Avaliação da gravidade do trauma em condutores de motocicleta vítimas de acidentes de trânsito no Rio Grande do Norte

Descriptive exploratory study, prospective, with quantitative approach, performed on the Monsenhor Walfredo Gurgel Hospital Complex (MWGHC), in Natal/RN, aiming to identify injuries by body area and wound severity on drivers who suffered motorcycle accidents, evaluate the severity of injuries and trauma on these drivers and identify the existence of association between wound and trauma severity and some of the accident s characteristics. The population comprised 371 motorcycle drivers, with data collected between October and December 2007. We used as instruments the Abberviated Injury Scale (AIS), Injury Severity Score (ISS) and the Glasgow Coma Scale (GCE1). The results show that, concerning characterization, there was a predominance of the male gender (88.4%), aged between 18 and 24 years (39.90%), originating from the Natal metropolitan region (55.79%), with fundamental-level instruction (51.48%), catholic (75.78%), married (47.98%). 23.18% work on commerce-related activities and 75.20% have income of up to 2 minimum wages. As for the accident s characteristics, the predominant shift was the afternoon (46.36%), received up to one hour after the event (50.67%), transported by countryside ambulances colleagues and relatives (51.21%), 25.34% had the accident on Sunday; 53.91% suffered falls and vehicle rolls; among the collisions there was a predominance of the motorcycle-automoblie type (28.03%); 52,6% were licensed and among these 50.76% had up to one year of license; 65.50% declared not having suffered previous accidents; 65.77% declared waring helmets in the time of the accident; 57.41% said not to have used drugs, and among those who used, alcohol was the most consumed (98.10%). The lowest score evaluated by GCS1 (3 to 8) was linked to drivers who suffered accidents on Saturday (10.3%), those who were not wearing helmets (14.29%) and the victims of motorcycle-pedestrian/animal crashes (13.33%). The body areas most affected had AIS between 1 and 3 (95.76%) and were: external surface (39.90%) and head/neck (33.20%). As for trauma severity, the highest scores (ISS>25) belonged to those who consumed alcohol (30.73%), suffered falls or vehicle rolls (48.9%) and those attended to 3 hours or longer after the accident (50%). We conclude that for motorcycle drivers who suffered accidents, age, gender, weekday, type of accident, use of drugs and the absence of helmet use signal both to the risk of occurrence of these events, as well as for the greater severity of injuries and trauma.

Caracterização do acidente de trânsito e gravidade do trauma: um estudo em vítimas de um hospital de emergência de Natal

Descriptive exploratory study, with quantitative approach and prospective data performed on the Monsenhor Walfredo Gurgel Hospital Complex (MWGH), in Natal/RN, aiming to classify the type of motor vehicle involved in the accident, the public roadway s user quality and the more frequent injuries; to evaluate the severity of trauma in traffic accident victims; characterized the severity of the injuries and the trauma, and the type of motor vehicle involved. The population comprises 605 traffic accident victims, with data collected between October and December 2007. We used as a support for the evaluation of severity of injuries and trauma the Glasgow Coma Scale (GCSl), the Condensed Abbreviated Injury Scale (CAIS) and the Injury Severity Score (ISS). The results show that 82.8% of the victims were male; 78.4% were aged 18 to 38; the victims originating from the State s Countryside prevailed (43.1%); 24.3% of the population had completed middle-level instruction; 23.1% worked on commerce and auxiliary activities; most (79.4%) was catholic; 48.8% were married/consensual union; 76.2% earned up to two monthly minimum wages; Sunday was the day with the most accidents (25.1%); 47.4% were attended to in under an hour after the event; the motorcycle on its own was responsible for 53.2% of the accidents; 42.3% were attended to by the SAMU; 61.8% were victims of crashes; over half (53.4%) used individual protection equipment (IPE); 49.4% were helmets and 4.0% the seatbelt; 61.3% were motorcycle drivers; 43.3% of the accidents took place in the afternoon shift; from 395 drivers, 55.2% were licensed, and 50.7% among those had been licensed for 1 to 5 years; 90.7% of the victims had GCS1 between 13 and 15 points at the time of evaluation; the body area most affected was the external surface (35.9%); 38.8% of the injuries were light or moderate (AIS=1 and AIS=2); 83.2% had light trauma (ISS between 1 and 15 points). In face of the results, we can conclude that there is a risk for the elevation of injury severity and trauma resulting from traffic accidents, when these events are related to certain variables such as gender, age, weekday, the interval between the accident and the first care, ingestion of drugs, type of accident, the public roadway s user quality, the use of IPE, day shift, body regions and the type of motor vehicle involved in the accident

Acidentes de Trabalho : análise em profissionais de enfermagem que atuam nas unidades de terapia intensiva e urgência Natal/RN

It is a descriptive-exploratory research, with a quantitative approach, aiming to characterize typical occupational accident suffered by the professionals from nursery group, in the Intensive Care Units and Emergency in a hospital in Natal-RN, trying to identify the factors that contribute to those accidents; to identify some information taken by those professionals related to the accident risks; to know the procedures taken after each accident. This sample is composed by 176 professionals that are 44 nurses and 132 nursing technicians/auxiliaries, collected from March to April 2010. The results related to the personal characterization of the nursery group showed that 31 (18.61%) are between the 36-40 years of age; 148 (84.09%) females and 96 (55.68%) had finished High School. Related to the professional characterization, 53 (30.11%) are nurses, and 123 (69.88%) nursing technicians and auxiliaries; 44 (25.00%) are working as nurses, and 132 (75.00%) as nursing technicians and auxiliaries; 45 (25.56%) are working in the nursery area between 15 to 20 years and 11 months; 53 (30.11%) are in this institution between 10 to 14 years and 11 months; 79 (44.88%) work in the ICU; 55 (31.25%) are working in this area from 1 to 4 years and 11 months; 110 (62.50%) like to work in this area; 161 (91.47%) work 30 to 40 hours per week; 90 (51,13%) have another employment. Related to knowledge about typical occupational accident, 167 (94.88%) said they know about it; 96 (54.54%) know the accident rules; 103 (58.52%) think it is important to talk about this subject in the nursery courses; 92 (52.27%) said this subject is important to be discussed in the work and 372 (87.73%) think education is necessary to reduce accident. Related to the data about accidents, 104 (59.09%) have suffered typical occupational accident, among them 69 (39.20%) have suffered it once; 47 (36.19%) did not register any accident; 60 (57.69%) were caring some patient during the accident; 47 (45.19%) of them occurred in the ICU; 50 (48.07%) professionals were working during the night period; 69 (66.34%) have suffered perforation; 86 (82.69%) had upper limbs affected; 64 (61.53%) were affected by needle; about the reason of the accident, 89 (60.54%) said it occurred due to carelessness. Related to the accident evolution, 88 (85.57%) did not need to remain off work after accident; 13 (81.25%) remained off work during 15 days; 87 (83.65%) had no sequelae and for 101 (97.11%) it was not necessary rehabilitation. We conclude that typical occupational accident can occur with young workers who admit a knowledge about the subject, however they do almost nothing to prevent it. We believe this research has contributed to the characterization of this kind of accident suffered by the nursery group of a public hospital in Natal, and it can stimulate the creation and reformulation of personal protection against typical occupational accident suffered by nursery professionals

Identificação de crianças e adolescentes com suspeita de câncer: uma proposta de intervenção

Unlike adult cancer, where cells usually originate from epithelial tissue and is linked to environmental factors, malignant tumors in childhood are mostly of embryonic origin and have a phase of rapid proliferation. When not started chemotherapy at this stage, the tumor increases in size, reducing their growth rate, thus reducing the response to chemotherapy. Childhood cancer is in Brazil, the second cause of mortality among children and adolescents from one to nineteen. His impact on the ranking of diseases becomes significantly important to public health since the first issue is related to accidents and violence. Many children are still sent to the centers of high complexity for cancer treatment with advanced stage disease. The delay in referral to diagnosis can be family, or the difficulty of access to the health sector, or the characteristics of the disease and lack of health staff regarding theme of childhood cancer. Before this problem, we aimed to assess the performance of health teams in the identification of child and adolescent symptoms of cancer in primary care, through the action research methodology, which includes the teaching-learning, seminars, describing the actions of the group and discussing the activities after the training. This study involved thirty-seven health professionals who provide care for children and adolescents in the USF Felipe Shrimp II, the Support Center for Children with Cancer and the pediatric hospital UFRN during the period from March to December 2010. The data were analyzed simultaneously to evaluate actions, following the direction of the analysis of ideas Freires, having as theoretical reference the primary health care. The diagnosis of current reality, as knowledge of the health team targeted for early identification of signs and symptoms raised through questioning, presented as generative themes: resistance to change, awareness of the need for apprehension of knowledge; prior knowledge through the media, fragmentation of the healthcare network, interfering with the operation of the reference and counter, the stigma of death, among others. The selected themes enabled the choice of content for the preparation of four seminars, such as implementation of collective action for discussion problematical. The teaching-learning process has allowed the study participants awareness of the problem and work through the knowledge acquired by interfering in decreasing the time interval between the identification of signs and symptoms of cancer and early specialist treatment. Their difficulties we are faced with a diagnosis of terminal cancer and associated with delayed access to laboratory tests and imaging necessary for the diagnosis of neoplasms. Thus, we find that when the team is consciously involved in the education process from identification of the problem situation, there may be significant changes in daily activities through awareness of being. However, we also realize that acquisition of knowledge and interest of the team are not enough, since to be efficiency of our service, we need an organization of cancer care network operating in the state of Rio Grande do Norte

Riscos ocupacionais e acidentes de trabalho em um serviço de atendimento móvel de urgência do Rio Grande do Norte

Exploratory, descriptive and quantitative study with prospective data, performed in the Mobile Emergency Care Service in the metropolitan region of Natal/RN, in order to identify the knowledge of the multidisciplinary team about the rules of standard precautions and worker safety, to identify occupational hazards peculiar to the activities of this service; characterize work-related accidents (WRA) and know the procedures adopted after each WRA. The population consisted of 162 professionals and data were collected between the months of November and December 2010.

As for knowledge of rules of standard precautions, safety and occupational hazards, 99,38% knew what it was WRA; 62,96% gave incomplete answers; 74,07% knew the rules of prevent WRA; 46,67% acquired this knowledge in lectures; 53,09% knew Personal Protective Equipment (PPE); 71,60% gave incorrect answers about the importance of standard precautions; 45,06% never received an educational intervention on this issue; 89,51% said that educational interventions in the prevention of WRA are very important; 90,12% pointed out this as a very important issue in the workplace; 27,00% suggested guidance on the topic in the workplace; regarding the physical hazards, 34,57% considered noise as the most important; about chemical hazards, 78,40% chose the gases and smoke; for biological hazards, 48,77% reported contact with the blood; for mechanical hazards, 80,86% said that were transport accidents; about ergonomic risks, 40,12% say it is the tension/stress in the care of critically ill, psychiatric and aggressive patients; and there was an average of 4,5 to the feeling of safety in the workplace. Regarding the data on the WRAs occurred, 31,48% experienced at least one accident event; 72,55% did not notify it; 60,98% answered that there was no routine for notification; 56,86% were performing patient transportation; 49,02% were hurt in the Basic Support Unit/Rescue Unit (BSU/RH); 60,78% occurred during the day; 96,08% of professionals were in normal work schedule (24 hours on duty); 31,37% had contusion; 58.82% had damage to members/pelvic girdle; 43,14% had traffic accidents. About the evolution of the WRA, 62,75% did not have to take time away from work; 76,47% had no sequelae; 88,24% did not require rehabilitation; no professional had a change of occupation. And by means of univariate logistic regression, showed that the nurses and male sex were risk factors for the occurrence of WRA. We conclude that there were gaps in the knowledge of staff regarding WRA, emphasizing the need for continuing education in biosafety in the service.

Em busca do conhecimento da equipe de enfermagem na sua prática assistencial às vítimas de traumatismo raquimedular

The great demand of accidents resulting in victims with rachi-medullar traumatism (RMT) and the need for indetifying how they are being assisted, led us to proceed with this investigation. It had as its goal to identify and analyze the knowledge of nurses and nurse assistents regarding the nursing assistance to these patients. It consists of a descriptive exploratory study, with a quantitative method and prospective data. For its execution, 193 subjects were interviewed, 37 of them nurses and 157 nurse assistents in 02 hospitals of the metropolitan zone of Natal. The results reveal that the subjects are not coherent when questioned whether they are prepared to assist victim of RMT and the content described by order of piority regarding the steps followed in the assistance of these victims, both in the pre-hospital and hospital care. Thus, we observe that only 06 nurses and 07 assistents, described correctly all the steps necessary to pre-hospital care and only 01 nurse and 02 assistents registered all the steps in the correct sequence regarding the hospital care. We conclude that, in face of the obtained results, we can urgently modify this reality, improving the nursing staff and giving them better work conditions

Trauma em idosos atendidos pelo serviço pré-hospitalar móvel

O The aim of this study was to characterize the occurrence of trauma in the elderly population served by the mobile pre-hospital service, in Natal, Rio Grande do Norte. This is a descriptive, transversal and quantitative approach and whose population consisted of 2,080 trauma victims. The sample, of systematic random type, consisted of 400 elderly people, aged from 60 years old, assisted by the Office of Mobile Emergency in Natal / RN, between January 2011 and December 2012. Data collection began after consent and assent of the institution of a Research Ethics Committee under No. 309 505. It was proceeded to documentary retrospective analysis of records of this service through a form of self-development, validated by expert judges considered reliable (α> 0.75) and valid (CVI = 0.97) in their clarity and relevance. Data were tabulated by the Statistical Package for Social Sciences, version 20.0. The results show that older victims have an average age of 74.19 years old, with a prevalence of female involvement by chronic diseases, especially hypertension, average usage of 2.2 routine medications with vital signs within normal limits. The trauma prevailed during the daytime, in the residence of the victims, north of the city and on weekends. Among the mechanisms of trauma were falls, traffic accidents and physical aggression, whose most common type was brain-cerebral trauma and the main consequences were suture wounds and closed fractures. Basic Support Units were as more driven to pre-hospital care (87.8%) and the main destination place consisted of a referral hospital for emergency of the state (57.5%). Among the most commonly performed procedures by nursing staff immobilization with rigid board and neck collar and the peripheral venipuncture, and the main component used for volume replacement to saline were highlighted. There was a significant relationship between the deaths and the mechanism of injury, mechanism of injury and procedures, except medication administration procedures carried out, except immobilization and unit for service. It is highlighted the prevalence of trauma in the elderly, poor follow-up Pre-Hospital Trauma Life Support protocol and the paucity of records and nursing procedures performed. There is need for a protocol of care specific to elderly trauma victims and education strategies for the prevention of such events

Um estudo da aplicação do conceito de risco na conscientização e conhecimento de estudantes de ensino técnico sobre riscos de segurança e saúde ocupacional em laboratório de soldagem

This dissertation presents a discussion on the level of risk awareness of students who have welding practice in the laboratories at CEFET/PI, both in Teresina and Floriano. Its main goal is to investigate risk factors involving students, teachers and employees that work in these laboratories. It s an empirical survey, held among a certain amount of students from the course in Mechanic Technology. For data analysis, the concept of risk was compared to the students direct measure of perception. The main results suggest the students must be better informed, more risk aware and more competent, in order to avoid accidents. They also point to a strong need for a more formal and effective performance to assure full consciousness about the risks involving the welding practice.

A oficina como método de desenvolvimento de projeto do produto aplicado à atividade jangadeira de Ponta Negra Natal-RN

The jangadas (brazilian fishing rafts) are rudimentary artisanal vessels intrinsic to the Northeast of Brazil. The fishery with jangadas is highly representative in the State of Rio Grande do Norte, and source of income for many families in addition to being a strong cultural icon. Is still alive despite the difficulties, bringing the history and customs of the fishermen and their people. However, is in process of extinction due to factors such as the low profitability of the activity, tourism and urbanization. From the understanding of activity involving their context and circumstances, based on identified problems regarding the conditions of use of jangadas as the unpredictability, the risk of accidents, poor working conditions, hygiene and housing, this dissertation aims to: analyzing the design of the jangada on the beach of Ponta Negra and its relationship with the activity in relation to health, safety, productivity and environment, and from such assessments, together with the results achieved during the workshops of the project, proposing a cart to move the raft, adapted to the local fisherman activity studied. To perform analysis of jangadeira activity, we used a methodology based on ergonomic work analysis - AET (WISNER, 1987; GUÈRIN, 2001; VIDAL, 2008, SALDANHA, 2004 and Carvalho, 2005). For data collection were used observational and interaction methods as a conversational action, verbalizations, photographs and video. It is emphasized that the search for solutions appropriate to the jangadeira activity was possible through the collaboration of several people, not just an informational level and understanding during the work activity, but effectively contributing to the making decisions

Oportunidades de melhoria ergonômica das exigências físicas da atividade jangadeira em Ponta Negra Natal-RN

The fishing is an activity with rafts marked by unpredictability, poor tools, physical stress, awkward postures, risk of accidents and incidents, which contribute to insecurity in the context of activity. This study aimed to contribute to reducing of physical effort and the biomechanical impacts in jangadeiro activity of artisanal fishing using jangadas on the beach of Ponta Negra, Natal-RN. To achieve this purpose the methodology of the Work Ergonomic Analysis - WEA became a reference using techniques such as observational and interactional observation notes, photographs, videos, action conversational and listening verbalizations. The resulting activity in health jangadeiro, discussed in this research were: static postural assessment, flexibility of movement of shoulder flexion-extension, flexibility of the hamstrings and lower back, grip and musculoskeletal pain. It was found from observations, interactions and activity analysis, that in carrying out fishing rafts are frequent awkward postures associated with demand for power and many are already feeling the jangadeiros reflections of years of life dedicated to this work. These have already adopted some measures to manage the activity, such as job rotation during the expedition of capture. Therefore, there is a need to expand these measures of activity management, as well as design and capabilities of the raft, seeking positive changes in the activity and consequently the quality of life jangadeiro

Análise da situação de trabalho do motorista em uma empresa de ônibus urbano da idade de Natal (RN)

The problem dealt with in this study concerns the analysis of bus drivers' working situation. It stemmed from the need to identify the difficulties faced by these professionals in accomplishing the results expected by the company. A case study was carried out in a public transportation company in the city of Natal. Records and observations made in the workplace, alongside perfomance indicators, such as absenteeism tax, staff turnover and traffic accidents, revealed problems in their activity. It was made clear that, in the company being studied, absenteeism was related to health problems, particularly psychiatric and musculoskeletal disorders, and that although the indicators of traffic accidents and staff turnover have declined over the years, they are still elevated. The interviews involved 50 of the 124 drivers who worked directly in the service, and contained questions covering eleven factors related to the drivers' work. They indicated a gap between the prescribed work and the work actually done, in that there were a series of embarassing or stressful situations involving traffic, itinerary length, road conditions, vehicle maintenance, physical environment (bus terminus), job post and supervision policies. On the other hand, factors such as enjoying driving, the work itself and being with workmates positively influenced the drivers' working conditions. In the propositions of the administration and human resources subsystems, some alternatives were found in order to remodel this activity

Abordagem da ergonomia para a análise da acessibilidade de uma instituição de longa permanência para idosos da cidade de Natal-RN

This dissertation presents and discusses the results of an applied research on the accessibility of residents in a Long Term Care Institution (LTCIs) in the city of Natal- RN. The main objective of this research is to suggest projectual improvements that maximize the accessibility in a LTCIs of Natal-RN, considering the aspects of mobility, safety, comfort and independence of elderly residents. Moreover, one should consider the specific characteristics of the user population, capabilities and limitations of the biological process of aging, which causes damage to the neurological system, musculoskeletal and cardiovascular and progressively affects on visual acuity, balance and locomotion of elderly people. This research has a qualitative approach and divided into four phases: exploratory, bibliographical and documentary research, mapping of the LTCIs of Natal-RN, case study. The phase of the mapping presented an overview of accessibility on LTCIs of Natal-RN. The institution of the case study was defined based on the overall assessment of accessibility and ergonomics criteria, preceded by an application of an Ergonomic Work Analysis to understand the accessibility of the elderly people. Interactional and observational methods were used to collect field data. To this end, an intense process of social construction was conducted, involving the elderly residents, caregivers, health professionals and general servants and LTCIs´ managers. It was found that the NBR 9050 is not comprehensive to solve the diversity of accessibility problems found in LTCIs. All LTCIs investigated were in disconformity to the NBR 9050. In the case study, it was found that the inappropriate design hinders the daily activities of the elderly people and is a source of risk of accidents. The environment, facilities and lack of assistive technologies hinder the autonomy of the elderly people, and this LTCI requires ergonomic intervention to improve the accessibility, autonomy and security of the elderly people

Sistema de supervisão aérea baseado em navegação visual para detecção de anomalias em instalações de petróleo e gás

This work deals with the development of a prototype of a helicopter quadrotor for monitoring applications in oil facilities. Anomaly detection problems can be resolved through monitoringmissions performed by a suitably instrumented quadrotor, i.e. infrared thermosensors should be embedded. The proposed monitoring system aims to reduce accidents as well as to make possible the use of non-destructive techniques for detection and location of leaks caused by corrosion. To this end, the implementation of a prototype, its stabilization and a navigation strategy have been proposed. The control strategy is based on dividing the problem into two control hierarchical levels: the lower level stabilizes the angles and the altitude of the vehicle at the desired values, while the higher one provide appropriate references signals to the lower level in order the quadrotor performs the desired movements. The navigation strategy for helicopter quadrotor is made using information provided by a acquisition image system (monocular camera) embedded onto the helicopter. Considering that the low-level control has been solved, the proposed vision-based navigation technique treats the problem as high level control strategies, such as, relative position control, trajectory generation and trajectory tracking. For the position control we use a control technique for visual servoing based on image features. The trajectory generation is done in a offline step, which is a visual trajectory composed of a sequence of images. For the trajectory tracking problem is proposed a control strategy by continuous servovision, thus enabling a navigation strategy without metric maps. Simulation and experimental results are presented to validate the proposal

Implantação de um sistema de detecção de vazamentos em oleodutos com tratamento de alarmes falsos

The pumping of fluids in pipelines is the most economic and safe form of transporting fluids. That explains why in Europe there was in 1999 about 30.000 Km [7] of pipelines of several diameters, transporting millíons of cubic meters of crude oil end refined products, belonging to COCAWE (assaciation of companies of petroleum of Europe for health, environment and safety, that joint several petroleum companies). In Brazil they are about 18.000 Km of pipelines transporting millions of cubic meters of liquids and gases. In 1999, nine accidents were registered to COCAWE. Among those accidents one brought a fatal victim. The oil loss was of 171 m3, equivalent to O,2 parts per million of the total of the transported volume. Same considering the facts mentioned the costs involved in ao accident can be high. An accident of great proportions can bríng loss of human lives, severe environmental darnages, loss of drained product, loss . for dismissed profit and damages to the image of the company high recovery cost. In consonance with that and in some cases for legal demands, the companies are, more and more, investing in systems of Leak detection in pipelines based on computer algorithm that operate in real time, seeking wíth that to minimize still more the drained volumes. This decreases the impacts at the environment and the costs. In general way, all the systems based on softWare present some type of false alarm. In general a commitment exists betWeen the sensibílity of the system and the number of false alarms. This work has as objective make a review of thé existent methods and to concentrate in the analysis of a specific system, that is, the system based on hydraulic noise, Pressure Point Analyzis (PPA). We will show which are the most important aspects that must be considered in the implementation of a Leak Detection System (LDS), from the initial phase of the analysis of risks passing by the project bases, design, choice of the necessary field instrumentation to several LDS, implementation and tests. We Will make na analysis of events (noises) originating from the flow system that can be generator of false alarms and we will present a computer algorithm that restricts those noises automatically

Sistema híbrido para detecção e diagnóstico de falhas em sistemas dinâmicos

The industries are getting more and more rigorous, when security is in question, no matter is to avoid financial damages due to accidents and low productivity, or when it s related to the environment protection. It was thinking about great world accidents around the world involving aircrafts and industrial process (nuclear, petrochemical and so on) that we decided to invest in systems that could detect fault and diagnosis (FDD) them. The FDD systems can avoid eventual fault helping man on the maintenance and exchange of defective equipments. Nowadays, the issues that involve detection, isolation, diagnose and the controlling of tolerance fault are gathering strength in the academic and industrial environment. It is based on this fact, in this work, we discuss the importance of techniques that can assist in the development of systems for Fault Detection and Diagnosis (FDD) and propose a hybrid method for FDD in dynamic systems. We present a brief history to contextualize the techniques used in working environments. The detection of fault in the proposed system is based on state observers in conjunction with other statistical techniques. The principal idea is to use the observer himself, in addition to serving as an analytical redundancy, in allowing the creation of a residue. This residue is used in FDD. A signature database assists in the identification of system faults, which based on the signatures derived from trend analysis of the residue signal and its difference, performs the classification of the faults based purely on a decision tree. This FDD system is tested and validated in two plants: a simulated plant with coupled tanks and didactic plant with industrial instrumentation. All collected results of those tests will be discussed
