Workplace accidents involving machines are relevant for their magnitude and their impacts on worker health. Despite consolidated critical statements, explanation centered on errors of operators remains predominant with industry professionals, hampering preventive measures and the improvement of production-system reliability. Several initiatives were adopted by enforcement agencies in partnership with universities to stimulate production and diffusion of analysis methodologies with a systemic approach. Starting from one accident case that occurred with a worker who operated a brake-clutch type mechanical press, the article explores cognitive aspects and the existence of traps in the operation of this machine. It deals with a large-sized press that, despite being endowed with a light curtain in areas of access to the pressing zone, did not meet legal requirements. The safety devices gave rise to an illusion of safety, permitting activation of the machine when a worker was still found within the operational zone. Preventive interventions must stimulate the tailoring of systems to the characteristics of workers, minimizing the creation of traps and encouraging safety policies and practices that replace judgments of behaviors that participate in accidents by analyses of reasons that lead workers to act in that manner.

Compreender as características e a magnitude das causas externas (acidentes e violência) em crianças de 0 a 9 anos de idade torna-se cada vez mais importante em Saúde Pública. O objetivo do presente artigo foi analisar os atendimentos de emergência por causas externas em crianças. Utilizaram-se dados do Sistema de Vigilância de Violências e Acidentes em Serviços Sentinelas de Urgência e Emergência (Inquérito VIVA), realizado em 74 serviços de urgência do Distrito Federal e 23 capitais no ano 2009. Analisaram-se dados de 7.123 crianças: 6.897 (96,7%) vítimas de acidentes e 226 (3,3%) de violência. Em comparação às vítimas de violência, os atendimentos por acidentes foram mais frequentes entre crianças de 2 a 5 anos, de pele branca e ocorridos no domicílio (p < 0,05). Dentre os acidentes, as quedas e queimaduras predominaram no grupo de 0 a 1 ano, enquanto os acidentes de transporte foram mais frequentes no grupo de 6 a 9 anos (p < 0,001). Quanto às violências, atendimentos por negligência e agressão física predominaram, respectivamente, nos grupos extremos de faixa etária, sendo um familiar identificado como agressor (p < 0,001). Informações sobre ocorrência de causas externas em crianças podem apoiar políticas de promoção da saúde, além de orientar profissionais de saúde, educadores e famílias na prevenção destas causas.

In this preliminary study the occupational safety and health practices among flower greenhouses workers were evaluated. The study was carried out in the alto Tiete region, located at the Sao Paulo State, Brazil. Inadequate welfare facilities; poor pesticide storage, use and disposal conditions; use of highly toxic pesticides; lack of adequate data regarding pesticide use; and incorrect use and maintenance of PPE were observed in most of the visited greenhouses. These results suggest that, in greenhouses, workers may be at higher risk of pesticide exposure, due to many factors that can intensify the exposure such as the lack of control on reentry intervals after pesticide application. Specific regulations are needed to ensure better OSH practices on pesticide use and to improve working conditions in greenhouses, in order to deal with the peculiarities of greenhouse working environment. Some of the special requirements for greenhouses workers' protection are the establishment of ventilation criteria for restricted entry interval; clear reentry restrictions; and EPI for workers other than applicators that need to enter the greenhouse before expiring REI interval. Another important way to improve OSH practices among workers includes the distribution of simple guidelines on the dos and don'ts regarding OSH practices in greenhouses and extensively training interventions to change the perception of hazards and the behavior towards risk.

The harm upon the central auditory pathways of workers exposed to occupational noise has been scarcely studied. Objective: To assess the central auditory pathways by testing the long latency auditory evoked potentials (P300) of individuals exposed to occupational noise and controls. Method: This prospective study enrolled 25 individuals with normal hearing thresholds. The subjects were divided into two groups: individuals exposed to occupational noise (13 subjects; case group) and individuals not exposed to occupational noise (12 subjects; control group). The P300 test was used with verbal and non-verbal stimuli. Results: No statistically significant differences were found between ears for any of the stimuli or between groups. The groups had no statistically significant difference for verbal or non-verbal stimuli. Case group subjects had longer latencies than controls. In qualitative analysis, a greater number of altered P300 test results for verbal and non-verbal stimuli was seen in the case group, despite the absence of statistically significant differences between case and control subjects. Conclusion: Individuals exposed to high sound pressure levels had longer P300 latencies in verbal and non-verbal stimuli when compared to controls.

O estudo objetivou compreender o risco ocupacional como um processo simbólico que estrutura as atividades diárias dos profissionais da área de saúde que manipulam instrumentos perfurocortantes. Pesquisa descritiva realizada em um hospital universitário com dados coletados por meio do levantamento dos acidentes de trabalho no Centro de Tratamento Intensivo adulto e na Lavanderia, pela aplicação de um questionário a 105 profissionais de saúde. Os dados foram analisados por meio de uma perspectiva interdisciplinar para conciliar a análise quantitativa e qualitativa dos dados. Os resultados revelaram que, embora os dados indiquem baixo índice de acidentes, ainda é preciso aprimorar instrumentos como o mapa de riscos e o uso de equipamentos de segurança, bem como investir na capacitação das equipes.
