Esta pesquisa teve como objetivo principal identificar oportunidades de aperfeiçoamento de um método de classificação de tipos de erros humanos de operadores de linha de frente. Tais oportunidades foram identificadas com base no teste do método em acidentes em canteiros de obras, um ambiente no qual ele ainda não havia sido aplicado. Assim, foram investigados 19 acidentes de trabalho ocorridos em uma construtora de pequeno porte, sendo classificados os tipos de erros dos trabalhadores lesionados e de colegas de equipe que encontravam-se no cenário do acidente. Os resultados indicaram que não houve nenhum erro de 57,9% dos trabalhadores para os quais o método foi aplicado, constituindo evidência de que as causas estavam fortemente associadas a fatores organizacionais ao invés de fatores comportamentais ou cognitivos. O estudo ainda apresenta recomendações que facilitam a interpretação das perguntas que constituem o método de classificação de tipos de erros. / This study aimed to identify major opportunities for improving a method of classification of errors types of front- line workers. Such opportunities have been identified on the basis of testing the method in accidents at construction sites, an environment in which it had not yet been implemented. Thus, we investigated 19 occupational accidents occurred in a small-sized construction company, classifying the errors types of both injured workers and crew members who were at the scene of the accident. The results indicated that there was no error of 57,9% of workers for which the method was applied, providing evidence that the causes were strongly linked to organizational factors rather than cognitive or behavioral factors. The study also presents recommendations to facilitate the interpretation of questions that constitute the method of classification of types of errors.
