Discussão sobre a pressão sonora que acomete o trabalhador da indústria da construção civil

Brennand, Frederico de Vasconcelos 30 July 2007 (has links)
Made available in DSpace on 2017-06-01T17:57:18Z (GMT). No. of bitstreams: 1 Frederico_confrontada.pdf: 5462020 bytes, checksum: 78e28b0ea393f505f0e3617851d55d06 (MD5) Previous issue date: 2007-07-30 / The decision for the building construction industry was due to its dynamics, having diverse areas within a project, many construction workers are involved, and they are exposed to machinery and equipments noise. Machinery noise is the main cause of medical leave and injuries; it can also cause early retirements by the INSS [Brazilian National Institute of Social Security]. According to the Ministry of Labor and Employment, the civil construction sector held 1,045,251 direct job positions in 2003, and 1,118,570 direct job positions in 2004. The Ministry of Welfare points that in 2005, approximately 492,000 of work related injuries were reported to the INSS. If compared to the previous year of 2004, work related injuries increased 5.6%. The numbers show the importance of a research in that area. According to the NR-9, the noise is a physical agent, and many times do not receive the special attention required, it can go unnoticed during the implementation stages of a project. It is necessary, before the start of each job or project, the identification, evaluation and the correct control of the noise when needed. Noise is considered the third main cause of environmental pollution, only behind of water and air pollution. Hearing loss is a pathology that can be 100% prevented, but once acquired, it becomes permanent and irreversible. This research objective was the analysis by a dosimeter of the sound pressure level generated by the equipments: concrete truck mixer; the circular saw or portable and construction lift of the civil construction sector. The research took place in 5 (five) sites of vertical building projects, during the final stage, in the Metropolitan area of Recife (RMR). The results were satisfactory, as no construction worker was found exposed to the different levels of sound pressure (noise), generated by the machinery being monitored: concrete truck mixer, circular saw or portable and construction lift. Even though some levels exceeded the tolerance limit (LT) which is a standard of 85dB (A), for a 100% exposure in an 8 hours working day. Only 1 out of 14 construction workers was not equipped with the Individual Protection Equipment (EPI). In this particular case, the ear protector (protective type shell or plug type), exposed the worker to the limit set by the standard. Two (2) dosimeters from Quest brand were used in this research; models Q-300 and Q-400. The devices were connected to the body of the worker. After verifying the sound pressure levels and the exposure of each worker to such levels of noise, the results were confronted with the legislation in charge and some mitigation measures were suggested, when deemed necessary, in order to avoid possible damages to the workers health / A escolha pela Industria da Construção Civil foi devido à sua dinâmica, exibindo diversos ramos dentro de uma obra com muitos funcionários envolvidos, estando muitas vezes expostos ao ruído de máquinas e equipamentos. O ruído é considerado como um dos maiores causadores de afastamento, lesões chegando até a causar as aposentadorias, junto ao INSS. Segundo o Ministério do Trabalho e Emprego, o setor da construção civil ocupou 1.048.251 postos de trabalhos diretos em 2003, tendo ocupado 1.118.570 postos de trabalhos em 2004. De acordo com o Ministério da Previdência Social, no ano de 2005, cerca de 492 mil acidentes do trabalho foram registrados no INSS. Comparado com o ano anterior, 2004, o número de acidentes de trabalho registrados aumentou 5,6%, por isso a importância de pesquisas nessa área. De acordo com a NR-9, o ruído é um agente físico, muitas vezes esquecido, passando despercebido nas fases de execução de uma obra, se fazendo necessário, antes do inicio de cada obra, a sua identificação, avaliação e os possíveis controles quando necessário. O ruído é considerado o terceiro maior causador da poluição ambiental, só ficando atrás da poluição das águas e do ar. A perda auditiva é uma patologia 100% evitável, mas uma vez adquirida, é permanente e irreversível. Essa pesquisa teve como objetivo, a analise através da dosimetria do nível de pressão sonora, gerado pelos equipamentos: betoneira , serra circular e/ ou manual e guincho (elevador) do ramo da indústria da construção civil. Foi realizada em 5 (cinco) obras de edificações verticais, na fase de acabamento, na Região Metropolitana do Recife (RMR). Os resultados foram satisfatórios, pois nenhum funcionário encontrava-se expostos aos diferentes níveis de pressão sonora (ruídos), gerados pelas máquinas monitoradas: guincho , betoneira e serra circular ou portátil. Apesar de alguns níveis excederem o limite de tolerância (LT) que para a norma é de 85dB (A), com uma dose de exposição de 100% para uma permanência de 8 horas diárias. Apenas 1 dos 14 funcionários, não utilizava o Equipamento de Proteção Individual (EPI), no caso específico em apreço, o protetor auricular, tipo concha ou tipo plug, o que o levou a aproximar-se mais do limite estabelecido pela norma. Foram utilizados 2 (dois) dosímetros de marca Quest , modelos Q-300 e Q-400 , aparelhos estes conectados ao corpo do trabalhador. Depois de verificados esses níveis de pressão sonora e a exposição de cada funcionário a tais níveis de ruído, os resultados foram confrontados com a legislação vigente e sugeridas algumas medidas de atenuação, quando julgados necessários

A review of construction work sampling methods and an investigation into their use in South Africa

Hund, Peter J January 1987 (has links)
Work sampling had its origin in industrial engineering; however, its use in construction has increased greatly during the 1970's and 1980's. Research would suggest that most of the innovation in this field is taking place in the United States. The basic methods of Work Sampling have been developed to suit the peculiarities of the construction site as opposed to the production line or factory where it was first used. The objectives of this report are as follows: 1. To review the existing methods of Construction Work Sampling as well as discuss further aspects and problems which should be considered when undertaking a Work Sampling study. 2. To compare Construction Work Sampling with other methods of measuring productivity. 3. To evaluate by means of a case study the ease of applicability of the sampling methods to a South African construction site, and at the same time to identify differences between the description of the methods in theory and their use in practice. 4. To establish by means of a questionnaire the extent to which Construction Work Sampling methods are already in use in South Africa as well as other related information. Information for this report was obtained from journals, manuals, text books, interviews, and the case study and questionnaires mentioned.

Förbättring av arbetsmiljön med hjälp av arbetsberedning : Implementering av ett förbättringsförslag i praktiken / Improvement of the work environment using work sets : Implementation of an improvement proposal in practice

Ivarsson, Sebastian, Larsson, Rikard January 2020 (has links)
Syfte: Eftersom byggbranschen är en av de mest olycks- och dödsfallsdrabbade branscher finns det anledningar att tro att det någonstans i arbetsmiljöarbetet brister. Inom arbetsmiljö och säkerhet sker en ständig utveckling vilket påverkar hur viktigt det är med en bra kommunikation från arbetsledaren till yrkesarbetaren. Målet med studien var att identifiera kommunikationsbrister mellan arbetsledare och yrkesarbetare som kunde skapa tillfälle för olyckor och tillbud. Syftet med att göra den här undersökningen var att utveckla ett eget förbättringsförslag och implementera det i praktiken och utvärdera hur detta mottogs. Metod: Studien utfördes som en aktionsforskning där brister i dagens informationsflöde identifierades för att sedan implementera en lämplig handling för att åtgärda problemet. Efter detta utvärderades den nya handlingen. För att utföra denna undersökning och besvara frågeställningarna har flera undersökningsmetoder för datainsamlingens använts: semistrukturerade intervjuer, litteraturstudier, dokumentanalys och deltagande observationer vilka har analyserats genom en triangulering för ett trovärdigt resultat. Resultat: Informationen om de risker som identifierades i ett arbetsmoment kommunicerades genom arbetsberedningar, vilka skulle ske genom ett överlämnings möte tillsammans med yrkesarbetarna. Dagens arbetsberedningsmall upplevdes som bristfällig samt med stort rum för utveckling. I identifieringen av bristerna i dagens informationsflöde var det informationen gällande kringliggande arbeten som var mest återkommande. Detta resulterade i att förbättringsförslaget begränsades till den frågan. En ny arbetsberedning togs fram med frågeställningar berörande arbetsmoment som sker i närheten och vilka risker samt riskreducerande åtgärder som skall vidtas. Konsekvenser: Det upplevdes förekomma ett samband mellan bristande kommunikation och tillbud samt olyckor. Individers personliga inställning till arbetsmiljöfrågor ansågs vara en faktor till att det sker olyckor. Detta kunde vara en faktor till att arbetsmiljön inte prioriterades mer under arbetsberedningar och påverkade i sin tur både överlämningen samt mängden information som återkopplas till arbetsledarna. För att minska tillbud och olyckor borde yrkesarbetarna informerats om kringliggande arbeten och de risker som tillkommer. Detta bidrog även till att yrkesarbetarna kände sig mer delaktiga och involverade i frågor som berörde deras arbetsmiljö. Begränsningar: Den här studien undersökte endast kommunikationsbrister mellan arbetsledare och yrkesarbetare som påverkade arbetsmiljöns efterlevnad. Resultatet ansågs vara generaliserbart i byggbranschen. Förbättringsarbetet syftade till att förbättra redan befintliga dokument och eftersom arbetsberedningar är företagsspecifikt blir även funna brister i arbetsberedningarna det. / Purpose: Since the construction industry is one of the most harmful and lethal industries there is reason to believe that there is something wrong with the work environment planning. There is constant ongoing progress within the area of safety issues and work environment which affects how important good communication is from the supervisor to the carpenter. The objective of this study is to identify communication deficiencies between the supervisor and carpenter, which in turn raises the probability for accidents and incidents to occur. The purpose of this study is to develop an improvement proposal to implement and evaluate how it is received. Method: The study is conducted as an action research study where deficiencies are identified in today’s information channels. Furthermore, an appropriate action is proposed to address the problem, followed by an evaluation of the new action. When conducting this research, and when answering the research questions, several methods been utilized, such as: structural interviews, literature studies, document analysis, and participant observations which have been analyzed through triangulation for a credible result. Findings: The information about the risks identified in a work activity was communicated through a work sets, which was be done through a meeting with the construction workers. Today’s work set template was perceived as inadequate, with a lot of room for development. When identifying the deficiencies in today’s information flow, the information regarding surrounding work was identified as the most recurring. This resulted in the improvement proposal being limited to that issue. A new work set was made with questions regarding work activities that are taking place nearby and what risks and risk mitigation measures are to be taken. Implications: The connection between lack of communication and incidents as well as accidents was identified. An individual's attitude toward work environment issues are a factor in the occurrence of accidents. This is a factor when it comes to the work environment as it is not prioritized higher when planning work sets which affects both the handover and the amount of information that is given back to the supervisors. To reduce incidents and accidents, construction workers need to be informed about the surrounding work and the risks involved, this also makes the construction workers feel more involved in issues that affect their daily work environment. Limitations: This study only examines communication deficiencies between supervisors and construction workers regarding the work environment. The result is regarded as general to the construction industry. The improvement work is limited to improving existing documents. Furthermore, work sets are company-specific, shown deficiencies are as well.

Buller från byggarbetsplatser : En undersökning om eventuella bullerproblem för befintliga bostäder i Öster Mälarstrand i Västerås

Mohamed, Abdulahi, Ntamulenga, Bahati January 2021 (has links)
Problem background: This thesis in building technology at Mälardalen University examines the noise level of the constructions on Öster Mälarstrand. The area Öster Mälarstrand is in the eastern part of Västerås next to the water area Mälaren. This district began to build in the end of the 20th century, and the area went from an industrial field to become as described, one of the best places in Västerås to live at. The district is now an area with a large extent of residentials and other necessities such as banking, gym, cafes, restaurants, shops and a large marina. Öster Mälarstrand is still under constant construction of new buildings. The purpose of the survey is to investigate the noise level on Öster Mälarstrand, and if the construction sites are customised to the guidelines that exist regarding noise and noise levels outside in a residential area. The work is summarized and ends by giving examples of measures to reduce noise and noise levels in the area. The method is based on own noise measurements, calculations and interviews. The noise measurements carried out at three specific locations on Öster Mälarstrand during four working days when constructions were underway. Interviews have also been conducted with 50 people who live in the area. The calculations of the noise measurments showed several varying values, but one thing that is clear is that the noise calculations that was executed, exceeds the guideline values set for noise-levels in Öster Mälarstrand. The interviews that were conducted presents that a majority of the interviewees thought that the noise level of the constructions on Öster Mälarstrand was disturbing, especially now during the pandemic of Covid-19, when several people started working from home. The conclusion in this thesis is that noise levels exceeds the guideline values ​​that exist according to the Swedish Environmental Protection Agency. The interviews in the area show that the majority of the participants experience the noise from the construction site as a disturbance.

Shima Jahani (16648824) 31 July 2023 (has links)
<p>  </p> <p>Noise-induced hearing loss (NIHL) is a significant occupational health concern in the construction industry, necessitating effective hearing protection for workers. This project explores the detrimental consequences of environmental pollutants, specifically noise pollution common in construction settings. The research incorporates user interviews with construction workers and managers to identify challenges and motivations surrounding the use of hearing protection devices.</p> <p>My findings underscore the necessity of addressing pollution in the construction industry to safeguard the well-being of workers. Noise pollution emerges as a primary concern, leading to hearing loss, stress, decreased productivity, and safety hazards. The research revealed that workers grapple with obstacles, including discomfort, lack of awareness, and cost barriers, while also recognizing driving forces, including fear of hearing loss and the encouragement of supervisors. The design process involved thorough research, including a literature review, competitive analysis, and semi-structured user interviews, resulting in an advanced hearing protection device that prioritizes effective communication, cleanliness, and user comfort. The final product incorporates innovative features such as lighting indicators, a compact charging case, strategically positioned buttons, secure fit with magnets, and a range of color options.

Evaluating a Sustainable Community Development Initiative Among the Lakota People on the Pine Ridge Indian Reservation

Mosman, Sarah A. 12 1900 (has links)
This thesis details my applied thesis project and experience in the evaluation of a workforce development through sustainable construction program. It describes the need of my client, Sweet Grass Consulting and their contractual partner, the Thunder Valley Community Development Corporation, in the evaluation of Thunder Valley CDC's Workforce Development through Sustainable Construction Program. My role involved the development of an extensive evaluation package for this program and data analysis of evaluation materials to support Thunder Valley CDC's grant-funded Workforce Development Program. I place the efforts of Thunder Valley CDC in the context of their community, the Pine Ridge Reservation of the Lakota People, and within an historical and contemporary context to highlight the implications of the efforts of Thunder Valley CDC. Using the theoretical frameworks of cultural revitalization and community economic development, I attempt to highlight two important components of Thunder Valley CDC's community development efforts - cultural revitalization for social healing, and development that emphasizes social, community and individual well-being. Thunder Valley CDC's Workforce Development through Sustainable Construction Program is still in its early stages, and so this first year of implementation very much represented a pilot phase. However, while specific successes are difficult to measure at this point, general successes are viewable in the daily operations of Thunder Valley CDC that exemplify their stated mision and goals. These successes include initiatives that holistically address community needs; relevancy in the eyes of the community they serve; support for the community and for Program participants' unique challenges; and a cultural restoration and revitalization emphasis that underlies and strengthens all of this. The program thus has the potential to provide a model for community development by challenging dominant "development" paradigms and utilizing community resources and assets for community development that reflects the community's values and worldviews.

Formação profissional dos trabalhadores da construção civil: o canteiro de obras e a emancipação social / Professional education of construction workers: the construction site and social emancipation

Diederichsen, Francisco Toledo Barros 14 December 2017 (has links)
A presente tese de doutorado aborda a formação profissional dos trabalhadores da construção civil com objetivo de contribuir com experiências pedagógicas alternativas à sua atual condição heterônoma e oprimida de trabalho, por meio de ensaios experimentais, no formato de \'canteiro escola autogestionário\'. Essas práticas levantaram questões e revelaram lacunas de conhecimento da história das modalidades alternativas unitárias e integrais de educação. Pesquisamos exemplos de escolas e espaços de ampliação da autonomia dos construtores como contribuição para sua emancipação social e política. Nos perguntamos como chegamos a atual separação das profissões, divididas entre teóricas - arquitetos - e práticas - operários. Em busca de sua genealogia, abordamos as primeiras sociedades de classe, na antiguidade, e os primeiros espaços formativos duais, que separam a formação das elites para direção da sociedade - educação liberal e teórica, das classes subalternas - educação prática para o trabalho. A formação de arquitetos e construtores se deu de modo particular nas sociedades de classe: há momentos de formação dual onde arquitetos apreendem seu ofício distante das práticas construtivas, sem uso de sua força de trabalho, a formar \"arquitetos sem construção\", e os construtores apreendem seu trabalho nas oficinas, sem controlar a produção da arquitetura, numa relação dialética, dominados por arquitetos. Noutras sociedades, a formação de arquitetos se dá pela experiência prática físico-corporal na produção material da arquitetura, quando desenvolvem o ofício do desenho, e da representação. É ali, no canteiro de obras que formam-se \"arquitetos com construção\", de origem popular, compondo coletivos autônomos que idealizam e constroem. Na invasão das Américas os europeus treinaram os povos escravizados a construir com estéticas européias. Ergueram edifícios com trabalho heterônomo, oprimido e explorado - salvo exceções como nas Missões Jesuíticas. Com o avanço das forças produtivas no século XIX, criaram Liceus assistenciais, para \"qualificar\" construtores com apoio de trabalhadores italianos. Nesse período - 1870 a 1914, São Paulo - as elites não perceberam que a qualificação artística ampla e autônoma dos construtores resultaria em mobilizações por direitos trabalhistas. Quando se deram conta, recusaram os italianos anarquistas e os capomastri coletivistas construtores do ecletismo paulistano, e apoiaram tecnologia que exclui o trabalhador da criação: o concreto armado. É período de desqualificação e treinamento do trabalhador. Para formar os nacionais, criam a educação empresarial: \"Sistema S\" e em 1964 dão o golpe civil militar, que perdura até 1988. Com a redemocratização ampliam-se experiências formativas autogestionárias, e políticas publicas socializantes até 2016 - golpe midiático parlamentar. Foram 28 anos que permitiram experiências de \"educação de trabalhadores por trabalhadores\", como ensaiado nos \'canteiro escola\' com movimento popular, o MST, e universidade, a USP. Edificamos a \'casa das artes\', na ENFF - Guararema, com técnicas agroecológicas de construção e uma \'viela publica\' no Parque dos Químicos - São Bernardo do Campo, com técnicas compensatórias de drenagem urbana. Os ensaios praticaram as idiossincrasias da formação libertária dos trabalhadores da construção percebidas no levantamento do processo histórico. Essa vivência nos permitiu identificar que os \'canteiro escola\' contemporâneos se inserem nas tradicionais linhas de ação popular pela emancipação da classe. / The present doctoral thesis deals with the professional education of construction workers with the objective of contributing to pedagogical experiences that are alternative to their current heteronomous and oppressed work conditions, through experimental tests in the form of \'construction site - self - managed school\'. These practices raised questions and revealed gaps in knowledge of the history of alternative and unitary modes of education. We have explored examples of schools and spaces for the expansion of the autonomy of the constructors as a contribution to their social and political emancipation. We wonder how we came to the current separation of professions, divided between theoretical - architects - and practices - workers. In search of their genealogy, we approach the first class based societies in antiquity and the first dual formative spaces, separating education of the elites for the direction of society - liberal and theoretical education, and the subaltern classes - practical education for work. The education of architects and builders takes place particularly in class based societies: there are societies where the formation is dual where architects learn their craft away from constructive practices, without using their work force, to create \"architects without construction\", and The builders apprehend their work in the workshops, without controlling the production of architecture, in a dialectical relationship dominated by architects. In other societies, the formation of architects is due to the physical-corporal practical experience in the material production of architecture, when they develop the office of drawing, and in representation, it is at the construction site that they form \"architects with construction\", of popular origin. They are autonomous professionals who idealize and build. In the invasion of the Americas by Europeans the elites trained enslaved people to build with European aesthetics. They erected buildings with heteronomous work, oppressed and exploited. With the advance of productive forces in the nineteenth century, they created assistencial Liceus, to \"qualify\" builders with the support of Italian workers. In this period - 1870 to 1914, São Paulo - we verified that they did not realize that the broad and autonomous artistic qualification of the builders would result in mobilizations for labor rights. When they realized it, they refused the Italian anarchists and the capomastri collectivists builders of the São Paulo eclecticism, sponsoring technology that excludes the worker from creation: the reinforced concrete. There is a period of disqualification and training of the worker. \"National System\" is created, and in 1964 the civilian military coup has place, and lasts until 1988. With redemocratization, self-managed formative experiences and socializing public policies are extended to 2016 - year of media-partisan coup of the elites. These 28 years have generated experiences of \"education of workers by workers\", as rehearsed in the \"construction site school\" with popular movement, the MST, and university, USP. We built the \'house of arts\' at the ENFF - Guararema, with agro-ecological construction techniques and a \'public gallery\' at the Chemical Park - São Bernardo do Campo, with compensatory urban drainage techniques. The essays practiced the idiosyncrasies of the libertarian education of construction workers perceived in the survey of the historical process. This experience allowed us to identify the contemporaries \'construction site schools\' fall within the traditional lines of people`s action for the emancipation of the class.

Perfil audiométrico de exames admissionais em trabalhadores da construção civil da Bahia / A study of the civil construction workers audiometric profile upon admission in the state of Bahia (Brazil)

Fonseca, Ana Maria Pimenta da 10 October 2007 (has links)
Made available in DSpace on 2016-04-27T18:12:24Z (GMT). No. of bitstreams: 1 Ana Maria Pimenta da Fonseca.pdf: 566657 bytes, checksum: 4943537ba9730854c7867eec02d30707 (MD5) Previous issue date: 2007-10-10 / The goal of this study was to investigate and analyze the civil construction workers audiometric profile upon admission in the State of Bahia (Brazil) from 1999 to 2005. Methods: Audiometric tests (n=5702) were carried out among male workers (age range: 18 to 72) upon admission when applying for several job positions in 43 civil construction companies. Audiograms was classified into three groups: normal , indicating noise-induced hearing loss (NIHL) and other causes , and were later rated as to the presence/absence of audiometric notches. Results: Normal hearing thresholds were found in 3949 (69.3%) workers, 920 (16.2%) of them showed audiograms indicating NIHL, and other alterations were found in 833 (14.6%) subjects. Although 980 (17.2%) workers did not report noise exposure, 4722 (82.8%) subjects reported at least one year of such exposure. The use of hearing protection devices was reported by 2483 (43.5%) subjects in contrast with 3219 (56.0%) workers who did not use it. Workers exposed to chemicals totaled 1084 (19%) against 4618 (81%) nonexposed ones. Audiometric notches were found in 1684 (29.5%) subjects in the normal group, 919 (16.1%) subjects in the NIHL group and 774 (13.4%) subjects in the other causes group. Conclusions: The prevalence of audiometric alterations was found to be 30.7%, among which 16.1% indicated NIHL and 14.6% were rated as other causes . Increased age, more than 5 years of noise exposure, lack of use of hearing protection devices and exposure to chemicals were associated to the hearing losses found in the sample. The prevalence of audiometric notches in this population was 59.3%, of which 30.9% were unilateral and 28.4% were bilateral. Besides being associated to age, exposure time and job position, notches were more prevalent in the NIHL group and in the other causes group / O presente estudo tem como objetivo investigar e analisar o perfil audiométrico nos exames admissionais em trabalhadores da construção civil na Bahia, no período de 1999 a 2005. Método: Foram avaliadas 5702 audiometria admissionais de trabalhadores do gênero masculino, que faziam processo seletivo em 43 empresas da construção civil. A faixa etária estava entre 18 e 72 anos. Os trabalhadores realizaram exames pré-admissonais para as mais diversas funções da construção civil. Os audiogramas foram classificados em três grupos: normais, sugestivos de PAIR e outras causas. Posteriormente, também foram classificados segundo presença ou ausência de entalhe audiométrico. Resultados: 3949 (69,3%) trabalhadores apresentaram limiares dentro da normalidade, 920 (16,2%) apresentaram alteração sugestiva de PAIR e 833 (14,6%) trabalhadores apresentaram outras alterações. Dentre esses, 980 (17,2%) trabalhadores não relataram exposição a ruído e 4722 (82,8%) tinham tempo de exposição a ruído de, no mínimo, um ano. Quanto ao uso de protetor auricular (EPI), 2483 (43,5%) faziam uso e 3219(56,%) não faziam uso. Em relação à exposição a produtos químicos, 1084(19%) estavam expostos e 4618 (81%) não estavam expostos. O entalhe audiométrico esteve presente em 1684 (29,5%) trabalhadores do Grupo Normal, 919 (16,1%) no Grupo PAIR e 774 (13,4%) no Grupo Outros. Conclusões: A prevalência de alterações audiométricas foi de 30,7%, sendo 16,1% sugestivas de PAIR e 14,6% de outras causas. O aumento da idade, tempo de exposição a ruído superior a cinco anos, não uso de protetores e exposição a produtos químicos foram associados às perdas auditivas encontradas na população. A prevalência de entalhe audiométrico na população foi de 59,3%, sendo 30,9% unilateral e 28,4% bilateral. Os entalhes foram associados à idade, tempo de exposição e função exercida; além de ocorrerem mais nos Grupos PAIR e Outros
