas with free circulation of people. Due to that, the client, the third ETdA dimension, becomes an important element and their opinions relevant in the ergonomic analysis. The remains two ETdA dimensions, professionals and analyst, play an identical role as in the traditional occupational ergonomic analysis. For each of these dimensions, specific observation tools were assembled: an ETdA questionnaire, an evaluation form and a checklist for direct and indirect observations. The variables that allow the ETdA …operability are identified as Ergonomic Factors (EFs). A case study is presented identifying, for each dimension, the critical EFs. This will allow the design of the weighting table, where the influence of each dimensions results is measured, stressing the important role of clients on ergonomic issues. Show more

Abstract: Checkout cashier work consists of handling a large number of items during a work shift, which implies repetitive movements of the shoulders, arms and hands/wrists, and a high work rate. The work is associated with a high prevalence of disorders in the neck and upper extremity. The concept of workstyle explains how ergonomic and psychosocial factors interact in the development of work-related upper extremity disorders. The aim of the project was to develop an instrument for the occupational health services to be used in the efforts to prevent upper extremity disorders in checkout cashier work. The instrument is based on …the workstyle concept and is intended to be used as a tool to identify high-risk workstyle and needs for interventions, such as training and education. The instrument, BAsIK, consists of four parts; a questionnaire about workstyle, an observation protocol for work technique, a checklist about the design of the checkout and a questionnaire about work organization. The instrument was developed by selecting workstyle items developed for office work and adapting them to checkout cashier work, discussions with researchers and ergonomists, focus-group interviews with cashiers, observations of video recordings of cashiers, and studies of existing guidelines and checklists.

Abstract: Typing is associated with musculoskeletal complaints (MSCs), caused by multiple risk factors. Although a wide variety of ergonomic intervention programs were conducted to reduce risk factors and MSC’s, only few of them were found evidence based. This study aimed to test the efficacy of a workplace intervention in reducing MSC’s among computer workers. 66 computer workers were assigned randomly to one of three intervention programs: ergonomic intervention including biofeedback, intervention without biofeedback and control group without intervention. The efficacy was tested by advanced assessment including; pain location and severity, posture at work, upper extremity 3D kinematics, muscle activity and psychosocial …status. Working hypothesis; significant score differences will be found between the study groups which underwent ergonomic intervention and the control group on the following measures: pain complaints, upper extremity kinematics, muscle activity and psychosocial status. Significant differences were found between pre and post intervention and between research groups and the control group in pain, posture and motion. The ergonomic intervention with biofeedback had no unique contribution in comparison to other interventions. In conclusion; the proposed intervention program was found efficient for reducing pain among computer workers. Show more

Abstract: Generally, the studies assess the upper limbs postures during the work with Visual Display Terminal – VDT through the measurement of the angles formed by the segments or through the relation with the pre-defined anatomical postures (e.g., flexion, extension, abduction). However, few studies were found in the literature which had focused in the measurement of the upper limbs support during a real situation of work with VDT and in the definition of analysis categories for this kind of behavior. The main objective of this study was to measure, in a real situation and using a systematic observation method through video …analysis, the main kinds of support for the upper limbs. The analysis was done considering 480 work hours of 30 office workers. Data were collected using a methodology proposed by Rebelo, Filgueiras & Soares [1] and related with the work organization and workspace conditions, the participants had: a) minimum of eight hours daily of work; b) similar activities, characterized as office work; c) same furniture and equipment; and, d) computers with the same hardware, software and peripherals. Results were analyzed 46554 dynamic events, considering only the fourteen Interaction Categories – ICs, for upper limps support. In this way, percentage was computed, considering the total number of occurrence, for the Right arm is: arm support (0.06%); forearm support (31,8%); elbow support (31,92%); hand support (7,41%); multiple supports (12,32%) and without support 16,41%- For the Left arm the results is: forearm support (0,11%); arm support (53,69%); elbow support (8,70%); hand support (7,97%); multiple supports (8,43%) e without support (21,11%). This systemic and ecological approach was obtained through a method which enables experimental Biomechanics and Physiology methods to develop more efficient functional requirements and recommendations for the work with VDTs.

Abstract: The current article presents the process of situated modeling in the drawing workshop for bobbin lace developed and implemented in the Núcleo de Produção Artesanal Rendeiras da Vila, in Ponta Negra, Natal-Brasil. The workshop aimed to rescue the domain over the product in the production of bobbin lace through capacitation of both experienced and novice craftswomen. The modeling of the drawing workshop was grounded on the sociotechnical construction and in the concepts of anthropotechnology and also social technology. The modelling required an intense process of social construction involving the members of GREPE-UFRN (Group of extension and Research in Ergonomics) and …the lacemakers od the community. The domain of drawing the lace has enabled the expression of the craftswomen creativity, increasing the amount of works and the sustainable development,thus reducing the risks of extinction of such art in the Village of Ponta Negra.

Abstract: This paper presents the Ergonomic Work Analysis method in a Brazilian Dentist’s office. Through the study, the constraints and the strategies in avoiding them were identified. It was found that dentists hardly use the position most indicated by the International Organization for Standardization (ISO) and the Federation Dentaire Internacionale (FDI) for both the patient and the dentist, which is respectively supine and 9 o’clock, due to the limited space and layout. Five types of treatments performed by the professional have been studied. The frequency and duration of actions in these treatments were accounted for and the standard positions adopted were …identified. The AET was found to be a very suitable method to grasp the dentist’s activity and build a point of view of the profession, which is characterized as: stressful, perfectionist and restrictive. Time management is presented as an important strategy to control the tension arising from performing the treatments. Show more

Abstract: The internationalization of labor is a prominent feature of the economy today, but is accompanied by adverse effects on operator health. In general, musculoskeletal diseases are the first to appear in this context. The open observations activity and interviews with operators and the hierarchy have been made to discover the organizational constraints. Other interviews were also conducted to account for the determinants of activity outside of work. The use of video has allowed the registration of work cycles, which helped to describe and quantify the postures and gestures to establish a possible link between musculoskeletal diseases and work activity. The …collected data were processed using software Actogram Kronos. To understand the process of origin of these diseases, the analysis of the socioeconomic context is also essential because they in part determine the organization of certain companies. The objective of this paper was to discuss the activities of operators of blistering in both work and outside work. The goal is to determine the constraints presents in these two spheres of activity, that may increase the risk of developing musculoskeletal diseases and to define their interaction. Show more

Abstract: The incidence of workers suffering from occupational injuries has alerted health professionals and entrepreneurs. Enterprises are looking for improvements in production systems by investments in quality, technological innovations and in human resources that are capable and committed to the objectives and targets of the enterprise. This research was developed in a pig slaughter-house in the city of Ipiranga-SC, in the labor of boning shoulder of the pig, because this is the activity that presents more registers of complaints of pain and also probability of development of occupational diseases with cause in the enterprise.Tools of Ergonomics Analysis of Work were used, …from interviews with workers to the application of LEST method in the activity analyzed. The necessity of immediate intervention in the work station was shown in the results, because of the high risk of prejudice to the health of the workers. Improvement actions must be done to satisfy the ergonomics requirements of NR 17 standard, attending the enterprise interests in the occupational diseases prevention. Show more

Abstract: The objective was to analyze the work activity and identify risk factors that could account for musculoskeletal disorders in the upper extremities, shoulder and neck of workers of a transport values company in Venezuela. The methods used were: collective interview, tasks observation, evaluation of posture with RULA method and evaluation of repetitive motions with the OCRA method. Five workstations were evaluated. Main problem perceived by workers was: exposure to chemical and biological hazards when handling paper money and coins; inadequate chairs and close supervision. The postures level risk was 1 or 2 for the RULA scale. Only two workstations showed …ligth and medium risk level by OCRA method. Conclusion: The factors identified that could explain the musculoskeletal changes were: wrist repetitive flexion and extension, shoulder elevation, lifting weight above shoulder height, elbow repetitive flexion and extension, neck flexion, extended work journey, work overload, high responsibility and strict supervision by a video camera.

Abstract: Currently, there is a trend in nuclear power plants (NPPs) toward introducing digital and computer technologies into main control rooms (MCRs). Safe generation of electric power in NPPs requires reliable performance of cognitive tasks such as fault detection, diagnosis, and response planning. The digitalization of MCRs has dramatically changed the whole operating environment, and the ways operators interact with the plant systems. If the design and implementation of the digital technology is incompatible with operators’ cognitive characteristics, it may have negative effects on operators’ cognitive reliability. Firstly, on the basis of three essential prerequisites for successful cognitive tasks, a causal …model is constructed to reveal the typical human performance issues arising from digitalization. The cognitive mechanisms which they impact cognitive reliability are analyzed in detail. Then, Bayesian inference is used to quantify and prioritize the influences of these factors. It suggests that interface management and unbalanced workload distribution have more significant impacts on operators’ cognitive reliability. Show more

Abstract: The aim of this paper is to highlight how ergonomics contributes to risk analysis and risk management in a design project for a new reactor, the French EPR (European Pressurized Reactor). An iterative ergonomics design process has been conducted over the last 10 years through a Human Factors Engineering program at the French energy company EDF. A parallel has been drawn between a risk management process and this ergonomics process based on International Organization for Standardization (ISO) publications such as ISO/IEC Guide 73, ISO Guide 51, etc. The contribution of ergonomics to risk analysis is illustrated by an example: the …automatic diagnosis, which is a very important technical device for safety. Five main types of risk have been identified via ergonomic analyses during the different design stages. Counter-measures have been implemented and their efficacy tested within the scope of new campaigns to assess human factors. However, the management of risks in such a design project requires the participation both of the different design entities involved in the project and of other experts in aspects of risk management, such as human reliability. The organization of collaborative participation remains a challenge to be addressed. Show more

Abstract: It is widely recognised that ergonomists must contribute during needs analysis. However, few studies have investigated the specific contributions of ergonomists at this stage of the design process. In this study, this contribution is studied through the requirement document produced by the design team. For each requirement, the source (i.e. who formulated the requirement), justification (why the requirement is needed), type (functional, interaction, operational, physical, organizational), and scope (entire system or part thereof) were analysed. Results indicate that the various actors are complementary and work collectively to define the various dimensions of the system. With end-users, the ergonomist worked on …the global aspects of the system: function, conditions of use and organizational dimension. Alone, he defined the global interaction of the system. The various functions derived from the global function were defined in collaboration with engineers. However, while engineers contributed to defining how these functions would work, as well as their technical conditions of use, the ergonomist focused on their purpose, and, with end-users, on their organizational aspects. Finally, results suggest that neither the ergonomist’s specific knowledge in ergonomics, nor work analysis were sufficient to derive his requirements; both are mandatory. Show more

Abstract: This study presents the challenge involved in the negotiation and construction of a standard process in a major petroleum company that has the purpose of guiding the implementation of ergonomic studies in the development of projects, systemising the implementation of ergonomics design. The standard was created by a multi-disciplinary working group consisting of specialists in ergonomics, who work in a number of different areas of the company. The objective was to guide “how to” undertake ergonomics in all projects, taking into consideration the development of the ergonomic appraisals of work. It also established that all the process, in each project …phase, should be accompanied by a specialist in ergonomics. This process as an innovation in the conception of projects in this company, signals a change of culture, and, for this reason requires broad dissemination throughout the several company leadership levels, and training of professionals in projects of ergonomics design. An implementation plan was also prepared and approved by the corporate governance, complementing the proposed challenge. In this way, this major oil company will implement new procedures of ergonomics design to promote health, safety, and wellbeing of the workforce, besides improving the performance and reliability of its systems and processes.

Abstract: Oil and Gas Exploration and Production activities are carried out in hazardous environments in many parts of the world. Recent events in the Gulf of Mexico highlight those risks and underline the importance of considering human factors during facility design. Ergonomic factors such as machinery design, facility and accommodation layout and the organization of work activities have been systematically considered over the past twenty years on a limited number of offshore facility design projects to a) minimize the occupational risks to personnel, b) support operations and maintenance tasks and c) improve personnel wellbeing. During this period, several regulators and industry …bodies such as the American Bureau of Shipping (ABS), the American Society of Testing and Materials (ASTM), the UK’s Health and Safety Executive (HSE), Oil and Gas Producers (OGP), and Norway’s Petroleum Safety Authority (PSA) have developed specific HFE design standards and guidance documents for the application of Human Factors Engineering (HFE) to the design and operation of Oil and Gas projects. However, despite the existence of these guidance and recommended design practise documents, and documented proof of their value in enhancing crew safety and efficiency, HFE is still not well understood across the industry and application across projects is inconsistent. This paper summarizes the key Oil and Gas industry bodies’ HFE guidance documents, identifies recurring themes and current trends in the use of these standards, provides examples of where and how these HFE standards have been used on past major offshore facility design projects, and suggests criteria for selecting the appropriate HFE strategy and tasks for future major oil and gas projects. It also provides a short history of the application of HFE to the offshore industry, beginning with the use of ASTM F 1166 to a major operator’s Deepwater Gulf of Mexico facility in 1990 and the application of HFE to diverse world regions. This latter point highlights the need to consider user populations when selecting HFE design criteria, an aspect strongly emphasized in current industry guidance. Show more

Abstract: This paper aims to discuss the role of ergonomics in design process using the dialogue developed by designers, implementers and users in an oil refinery. It was possible to identify the need of minimizing the postural constraints, risk of accidents, mechanical shocks and to enlarge safety perception in the access and permanency of the users at the workspace. It has been determined and validated by workers and managers to implement different deadlines depending on programming, viability and execution time for the improvements proposed. In a long-term: it was proposed the substitution of the ladders with time planning according to the …maintenance program of the tanks; in a short-time: it was suggested the expansion of the existing platforms, implementation of a walkway connection provided with guardrails between the upper access of the side ladder and the repositioning of radar set and aerial aiming at the usage by workers at the workstation of the new platform. It was also elaborated eight typologies of intervention, according to the request, type of tank, material stored, and its setting place. The design process arises from ergonomics workplace analysis that presents concepts for solutions which was a mediator tool to be settled between users and implementers. Show more

Abstract: Ergonomic Design is the adaptation of working conditions to human limitations and skills in the physical design phase of a new installation, a new working system, or new products or tools. Based on this concept, the purpose of this work was to analyze the implementation of ergonomic design at the new industrial units of an oil refinery, using the method of Ergonomic Workplace Assessment. This study was conducted by a multidisciplinary team composed of operation, maintenance and industrial safety technicians, ergonomists, designers and engineers. The analysis involved 6 production units, 1 industrial wastewater treatment unit, and 3 utilities units, all …in the design detailing phase, for which 455 ergonomic requirements were identified. An analysis and characterization of the requirements identified for 5 of the production units, involving a total of 246 items, indicated that 62% were related to difficult access and blockage operations, while 15% were related to difficulties in the circulation of employees inside the units. Based on these data, it was found that the ergonomic requirements identified in the design detailing phase of an industrial unit involve physical ergonomics, and that it is very difficult to identify requirements related to organizational or cognitive ergonomics.

Abstract: Ergonomics is the study of a workplace and the worker. Its aim is to better adapt the workplace to man by preserving the body for short and long term work. This helps to adjust and improve functionality, thus preserving the body for short and long term work. It was through the observation of SAMU's (Mobile Emergency Unit) professional's helpers that the interest to evaluate these individuals arose. In addition, the aim of this research is to investigate the work ability of health professionals that work for SAMU/JP. The population was composed of 97 health professionals who currently work for SAMU/JP. …A sociodemographic questionnaire was used as data collection instrument and it was validated by the index of the Work Ability (WAI). The research took place in 2010, in the headquarters of SAMU, in the city of João Pessoa, state of Paraíba – Brazil. The data analysis was carried out by simple descriptive statistics followed by comparison of the results with the pertinent literature. The quantity of daily sleeping hours, the levels of satisfaction in the job and the number of diagnosed diseases were among the most worrying factors. In spite of this, the health professionals obtained a work ability average considered to be “good”. Show more

Abstract: This communication deals with the involvement of ergonomists in a research-action design process of a software platform in radiotherapy. The goal of the design project is to enhance patient safety by designing a workflow software that supports cooperation between professionals producing treatment in radiotherapy. The general framework of our approach is the ergonomics management of a design process, which is based in activity analysis and grounded in participatory design. Two fields are concerned by the present action: a design environment which is a participatory design process that involves software designers, caregivers as future users and ergonomists; and a reference real …work setting in radiotherapy. Observations, semi-structured interviews and participatory workshops allow the characterization of activity in radiotherapy dealing with uses of cooperative tools, sources of variability and non-ruled strategies to manage the variability of the situations. This production of knowledge about work searches to enhance the articulation between technocentric and anthropocentric approaches, and helps in clarifying design requirements. An issue of this research-action is to develop a framework to define the parameters of the workflow tool, and the conditions of its deployment. Show more
